How Many Calories Does a 50-Year-Old 80 kg Woman Need?

Using the Mifflin-St Jeor equation with your exact inputs — age 50, weight 80 kg (176 lbs), average woman's height (162.6 cm) — the resting metabolic rate is 1405 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 1686 kcal (sedentary) to 2424 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.
