How it works

TDEE = BMR × an activity multiplier. Eating at your TDEE maintains your weight; eating below it leads to weight loss over time.

Formula

TDEE = BMR × activity factor (1.2 – 1.9)

Example

A BMR of 1,750 with light activity (1.375) gives a TDEE of about 2,400 calories.

Assumptions & limitations

  • Based on population formulas that may not fit athletes, pregnancy, children or medical conditions.
