NomiHow it is calculated
Protein is set from body weight, fat uses a share of target energy, and carbohydrates receive the remaining calories. Protein and carbs use 4 kcal per gram; fat uses 9 kcal per gram.
Worked example
Example: at 2,000 kcal, 120 g protein and 60 g fat account for 1,020 kcal. The remaining 980 kcal equals about 245 g carbohydrate.
