How Many Calories Does a 30-Year-Old 100 kg Man Need?

Using the Mifflin-St Jeor equation with your exact inputs — age 30, weight 100 kg (220 lbs), average man's height (175.3 cm) — the resting metabolic rate is 1951 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 2341 kcal (sedentary) to 3365 kcal (very active).

Age 30 note: Late twenties — metabolism is still strong. Prioritize protein and resistance training now to build a metabolic foundation that serves you for decades.
