Find your Basal Metabolic Rate: the calories your body burns at complete rest.
We use the Mifflin-St Jeor equation. Men: 10 × weight (kg) + 6.25 × height (cm) − 5 × age + 5. Women: 10 × weight (kg) + 6.25 × height (cm) − 5 × age − 161. The revised Harris-Benedict equation is shown for comparison. Your BMR makes up about 60–70% of the calories you burn each day.
