Patient-Friendly Explanation

Weight cycling, commonly called yo-yo dieting, happens when you lose weight on a restrictive diet, only to regain it — sometimes more — once you stop. Each cycle can be frustrating and disheartening. Research suggests that repeated weight cycling may slow your metabolism over time and make subsequent weight loss attempts progressively harder.

Clinical Definition

Weight cycling refers to the intentional or unintentional repeated loss and regain of body weight, typically defined as a fluctuation of 5–10 kg or more over multiple episodes. Epidemiological studies have associated weight cycling with increased risks of cardiovascular disease, hypertension, and all-cause mortality, though the causal mechanisms remain debated. Potential mediators include loss of lean body mass during weight loss phases (with preferential fat regain), metabolic adaptation, and increased visceral fat deposition across cycles.

Why It Matters

Breaking the yo-yo dieting cycle requires a sustainable, medically supervised approach rather than quick-fix diets. At NuLifeCare, we focus on long-term lifestyle changes, behavioural strategies, and when appropriate, medical therapies that support consistent, maintainable weight loss — avoiding the metabolic harm associated with repeated weight cycling.
