How Many Calories Does a 30-Year-Old 180 lb Man Need?

Using the Mifflin-St Jeor equation with your exact inputs — age 30, weight 180 lbs (81.6 kg), average man's height (175.3 cm) — the resting metabolic rate is 1767 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 2121 kcal (sedentary) to 3048 kcal (very active).

Age 30 note: Late twenties — metabolism is still strong. Prioritize protein and resistance training now to build a metabolic foundation that serves you for decades.

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 2430 kcal

Macro	% of Calories	Grams/day	Calories
Protein	30%	182 g	728 kcal
Carbohydrates	40%	243 g	972 kcal
Fat	30%	81 g	729 kcal

For weight loss at 1930 kcal/day, increase protein to 35% (169 g/day) to preserve muscle during the deficit. At age 30, protein becomes increasingly important for maintaining metabolic rate.
