The Definitive Guide to Carb Cycling

The Definitive Guide to Carb Cycling

Is the carb cycling diet effective for fat loss and muscle growth? Is it better than traditional dieting? Read on to find out!


Like intermittent fasting, the carb cycling diet has some pretty big shoes to fill if you listen to its more fervent advocates.

According to them, carb cycling delivers the holy grail of bodybuilding: rapid fat loss while preserving, or even building, muscle. The more ridiculous claims go even further, enticing you with promises that you won’t have to count calories, and the allure of the high-carb day, wherein you stuff yourself silly with precious carbohydrates.

Another common selling point of the carb cycling diet is the claim that a traditional approach to dieting (steady protein, carbohydrate, and fat intake throughout the week, with planned cheats/refeeds) simply can’t get you to the “super lean” category (6% and under for men, 16% and under for women) without burning up a ton of muscle.

Well, in this article we’ll not only dive into what carb cycling is and how you do it, but we’ll also cut through the hype and hyperbole surrounding the matter and use a bit of science and anecdotal experience to get at its heart.

What is the Carb Cycling Diet?

what is carb cycling

The carb cycling diet is very simple. It works like this:

  • Throughout the week, you rotate through high-carb, moderate-carb, and low/no-carb days.
  • All days require a high protein intake.
  • Your fat intake is inversely related to your carbohydrate intake. That is, your fat intake is low when your carbs are high, and vice versa.

Exact protocols vary in terms of specific numbers, but all are based on that simple structure. For example, you may do 4 low-carb days, followed by a high-carb day, and then a no-carb day, and then start over. Or you may do 3 low-carb days followed by 1 high-carb day, and then back to the low-carb and so on.

Here’s what these days often look like numerically:

  • A high-carb day will generally have you eating 2-2.5 grams of carbohydrate per pound of body weight. Your protein intake will be around 1 gram per pound, and your fat intake between 0-.15 grams per pound.
  • A moderate-carb day will call for about 1.5 grams of carbohydrate per pound of body weight. Your protein intake will be between 1-1.2 grams per pound, and your fat intake around .2 grams per pound.
  • A low-carb day will call for about .5 grams of carbohydrate per pound of body weight. Your protein intake will usually increase to about 1.5 grams per pound, and your fat intake to around .35 grams per pound.
  • A no-carb day means less than 30 grams of carbohydrate per day. To achieve this, you basically can only eat a few servings of vegetables per day. Protein intake is around 1.5 grams per pound, and fat intake goes up to .5-.8 grams per pound.

The theory behind the diet is as follows:

Your high-carb day will refuel your muscles’ glycogen levels and flood your body with insulin, which has anti-catabolic effects (but not true anabolic effects like some people claim–insulin does not induce protein synthesis, but rather inhibits muscle breakdown). Most protocols recommend that you do your toughest workout on your high-carb day.

Your moderate-carb day gives you plenty of carbs to maintain glycogen stores, but doesn’t put you in enough of a caloric deficit to cause much weight loss. You train on these days.

Your no- and low-carb days are the days where you’re in a caloric deficit, and where some people claim the “magic” happens. These are the days where you “trick” your body into burning fat at an accelerated rate by keeping insulin levels low. It’s usually recommend that you use cardio or rest days for now/low-carb days, but if you lift more than 3 days per week, you will have to lift on 1 or more of these days. (Which sucks–more on this later.)

So, that’s how to do it. Let’s address the next question on your mind: does it work?

Is Carb Cycling Good for Weight Loss?

carb cycling for weight loss


Can you use carb cycling to lose fat? Absolutely

Any dietary protocol that puts you in a caloric deficit, whether it’s daily or weekly or even monthly, will result in weight loss, regardless of the macronutrient breakdown.

Let me state this again:

So long as you keep yourself in a caloric deficit–meaning you give your body less energy than it expends–you will lose weight, regardless of whether the energy comes from protein, carbohydrate, or fat.

Part of the appeal of carb cycling are the claims that you don’t have to “count calories” or really “watch what you eat.” You simply follow a set of simple rules regarding eating “a lot” of carbs on high days, less on moderate days, and very few on no/low days.

This loose style of dieting works decently for maintenance, and may work for weight loss to a degree, but never works for getting shredded.

Getting below 8-9% body fat (men) or 18-19% (women) requires that you plan and track your macronutrient intake closely. Period. You need to know exactly how much protein, carbohydrate, and fat you’re eating every day, and you need to manipulate these numbers to keep yourself in enough of a caloric deficit to continue losing fat, but not so much that you sacrifice muscle.

So the question of carb cycling and weight loss becomes…

Is Carb Cycling Better for Weight Loss Than Traditional Dieting?

carb cycling for weight loss bodybuilding

Enthusiasts of the carb cycling diet will claim that your low-carb days will greatly accelerate your fat loss over what it would be with a traditional approach to dieting.

Unfortunately, science isn’t on their side.

Let’s start with a study conducted by the University of Pennsylvania, which had 63 obese adults follow one of two diets:

  • A low-carbohydrate, high-protein, high fat diet. This consisted of 20 grams of carbohydrate per day, which gradually increased until target weight was achieved.
  • A conventional diet where 60% of calories came from carbohydrate, 25% from fat, and 15% from protein.

The result: the low-carbohydrate group lost more weight in the first 3 months, but the difference at 12 months wasn’t significant.

The 3-month result isn’t surprising, considering the fact that reducing carbohydrate intake reduces water retention, and also decreases the amount of glycogen we store in our liver and muscles, which further decreases total body water retention. This, of course, causes a rapid drop in weight that has nothing to do with burning fat (and anyone that has reduced carbohydrate intake as a means of cutting calories for weight loss has experienced this).

Next is a study conducted by Harvard University on diet composition and weight loss. Researchers randomly assigned 811 overweight adults to one of four diets:

  • 20% of calories from fat, 15% from protein, and 65% from carbohydrate.
  • 40% from fat, 15% from protein, and 45% from carbohydrate.
  • 40% from fat, 25% from protein, and 35% from carbohydrate.

The result: after 6 months, participants assigned to each diet had lost an average of 6 kg, began to regain weight after 12 months, and by 2 years, all had lost an average of 4 kg. Researchers concluded the study with the following (emphasis added):

“Reduced-calorie diets result in clinically meaningful weight loss regardless of which macronutrients they emphasize.”

study published by Arizona State University found that an 8-week high-carbohydrate, low-fat, low-protein diet was equally effective in terms of weight loss as a low-carbohydrate, low-fat, high-protein diet.

Particularly relevant to this post is another study conducted by Arizona State University, wherein researchers pitted a ketogenic diet (a very low-carbohydrate diet) versus a traditional diet to see if one had a metabolic advantage over the other.

In this study, 20 overweight adults were randomly assigned to one of two diets:

  • A ketogenic diet, consisting of 60% of calories from fat, 35% from protein, and 5% from carbohydrate.
  • A traditional diet, consisting of 30% of calories from fat, 30% from protein, and 40% from carbohydrate.

After 6 weeks, the results were as follows:

  • No significant difference in total weight loss.
  • Hunger ratings improved for both diets with no difference between them. This strikes at a claim often made to sell carb cycling, which is that it blunts hunger better than traditional dieting. According this study, that isn’t true.
  • Resting energy expenditure went up for both diets, with no difference between them. The low-carb diet failed to provide any special metabolic boost.
  • Insulin sensitivity was improved in both diets, with no difference between them. This is yet another blow to the low-carb trend that’s taking the fitness world by storm. The fact is weight loss in and of itself is effective at improving insulin sensitivity, regardless of diet composition.

So, what you should take away from this section of the article is that the theory that low-carb days deliver the big fat loss punch of carb cycling are not supported by literature. They are simply part of the marketing pitch.

Before we move on, however, I’d like to mention that there is a scientifically supported exception to the above statement. That is, there are cases where some people do lose more fat by reducing carbohydrate intake (and the flip side is true as well–some people lose more fat by increasing carbohydrate intake).

How does that work and why? Check out my article on carbohydrates and weight loss to learn more about it.

For the purposes of this article, however, just know that some people’s bodies have problems digesting and using carbohydrates properly. This is due to impairments in insulin production and processing.

For those people, reducing carbohydrate intake can help with weight loss. In my experience, however, this isn’t very common, and problems with insulin production and sensitivity can be vastly improved with diet and exercise.

 Some Anecdotal Support for Traditional Dieting

does carb cycling work

I both advocate and use a traditional approach to dieting because it’s simple, and it works very well when you do it right. The best diet is the one you can stick to, and you can get as lean as you want with traditional dieting.

