Drinking cold water forces your body to expend calories to heatthe water to body temperature. Drinking ice water requires evenmore energy, because energy must be used to melt the ice to water,then heat the water. There are instances where people stranded insnowstorms died from hypothermia (decrease in core body temperaturebelow the level required for organs to survive) due to eating snowin an attempt to stay hydrated.

The point is it is clear that once they are inside someone, iceand cold water take energy to warm up to body temperature. Thatmeans it is possible to use this to burn off calories and loseweight. The idea would be to drink lots of ice water, and theenergy used to warm the water up would come from stored fat.

From a thermochemistry perspective (i.e., aside from theproblematic aspects of dieting and health risks associated withrapid weight loss), explain why you think this method would beimpractical or ineffective as part of an overall plan for losingweight?
