Debunking a Dieting Myth: Why Weight Cycling Isn’t as Bad as You Think

The fear of “yo-yo dieting” has long plagued those attempting to shed pounds. A perpetual refrain warns that repeated attempts at weight loss will leave you with a damaged metabolism and a body composed mostly of flab. However, this notion may be nothing more than a vicious cycle of misinformation.

A recent review published in The Lancet Diabetes & Endocrinology sheds light on the supposed ills of weight cycling. Researchers Faidon Magkos and Norbert Stefan reviewed decades of studies involving humans and animals to determine whether repeated weight loss followed by regain causes lasting harm. Their findings are reassuring for those who’ve struggled with the frustrating pattern of losing weight only to watch it return.

The review’s authors acknowledge that regaining weight can undo some of the positive effects of weight loss, such as improved blood sugar and cholesterol levels. However, this does not necessarily mean a person becomes less healthy than before. This distinction has far-reaching implications for how we approach obesity treatment.

The findings arrive at a time when newer obesity medications are gaining popularity. These drugs can produce significant weight loss – but what happens when patients regain weight after stopping treatment? Does this pattern constitute “yo-yo dieting” in its most insidious form? According to Magkos and Stefan, not necessarily. Even temporary periods of weight reduction can still provide important health benefits and improve quality of life.

The idea that “yo-yo dieting” is inherently bad has become ingrained in popular culture. It’s often cited as a reason for avoiding weight loss attempts altogether. However, what if this notion is nothing more than a self-fulfilling prophecy – a myth perpetuated by our own fears and misconceptions about the human body? Magkos and Stefan’s review suggests that we should reevaluate our stance on weight cycling.

Rather than viewing it as an inherently unhealthy pattern, perhaps we should see it for what it is: a natural part of the complex dance between diet, exercise, and genetics. This nuanced understanding has significant implications for obesity treatment. Rather than relying on simplistic notions of “good” vs. “bad” diets or weight loss strategies, perhaps we should be focusing on more evidence-based approaches that take into account the complexities of human biology.

The review is a welcome respite from the dieting doom-mongering that dominates our airwaves. By shedding light on the myth of “yo-yo dieting,” Magkos and Stefan offer a message of hope – not just for those struggling with weight loss, but for anyone who’s ever felt like their metabolic fate was sealed by some arbitrary notion of “proper” eating or exercise habits.

In the end, trying – and even failing – to lose weight is not inherently bad. But giving up altogether may be.
