FAQ

How is the timeline estimated?

Uses the rough rule ~7700 kcal ≈ 1 kg of body mass change, so days ≈ (kg × 7700) ÷ daily deficit. Deficit is capped to a broad plausible range; very long timelines are rejected. Educational heuristic only.

Does the decimal separator matter?

This calculator uses plain decimal numbers. If a result looks wrong, check whether you used a comma instead of a dot (or vice versa) where the field expects one.
