It is possible to lose 10 pounds in a week, but it is generally not safe or sustainable. Most of the weight lost in such a short time tends to be water weight rather than fat, which can be quickly regained once normal eating resumes. Experts recommend aiming for a safer and more sustainable weight loss of 1 to 2 pounds per week to avoid health risks such as malnutrition, fatigue, muscle loss, and metabolic slowdown. Rapid weight loss may also lead to side effects like dehydration, electrolyte imbalance, and other health complications. For lasting results, a combination of a balanced, nutritious diet and regular physical activity is advised, rather than extreme calorie restriction or fad diets aimed at quick loss.
