                                Studies suggest that as few as 5% of people who lose weight on a crash diet are able to keep it off long-term, making the appeal of an extreme crash diet a short-lived illusion. While the promise of shedding pounds in a very short timeframe is tempting, the severe calorie restriction and unbalanced nutrition can pose significant threats to your physical and mental health.
