How Many Calories Does a 40-Year-Old 220 lb Woman Need?

Using the Mifflin-St Jeor equation with your exact inputs — age 40, weight 220 lbs (99.8 kg), average woman's height (162.6 cm) — the resting metabolic rate is 1653 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 1984 kcal (sedentary) to 2852 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	1523 kcal	~1.5 lbs/week
📉 Weight loss	1773 kcal	~1 lb/week
✅ Maintenance	2273 kcal	Weight stable
💪 Lean bulk	2573 kcal	~0.5 lbs/week
🏋️ Aggressive bulk	2773 kcal	~1 lb/week

Calorie Needs by Activity Level

Activity Level	Description	Daily Calories
Sedentary	Desk job, minimal movement	1984 kcal
Lightly active	1–3 workouts/week	2273 kcal
Moderately active	3–5 workouts/week	2562 kcal
Very active	Hard training 6–7 days/week	2852 kcal

BMI at 220 lbs

At 220 lbs (99.8 kg) and average height for a woman (162.6 cm), your BMI is 37.7 — Obese 🔴. BMI is a useful screening tool but doesn't measure body composition. Waist circumference and muscle mass provide additional context.

Macronutrient Split at 2273 kcal

Macro	% of Calories	Grams/day	Calories
Protein	30%	170 g	680 kcal
Carbohydrates	40%	227 g	908 kcal
Fat	30%	76 g	684 kcal

For weight loss at 1773 kcal/day, increase protein to 35% (155 g/day) to preserve muscle during the deficit. At age 40, protein becomes increasingly important for maintaining metabolic rate.
