Mifflin-St Jeor Equation (Most Accurate)
Men: BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age) + 5
Women: BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age) − 161
How to Use Your BMR

- Eat below TDEE to lose weight; above TDEE to gain weight
- BMR decreases with age — recalculate annually
