Calculate your Basal Metabolic Rate (BMR) to understand how many calories your body burns at rest using the Mifflin-St Jeor equation.
BMR (Basal Metabolic Rate) is calculated using the Mifflin-St Jeor equation: for men, BMR = 10×weight(kg) + 6.25×height(cm) − 5×age − 5. A 30-year-old, 180 cm, 80 kg male has a BMR of about 1,780 calories.
