How Many Calories Does a 40-Year-Old 90 kg Woman Need?

Using the Mifflin-St Jeor equation with your exact inputs — age 40, weight 90 kg (198 lbs), average woman's height (162.6 cm) — the resting metabolic rate is 1555 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 1866 kcal (sedentary) to 2683 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.