Don’t believe me?

Well, I just finished an 8/9-week cut using a traditional diet (40% of calories from protein, 40% from carbohydrate, and 20% from fat).

I lost about 13 pounds and went from ~9% to ~6%, and my strength increased for the first 4-5 weeks, and then decreased back to my pre-diet numbers over the course of the last several weeks (and this was simply because I had to gradually reduce my calories, and I chose to pull from carbs–this makes workouts harder).

Here are a couple pictures of how I currently look:

Can You Use Carb Cycling to Lose Fat and Build Muscle Simultaneously?

carb cycling for muscle gain

The short answer?


But it’s not the carb cycling per se that would make this possible. It would be your current level of conditioning, your training history, and your genetics.

For instance, I email with scores of guys and gals every day that are losing fat and building muscle on my Bigger Leaner Stronger and Thinner Leaner Stronger programs, but they usually fit a certain profile:

  • They’re usually pretty out of shape to begin with, and have a fair amount of fat to lose.
  • They haven’t lifted weights before, or haven’t lifted anywhere near properly before. They’ve never focused on lifting heavy weights, compound lifts, progressive overload, etc.
  • They never quite knew what they were doing with their diets. Most have simply tried “eating clean,” but have never calculated, tracked, and manipulated macronutrients properly.

Under those circumstances, I actually expect people to both lose fat and build muscle while following my programs. But I don’t try to claim it’s because of the magical quantum mechanics of my methods like some carb cycling hucksters. It’s simply because the body responds incredibly well to proper diet and training, and especially in the beginning. Newbie gains are real, and are a lot of fun.

But if you’re an advanced lifter that is approaching your genetic potential, I can guarantee you that you will not  build muscle while losing fat without steroids, regardless of what you do in the kitchen or gym. What you can strive for, however, is maintaining the muscle you have by never putting yourself into too deep of a deficit, and not going overboard with too much steady-state cardio.

Another aspect of this “metabolic advantage” claim for carb cycling is that your high-carb day will give your body an “anabolic, muscle building boost” while simultaneously “shocking” your metabolism into high-gear, thus accelerating fat loss.

As you probably expect by now, these claims just aren’t supported by science.

I mentioned earlier that insulin can help preserve lean mass, but does not induce muscle growth, and any metabolic boost that comes with increased caloric intake is offset by the extra calories themselves. That is, you can speed your metabolism up by eating more, but never to a point where you’re burning the extra calories consumed plus  additional fat.

Also relevant to this claim in the fact that most people basically feel like shit on their no/low-carb days. If you want to know what carb cravings are really like, eat less than 50 grams of carbs per day for a week.

Training on a no/low-carb diet is even worse, and 1-2 higher carb days is not enough to offset this. If you want to drag ass and have basically the worst workouts ever, try to lift with any intensity on a no/low-carb day. Furthermore, a big part of maintaining lean mass while cutting is continuing to lift heavy weights and maintaining your strength, and drastic reductions in carbs make this impossible.

“Fuckarounditis” and the Bigger Picture

skinny weakling

The bigger issue here is what Martin Berkhan called “fuckarounditis.” If we want to be more politically correct, we can call it “shiny object syndrome.”

That is, too many people are looking for magic bullets, quick fixes, advanced body hacks, and other nonsense to reach their goals. One week they’re following the Rebel Max Anabolic Anaconda Program, the next the X-Physique Metabolic Recomposition Program, and on, and on.

I have sympathy, but they’re basically the hipsters of the lifting community. They’re drawn to whatever is trending, whatever’s buzzworthy. And they’re always stuck in a rut.

I get emailed every day by people afflicted with fuckarounditis. It usually goes something like this:

“Hey Mike

“I’m currently following an intermittent fasting protocol combined with some carb cycling and backloading. In the gym I’m training twice per day on a power/hypertrophy triple-split, and I’m periodizing with volume training. Why am I not big and lean like you? What type of cutting-edge protocols do you follow?”

My reply usually leaves them a little baffled. I share my secrets:

  • I lift heavy ass weights 5 times per week. Pretty much every set I do for every muscle is with weights that allow for no more than 6 reps. Check out my post on the hardgainer myth to learn more about why.
  • I stick mainly to compound movements like the squat, deadlift, bench press, and military press. My isolation work is simply to prevent physique imbalances (side and rear lateral raises, and arms training).
  • I always push myself to beat my last week’s numbers, even if it’s only by one rep. Progressive overload is key.
  • I eat a lot of protein and carbohydrates, and enough healthy fats to maintain health. If I want to lose fat, I put myself in a mild caloric deficit. If I want to maintain my body fat percentage, I eat (more or less) what I burn every day. And if I want to focus on building muscle, I put myself in a mild caloric surplus. My meal plan fits my dietary needs, schedule, lifestyle, and food preferences, and I stick to it. Period.
  • I stay patient. I’m not looking for overnight results. I’m looking for small, weekly or bi-weekly improvements that, in time, add up to big changes.

That’s it. That’s all it takes.

Resist the allure of shiny objects. Don’t contract fuckarounditis.

So Should You Give Carb Cycling a Go?

carb cycling gains

I’ll make this section short and sweet:

If you know your body doesn’t do well with carbohydrates, then carb cycling may help you lose weight. Otherwise, don’t bother with it. It doesn’t deliver on its exaggerated claims, and training and, well, living on a no/low-carb diet sucks.

    Mike, I agree with you that you can lose weight on virtually any diet that puts you in a caloric deficit, at least, for a time. Roman Malkov wrote the definitive book on carb cycling, based on his experience as a nutritional adviser to the Russian Olympic team. Lean tissue conservation is the main reason Dr. Malkov used it with Olympians. I’ve used carb cycling for years to help my fitness clients bust through stubborn weight loss plateaus. It works. Anyone who wants to know more about it from a scientific perspective should read Malkov’s book for the why of carb cycling.

    • Michael Matthews

      Thanks Mike! I’ll check out the book.

      The most common reasons why carb cycling helps people bust through weight loss plateaus are:

      1. They lose water weight due to the reduction in carb intake.

      2. They are forced to drastically reduce their caloric intake.

      The only exceptions that I run into here and there are people that are lean (8-9% in guys, 17-18% in girls) that want to get super lean. Sometimes people in these circumstances need to drop carbs quite a bit to lose the last bits of stubborn fat…

      • Mohanned Afeef

        No it is not the caloric deficit alone. Studies show that subjects do actually lose fat on carb cycling. Also, a study that compared two identical diets in caloric intake but which differ in their macro breakdown (high fat/low carb vs high carb/low fat) found that subjects in the high fat/low carb lost more weight and more fat. So, it isnt a caloric deficit only. Fat Loss/Weight Loss is more of a biochemical process than it is a physical process (Cals In/Cals Out).

        • Adam Clancey

          Can you please link to those studies? I’m sure we’d all love to read them ourselves.

        • Michael Matthews

          Of course people lose fat when they cycle carbs IF they’re also in a deficit.

          And studies go back and forth on whether low-carb or high-carb is best. I talk about it here:


  • JohnKov


    I agree with your “shiny object” standpoint totally. However, intermittent fasting can work wonders for some people, diabetics in particular.

    I am a type 2 diabetic and have been following your Bigger, Leaner, Stronger program for about 4 months now. While I have seen vast improvements in strength and body composition, I was still struggling with keeping my blood sugar levels down. The problem with this, which I am sure you are aware of, is that the higher my sugar levels, the more likely my body is to store fat.

    Since starting the intermittent fasting, I have had amazing progress in controlling my sugar levels. To the point that I have gone off medication all together and have had fasting sugar levels in the morning in the normal range for a non-diabetic!

    It is a little more difficult to do my workouts because I am still lifting heavy 4-5 days a week and I have not eaten before I go to the gym. However, I am determined to make the combination of your program and my new eating lifestyle work.

    My goal when I first started my fitness journey was to train my body to the point of almost reversing my disease. I would say at this point that I am well on my way!


    • Michael Matthews

      Thanks John! I’m really glad IF is working well for you. I actually support the use of IF:

      https://www.muscleforlife.com /the-definitive-guide-to-intermittent-fasting/

      I was just using it as example of what people will try in the belief that it will somehow make building muscle and losing fat much easier.

      That’s amazing regarding your blood sugar levels. Keep it up and I won’t be surprised if you completely handle the condition. I’ve spoken with quite a few people that have.

