Ice, ice, baby...
Snow cones the key to losing weight? I'm in. From James Hamblin, writing in
When you eat a significant amount of ice, your body burns energy to melt it. Eating ice should, by the logic of this diet, also provide some level of satiety, if only so far as it physically fills space in the stomach and mouth.
By Weiner's calculations, ingesting one liter of ice would burn about 160 calories, which is the energy equivalent of running one mile. So you get to eat and burn calories. Ever since the death of upward mobility, that has been The American Dream.
What's more, it's probably safe. "Ingesting ice at this level should not have any obvious adverse consequence in otherwise healthy persons," Weiner, who trained at Johns Hopkins, writes. "For the vast majority of adults and children, there does not appear to be any contraindication to the use of the Ice Diet right now."
One piece of evidence for the safety of ingesting substantial amounts of ice, Weiner notes, comes from the case study of the 32-ounce 7/11 Slurpee, from which he concludes, "The ingestion of one liter of ice per day appears to be generally safe."
