The latest way to burn fat without actually doing anything: FreezeAwayFat Cool Shape shorts, which promise to—you guessed it—freeze away fat. Turns out there may actually be something to it, writes Julie Deardorff in the Chicago Tribune. The shorts, which come with gel inserts to freeze and then wear, promise to activate “good” brown fat cells, which burn calories, while killing off “bad” white fat cells.
Cool temperatures can in fact activate brown fat cells, says one doctor, but he’s less sure about the claim that cold will also kill white fat cells. It’s “not exactly rigorous science,” Deardorff concludes. “Still, even if there’s no evidence showing the polyester/[Lycra] shorts can help you freeze your butt off, they are certainly refreshing”—so if you don’t mind the $99.95 price tag, “simply wear them on a hot July day.”
