Weight cycling is the repeated loss and regain of body weight.
You may have heard stories in the press claiming that weight cycling may be harmful to your health. You also may have heard that staying at one weight is better for you than weight cycling, even if you are obese. However, no convincing evidence supports these claims, and most obesity researchers believe that obese individuals should continue to try to control their body weight. People who repeatedly lose and regain weight should not experience more difficulty losing weight each time they diet. Most studies have shown that weight cycling does not affect one's metabolic rate.
