Ahlan! reported some months ago that Renée Zellweger credits her ability to lose weight quickly to the ice diet, and now her ‘eating’ plan is hitting the headlines as an American doctor has suggested it really is the best way to lose weight. The diet involves eating about a litre of frozen water a day alongside a healthy diet in order to speed up your metabolism and burn calories much faster. American digestion expert Dr Brian Weiner, who founded weight loss website www.theicediet.com, suggests “the more you eat, the more you lose” as your body has to work harder to thaw the ice. Sounds pretty cool!
