Endomorphs have a larger bone structure with higher amounts of total body mass and fat mass. Football lineman and powerlifters are frequently endomorphs. They tend to be naturally less active. Where the ectomorphs tend to burn off excess calories with near constant movement, excess calories in endomorphs do not seem to cause that same increase in expenditure. This means that excess calories are more likely to be stored as fat. This profile leads to a greater propensity for energy storage, including both lean mass and fat mass. This can also mean a lower carbohydrate tolerance.
Endomorphs typically do best on a higher fat and protein intake with carbohydrate intake being controlled and properly timed (e.g., after exercise). So that’s what we recommend: more fat and protein, less carbohydrate.
A nutrient distribution for this body type might be around 25% carbs, 35% protein, and 40% fat. Again, no math gymnastics. Just think higher fats and protein, lower carbs.
