How this is calculated

Your calorie target is your TDEE adjusted for the goal: cut subtracts 500 kcal, bulk adds 500 kcal, maintain leaves it as-is. The diet preference splits those calories into protein, carbs, and fat.

Splits (protein / carbs / fat): balanced 30/40/30, high-protein 40/35/25, low-carb 35/25/40, keto 25/5/70

Grams: protein and carbs 4 kcal/g, fat 9 kcal/g, rounded to the nearest gram

If the split would put protein below 1.6 g per kg of bodyweight, protein is raised to that floor and carbs and fat are reduced proportionally so the calorie total holds.
