Yo-yo dieting not considered harmful?

  1. This is splitting a very fine hair, and it should not go unrecognized. This study indicates that yo-yo dieting doesn’t make it any harder to lose weight. But there is a separate claim, that this study supports, which is that attempting to diet results in net weight gain.

    Also, saying “it isn’t any harder to lose weight” if you’ve been dieting before is small comfort, since dieting is so dramatically ineffective overall. The cyclers also did not differ from the non-cyclers with regard to the impact of diet or diet-plus-exercise on weight loss, percentage of body fat and lean muscle mass gained or lost. Yes, but what was that impact? That they lost 5-15 pounds over the course of 1-3 months and then gained it back later? Whoop-dee-doo. Without access to the journal, I can’t answer that question, but I’d lay money that the resulting weight loss was trivial and short-lived. I’d also lay money that the participants were heavier at the end of the year following the end of the study than they were at the beginning of the study.

    I would think that cycling would help you lose weight, especially if you went up a bunch of hills and stuff.

     There’s a big difference between “does not make it harder to lose weight” and “is not harmful”. Does this study address other health risks of yo-yo dieting?

    They do provide a couple of indicators that SOME problems previously associated with yoyo dieting, like heart disease and diabetes, may not be caused by this.

    Maybe the previous studies have found correlation?  If you’re obese, you tend to both yoyo-diet AND have health problems?