      Regarding the fasted lifting, are you doing BCAAs before? This is important. 10 grams before training, and a good post-workout meal.

      Again, keep it up. I’m excited for you!

      • JohnKov

        Yes, taking 15g when I wake up. My schedule goes as follows:
        BCAA’s at 7am, workout at noon, 5 more grams of BCAA’s and 3g of creatine immediately following workout. First meal at 2pm.
        It’s working wonders.

        • Michael Matthews

          That’s good. Not to nitpick, but I would recommend doing 10 grams BCAAs before your training, and then 10 grams after, and then eat at 2 pm. The BCAAs at 7am aren’t so important because you’ll have aminos still being released from your final meal of the previous day if it contained any amount of protein…

          • JohnKov

            Ok. Thanks for the advice!!

          • Michael Matthews


  • Jenny Leadem

    Great article as always. This one really gets me pumped. My mom is one of those drawn to “shiny objects”. I can’t stand people who make excuses instead of just accepting what you have to do and doing it, no way around it. When you de-bunk this stuff it just reaffirms that I need to keep at it and work harder each day!

    • Michael Matthews

      Thanks Jenny! Really glad you liked the article.

      Haha yeah many people are drawn to the shiny objects. Help her through it though!

      Yup, just keep up the good work. You’re doing great.

  • Roseann

    Good information, you know your stuff. It was nice to hear from a body builder that you don’t support a no or low-carb diet, and support a healthy diet with healthy numbers of carb, protein, and fat grams. A caloric deficit does do wonders….


    • Michael Matthews

      Thanks Roseann! I hate no/low-carb dieting and avoid it all costs. That said, it does have its place in contest preparation, but that’s only for about one week before the show.

      Yup, a mild deficit, proper exercise, and patience is all it takes.

  • Joe

    Dude you have a 5 pack!!!

    • Michael Matthews

      Hahah my ab genetics fail me. :(

  • rene

    Hi, mike, i was wondering how many calories did you eat while cutting at 40/40/20? thanks

    • Michael Matthews

      I started around 2400 and that took me from about 9% to 7.5% or so, and then reduced my calories 100 per week for 4 weeks to lose the final 1-1.5%.

  • Skylar

    Great stuff here, someone who does his research.

    • Michael Matthews

      Thanks Sklyar!

  • Andy

    Mike, what’s your opinion about carb backloading?

    • Michael Matthews

      Not into it. I’ll be writing an article on it soon.

  • Illysa Hamlin

    Would you recommend the 40/40/20 for females wanting to get low body fat as well, just with less calories?

    • Illysa Hamlin

      Also, perfect timing on this great article – I was getting ready to institute carb cycling this month and after reading this I think I’ll save myself the headache! Another outstanding read.

      • Michael Matthews

        Thanks! Good call I think. It’s just not necessary.

    • Michael Matthews


      Generally speaking, you want to have between 1 – 1.2 grams of pro per pound of body weight, around .2 – .25 grams of fat per pound of body weight, and the rest of your calories from carbs.

      That’s about a 40/40/20 split unless you’re eating a LOT of food.

      • Berry

        Hi Mike,

        how do you calculate your macro percentages, previously i would make the school boy mistake and use MyFitnessPals macro percentage calculator. sorry i am slightly a noob, so i havent found the correct maths to manually calculate Macro percentages.

  • Wildan

    Excellent article Mike!

    I especially like your take on diet trends, showing how there are no such things as sixpack shortcuts. :p

    During the most of the summer I used carb cycling and it works but not for the reasons alot of people believe it does. My experience shows me that on the days I ate low carb I would eat a significally less amout of calories opposed to my high carb days. If I wouldn’t have counted my calorie intake I would’ve fooled myself believing I ate more than I actually did. Same goes for Intermittent fasting as well, if I shorten my eating window I naturally eat less, which simply creates a caloric defict and not a magic pill. 😉

    I would greatly appreciate your input on my current carb cyling routine:
    The average macros across the week are 30% fat, 30% carbs, 40% protein, spread differently across the week.
    On weekends I would consume 20f/60c/20p at 2400 kcal which is a slight caloric surplus for me.
    On monday and tuesday I’d still be pretty carbed up from the weekend so I’d eat 60f/10c/30p, again at 2400 kcal.
    Wednesday however I make it my fasting day and do not eat anything and I would leave it as a rest day for weightlifting too.
    On Thursday and Friday I switch to a caloric deficit at around 75% of the calories from the eating days, taking 10f/20c/70p ~1800 kcal which feel more like 2500-3000 kcal because of the protein abundance, sometimes I have to force myself to reach the caloric goal. Worst days for hitting the iron, because my glycogen is usually totally depleted and 20% carbs are quite limiting even if I consume them prior to my workout. On the weekend I’d start with the cycle from the begining and carb up again.

    Technically this way I’m cutting only on 3 days out of 7 but with a deficit of around 400-500 kcal/day (weekly average as 4 days are surplus). Doesn’t seem like much but I’ve been able to shed my bodyfat on a steady basis as well as retain my muscle mass and improve my lifts.

    As a big fan of Brad Pilons Eat Stop Eat mindset my main reason why I do this kind of cycle instead of daily caloric deficit is that with high fat days my HGH level rise and allow me to do a 32 hours fast once a week, with no muscle loss at all. I do seem a bit flat on wed-fri but as soon as I carb up again my muscles look full again.
    How would you see this kind of routine and would you recommend some tweaks?

    Thank you and greetings from Austria!

    • Michael Matthews

      Thanks! Glad you liked it.

      Yup you’re totally right on the calories point. Low-carb is an easy way to restrict calories, as is IF.

      Your setup is technically good for a recomp approach. I don’t see any major flaws other than I would personally be in a surplus on training days, not rest days (unless you train on the weekend).

      How has your body been responding though? The reason I ask is I just haven’t really run into any natural weightlifters that can pull off the type of recomp that inspires people to try, you know?

      ESE is pretty good. I prefer Berkhan’s model though.

      • Wildan

        You’re right, with this schedule I also think that it’s best to train on surplus days. As I have most of my freetime on weekends I decided to make them my carb- and heavy training days so I do legs on sat, chest on sun, back on mon, biceps/triceps on tue and minor support muscles like delts and forearms on one of the caloric deficit days.

        As the cutting goes this sort of recomp was kind of a trial and error thing for me.

        My problem in general is that my body adapts pretty quickly to any kind of caloric deficit and responds with slowing down my metabolism. This does happen even with the setup I described above but it takes a bit longer. First time I went on it I made the mistake to do it for too long at a time (5 weeks) and I had a way too big gap between my caloric deficit and surplus which gave me a hard time on reload days causing me to “spill over” with the carbs and then crave them afterwards during the week.

        Eventually as I learned to calibrate my caloric intake vs. weight change, my body responded better as well. Still even with 4 days of caloric surplus my metabolism goes down, not by much, but at some point the effort doesn’t seem to give enough benefit. Two weeks never seem to be a problem but after the third week, in order to maintain the rate of fat loss, I find my self forced to reduce the average calories trough the week by a higher amount then it equals the weight change. I don’t feel any worse but I concluded that my metabolism is slowing down though so now I never do it for longer than 3 weeks and return to a steady slight caloric surplus at around 20f/50c/30p for a few weeks.

        It’s hard to objectivly measure my muscle gain during my carb-cycling but it’s deffinatelly there, eventhough it can’t compare with the results a steady supply of carbs at a continuous caloric suprlus.

        I know that this diet routine doesn’t sound like a great deal for some people but in terms of fat loss/muscle retention, carb cycling brought me the best results so far. Also a great benefit was that I developed a habit of being more careful about the quality of consumed carbs, which also helped me to avoid wild insulin spikes. I used to eat all kinds of processed crap before wondering why my gut engine wouldn’t get smaller. 😉

        I don’t think I’ll stay on this cycle trough the comming winter but I definatelly want to see how it compares to the same kind of a recomp/caloric intake but with something like 20f/50c/30p.

        I do believe that hormones have their role in fat loss but for sure not in such a huge way like it’s often believed today. Just like the issue with the thyroid I think it’s gladly used as a scapegoat for staying lazy. It still goes down to energy in – energy out.

        I never heard of Berkhan’s model but I’ll make sure to check it out, thanks!

        • Michael Matthews

          Definitely better to train on surplus days. Good call.

          Hmm I suspect that your training could be optimized. You shouldn’t be having any metabolic issues until you get to the 7-8% body fat range.

          What is your exercise schedule like? What type of lifting program are you following?

          You’re right, hormones don’t affect weight loss as much as some people believe.

