Body-weight cycling, sometimes referred to as yo-yo dieting, may be harmful to the kidneys for people with type 1 diabetes, according to retrospective data analysis.

Body-weight cycling (also known as yo-yo dieting) has been shown to significantly increase the risk of kidney disease in people with type 1 diabetes, regardless of body mass index (BMI) and other traditional risk factors,
