How is this calculated?

This tool uses the common estimate that ~3,500 kcal ≈ 1 lb (or ~7,700 kcal ≈ 1 kg) of body weight. Weekly loss is estimated from your daily calorie deficit. Real-world results can vary.

For a more realistic timeline, the tool shows a range because day-to-day adherence and metabolic adaptation can change outcomes.
