Protein = weight × 2.0 g. Fat = TDEE × 0.25 / 9. Carbs = (TDEE − protein×4 − fat×9) / 4.

Preguntas Frecuentes

Why 2 g of protein per kg?
It covers active adults and athletes. Sedentary adults can use 1.2–1.6 g/kg; large bodybuilders sometimes go up to 2.4 g/kg during cuts.
Can I adjust the fat share?
Yes. 25% is a moderate default; 30–35% fits low-carb plans, 20% fits higher-carb endurance plans. Keep protein fixed and trade off the rest between fat and carbs.
