Plan Your Weight Loss Journey Realistically

Sustainable weight loss is not about crash diets — it is about finding a calorie deficit you can maintain consistently. Our calculator shows you exactly how long it will take to reach your goal at different rates of loss, so you can choose a pace that fits your lifestyle. A slower rate (0.25-0.5 kg/week) is easier to sustain and preserves more muscle mass.

The Science of Calorie Deficit and Weight Loss

Weight loss fundamentally comes down to energy balance. When you consume fewer calories than you burn (TDEE), your body uses stored fat for energy. One kilogram of body fat stores roughly 7,700 calories of energy. By creating a consistent daily deficit, you can predict your weight loss trajectory with reasonable accuracy.
