Losing 5.5 kg (12 lbs) in 3 days is possible, but it’s mostly water weight, not fat, and can be harmful.

Rapid weight loss methods like very low-calorie diets, juice cleanses, diuretics, laxatives, and extreme workouts often cause dehydration, nutrient deficiencies, muscle loss, and mental strain. These methods don’t promote fat loss and can lead to long-term health risks, including a slowed metabolism and potential binge-eating. Plus, the weight usually returns.

A healthier approach includes a balanced diet with whole foods, a moderate calorie deficit (500–750 calories/day), regular exercise (cardio and strength training), proper hydration, and stress management.

Instead of quick fixes, focus on sustainable habits for long-term success. Fast weight loss isn’t worth the health risks—aim for steady, safe progress.
