How Many Calories Does a 25-Year-Old 180 lb Woman Need?

Using the Mifflin-St Jeor equation with your exact inputs — age 25, weight 180 lbs (81.6 kg), average woman's height (162.6 cm) — the resting metabolic rate is 1547 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 1856 kcal (sedentary) to 2668 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%	160 g	640 kcal
Carbohydrates	40%	213 g	852 kcal
Fat	30%	71 g	639 kcal

For weight loss at 1627 kcal/day, increase protein to 35% (142 g/day) to preserve muscle during the deficit. At age 25, protein becomes increasingly important for maintaining metabolic rate.
