Why do you need carbohydrates? This article explains how you can integrate carbohydrates into your diet to help build more muscle faster.

If you ask any bodybuilder to tell you about protein’s role in muscle building you’ll get an in-depth response about the way muscle builds, hypotrophy, anabolic rates and more! But what about if you asked the same bodybuilder about the role of carbohydrates and building muscle? I doubt you’d get a very lengthy response.

Carbohydrates are often overlooked when planning a muscle building diet. This is because a lot of people are not aware of the importance of carbohydrates and the role they play in muscle development. The truth is what type of carbohydrates you eat, when you eat them and how much you eat can have a great effect on the muscle building process.

If you want to optimize your diet for muscle gain and fat loss it’s important to know how to integrate carbohydrates into your diet. There’s nothing complex about it, you just have to follow a few simple rules.


  1. Eat complex carbohydrates
    Complex carbohydrates are found in whole foods like brown rice, potatoes, whole grain cereal and oatmeal. Complex carbohydrates should make up the bulk of your daily calorie intake because they form muscle glycogen, the long lasting fuel that your body needs to train hard. Complex carbohydrates are slow burning which means you get longer lasting energy. They also help keep your blood sugar levels constant, this reduces fat storage and fatigue and promotes the release of insulin. Insulin is the body’s natural anabolic hormone and is essential for muscle development.
  2. Eat carbohydrates directly after training
    When you train hard you reduce your blood sugar level considerably. Eating carbohydrates straight after a training session provides your body with an insulin spike. This insulin spike puts your body into an anabolic (muscle building) state. If you do not get the right nutrients after training it’s possible that your body could enter a catabolic (muscle breakdown) state. This is why post workout nutrition is so important.
  3. Eat small amounts of carbohydrates more often
    Eating smaller servings of carbohydrates more often helps keep a steady flow of insulin into the body. If you eat large amounts of carbohydrates in one sitting your body is much more likely to store them as fat. Eating to much is one sitting is unnecessary; your body doesn’t need that much nutrients at one time.
  4. Eat high fiber carbohydrates
    This goes hand-in-hand with point number 1 because most sources of complex carbohydrates are rich sources of fiber. Fiber helps to build muscle by making muscle tissue absorb amino acids faster and more efficiently.
  5. Avoid fruits
    This may sound insane because we all know that fruit is high in vitamins, low in calories and very good for general health and wellbeing. But, fruit contains fructose which is a very simple sugar. The body converts fructose into glycogen which is used as a building block for fat tissue.
  6. Have carbohydrates and protein in the same meal
    When you mix protein and carbohydrates together in the same meal you minimize the chance of the carbohydrates being stored as fat. Protein is harder for the body to process, so it increases your metabolism. Also, carbohydrates help transport the nutrients from protein to the muscle cells which aids in muscle growth.

Follow these rules, and you can use carbohydrates to your advantage to build more muscle faster. If you find you’re gaining too much fat then you should cut out carbs after 7pm. Unless you have a fast metabolism, eating carbs late at night is generally not a good idea. Your body does not need the energy while you’re sleeping so it’s likely to store the carbs as fat.

Another point worth mentioning here is meal sizes. Like I stated in point 3, you should eat small meals more often. Have you ever felt really tired after eating? Then you’ve eaten too much. Your body has to use a lot of energy to process the food which leaves you feeling tired and energy-less. This style of eating will also decrease your metabolic rate. To keep your metabolism high you need to constantly stimulate it with small meals every 3 hours or so.

So the main points you need to remember here are; eat good complex carbohydrates, eat small amounts more often, always have a good serving of complex carbohydrates about 1 hour before your workout (for energy) and straight after your meal (for insulin spike) and if you are gaining excess fat stop eating carbohydrates after 7pm.

Posted on: Fri, 09/20/2013 - 22:28

got a question couldn't your body used stored fat cells as an energy source since they are mostly made from eating to many carbs? not talk about post work out I know your body needs carbs and protein then, but not sure if it needs as much as most mass builders have on the market normally 2:1 ratio of carbs to protein (at least the mass builders I've seen). but in later meals hours after your work out couldn't you decrease the number of carbs taken in increase the amount of healthy fats and get gains in mass while burning fat for fuel? I'm thinking like 40% fat calories 20% carb calories 40% protein calories in later meals

Hi steve...Great Article...but Im confused now....I had a hard workout and diet too loosing weight...now I start working body building to gain muscles but Im worry about it.....I worry about that I gain fat ..im confused about the size and the time of my food ....thanks

I wonder how fruits influence the body if we consume them before the bed with casein (like berries, banana, etc.) Does glycogen/sugar affect the body negatively at this time?

I weigh about 225. I need to lose 16 pounds of fat and I want to replace it with muscle. When should I stop eating complex carbs in the day and will the fat shed as I continue to lift? I am lifting to build muscle and I am taking protien and creatine. I eat every 3 hours and I am wondering if I am missing anything. I see some gains but my weight is staying the same.

