How many calories should a 25-year-old woman of 55kg eat per day?

BMR (Basal Metabolic Rate) is the calories your body needs at complete rest to maintain basic functions like breathing and circulation. TDEE (Total Daily Energy Expenditure) multiplies BMR by an activity factor. At sedentary, TDEE ≈ 1.2× BMR; at very active, TDEE ≈ 1.725× BMR. Your TDEE is 1756 kcal vs BMR of 1277 kcal.
