ⓘ Sex, weight & height set your metabolic baseline (BMR) and daily targets — encrypted, never shared.
How we calculate this
Daily calorie target
1. BMR (calories at rest) via the Mifflin-St Jeor equation: 10·kg + 6.25·cm − 5·age (+5 male / −161 female).
2. × 1.2 (resting + basic daily living) → your baseline budget.
3. Adjusted for your goal: −300 to lose weight, +300 to build muscle.
4. Exercise you log is added back to your daily budget on Today — so the baseline stays low and we never double-count activity.
No weight/height entered? We use a 70 kg / 170 cm average so you still get a starting target — add yours for a personalized number.

It starts with your body, then adjusts for what you're aiming at. Nothing here is fixed — you can change it whenever you like.
