Does eating ice burn calories

Answer 1

The heat of fusion (change of state from liquid to solid) of water is 80 cal/g. That occurs in atmospheric conditions at zero degrees Celsius. The body regulates it's temperature to be 37 degrees C (98.6 deg F). The sensible heat gain of the water then is an additional 37 cal/gram. The body's metabolism has to heat that water from ice to body temperature, 117 cal/gram of ice. Of course, there are 1000 physical calories per 1 dietary Calorie. Doing the math and simplifying the numbers a little, the water consumed as ice will gain 100 Calories/liter. Where does that heat come from if it isn't additional metabolic energy over and above the body's normal metabolism? Just be careful on the rate of consumption to avoid the painful ice cream head ache or the stomach ache caused by consuming too much cold. Chewing ice is not good for the teeth, so just drink crushed ice with just enough water to make the solution flow. Enjoy a smoothie, a slurpee or slush that is plain ice with no sugar. Flavor it with lemon or lime similar to what you do with a glass of water. Make the slushie with low calorie flavored water. In order to get the benefit of 68% of the energy, your beverage must be consumed as ice. If it is liquid water, that energy was absorbed by the room air. But, it seems that 2 liters daily would burn 200 calories.

Answer 2

All physical activity burns some amount of calories, so eating anything involves some muscular effort, and of course, ice has no calories. But if you want to eat something that will burn calories, raw celery (without dip or cheese sauce - salt is OK) is the best choice. Much better than ice.

That being said, more often than not what you are eating provides much more calories than it takes to digest (with the exception of celery as mentioned above) as it takes your body more energy to digest the celery than the calories it provides.

Answer 3

i just came to say that it is not 70 calories for 2 liters of ice just like water, stupid people say that cause they know nothing about how the world works, it is definetly more than that, i would say about 90+ calories for 2 liters. thats the reason you put ice in your drink and not ice cold water, cause it uses more heat to turn ice into water and than to raise its temperature than it would with water.
