What is a healthy calorie deficit?

A common range is 300–750 kcal per day, aiming for about 0.25–0.75 kg (0.5–1.5 lb) per week. Avoid dropping below safe calorie floors.

How fast will I lose weight?

Roughly 7700 kcal is often used as an estimate for 1 kg of fat (about 3500 kcal per pound). Real loss varies week to week; treat projections as rough.
