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

Using the Mifflin-St Jeor equation with your exact inputs — age 40, weight 80 kg (176 lbs), average woman's height (162.6 cm) — the resting metabolic rate is 1455 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 1746 kcal (sedentary) to 2510 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.
