How Many Calories Does a 45-Year-Old 75 kg Man Need?

Using the Mifflin-St Jeor equation with your exact inputs — age 45, weight 75 kg (165 lbs), average man's height (175.3 cm) — the resting metabolic rate is 1626 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 1951 kcal (sedentary) to 2804 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.
