Set your calories and preferences, then click Calculate to see your macro split
Macronutrients (protein, carbohydrates, and fat) provide the calories your body needs. Protein and carbs provide 4 calories per gram, while fat provides 9 calories per gram. The optimal macro split varies by goal: higher protein supports muscle building and satiety during fat loss, while adequate carbohydrates fuel intense exercise. Keto diets shift the body to use fat as its primary fuel source through ketosis. Research suggests that total calorie intake matters most for weight change, but macro ratios significantly affect body composition and performance.
