About Calorie Calculator
Uses the Mifflin–St Jeor equation to estimate your basal metabolic rate, then multiplies it by an activity factor to estimate the calories you burn per day. Eating about 500 kcal less or more per day roughly shifts weight by 0.5 kg per week.
Important considerations
An estimate for healthy adults only; real needs vary with body composition, health and medication. Not medical advice — talk to a doctor or dietitian before major diet changes.
