A calorie deficit means consuming fewer calories than your body burns (TDEE), so that it uses fat reserves for energy. A larger deficit speeds up fat loss but is harder to sustain in the long term.
Not everyone can sustain the same pace. A sustainable deficit is easier to follow consistently, while a rapid one may be suitable for short periods if you already have experience with dietary control. Comparing the three options helps you make a conscious choice, not a random one.
The actual weight loss pace depends on metabolism, activity, sleep, and consistency — factors that a calculator cannot measure exactly. Therefore, the values above are an estimated starting point, not a guarantee of a specific number of kilograms within a certain timeframe.
