How Many Calories Does a 25-Year-Old 140 lb Woman Need?

Using the Mifflin-St Jeor equation with your exact inputs — age 25, weight 140 lbs (63.5 kg), average woman's height (162.6 cm) — the resting metabolic rate is 1365 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 1638 kcal (sedentary) to 2355 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.

Macro	% of Calories	Grams/day	Calories
Protein	30%	141 g	564 kcal
Carbohydrates	40%	188 g	752 kcal
Fat	30%	63 g	567 kcal

For weight loss at 1377 kcal/day, increase protein to 35% (120 g/day) to preserve muscle during the deficit. At age 25, protein becomes increasingly important for maintaining metabolic rate.
