How Many Calories Does a 45-Year-Old 210 lb Woman Need?

Using the Mifflin-St Jeor equation with your exact inputs — age 45, weight 210 lbs (95.3 kg), average woman's height (162.6 cm) — the resting metabolic rate is 1583 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 1899 kcal (sedentary) to 2730 kcal (very active).

Age 45 note: After 40, hormonal changes further reduce metabolic rate. Sleep, stress management and strength training become increasingly important for body composition.

Macro	% of Calories	Grams/day	Calories
Protein	30%	163 g	652 kcal
Carbohydrates	40%	218 g	872 kcal
Fat	30%	73 g	657 kcal

For weight loss at 1676 kcal/day, increase protein to 35% (147 g/day) to preserve muscle during the deficit. At age 45, protein becomes increasingly important for maintaining metabolic rate.
