About BMR

BMR (Basal Metabolic Rate) is the number of calories your body needs to maintain basic physiological functions at rest. TDEE (Total Daily Energy Expenditure) includes your activity level.

BMR Formula (Mifflin-St Jeor):

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

Factors Affecting BMR:

Age (decreases with age)
Gender (men typically higher)
Weight and height
Muscle mass
Genetics
Hormones
