How Many Calories Does a 30-Year-Old 80 kg Woman Need?

Using the Mifflin-St Jeor equation with your exact inputs — age 30, weight 80 kg (176 lbs), average woman's height (162.6 cm) — the resting metabolic rate is 1505 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 1806 kcal (sedentary) to 2597 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.