Posted on: Tue, 02/05/2013 - 09:53

What a load of nonsense. Suggest those of you who think that fruit spikes their blood sugar, eat a piece a mango, papaya, apple, etc and monitor your blood sugar. You will see that what this guy says is pure nonsense. But go right on eating your breads and pastas...and see how that works for ya!

In the last columns , Instead of "straight after your **workout** (for insulin spike)", it was written as ,"straight after your **meal** (for insulin spike)"
Please correct this. Thankyou

If u workout /eat right 90% of the time. You'll be fine.. Trust me u won't get fat from eating to many apples or bananas... Just try to mix on all kinds of fruits and veggies and protein.. Just eat like a caveman with the acception of whole grains eat those too.. Just don't eat trans fats and don't over eat candy and chips they all have really low nurturent compared to the calories..

Posted on: Tue, 09/25/2012 - 10:20

In the first number you say that glucagon is muscle building and good to help get through workouts, but in the last number you say fructose is converted into glucagon and that that's bad. I'm just confused.

What? Fruit isn't high on the gi scale. Unless ur eating pineapple or tropical fruits in that nature. Ie. Apples is in the 40s on the gi scale, oatmeal (complex carb 55) research before u write and throw a bunch of people into frenzy. Fruit makes u fat! I have used fruit all the way up to the day of a show.

BroScience at its best,
Some idiot read a theory of fructose metabolic pathways back in 1985 and broscience'd up an article about how fruit was bad. This theory has perpetuated ever since and its plainly wrong. Every single study -> see pubmed -> regarding fruit, body fat, body composition (actually regarding any carb type simple or complex) shows that there is absolutely 0 difference between any of the carb types on overall body composition.

Unfortunately this broscience rumor will persist to the end of time....

Posted on: Tue, 06/05/2012 - 06:15

What an absolute load of rubbish! This article has obviously been written by someone with absolutely no knowledge on gaining muscle and maintaining a healthy body. Fruit is essential to everyone's diet and mixing proteins with carbs is the perfect way to get fat, not to put on good quality muscle mass: Proteins need an acidic environment in the stomach to be properly digested whereas carbs and starchy foods need an alkaline environment - Mix the two together and they neutralize each other causing the food to remain in the body partially undigested.

Posted on: Sat, 04/28/2012 - 19:37

You had me until the fruit comment.

Not all fruits are fructose based; the dreaded banana has a greater proportion of glucose to fructose and is an excellent post workout choice. The glycogen comment was hilarious. The reason fruits are a poor choice as your only carbohydrate source in the diet is because -fructose- cannot be stored in the muscle; only the liver. Fructose turns to fat only if your liver is full. and you don't consume fiber with it: fruit is full of fiber.

Glucose can fill the liver and then the muscle and not turn into fat until both are full.

Fruit also cleans your colon better than any fiber supplement you can think of. Eat three apples a day for a clean break every morning. If you're afraid of the tiny amount of fructose in apples you have a problem. Calories are king in terms of fat loss. I think the largest apple out there has about 100 calories?

There are severe contradictions in this article which I can imagine to be very confusing to a newcomer in the world of nutrition. To discus the role of glycogen in the body alone would need it's own page at the very least. There is an element of truth to the whole fruit deal in that fructose is by far the worst form of sugar to put in your body and over time will strain your system regardless of weather there is a calorie surplus or not. The article says the body uses glycogen as a building block for fat? This is highly misleading as the Glycolysis energy system is constantly ongoing. Also the body is always given the option to use glycogen for energy to which it is converted to ATP, if it is not needed or used it is then (and only then) converted to fat. In terms of carbs with protein, yes everyone is different and people have there nutritional beliefs (which are often based on myth and Chinese whispers) but the body does use protein much more efficiently when taken with a SMALL amount of carbs as an insulin spike is produced. That is a nutritional fact, if there ever was one.
My advice to any one starting out in this field would be to keep it simple, get your research from credible science and nutritional books or websites (not blogs) and build your knowledge up slowly. You can then make your own informed decisions as you go along. Don't ask other gym members, P.TS or read blogs, Case and point above.

Posted on: Sun, 09/06/2015 - 19:53


Thanks for the thoughts. Are there any particular websites you recommend for the proper muscle building / fat losing info? I am new to the work out world and want to know the correct information about losing fat while gaining muscle.


Posted on: Tue, 04/10/2012 - 15:17

So is glycogen good or bad? First the writer says it is needed to build muscle fiber, but then he contradicts himself and says it turns to fat. Which is it?

