Formula & Mathematical Explanation

\displaystyle \text{BMR}_{\text{Male}} = 10W + 6.25H - 5A + 5, \quad \text{BMR}_{\text{Female}} = 10W + 6.25H - 5A - 161

Basal Metabolic Rate (BMR) is calculated using the Mifflin-St Jeor formula. Total Daily Energy Expenditure (TDEE) multiplies BMR by an activity factor to estimate daily maintenance energy needs.
