How Many Calories Does a 25-Year-Old 140 lb Man Need?

Using the Mifflin-St Jeor equation with your exact inputs — age 25, weight 140 lbs (63.5 kg), average man's height (175.3 cm) — the resting metabolic rate is 1611 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 1933 kcal (sedentary) to 2778 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	2215 kcal	Weight stable
💪 Lean bulk	2515 kcal	~0.5 lbs/week
🏋️ Aggressive bulk	2715 kcal	~1 lb/week

Calorie Needs by Activity Level

Activity Level	Description	Daily Calories
Sedentary	Desk job, minimal movement	1933 kcal

Very active	Hard training 6–7 days/week	2778 kcal

BMI at 140 lbs

At 140 lbs (63.5 kg) and average height for a man (175.3 cm), your BMI is 20.7 — 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 2215 kcal

Macro	% of Calories	Grams/day	Calories
Protein	30%	166 g	664 kcal
Carbohydrates	40%	222 g	888 kcal
Fat	30%	74 g	666 kcal

For weight loss at 1715 kcal/day, increase protein to 35% (150 g/day) to preserve muscle during the deficit. At age 25, protein becomes increasingly important for maintaining metabolic rate.
