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

Using the Mifflin-St Jeor equation with your exact inputs — age 45, weight 200 lbs (90.7 kg), average man's height (175.3 cm) — the resting metabolic rate is 1783 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 2139 kcal (sedentary) to 3075 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	2751 kcal	~0.5 lbs/week
🏋️ Aggressive bulk	2951 kcal	~1 lb/week

Calorie Needs by Activity Level

Activity Level	Description	Daily Calories
Sedentary	Desk job, minimal movement	2139 kcal
Lightly active	1–3 workouts/week	2451 kcal
Moderately active	3–5 workouts/week	2763 kcal
Very active	Hard training 6–7 days/week	3075 kcal

BMI at 200 lbs

At 200 lbs (90.7 kg) and average height for a man (175.3 cm), your BMI is 29.5 — Overweight ⚠️. BMI is a useful screening tool but doesn't measure body composition. Waist circumference and muscle mass provide additional context.

Macronutrient Split at 2451 kcal

Macro	% of Calories	Grams/day	Calories
Protein	30%	184 g	736 kcal
Carbohydrates	40%	245 g	980 kcal
Fat	30%	82 g	738 kcal

For weight loss at 1951 kcal/day, increase protein to 35% (171 g/day) to preserve muscle during the deficit. At age 45, protein becomes increasingly important for maintaining metabolic rate.
