How Many Calories Does a 25-Year-Old 100 kg Woman Need?

Using the Mifflin-St Jeor equation with your exact inputs — age 25, weight 100 kg (220 lbs), average woman's height (162.6 cm) — the resting metabolic rate is 1730 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 2076 kcal (sedentary) to 2985 kcal (very active).

Age 25 note: In your mid-twenties, metabolism is near its peak. This is an ideal time to build muscle mass, which raises your resting BMR permanently.
