How Many Calories Does a 25-Year-Old 180 lb Man Need?

Using the Mifflin-St Jeor equation with your exact inputs — age 25, weight 180 lbs (81.6 kg), average man's height (175.3 cm) — the resting metabolic rate is 1792 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 2151 kcal (sedentary) to 3091 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.

💪 Lean bulk	2764 kcal	~0.5 lbs/week
🏋️ Aggressive bulk	2964 kcal	~1 lb/week

Calorie Needs by Activity Level

Activity Level	Description	Daily Calories
Sedentary	Desk job, minimal movement	2151 kcal
Lightly active	1–3 workouts/week	2464 kcal

Very active	Hard training 6–7 days/week	3091 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 2464 kcal

Macro	% of Calories	Grams/day	Calories
Protein	30%	185 g	740 kcal
Carbohydrates	40%	246 g	984 kcal
Fat	30%	82 g	738 kcal

For weight loss at 1964 kcal/day, increase protein to 35% (172 g/day) to preserve muscle during the deficit. At age 25, protein becomes increasingly important for maintaining metabolic rate.