      Thanks Max!

  • Andy

    Great article! i also just purchased your book. love how all the macros are already figured out for you, makes life that much easier. Cant wait to try some new recipes. I have a question about the 40/40/20. Do you keep it and your calorie intake the same on your rest days?

    • Michael Matthews

      Thanks Andy! I hope you like the recipes.

      I keep my cals the same when I’m cutting, and usually when I’m maintaining. (Kinda depends how big my Friday night cheat meal is, haha.) Sometimes I’ll drop 300-500 cals on my rest days when I’m maintaining.

      When I’m bulking, I like to drop cals to maintenance for my rest days.

  • Marissa Georgiou

    Hi Mike, I just read an article on tabatatimes.com about how women at resting burn glucose as opposed to men who tend to burn fat at rest. Therefore it suggested that manipulating carbs (carb cycling) occasionally could assist the body use fat stores. It did caution however that restricting calories too low would be counter effective. Would like to get your thoughts on this. Perhaps you could look into whether the articles comments on the metabolic differences between men and women are substantiated?

    • Michael Matthews

      I haven’t seen any research on the glucose vs. fat point, but I have seen research indicating that men simply oxidize fat easier than women (and thus can generally lose fat easier).

      That said, there’s no change as to how to lose the weight–moderate deficit, regular exercise, strength training a big bonus.

  • Samuel Sander

    Hey, first off – awesome blog, been soaking up the info for the past few hours 😀
    A few months ago I started with leangains and carb cycling. Decided to drop the carb cycling approach now and also add some randomness to IF – eg. eat breakfast on some days and do a longer fast than on others.

    Thing is though, now when I don’t carb cycle anymore – I should still stick to eating more calories on training days and less on rest days, right? How do you approach this (whether cutting/bulking/maintenance) – do you eat a set amount of calories each day or do you eat more on training days? (so calorie surplus/deficit would show on a weekly scale)

    • Michael Matthews

      Thanks Sam! Really appreciate it.

      Cool on what you’re doing. That’s totally fine.

      Yeah, a slight surplus on training days and a deficit on off days is a workable way of maintaining. I’m actually going to talk about it in depth in my next book, which will be out in January/Feb.

      The idea is your WEEKLY cals are at maintenance, but you don’t want your daily surplus so large that you have to eat next-to-nothing on your off days, haha.

      Keep in mind you don’t have to do this at all though. You can just eat TDEE every day and be fine too.

      • Samuel Sander

        Oki, so TDEE (including multiplier) or higher/lower calories depending on the nature of the day – both work. I reckon I’ll go with the latter on most days though..just personal preference.
        Thanks a lot! :))

        • Michael Matthews

          Yeah exactly. YW!

  • Jordan

    Do you have an article that goes into depth about all the different kinds of carbs? Mainly hi GI carbs vs low GI carbs? I know in BLS you mentione hi GI carbs are best eaten right after a workout, but other than that it’s better to stick with low GI. Is that the “definitive guide” version?

    Thanks Mike, love the info!

    • Michael Matthews

      No I don’t but this is on the list!

  • Jamal

    Mike, what is your opinion on people saying, skinny fats cannot be in surplus or deficit consistently or will gain fat/lose muscle? I’m skinny fat and until recently had been doing this… lift 4 times a week. On lifting days eat 300 cal below maintenance and on not lifting days eat 700 cal below maintenance. I’d follow the leangains guide where I’d do same protein every day but 70%/30% carbs/fat for the remaining calories on training days and 30%/70% carbs/fats on non-training days. All training done fasted so I would the body with carbs right after a training session, so i’d be in a short term surplus after I lifted weights. 2 of my rest days would include fasted cardio as well. This had worked well but I want to switch to the BLS program. Only problem is, my diet would have to change as the 5x a week program cannot allow for more than 2 rest days. So I’m thinking of switching to a consistent caloric deficit daily, same macros every day. I’m afraid that if that “consistently in a deficit” will lead to muscle loss for people with skinnyfat genetics theory is correct that I will lose a ton of muscle.

    • Michael Matthews

      Thanks Jamal! That’s bogus. Skinny fat is just a problem of body composition and you fix it the same. Some people need to eat more and some people less, but once you know your metabolism, you can just roll along smoothly.

      I don’t recommend alternating surpluses and deficits unless you’re an advanced weightlifter more or less happy with your physique and you’re just trying to stay lean and make slow, 3-5 pounds per year gains.

  • DJVege

    Only just read this page. I’ve carb cycled a few times in my life, only for about 3 months max in each straight run, and I’ve dropped fat/weight fairly well. However, you definitely you definitely feel LOW on the low/no days. Obviously, you don’t lift weights on those days (unless you’re an idiot), so I did cardio/stretching/rest on those days. I seemed to only lose a little muscle and a good deal of fat. I can see, reading your article, however, that the decrease is really just due to being in a weekly calorie deficit. Whether carb cycling is better at maintaining muscle during fat loss periods, I’m not sure, but I think I’d like to give a straight 40/40/20 a go to see the different.

    So, while I would definitely say Carb Cycling WORKS when done CORRECTLY, for the average human who wants to build muscle, lose weight, and not take steroids, 40/40/20 looks to be a much better fit. No low/no days where you feel crappy and irritated at work. :)

    Of course, sneaking in a week or 2 of carb cycling for photos is still viable. :)

    Thumbs up on the great article. I learned a lot.

    • Michael Matthews

      Thanks for the comment! Yeah, it works, it’s just not necessary, that’s all.

      Glad you liked the article. :)

  • Jay Abate

    Do you eat the same meals every day to assure your macros are correct?

    • Michael Matthews

      Yeah or if I want to change a meal, I make sure to look up the macros.

  • Danielle Martinson

    Great article! I had luck dropping a few pounds with carb restriction but boy was I weak and moody! I couldn’t do that for the long term so I gained it all back. Learned my lesson and now I follow the 40/40/20 which allows me to stick with it and have energy for my HIIT days as well as weight lifting days. Thanks for all the great information! :)

    • Michael Matthews

      Thanks Danielle! Haha yeah, low-carb dieting sucks. Nice on what you’re doing. Keep up the good work!

  • Jonas

    Do you know Martin berkhan or Anthony Mychal? they are both carb cycling and are insanely ripped as well…

    • Jonas

      anthony mychal suggests to eat 1 pound of meat per day, fattier on low carb, and lean meats on high carb, then much carbs on training days and much fat on rest days…
      i mean it seems to work ( look at the picture)
      i also like that idea of eating its just way more liberate!
      or could it just be done like this: “your everday diet” on training days, on rest days high fat? like 30 protein, 20 carb, 30 fat ( or what could you recommend?)

      how do you even maintain your diet when eating out or how can it be done?

      • Jonas

        thats anthony mychal

        • Michael Matthews

          Great physique for sure.

      • Michael Matthews

        That’s a sensible way to eat. i do something similar and talk about it in my next book, as “zig zagging” calories is most suitable for advanced lifters.

        Eating out sucks for dietary purposes. I just save it for cheat meals so I don’t have to think about it.

    • Michael Matthews

      Cycling calories can help you stay lean but a carb cycling routine that has you drastically lowering and raising carb intake just isn’t necessary.

      • Jonas

        would it work to eat a bit more fat on the off days and the recommended amount of carbs on training days( so no drastic lowering of carbs, but still enough carbs to fuel regeneration, basic movement etc, but bot as much as on training days, because not as much is needed) ..

        and how would this day look like in terms of macro ratio then?
        150 g protein still of course..

        but then? 100 grams fat, 200 grams carbs? how can i calculate that?
        the reason why i would probably enjoy this is because i like fatty stuff like yoghurt, milk, nuts oils all thr stuff but im very limited on training days, as in most of my protein sources theres already much fat with it..

        • Michael Matthews

          Yeah, that totally works. I will be talking about this in my next book and I break all the numbers down.

    Interesting. Carb cycling is the only thing that seems to work for me. I tried calorie defector using my fitness pal and weighing everything!! Excercise and weighing myself daily, my weight went up :(. I have hormonal problems, hypothyroid and have just gone on the contraceptive pill to balance my hormones (obviously I’m a girl). I’m assuming hormones play a big role in weight loss for people as well. We all have different levels which is why some weight loss programs work for some and not others. Just a theory

    • Michael Matthews

      It really depends how much you were eating previously and what your exercise routine was like. And you may have been running into water retention issues:


      Hormones don’t affect your ability to lose fat as much as people think. Yes, the lower your T levels the naturally heavier you will be, but hormones mess with water retention more.

