How the Calculation Works

Multiplies BMR by activity coefficient to calculate Total Daily Energy Expenditure (TDEE).

Formula: TDEE = BMR × Activity Multiplier

Practical Worked Example

Given Inputs: 72kg, 175cm, Moderate activity

Calculated Output: Maintenance: ~2,580 kcal/day

  1. Calculate BMR and multiply by 1.55.
Pro Tip: Adjust your caloric intake based on your goals, but ensure you don't drop below your BMR for sustained periods without medical supervision.
