How Many Calories Does a 25-Year-Old 150 lb Man Need?

Using the Mifflin-St Jeor equation with your exact inputs — age 25, weight 150 lbs (68.0 kg), average man's height (175.3 cm) — the resting metabolic rate is 1656 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 1987 kcal (sedentary) to 2857 kcal (very active).

Age 25 note: In your mid-twenties, metabolism is near its peak. This is an ideal time to build muscle mass, which raises your resting BMR permanently.

✅ Maintenance	2277 kcal	Weight stable
💪 Lean bulk	2577 kcal	~0.5 lbs/week
🏋️ Aggressive bulk	2777 kcal	~1 lb/week

Calorie Needs by Activity Level

Activity Level	Description	Daily Calories
Sedentary	Desk job, minimal movement	1987 kcal
Lightly active	1–3 workouts/week	2277 kcal
Moderately active	3–5 workouts/week	2567 kcal
Very active	Hard training 6–7 days/week	2857 kcal

BMI at 150 lbs

At 150 lbs (68.0 kg) and average height for a man (175.3 cm), your BMI is 22.1 — Healthy weight ✅. BMI is a useful screening tool but doesn't measure body composition. Waist circumference and muscle mass provide additional context.

Macronutrient Split at 2277 kcal

Macro	% of Calories	Grams/day	Calories
Protein	30%	171 g	684 kcal
Carbohydrates	40%	228 g	912 kcal
Fat	30%	76 g	684 kcal

For weight loss at 1777 kcal/day, increase protein to 35% (155 g/day) to preserve muscle during the deficit. At age 25, protein becomes increasingly important for maintaining metabolic rate.
