Repeated bouts of weight loss and regain.
Rapid increases and decreases in body weight.
Weight cycling (yo-yo syndrome) is the repetitive cycle of weight loss and weight gain. Off and on fad dieters typically experience weight cycling.
Phenomenon of successfully losing weight only to gain it back within a few months, followed by renewed dieting, weight gain and loss, and so on. Also known as yo-yo dieting.
Frequent bouts of shedding and gaining weight can lead to a higher percentage of body fat with each subsequent weight gain, which can result in a decline in Resting Metabolic Rate (RMR), making it harder to achieve weight loss in the future.
