How Many Calories Does a 45-Year-Old 200 lb Woman Need?

Using the Mifflin-St Jeor equation with your exact inputs — age 45, weight 200 lbs (90.7 kg), average woman's height (162.6 cm) — the resting metabolic rate is 1537 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 1845 kcal (sedentary) to 2652 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.

💪 Lean bulk	2414 kcal	~0.5 lbs/week
🏋️ Aggressive bulk	2614 kcal	~1 lb/week

Calorie Needs by Activity Level

Activity Level	Description	Daily Calories
Sedentary	Desk job, minimal movement	1845 kcal
Lightly active	1–3 workouts/week	2114 kcal

BMI at 200 lbs

At 200 lbs (90.7 kg) and average height for a woman (162.6 cm), your BMI is 34.3 — Obese 🔴. BMI is a useful screening tool but doesn't measure body composition. Waist circumference and muscle mass provide additional context.

Macro	% of Calories	Grams/day	Calories
Protein	30%	159 g	636 kcal
Carbohydrates	40%	211 g	844 kcal
Fat	30%	70 g	630 kcal

For weight loss at 1614 kcal/day, increase protein to 35% (141 g/day) to preserve muscle during the deficit. At age 45, protein becomes increasingly important for maintaining metabolic rate.
