Gaining muscle is not quite as easy as going to the gym and lifting weights. That is just one part of the equation. In reality, gaining muscle requires two main things: a stimulus for growth and the energy to grow tissue.Outside of significant hormonal changes (e.g., puberty or steroid use), the primary catalyst for growth comes from resistance training. The energy to grow tissue comes from the food we consume in the form of calories. You can bulk up in a clean way just by following strategic nutritional planning.
Whether you are a Certified Nutrition Coach, Sports Nutrition Coach, Bodybuilder, or an enthusiast looking to optimize your muscle growth - this blog will show you the nutritional requirements and necessary food for gaining muscle.
Let's dive in!
How Many Calories Do You Need To Gain Muscle?
The question is, how much energy (or calories) do you need to gain muscle? There are many nuanced answers to the quandary, but here are the main things to know about this topic.
First, the optimal way to gain muscle tissue is through being in a relative calorie surplus, meaning that you must consume more calories than you expend.
Second, there appears to be a limit on how quickly people can gain muscle tissue. That means at some point, too much of a calorie surplus adds fat tissue and not any more muscle tissue; too few calories and the rate of muscle gain can be too slow to be useful.
The optimal calorie surplus appears to be between ~350-500 kcal per day (~1500-2000 kJ per day) (1).
You can track your calories and macros with the NASM Weight Loss Calculator, if you want a convenient way to do so.
How Much Protein and Carbohydrates Do You Need To Gain Muscle?
The optimal protein intake for gaining muscle appears to be between 1.6 and 2.2 g/kg, based on the most up-to-date scientific literature (2). The lower end of this range, ~1.6 g/kg, appears to be the point of "saturation" for most of the population and should be considered the target number for most people for optimal protein intake for gaining muscle. This translates to around 0.7-0.8 g/lb of body weight per day.
Carbohydrates also appear to be critical for maximizing muscle growth. Lack of carbohydrates in the diet has been shown to impair muscle growth in some populations, and the current guidelines for optimizing muscle growth are 4-7 g/kg per day (3). This translates to 1.8-3.2 g/lb of body weight per day.

Constructing Recipes for Gaining Muscle
Recipes for gaining muscle should have three primary goals:
1) the correct calorie amount
2) adequate protein intake
3) sufficient carbohydrates intake
In addition to these three primary goals, recipes for gaining muscle should also include a robust micronutrient (e.g., vitamin and mineral) profile.
Here are some recipes you can use to help meet the three primary goals that meals must meet to help gain muscle as well as providing solid micronutrition.