  • Jason

    Hey mike good article like always. I have just recently started a carb cycling program and it sucks terribly lol.

    It’s from the book engineering the alpha by john romaniello.

    Your thoughts if you checked that out yourself.

    • Michael Matthews

      Thanks Jason! Haha I also hate low-carb dieting. Haven’t read the book….

  • Tommaso

    Another great article – certainly agree with the faddish euphoric element to IF/Carb-cycling and other “diets”

    That said, i’ve never followed a carb-cycle per se, though i do tend to reduce my carb intake fairly drastically when im cutting. I normally keep my carb intake at or around 1g per KG of bodyweight (for me that’s around 75) per day – the majority of which is taken pre and post workout, or if im using BCAAs for workouts, then post and either breakfast/dinner. All the while keeping protein high (~2.5-3g per KG of bodyweight), and fats moderate.

    Quantity control never seemed to work that well for me, whereas using low carb, and toying with some keto diet philosophies, i shed an appreciable amount of body fat, and didnt lose any noticeable muscle. My measurements stayed pretty much the same, and my lifts didnt seem to suffer too much, though that was while i was using the 8-12 rep range; not the BLS 4-6 range with much heavier weights.

    I think this time i may try to reduce my carb intake more gradually and see how i fare. Any thoughts?

    • Michael Matthews


      I also reduce my carbs when cutting simply because I have to reduce calories, but I never go below .8 grams per pound. Low-carb dieting sucks for training though. You lose quite a bit of strength.

      The bottom line is so long as your insulin response and sensitivity are good, you can get shredded eating plenty of carbs every day.

  • TheTallGuy

    Hi Mike, I just bought Bigger Leaner Stronger and am about halfway through, I am enjoying it. When I saw that you are actually answering questions here I got excited.
    Here’s my question. I’m a tall guy (6’7″, 245), medium build, about 20-30 lbs of fat I’d like to lose eventually, but would also like to put on 20lbs of muscle for a net affect of weighing about 235-245 lbs. If I were to choosing the bulking cycle first, I would need to start consuming around 3,660 calories a day. My current average is 2600-2800 and carbs on the low side. I have a hard time eating more than that, especially by adding complex carbs which I find very filling. But one easy way I know I could add another 500-700 calories without filling me up so much is Almonds. I love almonds, and I could add them as snacks and easily get to 3660. Only problem is that makes my Fat macros pretty high. Is there something magical about getting those extra calories from complex carbs? Or can I safely substitute for almonds?? Thanks!!

    • Michael Matthews

      Thanks so much!

      Cool on your stats and goal. I like it.

      It sounds like you should cut first. Here’s why:


      Let me know what you think!

      • TheTallGuy

        Thank you for the quick reply! I like the rule in that article helping to make the decision between bulking and cutting. You’re right, I am over 15% body fat (around 22-25% I think) so I should cut first. According to your formula that would put me at around 2600 cals per day.
        About my other question, when I do bulk, can I substitute almonds for brown rice to be able to get enough calories without stuffing myself? 3660 calories is just a lot to eat, I don’t care who you are, but due to my height, I need to find a way to do it. If I substitute some almonds, my macros would be at about 250g protein, 321 carb, 150 g fats. All healthy foods. Is that 150g fat going to harm me while bulking? Thanks!

        • Michael Matthews

          My pleasure! Cool let’s have you cut first.

          What I like to do is focus on eating a bunch of calorie-dense foods. Here are my favorites:

          Red meat

          Grains like brown rice and quinoa

          Oils like coconut oil and olive oil


          Whole-fat dairy

          Multi-grain pasta and bread

          Almonds and almond butter


          White and sweet potatoes

  • David Roberts

    Hey mate I’m 13 stone with 16bf how much protein fats and carbs would I need to do this carb backing loading to get lean, I train 4days a week, I understand that on non traing days you do less en 30grams of carbs but how much protein and fat would I need en and when I do train how much?

    • Michael Matthews

      You don’t have to carb cycle. Just do this:


  • Nikky

    When a person approaches carbs and fat cycling properly, she/he never trains on low/no crabs days (these days are rest days). Carbs and fat cycling works wonderfully! It works for both muscle gain and fat loss. I never reduce my calories. It doesn’t work for me. I do not understand how people can work out while reducing calories (energy level?). I cycle carbs and fat. I change my diet. I change my ratios. I am very happy with this approach because I can eat plenty of carbs and plenty of fat, and it works into my advantage. It also works well for females because girls burn more carbs than fat at rest!

    • Michael Matthews

      That doesn’t work if you’re training 5 days per week. And if you’re losing fat, you’re creating a calorie deficit. You just aren’t counting or tracking numbers, that’s all.

      • Nikky

        Correct. It does not work if you train 5 days per week, and that’s why I mentioned rest days. If a person trains 5 days per week and his body and CNS recover (and such person must lift exceptionally heavy if he needs to split body parts to train 5 days per week), he is either genetically very gifted or chemically enhanced. Training 5 days per week in most cases eventually leads to over training.

        I count my ratios precisely. Always. I just shared with you my experience. You made presumptions that do not exist.

        • Michael Matthews

          I work with hundreds of guys and gals of all ages training 5 days per week and they do great. The claims that 5 x per week = overtraining are bogus.

          Ah cool on the tracking. Then you know you’re creating a calorie deficit (restricting your calories)…

  • http://webbynode.com/ Felipe Coury

    Mike, I weigh 191lbs and I’m having around 200g protein daily to support muscular gains.

    Thing is I am still overweight and have a lot of fat to burn. I am following BLS’s routine and I am weekly beating my last week’s numbers, like clockwork.

    My current problem is that I am trying to stay at 1,800kcal por day and eating more carbs make that number go up a lot, considering I stick with 200g protein/day.

    My usual numbers are 40-50g fat, 100-200g carbs and 200-250g protein. Today, for instance I did 50g fat, 123g carbs and 209g protein, however the calories ratio is Carbs 27%, Fat 25% and Proteins 48%.

    I am noticing this is becoming a constant. Given that I am still losing weight, however now at a much slower pace (lost 58 pounds already, and am losing 0.5 to 1pound per week), should I change this ratio? How can I achieve that without affecting my protein intake? Or is my current ratio OK during this (eternal) cutting phase I’m on?


    • Michael Matthews

      The calories will determine overall weight loss but I would recommend keeping your macro intake more constant. You want the carbs to keep your training numbers up…

      • http://webbynode.com/ Felipe Coury

        Hi Mike!

        Thanks again for your reply.

        They are constant, just not 40% p / 40% c / 20% f. They are more like 50% p / 30% c / 20% f. Would that be a feasible goal if I stay at 1800kcal or should I really aim at 40/40/20?

        I think this was what I intended to ask.

        • Michael Matthews

          Ah okay. Protein doesn’t need to be that high but it’s not detrimental. Personally I would drop 5 – 10% pro and add to carbs.

  • Schyluer Jarman

    Mike great article. Im trying to learn everything I can about how to get as strong as possible while staying in a weight class for Olympic lifting.

And want to get to about 7-8% for my next competition while increasing muscle and strength BUT i have a weight class. What would you recommend? I lift 6 days a week. With two days being max effort on squats and 1 day max C&J.

    • Michael Matthews


      Hmm honestly by staying natural all you can do is diet and train correctly and see how your body responds. You sound like an experienced weightlifter so I highly doubt you’ll be able to go from 10 to 7% AND get stronger…

After trying several diet approaches, I found out that my body have a really good response with carb-cycling diets, even for bulking. My mass gains are bigger and leaner than with a high-carb diets. For me, it’s related to my overweight past and genetics (lot of people from my family has diabetes) that makes my body insulin resistence very high and work very well with carb cycling diets.

  • Ravi

    I think the issue is not around weight loss but fat loss. If any calorie deficient diet will result in weigh loss…. Are you saying an individual can go on a Twinkie and doughnut diet and lose weight as long as they are below they calorie maintenance level. I believe the reason behind the low carb diet is on the low carb days… The body relies on body fat stores for energy thus reducing fat. So low carb leads more to better body composition. All the diets may have lost the same weight but how did the individuals look? Was the body composition better in the low carb? That is the question.

    • Michael Matthews

      Yes, you can eat Twinkies and donuts every day and lose weight:


      But yes we care about body composition so we wouldn’t do that. And in fact low-carb dieting is going to result in a worse body comp than high-carb due to muscle loss. I talk more about this here:


  • David M. Day

    Hi Michael… Very very good write up. I’ve been looking for a good formula to follow and you have provided that perfectly. Is there a good “rule of thumb” formula for a “refeed day”? Or is a refeed not even need this particular system?

