How Many Calories Does a 45-Year-Old 190 lb Woman Need?

Using the Mifflin-St Jeor equation with your exact inputs — age 45, weight 190 lbs (86.2 kg), average woman's height (162.6 cm) — the resting metabolic rate is 1492 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 1790 kcal (sedentary) to 2574 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.

🏋️ Aggressive bulk	2552 kcal	~1 lb/week

Calorie Needs by Activity Level

Activity Level	Description	Daily Calories
Sedentary	Desk job, minimal movement	1790 kcal

Macro	% of Calories	Grams/day	Calories
Protein	30%	154 g	616 kcal
Carbohydrates	40%	205 g	820 kcal
Fat	30%	68 g	612 kcal

For weight loss at 1552 kcal/day, increase protein to 35% (136 g/day) to preserve muscle during the deficit. At age 45, protein becomes increasingly important for maintaining metabolic rate.