Posted on: Sat, 03/31/2012 - 23:48

Wow there is so much wrong with this article. Fruit and sugar turning into fat? Explain to me how if I am burning 2500 calories in a day, and eat 2500, yet I have sugar in there, that I will gain mass. You need a calorie surplus to gain mass, so I don't see how this is possible. Calories in vs. calories out. I eat ice cream every day and still stay lean, you mad?

Posted on: Sun, 04/08/2012 - 17:08

You do realize there are different body types and what may work for you may not for others. Some people are genetically predisposed to gain muscle mass with poor diets. I think this article is pretty accurate for the most part and should provide results for most people who will give his advice a try. Fructose is sugar, sugar is a simple carb, simple carbs that are not converted into energy are stored as fat.

Posted on: Tue, 03/13/2012 - 15:41

This article is so devoid of science it is scary. The insulin and fruit commentary is just absurd. People will be wise to avoid these "tips" and search out real scientific explanations.

Insulin is the primary hormone responsible for adipose accumulation, excessive insulin levels can lead to weight loss, inflammation and more importantly the stunting of human growth hormone secretion. Avoiding fruit is nonsense period. Most fruit are loaded with fiber which results in most fruit having a much lower glycemic load than potatoes, rice and pasta. This means that fruit turning into fat is about as likely as the author having any scientific training.

Mixing carb and protein helps to minimize carbs being stored as fat??!!!!! WTH?
CArbs get digested in an alkaline state. Protein in an acidic state. So when you combine either the carb or the protein doesnt get digested well, ie fat accumulation.
The greatest trainer ever, the Iron Guru, Vince Gironda, was strongly opposed to mixing carbs and proteins.

Strongly disagree with this article.
Shakes head in disbelief....

You want to focus on two things to maximize results:

1) Pushing yourself in the gym. Using good form, always push yourself on every set. When you can perform the recommended number of reps for a set, add weight.

2) Eat to maximize muscle gains. Here are some articles that can help:

Your snack between lunch and dinner should contain at least 30 grams of protein. You also don't appear to be eating very many carbs at all, and probably not enough calories.

What time of day do you lift?

This was a great article I enjoyed the read but nO Fruit? oh crap! So much for my blueberry & greek yogurt smoothies in the mornings! WHy can't I have a fruit with something like 20 carbs and eat it with a protein with say... 40 carbs? Or drink a whey protein shake & a banana, or eat some grapes with nuts. Couldn't I do that? Have simple carbs with proteins. That way I can still enjoy the fruit and keep my blood sugar levels stable.

Posted on: Mon, 08/27/2012 - 18:19

Think about it this way:
your body digests the sugar in fruit really fast. Once digested, now it's in your blood stream. Your blood now has tons of sugar to use for energy, however, the protein you say you eat takes time to digest. The digestion of protein will use the new acquired energy in your blood but not instantly. If all the sugar in your blood is not being used the body decides to store it for later use aka fat. Look up the relationship of hyperglycemia and Insulin and how spiking blood sugar can lead to fat storage.

For overall health, yes fruit is good for you but only when taken at the appropriate times where your body needs all that energy (ex: Morning, just after strenuous exercise).

If you need more info as to why fruits preferably avoided, look up these words and understand them: Blood Sugar, Hyperglycemia, and Insulin.

I thought this was a fairly well written article until I read the part about eating fruits. Seriously? Avoid fruits? I admit. I had a good laugh out of that one

Posted on: Thu, 07/28/2011 - 06:33

Fruit is bad guys when doing serious weight training . When you get older and have trained for 30 years you will agree but while your young knock yourself out . To much fruit is full of sugar and makes it harder on your body to digest all the proteins and fats . Gas is what builds up and I would advise all serious weight lifters to only eat berries in the morning on an empty stomach . Large portions of fruit will hold your digestion back as will large portions of any simple sugars and most fruit is not low GI . Some are but the bulk of fruits and fruit juices are a no no...

Posted on: Wed, 04/06/2011 - 18:18

It doesnt make any sense about the fruit. Everything is broken down in to sugar for energy that your body consumes. No matter what kind of carb it is. Simple or Complex. Fruit is good to eat about 45 minutes before a work out along with a protein shake. Its easier to digest then a complex carb and its giving you a lot of energy to lift.

Posted on: Tue, 02/08/2011 - 01:36

Most fruits are low GI and very good source of fibre. I disagree with the fruit comment because they are an excellent source of nutrition for all forms of sport including weight lifting. Plus, the body can't digest all the fructose from the fruit, hence they seem low in calories and why if u eat to much fruit then you will know because you will feel very sick and be on the toilet constantly.

Posted on: Fri, 06/03/2011 - 11:49

I agree. To be honest, when I read the part about fruit consumption, I was stunned. I think that advice like that is irresponsible. Fruit is an important part of a healthy lifestyle. Isn't that what we want?
I think that the purpose of fitness/bodybuilding/strength training should first of all be, to stay healthy, AND second, to build a strong, muscular body, not the other way around.
