How Many Calories Does a 45-Year-Old 130 lb Woman Need?

Using the Mifflin-St Jeor equation with your exact inputs — age 45, weight 130 lbs (59.0 kg), average woman's height (162.6 cm) — the resting metabolic rate is 1220 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 1464 kcal (sedentary) to 2104 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	2177 kcal	~1 lb/week

Calorie Needs by Activity Level

Activity Level	Description	Daily Calories
Sedentary	Desk job, minimal movement	1464 kcal

Macro	% of Calories	Grams/day	Calories
Protein	30%	126 g	504 kcal
Carbohydrates	40%	168 g	672 kcal
Fat	30%	56 g	504 kcal

For weight loss at 1177 kcal/day, increase protein to 35% (103 g/day) to preserve muscle during the deficit. At age 45, protein becomes increasingly important for maintaining metabolic rate.
