Frequently asked questions
What does TDEE mean?
TDEE is Total Daily Energy Expenditure — the calories your body burns in a day including basal metabolism, daily activity, and exercise. Eating at TDEE maintains your current weight.
Why does this use the Mifflin-St Jeor equation?
Mifflin-St Jeor (1990) is the most accurate BMR formula for the general adult population according to peer-reviewed comparisons. It is the standard used by registered dietitians.
Why 500 calories for one pound per week?
One pound of body fat stores roughly 3,500 calories. A 500-calorie daily deficit times 7 days equals 3,500, producing approximately one pound of fat loss per week. Actual results vary by individual.
