There’s this one weird trick doctors don’t want you to know… because it doesn’t work. It’s natural to hope for a one-size-fits-all, lose-weight-fast-and-forever solution. And if your sibling or friend is doing it or you saw it on TikTok, it can be tempting to just give it a try and see what happens. But what's the science behind these diets? Are some better than others? And will your nutritionist judge you if you try one?

On this episode of Mayo Clinic on Nutrition, we talk with Dr. Summer Allen about the good and the fad: what makes diets work (or seem like they do) and what you should consider before trying one yourself.
