How Many Calories Does a 45-Year-Old 220 lb Man Need?

Using the Mifflin-St Jeor equation with your exact inputs — age 45, weight 220 lbs (99.8 kg), average man's height (175.3 cm) — the resting metabolic rate is 1874 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 2248 kcal (sedentary) to 3232 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	3076 kcal	~1 lb/week

Calorie Needs by Activity Level

Activity Level	Description	Daily Calories
Sedentary	Desk job, minimal movement	2248 kcal

BMI at 220 lbs

At 220 lbs (99.8 kg) and average height for a man (175.3 cm), your BMI is 32.5 — 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%	193 g	772 kcal
Carbohydrates	40%	258 g	1032 kcal
Fat	30%	86 g	774 kcal

For weight loss at 2076 kcal/day, increase protein to 35% (182 g/day) to preserve muscle during the deficit. At age 45, protein becomes increasingly important for maintaining metabolic rate.
