Yo-yo dieting or yo-yo effect, also known as weight cycling. The term "yo-yo dieting" was coined by Kelly D. Brownell at Yale University, in reference to the cyclical up-down motion of a yo-yo. In this process, the dieter is initially successful in the pursuit of weight loss but is unsuccessful in maintaining the loss long-term and begins to gain the weight back. The dieter then seeks to lose the regained weight, and the cycle begins again.
