How Many Calories Does a 50-Year-Old 100 kg Man Need?

Using the Mifflin-St Jeor equation with your exact inputs — age 50, weight 100 kg (220 lbs), average man's height (175.3 cm) — the resting metabolic rate is 1851 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 2221 kcal (sedentary) to 3192 kcal (very active).

Age 50 note: In your fifties, protein needs stay high (1.2–1.6g/kg) while calorie needs drop. Prioritizing protein and resistance training prevents the muscle loss that accelerates aging.
