How Many Calories Does a 50-Year-Old 180 lb Man Need?

Using the Mifflin-St Jeor equation with your exact inputs — age 50, weight 180 lbs (81.6 kg), average man's height (175.3 cm) — the resting metabolic rate is 1667 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 2001 kcal (sedentary) to 2876 kcal (very active).

Age 50 note: In your fifties, protein needs stay high (1.2–1.6g/kg) while calorie needs drop. Prioritizing protein and resistance training prevents the muscle loss that accelerates aging.

Calorie Targets by Goal

Goal	Daily Calories	Expected Result
🔵 Aggressive weight loss	1542 kcal	~1.5 lbs/week
📉 Weight loss	1792 kcal	~1 lb/week
✅ Maintenance	2292 kcal	Weight stable
💪 Lean bulk	2592 kcal	~0.5 lbs/week
🏋️ Aggressive bulk	2792 kcal	~1 lb/week

Calorie Needs by Activity Level

Activity Level	Description	Daily Calories
Sedentary	Desk job, minimal movement	2001 kcal
Lightly active	1–3 workouts/week	2292 kcal
Moderately active	3–5 workouts/week	2584 kcal
Very active	Hard training 6–7 days/week	2876 kcal

BMI at 180 lbs

At 180 lbs (81.6 kg) and average height for a man (175.3 cm), your BMI is 26.6 — Overweight ⚠️. BMI is a useful screening tool but doesn't measure body composition. Waist circumference and muscle mass provide additional context.

Macronutrient Split at 2292 kcal

Macro	% of Calories	Grams/day	Calories
Protein	30%	172 g	688 kcal
Carbohydrates	40%	229 g	916 kcal
Fat	30%	76 g	684 kcal

For weight loss at 1792 kcal/day, increase protein to 35% (157 g/day) to preserve muscle during the deficit. At age 50, protein becomes increasingly important for maintaining metabolic rate.
