How Many Calories Does a 45-Year-Old 190 lb Man Need?

Using the Mifflin-St Jeor equation with your exact inputs — age 45, weight 190 lbs (86.2 kg), average man's height (175.3 cm) — the resting metabolic rate is 1737 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 2085 kcal (sedentary) to 2997 kcal (very active).

Age 45 note: After 40, hormonal changes further reduce metabolic rate. Sleep, stress management and strength training become increasingly important for body composition.

Macro	% of Calories	Grams/day	Calories
Protein	30%	179 g	716 kcal
Carbohydrates	40%	239 g	956 kcal
Fat	30%	80 g	720 kcal

For weight loss at 1889 kcal/day, increase protein to 35% (165 g/day) to preserve muscle during the deficit. At age 45, protein becomes increasingly important for maintaining metabolic rate.
