How Many Calories Does a 35-Year-Old 55 kg Man Need?

Using the Mifflin-St Jeor equation with your exact inputs — age 35, weight 55 kg (121 lbs), average man's height (175.3 cm) — the resting metabolic rate is 1476 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 1771 kcal (sedentary) to 2545 kcal (very active).

Age 35 note: After 30, metabolic rate begins declining ~1–2% per decade, driven by gradual muscle loss. Resistance training 2–3×/week largely offsets this.
