How did Kim Kardashian lose 16 lbs in 3 weeks?

Celebrity weight loss methods are often extreme and not recommended for general health. Safe weight loss is 1-2 pounds per week. Rapid weight loss typically involves severe calorie restriction, intense exercise routines, and sometimes medical supervision that isn't sustainable or safe for most people. Focus on gradual, healthy changes you can maintain long-term rather than trying to replicate celebrity crash diets.
