Answer 1

Weight cycling is actually the repeated losing and regaining of our body weight.When this happens with respect to our dieting it is referred to as the yo-yo dieting.This crash dieting rather slows down the metabolism.It is because when extreme weightloss happens in a very short period of time it will leads to a decrease in the metabolic activities which inturn results in more weight gain in the future.This is because of the increased hunger accompanied with the weight loss.
