How Many Calories Does a 40-Year-Old 80 kg Man Need?

Using the Mifflin-St Jeor equation with your exact inputs — age 40, weight 80 kg (176 lbs), average man's height (175.3 cm) — the resting metabolic rate is 1701 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 2041 kcal (sedentary) to 2934 kcal (very active).

Age 40 note: Your mid-thirties are a critical window: muscle loss accelerates if untrained. Maintaining 1.6–2g protein/kg and consistent training keeps metabolism high.
