How Many Calories Does a 45-Year-Old 70 kg Man Need?

Using the Mifflin-St Jeor equation with your exact inputs — age 45, weight 70 kg (154 lbs), average man's height (175.3 cm) — the resting metabolic rate is 1576 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 1891 kcal (sedentary) to 2718 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.
