Re-bound weight gain
1: Re-bound weight gain: With crash dieting, the body conserves the little energy that it gets and the metabolism slows down. The dieter hits a plateau and loses motivation to do more and starts eating again, and the weight gain this time around is likely to be higher as a result of an already slow metabolism.
This rebound weight being higher, often propels the dieter into another bout of crash dieting. This cycle of dieting and weight gain is often referred to as 'yo-yo dieting' and only results in greater weight gain in the long-term.