    • Michael Matthews

      Thanks! Generally a refeed is eating about 2-3g carb per pound of body weight and as little fat as possible.

  • bored@work

    Its good to see a post about diets that actually reference technical publications. Although, it seems as though diet is very person-specific. You referenced publications that show low carb diets as being equal in the long-term to traditional diets (although for small sample sizes). However, there are publications which show the exact opposite. One such publication concludes “ndividuals assigned to a [very low carb ketogenic diet] achieve a greater weight loss than those assigned to a [low fat diet] in the long term”:

    Nassib Bezerra Bueno, Ingrid Sofia Vieira de Melo, Suzana Lima de Oliveira and Terezinha da Rocha Ataide (2013). Very-low-carbohydrate ketogenic diet v. low-fat diet for long-term weight loss: a meta-analysis of randomised controlled trials.

    I think (and this is just personal opinion) that it really just comes down to the individual, and what works for their specific body.

    • Michael Matthews

      Thanks! I address this in a different article:


  • Kat

    Hi Michael,

    I just finished TLS a few days ago and really enjoyed it. I learned a lot about overall nutrition and strength. I have two questions for you. I’m currently 5’4, 130, 20.9% body fat and (like everybody else) I’d love to lose fat and gain muscle.

    1. Do I focus solely on HIIT cardio and calorie deficit to get down to 15% before I start strength training?

    2. According to the book calculations, I should be eating 1380 calories a day, at roughly 40/40/20. Does this include exercise? For example, if I burn 100 calories doing HIIT cardio, should I be eating those calories back?

    I apologize if you’ve answered these questions before, I tried to do some hunting for answers but didn’t come across any.


    • Kat

      I did a little more digging and came across your Healthy Meal Planning Tips post. I calculated 80% of my TDEE (with 1-3 hrs exercise per week) is 1322, which is less than the TLS calculation. Any advice on what to go by?

      And am I understanding correctly that if I go by 40/40/20 at 1322 cals per day, I don’t bother tracking calories burned per exercise and then try to eat them back?

      Thanks so much!

      • Michael Matthews

        Let’s start you at 1400 per day on 40/40/20 and see how your body responds.

        Yes you can’t eat any cals back.

    • Michael Matthews

      Thanks for reading my book and writing! I really appreciate it.

      Cool on your stats and goal.

      1. Let’s definitely start you with lifting. It will help preserve/build muscle.

      2. Yes that’s including exercise. Check this out for more info:

    Hi Mike.
    Awesome article, thanks :-)
    I’m a prof. badmintonplayer practicing 3-4 hours a day. Atm I’m in a 25% deficit and I’m getting lighter easily. However, I’ve read quite a few articles saying that a guy like me (around 9-8% bodyfat) should implement a “refeed” day once or twice a week, where I eat a bit over my maintenance to keep leptin and metabolism up?

    What is your thoughts?

    I’m currently eating 3500 kcals a day.

    Thanks a lot for helping out.


    • Michael Matthews


      Yes that’s a good idea. You should start with one per week and what you do is eat about 2 to 2.5 grams of carbs per pound of body weight with 1 g pro/lb and as little fat as possible.

      Enjoy! :)

      • http://viktoraxelsen.dj Viktor Axelsen

        Thanks Michael..
        However.. Would that get me to 4600 kcal which would be around my maintenance..


        • Michael Matthews

          You could try even more if you’d like… Some people go insanely high like 4 g carb/lb…

      • http://viktoraxelsen.dj Viktor Axelsen

        I weigh 187 pounds.. That would be around 467.5gr carb (1870 kcal) – 187gr protein (748kcal) I all ready eat around that amount of carbs at this weigh while being on 3500kcal..

        • Michael Matthews

          That’s right and the refeed isn’t so much about increasing cals as it’s about increasing CARBS…

  • Mukta Tolani

    Hey Mike!! Thank you for throwing light on this subject! I totally agree with your view. Also, I have noted that a “one size fits all” approach doesn’t work. So the conclusion you wrote makes it very simple.

    One thing I would like to know.. What kind of macro nutrient break up do you suggest your clients who are ovo-lacto vegetarian clients?? In my experience with a macro nutrient break up like :40 % CHO 40 % protein & 20% fats it becomes tough to meet protein requirements for such people (when they are doing proper weight training)
    I follow 60% CHO, 20% protein and 20% fats for these people. (I am a nutritionist)

      Thanks! I’m glad you liked the article.

      Very true and we generally try to get about .8 to 1 gram of pro per pound of body weight, about 30% of cals from fat, and the rest from carbs.

    Mike how would go about using a planned caloric intake instead of basing everything on grams per lb of BW. I have done many diets and it seems that I always stay the same no matter what my training protocol is. I have done IIFYM and Carb-Backloading and nothing. I am 6’5 230lbs. I am in pretty good shape except for the pudge around by stomach.I am very lean I mean veins in my thighs, chest, shoulder, and calves. I have always wanted to be more shredded (not stage shredded) but never could achieve it, could just be genetics. I want to give this carb-cycling a go but don’t know where to start. Right now i am going off of a 3000 cal diet with ~300 protein, ~230 carbs, and ~100g fat. I never know what calories to go by because I bust ass in the gym when I am in there. I was curious if you could point me in the right direction.

    • Michael Matthews

      Hey man! If you’re already fairly lean you’re just dealing with stubborn fat, and it can be a pain in the ass:

    Hey Mike,
    Been reading a lot of your posts because I have been feeling the need to change my diet and exercise routine. I workout about 6 times a week, i lift heavy at least 5 of those days and throw in one HIIT day on the 6th day if Im sore, etc. I also so some sort of HIIT after my lifting sessions. I feel that with the high intensity workouts I do that I should be eating more, but from years prior and trainers/nutritionists telling me things, I am kind of stuck in thinking that I am going to eat too many carbs and never have abs. But then I start to second guess myself and think that maybe I havent lost the stomach fat BECAUSE I am eating too few carbs and my calories are too low? What is your opinion on that? I know some people say that not eating enough will make you store fat as a reserve, etc…let me know what you think and how I should go about changing my diet to get “lean” Thanks!

    • Michael Matthews

    i lost weight with high carb diet when my body fat % were very high 32% until i reached 15% then my fat loss stopped no matter how hard i try i tried to reduce my calories even more but no fat loss at all i decided to give low carb diet a try n i lost fats on low carb diet n now i’m 8% body fats so high carb diet may be work for u but not work with everyone especially with high metabolic resistance n people have insulin resistivity our bodies not created equal

      • Deep

        Great article, thanks.

        In the above article you mention how everything looks numerically (adjustment of macros based on high, low or no carb day). What about the calories? Does that number stay constant or does a person’s caloric intake adjust. ie, more calories on high carb day and less calories on no carb day?

      • Deep

        Great article, thanks!

        You mention the macro breakdown in the above article (high carb, no carb etc) but what about total calories for the day? Does that number stay fixed or does it increase/decrease based on high carb, no carb days?

        • Michael Matthews


          It depends on the protocol you’re following, but most cycle calories as well.

    I found this very interesting. I’m curious what you would suggest for me. I’m currently at 18.5% body fat. So I have about 26# of fat on my body. I do have shredded 6 pack abs, very lean upper body and quads. Here is my struggle. I swear all 26# of fat is on my glutes, hamstring and inner thighs. I cannot lose it. I Lift heavy, do Hiit work out, no steady state cardio and I have built a lot of muscle. I’m searching for the correct diet to help me shed this fat and continue to gain muscle. I’m also almost 39 years old. I was thinking of carb cycling, but now I’m not so sure. That’s me on the right of big bird

      Also, I saw the titles of your books. I want to shed this fat but I don’t want to be thinner. I want to build muscle & drop to around 16% body fat. Would you still suggest the book for women?

      Wow you’re lean. Honestly if you get much leaner you’re going to enter the “problem” zone for women where your period can get irregular, your mood can become unstable, etc.

      I’ve seen women that can comfortably maintain 16-17% but I’ve seen just as many that simply can’t. It messes with their hormones too much.

    Hey Mike, All the studies you used compared low carb/ketogenic versus traditional dieting which we all know leads to a reduced metabolic rate. Did you actually find a study comparing CKD or carb cycling versus traditional dieting?

