About
AI Eat Tracker is a single-file offline calorie tracker. Your data never leaves this browser.
The science: Daily target is calculated using the Mifflin–St Jeor BMR equation × your activity multiplier, then adjusted by your goal. ~7,700 kcal deficit ≈ 1 kg of fat loss.
Tips: Weigh yourself at the same time daily (morning, after bathroom). Log meals right when you eat. A small surplus here and there is fine — consistency beats perfection.
