In this 2:59 video Dr. Greger from NutritionFactsOrg comments on the Ice Diet that fortunately never took off, as the heat cost of the body trying to turn ice into its drinkable state is better obtained by just turning up the AC or wearing less layers outside. He uses a report from researchers in Spain to support his claims. Dr. Greger also discusses how such a diet would have come about, namely that since plant-based diets offer great slimming successes, wouldn't taking its unique high-water content as the key to slimming success be a good idea for weight management? Research suggests that instead of dieting on ice, or downing massive amounts of water during meals, we should preload on water thirty minutes before.