    • http://www.muscleforlife.com/ Michael Matthews

      Low-carb doesn’t necessarily impair metab but it just doesn’t offer anything special in the way of fat loss, which is the big pitch for carb cycling.

      My point with this article is you’re not doing anything particularly special by going really low-carb on certain days of the week.

    Great article! I’ve been trying to do some research on carb cycling, because the “theory” of it intrigues me, haha. Anyway, it is EXTREMELY difficult to find information with any true scientific backing. Most of it is someone trying to spread the gospel of how carb cycling is the key to being shredded.
    I thought the information you presented here was helpful, relevant, and most importantly- backed by data and research. Thank you.

    I do have a question, if you so happen to have the time to answer. What are your thoughts on lowering carbohydrate intake on rest days for someone who has a relatively high carb intake (190g day)? Would you recommend this? Thanks!

  • Barry and Tracy Burchill

    I read so many of your articles during my vacation and was very excited to find this on carb cycling. I was just about to try it and now am thinking otherwise. I am cardio queen turned weight lifter about 6 months ago. I am progressively lifting heavier. I have stopped the 16-18 reps and moved to 10 max lifting heavy 5 days per week with HIIT 2 days. My body is changing and I am at 20% body fat with a goal of 18. I am 36 with 3 kids and never dreamed I would see muscles like I do and my 5 year old would tell me “Mommy you have arm muscles like a boy”! I would love to hear what you think about how many calories I should be consuming. I have used many different calculators and coming from a background with anorexia and growing up with the magic 1200 calorie per day limit for women I have a hard time wrapping my head around 1900cal per day. I do use IIFYM and am at 1650 cal with a 40 carb, 35 protein and 25% fat split. I have a very hard time getting all my calories by the end of the day and carbs are always are hard one for me to fill. I am 140lbs and 5’5. Any help or suggestions would be so very appreciated. That little anorexia devil is always sitting on my shoulder saying I shouldn’t be eating that much but I know in order to grow and get lean I need to eat. I do eat 90% good quality foods and 10% junk. Thank you thank you thank you for all you do. I love every article you put out.

    Not a bad article. Although I believe you have failed to address is that more recent studies have shown that while macro breakdown doesn’t matter for overall weight loss, it certainly does for changes in body composition. The greatest changes in body fat have been seen in lower carb, moderate fat, higher protein diets. While this is not proof for the effectiveness of carb cycling, it does provide some scientific basis for it.

    • http://www.muscleforlife.com/ Michael Matthews

      You’re definitely right and I address this in many other articles I’ve written.

      For example:


      And the real problem with carb cycling is low-carb doesn’t help you lose fat faster:


  • Joseph

    Mike I see you are a pragmatist and I respect that. I think you could go a bit more in depth than just saying ” It is just a calorie/macro game, the end ”, though.
    1) Pennsylvania study talks about the effects of low carb. Carb cycling isn’t low carb. How is this study relevant ?
    2) Harvard study. In carb cycling nutrients are… cycled, not constant. Again, how is this study relevant ?
    3)Arizona study. Again, it is cycling, not specific,constant macros.
    4)OK I accept this one. However, what about extreme carb cycling, with keto-ish on the one end ( not just ”low” carb, but lower than 30g non-fiber carbs/day ) and massive carb ups on the other, as in carb-backloading ? Did you have any experience with it ?

    Hey mike , i realy like your articles but i think there is a misconception on this one . People with relative high body fat don’t need carb cycling , but as you get leaner your leptin hormone goes down , low leptin levels will slow down your metabolism wich will make it harder to burn fat. Leptin is carb sensitive so when you do a high carb day your leptin levels will replenish . This will signal the body that your are fueled or full . Your metabolic rate will increase as a result of this signal and your body will continue burning fat .This is just a short explanation why people do carb cycling .

    The studies you cite above don’t seem to involve people engaged in resistance training. It doesn’t make sense to me to base a position on these studies unless you qualify it first by being clear that it is for people who don’t lift. I make this point because resistance training is essential in getting your body to prioritize its metabolic pathways for either muscle building and or fat storage. In addition, your analysis seems to ignore to the effects of insulin level timing, ie, training with insulin levels low vs high, and cortisol levels low vs high. Still all in all a good read though, thanks.

    • http://www.muscleforlife.com/ Michael Matthews

      Being resistance trained doesn’t fundamentally alter how the metabolism works.

    Hi, this was a great article. I do have a question. I’ve read several articles on carb cycling and I see that there are different ways to go about it. Meaning some say alternate one high day then low day then on day 7 a cheat day. Some don’t have a moderate day. Also some say to count calories? If you keep your macros within the appropriate range. Isn’t that enough?

  • Sammi B

    Hi Michael…..I thought with carb cycling, the basis was: you eat high carbs on
    your weight training/most exercise intense days because your body needs it most on those days……then on your cardio/low/no exercise days you do low carbs since you may not utilize it as much. That way you lose weight especially since unused carbs are stored as fat in the body. Did I misunderstand this? I was planning on starting carb cycling just to try but based on your article it would seem pointless.

      and also I was told that you had to eat good quality carbs (i.e no junk)

    Hi Michael.
    Very interesting article. I tried classic diet and it worked for me fine. I’m looking into carb cycling diet but I’m not sure about the way you cycle your calories while on it.Would you increase calories with carbs increase or would you cut down on fats or protein to stay at the same calorie level (deficit of 20% in my case).
    My carb cycling would look like this:
    50,100,150,200,250,300 and 350 or more grams on 7th day.

Will this carbs cycling help me or it will just helps me to drop all my shape and don’t make me thinner but just skinnier ? I mean I workout and do HIIT beside so now what i want is just a little help to chase fat and make it leave my belly.

      What do you think?

  • Ryan G.

    I did weight lifting for 4 years while eating clean. I dropped to a good BF% (from 16% to around 12%) to be considered lean, but I wanted abs (I mean who DOESN’T want abs?) So I got myself on a carb cycling diet and, within 9 months dropped to 8.7% body fat and had a visible 6-pack. For me, carb cycling worked. I don’t do intermittent fasting for a good reason.

    Your liver and pancreas will produce enzymes to break down the triglycerides in adipose tissue into ketones and long-chain hydrocarbons. However, once you stop training, your body won’t filter/metabolize the byproducts (muscle fuel + “ashen” urine.) Instead, it will reform them into triglycerides and be restored as adipose tissue.

Now that I done, reverse dieted, I’ve started to Carb cycle to stay lean and build muscle to start prepping for fall. My question is- my numbers.. I used your number and the high/mod/day seem VERY high on the carbs.. Are those number male or female? My current weight is 113lb my high day was 243 and Mod was 170? Thanks for helping!!!

I’ve been training for 6 months now weight training and cardio and I’ve been eating healthy tracking my macros but I have seen NO progress.

      What do you think?

  • Liberal

    I have a respectfully disagree. Those studies and carb cycling are apples and oranges. Long term elimination or reduction in a macro puts the body into metabolic stress. Which produces platues for most especially when eating at a deficit. By cycling, the body never gets into metabolic damage, lowers cortisol, makes it easier to maintain sleep, and isn’t mentally difficult because you are just a few days around the corner to your next high carb day. Personally I’ve done 7 day cycles and 3 day cycles. Because of my workout schedule, 3 days worked better for me. Plus I eat an entire pizza after my workout on Saturday nights. 2 pennies worth.

    Hi Michael,
    You recommend a high carb day for an intense training day. What if I train first thing in the morning (4am)? Wouldn’t I want to have the carbs on the day prior as fuel for that workout the next day rather then eating high carbs afterwards?

    • http://www.muscleforlife.com/ Michael Matthews

    • http://www.muscleforlife.com/ Michael Matthews

      I don’t think it’s necessary unless you know that your body does better with overall lower levels of carb intake.

  • Dustin Johnson

    The problem with those studies is that they only choose overweight or obese people. It’s the same argument that people use against intermittent fasting in my book. People aren’t rats, and in reality, athletes aren’t people. Once you get to an athletic body composition the rules change a bit. I definitely see improved fat loss and muscle retention with carb cycling in my personal experiments with traditional and carb cycling diets (same starting and ending body fat 15-10). That’s N=1 anecdotal evidence though. Is it necessary, no, but I would say it’s optimizing everything you can.

    • http://www.muscleforlife.com/ Michael Matthews

      That’s true to a point but underlying mechanisms are what they are, regardless of health status.

      That said, I too have seen/worked with people that did better with lower carb intake/carb cycling when lean and wanting to get really lean, mainly because of poor insulin sensitivity.

