How Many Calories Does a 40-Year-Old 200 lb Woman Need?

Using the Mifflin-St Jeor equation with your exact inputs — age 40, weight 200 lbs (90.7 kg), average woman's height (162.6 cm) — the resting metabolic rate is 1562 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 1875 kcal (sedentary) to 2695 kcal (very active).

Age 40 note: Your mid-thirties are a critical window: muscle loss accelerates if untrained. Maintaining 1.6–2g protein/kg and consistent training keeps metabolism high.

Calorie Targets by Goal

Goal	Daily Calories	Expected Result
🔵 Aggressive weight loss	1398 kcal	~1.5 lbs/week
📉 Weight loss	1648 kcal	~1 lb/week
✅ Maintenance	2148 kcal	Weight stable
💪 Lean bulk	2448 kcal	~0.5 lbs/week
🏋️ Aggressive bulk	2648 kcal	~1 lb/week

Calorie Needs by Activity Level

Activity Level	Description	Daily Calories
Sedentary	Desk job, minimal movement	1875 kcal
Lightly active	1–3 workouts/week	2148 kcal
Moderately active	3–5 workouts/week	2422 kcal
Very active	Hard training 6–7 days/week	2695 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.

Macronutrient Split at 2148 kcal

Macro	% of Calories	Grams/day	Calories
Protein	30%	161 g	644 kcal
Carbohydrates	40%	215 g	860 kcal
Fat	30%	72 g	648 kcal

For weight loss at 1648 kcal/day, increase protein to 35% (144 g/day) to preserve muscle during the deficit. At age 40, protein becomes increasingly important for maintaining metabolic rate.
