The Mifflin-St Jeor BMR Equation
The Mifflin-St Jeor formula is considered the clinical standard for estimating human resting metabolism:
- Men: $$\text{BMR} = 10 \times \text{weight (kg)} + 6.25 \times \text{height (cm)} - 5 \times \text{age (yrs)} + 5$$
- Women: $$\text{BMR} = 10 \times \text{weight (kg)} + 6.25 \times \text{height (cm)} - 5 \times \text{age (yrs)} - 161$$
- TDEE: $$\text{TDEE} = \text{BMR} \times \text{Activity Multiplier}$$
