The Math

We calculate your daily calorie needs using the Mifflin-St Jeor equation, which estimates how many calories your body burns at rest (BMR) and adjusts for your activity level (TDEE).

Daily Calories

We adjust your TDEE by 15% down for weight loss, 0% for maintenance, or 10% up for weight gain.

Macro Profiles

These determine how daily calories are distributed across protein, fat, and carbs:

Profile Protein Fat Carbs
Balanced 25% 30% 45%
High-protein 35% 25% 45%
Low-carb 30% 45% 25%
Ketogenic 20% 70% 10%
Low-fat 30% 20% 50%

Fiber is estimated at 14 grams per 1,000 calories regardless of profile.
