How Many Calories Does a 50-Year-Old 90 kg Woman Need?

Using the Mifflin-St Jeor equation with your exact inputs — age 50, weight 90 kg (198 lbs), average woman's height (162.6 cm) — the resting metabolic rate is 1505 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 1806 kcal (sedentary) to 2597 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.
