What is BMR?

Basal Metabolic Rate (BMR) is calories needed for basic functions like breathing and circulation at rest. It accounts for 60-75% of daily calorie burn.

Mifflin-St Jeor Formula

Men: (10 × weight) + (6.25 × height) - (5 × age) + 5
Women: (10 × weight) + (6.25 × height) - (5 × age) - 161

TDEE (Total Daily Energy Expenditure)

TDEE = BMR × Activity Factor. This is your total daily calorie burn.
