Carbohydrates for Gaining Muscle Mass

What’s the role of carbohydrates in gaining muscle mass and how should I include them in my diet?

Carbohydrates are a hugely important macronutrient in the diet of athletes, and many researchers have associated a low consumption of carbs with worse results in terms of gaining muscle mass.

Why are carbohydrates important for muscle mass?

Carbohydrates have an important indirect relation with muscle mass, as they are not a plastic nutrient, that’s to say, they’re not intended for the creation of new contractive muscle tissue, but they do have an effect on it.

They are different from proteins and fat, and affect body weight differently.


We accumulate glycogen in the muscles, which are nothing more than large branched polymers of thousands of units of bound glucose.

This glycogen acts as an energy store, and our muscles are releasing and using glucose from the branches to contract which training, which is important for performance.

A low carb diet has been observed to decrease the time to fatigue and negatively affects the muscle’s ability to produce force. (Leveritt and Abernethy, 1999).

The mechanism thought to underlie the proposal that very low-carb diets may adversely affect the body’s ability to produce force is thought to be mediated by altered calcium metabolism during muscle contraction, reducing nerve excitability. (Ørtenblad et al., 2011).

Carbohydrate fatigue

A decrease in strength conditions the weight we can lift in the gym and will make it harder for us to improve.

It’s important to consume at least a small amount of carbohydrates to maintain glycogen concentrations above the cut-off threshold from which this effect occurs.

Aproximately 1g per kg of body weight is recommended to provide energy in the form of calories, necessary for gaining muscle.

Which carbohydrates help gain muscle mass?

All carbohydrates are good options for contributing to this positive effect on muscle tissue.

Even so, it is preferable that the vast majority of the carbohydrates we consume are based on glucose, such as cereal starches, as fructose is a sugar capable of filling the glycogen deposits of the liver more efficiently than glucose (Blom et al., 1987).

Glucose and Fructose

And vice versa, glucose more efficiently replenishes muscle glycogen (Conlee et al., 1987).

Based on these recommendations, the best sources of carbohydrates for muscle mass are cereals, legumes, tubers, dextrins (maltodextrin, cyclodextrin, amylopectin) and dextrose.

Foods with carbohydrates

As mentioned above, there are many foods rich in carbohydrates that can be useful for athletes.

Except in cases of high energy demand, such as:

  • Ultra-endurance athletes.
  • CrossFit® athletes with a high level of sports performance.
  • Bodybuilders who perform double sessions, or similar.

It’s best to avoid the use of foods rich in simple carbohydrates or sugars, such as honey, sugary cereals and other ultra-processed foods as its easy to ingest an excess of calories using these products: by its palatability and its low ability to induce satiety.

  • Oats.
  • Potatoes.
  • Lentils.
  • Beans.
  • Maltodextin.
  • Amylopectin.
  • Cyclodextrin.
  • Bread.
  • Fruit.

Sources should be chosen according to the user’s own preferences and the adaptability to their diet to avoid accumulating too much fat.

Proteins or carbohydrates for gaining muscle mass?

Protein is the nutrient most directly related to the development of the body’s muscle tissue, more than fat and carbohydrates.

About a fifth of our muscle fibres are made up of protein, and increasing your intake, along with a proper workout and rest, contributes to an increase in muscle mass:

According to data from the review by Morton et al. (2018), the amount of protein you should consume through the diet to optimise the body’s muscle mass gain is:

1.6 to 2.2 grams of protein per kilogram of body weight.

Conditions for building muscle

The main exogenous factors that determine muscle mass gain, without excessive accumulation of fat are:

  • Training with loads.
  • A high-protein diet.

In addition to other factors such as following a diet high in calories and energy, sufficient rest, in terms of quantity and quality, and dietary supplementation with products such as creatine monohydrate should help.
