How Basal Metabolic Rate Is Calculated

BMR is the number of calories your body needs at complete rest to maintain basic life functions like breathing, circulation, and cell production.

Mifflin-St Jeor:
Men: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age + 5
Women: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age - 161
