Researchers found that the long-held belief that yo-yo dieting harms your metabolism may not be true. A new review of decades of studies suggests that repeatedly losing and regaining weight, often referred to as weight cycling, does not cause lasting damage to health. Instead, the researchers argue that the benefits of attempting to lose weight generally outweigh the risks associated with regaining it.

This finding is significant for anyone looking to improve their health as they age. Many people are discouraged from trying to lose weight due to fears that yo-yo dieting could lead to muscle loss or a slower metabolism. However, the review indicates that regaining weight after a diet does not necessarily make you worse off than before. While weight regain can reverse some health improvements, it does not appear to increase overall health risks compared to staying overweight.

The evidence comes from a comprehensive analysis of various studies, including observational research and clinical trials involving both humans and animals. The researchers found no consistent proof that weight cycling leads to excessive muscle loss or metabolic slowdown. Instead, they emphasize that regaining weight often returns individuals to their baseline health status rather than causing additional harm. This perspective is especially relevant as new obesity medications become available, which may lead to temporary weight loss followed by regain.

Ultimately, the researchers encourage individuals with obesity not to be discouraged by the challenges of maintaining weight loss. The message is clear: trying to lose weight, even if it doesn’t result in permanent loss, can still provide valuable health benefits.