      The majority of the thousands of people I’ve worked with don’t have that problem though and can get as lean as they want on a higher carb diet.

  • Vicky

    if I feel like my body doesn’t do well with carbs, is it a good idea to do reverse dieting? I have read your article on that, but I now am thinking I should try carb cycling since I have reached a plateau in my fat loss goal.
    also, on high carb days, does it matter if you spread the carbs throughout the day , or have one fairly large carb meal, and finish the rest off with little carb-included meals? Does that matter at all?
    I am trying to maintain the muscle I have gained while trying to lose fat. you mentioned that too much steady state cardio can make you lose that muscle. I have been doing rolling hills on the stairmaster a few times a week. is that more HIIT or LISS? I don’t want to do too much cardio if its going to make me lose muscle. I still also lift fairly heavy. not PR’s or 1 RM, but fatigued enough that 8-10 is difficult on the last few reps. that should be enough to maintain muscle, correct?

      You should reverse diet if you’re done cutting or if you’ve stopped losing weight after properly setting up a cutting meal plan and sticking to it.

      What matters are your daily totals for your carbs. The most important times to have them are pre and post-workout though.

      That cardio you’re doing is LISS. On how much cardio, take a look at this:

    Hey Michael,

    Hey Michael,

    I would love your opinion on my approach regarding where I should go next. I am a 23 year old fitness enthusiast, with an NASM CPT. I am very proud of my current physique, but am excited about how long the journey is ahead of me. I am always looking to get better. I got into lifting because of football in high school. I graduated with a good baseline knowledge of training at least in the sense that I would hit 2-3 workouts a week where I would go all out and hit Flat Barbell Bench, Cleans, Squats, Deadlift often, and then 3-4 exercises for each body part. I made crazy newbie gains (a term I know you like). I went from a skinny soccer player/runner’s body with great abs to a very strong solid, pretty lean early college kid. In high school those newbie gains came with eating tons of healthy and tons of unhealthy foods. Didn’t seem to matter. In college I continued to make gains, but learned the heard way that I needed to eat cleaner. I got bigger but definitely put on a few % body fat. I stayed this way until the summer before my senior year of college where I cleaned up my diet and really started putting more effort into my training. Instead of lifting for maintenance I went in there with an attitude. I ate clean and got a solid physique with a six back, solid legs, solid arms, solid chest. Abs to write home about nothing else all that amazing. Good not great. Then I was put on to Greg Plitt by a good friend. I treated his site like the bible. I was absolutely shocked when he died almost exactly a year after he changed everything for me. RIP. His videos changed the game for me. I realized I was a hard gainer and started mimicking his lifting style and really becoming a student of the game. I put on size and got leaner leaving me graduating college at a crazy low body fat and a vascular composition with solid size. Throughout this past year I realized that as great as it was to be a low body fat, I wasn’t holding the size and strength I used to have underneath the fat. I think Plitt’s workouts are more tailored to a cutting style rather than size and strength. Your hit failure and you hit it hard with Plitt. I will say I started lifting, yes lifting, everyday. Chest, Back, Shoulders, Arms, Legs, start over. Yes I take off days, but I don’t plan them. A day of traveling or an occasional busy weekend day maybe. They come just often enough that I don’t ever know an off day is coming nor plan for it. I like it that way because the rest days and days of the week I hit body parts is always changing. Monday isn’t always chest and my off days aren’t always after legs. I started hitting biceps and hamstrings with back while they also get hit on arms and legs respectively. So Im lifting a lot and its worked pretty well for me. I can hit 225 on flat bench for 10, I can deadlift houses, I got 315 on squat for a solid 9 the other day, form all there. I bulked to get here though. For the first time in a long time I decided to attempted a bulk. I was crazy low body fat and was 6’2″ 195, but people always thought I weighed less. Now I am around 208 and have put on great size and am still leanish, but not as much as before. Where do I go now Michael? Do I carb cycle? Should I just clean up my diet which currently includes whole milk and quite a few egg yolks. Im eating a ton. Like a bodybuilder and my bulk is almost becoming a cut because my increased muscle mass has caught up with what my previous calorie surplus. I love getting bigger and stronger and its still fun because I am a naturally lean person with athletic genes. Where do I go from here? I always want to get better keep that in mind. I work hard, I meal prep, I want the knowledge I need to be my literal best. Thanks so much for reading I really hope you respond and I would be open to buying a meal plan happily if you feel you have some insight.

      Hey man!

      IMO calorie cycling is perfect for someone in your position:


      But not necessarily carb cycling.

      And this is going to be very applicable to you:


      And this as well:


      Give them a read and LMK what you think.

    Thanks for posting this! I wasn’t sure if I wanted to carb cycle or just stick to my macros ( 189.5 carb, 108 protein, 54 fat 27/34 fiber ) it’s a whole new experience for me since I would love to compete on the wbff league before I turn 31. I feel I’m making slow improvements ( which im happy about. It’s all about patience ) but when it comes to diet and cardio I feel I lose all my gains, which it already happened before , now I’m kinda just going with the flow, yes I eat healthy, but I have cheats at least 3 times per week, it’s hard for me to find that balance, I think I should consider sticking to my macros at least for 8 weeks to see how my body reacts to it, I lift heavy, ( not as heavy as you ) but I do take my training seriously, I do go ham on leg days, back and arms, I usually don’t do much chest, and no cardio, for the reason I stated before, I end up enjoing morning runs on the beach that become marathons lol and all the hard work at the gym goes away. What can you suggest for my fitness goals and my training?

      Glad you liked it!

      Yeah sticking to your diet is very important, especially as you get leaner.

    Hey Mike, I’m a pretty big fan of yours and I love your podcasts.

    I played college football for two seasons, took two seasons off and now I am trying to play for one more. I have lost a good amount of muscle over the time off. I was at one point about 214 lbs with 13-14% bf. I am now around 190 with about 15% bf. Learning about muscle regain has greatly excited me as I am trying to get all of my strength/size back in the next three months. I have experience with heavy compound lifting. I am planning to train 6x a week, fasted, taking BCAA’s and green tea extract before my workouts. (I want to be as anabolic as possible) I will also include 4-6 run sessions a week (one day of 110’s and one day of 20yd bursts.) At this point I am going to divide my splits as follows:

    Day 1: heavy back squat or front squat, heavy deadlift, pullups, curls, abs, short sprints

    Day 2: light power snatch, heavy shoulder press, heavy bench press, weighted dips, light shoulder fly, 110 yd strides

    My weeks will alternate so that week one will include three day 1s and two day 2s and week 2 will include three day 2s and two day 1s.

    I am aiming to consume 3300 calories, my BMR is about 2900 with exercise.

    What do you think?

      Thanks Max!

      Cool on your plans. I like it all around. Just have to make sure you manage your volume properly…

    hey Mike! love all your stuff! right now i am around 126 lbs. given the moderate carb day, that would put me well under the calories I’ve been consuming (1650-1700- those calculations of macros add to under 1400) especially for my high activity level. How would i tweak it?

    • http://www.muscleforlife.com/ Michael Matthews


      Sorry but I don’t understand your question…

      • Melina Olivia DiPaola

        Sorry if my Q was kinda vague- using the #’s in the article I think my calorie count was too low.
        What would you suggest as a high carb day % and low carb day % for someone wanting to shred? I’m 125 lbs and workout regularly, about 1650-1700 cals a day. Just not sure what to set as macros for the carb cycling . Would ❤️your input. Also I love forge! If my preworkout has 10 cals w bcaas, does that mess up the fast?


        • http://www.muscleforlife.com/ Michael Matthews

          Oh okay. Honestly I wouldn’t bother with carb cycling if I were you. Given your weight I doubt you have insulin sensitivity issues…

          • Melina Olivia DiPaola

            Thx!!! Just tryin to get better shredded! Not nec. A weight issue

          • http://www.muscleforlife.com/ Michael Matthews

            NP! I understand. :) I recommend just setting up a cutting meal plan.

    Thanks for the read. I’m hoping this will help me in reaching my goal of 190. I started at 290 almost a year ago and I’m 22 years old, currently 5′ 9 at 221 pounds with no movement on the scale. I’ve consumed about 1800 calories every day with cheat meals on Thursday. I’m very interested in carb cycling but I’m confused as to how I should start. On my high days I would consume 300 grams and 150 on lows. How should I schedule these days during the week? Should I focus more on my macros or calorie intake? Is 300 grams a fair carb intake for a high day?

      Great job on the weight loss.

      I wouldn’t bother with carb cycling if I were you.
