The metabolic consequences of ‘yo-yo’ dieting are markedly influenced by genetic diversity
The research investigates the effects of weight loss and weight cycling on metabolic outcomes, highlighting the significant influence of genetic diversity. C57BL/6 J mice showed a return to baseline metabolic conditions after weight loss, while genetically diverse DOz mice exhibited persistent metabolic issues and greater variability. The study concludes that weight cycling is detrimental, leading to hyperinsulinemia and elevated insulin secretion, with no lasting benefits from prior weight loss.
