How the calculator works

It estimates the calories your body burns at rest with the Mifflin-St Jeor equation, then multiplies that by your activity level. Then it sets your goal:

Protein is set at 0.8 grams per pound of body weight (1.8 grams per kilogram), fats at 25% of your calories, and carbs fill the rest. Protein and carbs have 4 calories per gram; fats have 9.
