Q:
What harm does eating ice does to your body? I eat ice everyday all day.

A:
It does take energy to melt ice and then to warm it up to body temperature and you might wonder about your dietary energy balance. Let's do a quick calculation:  it takes about 334 kiloJoules to melt a kilogram of ice and then an additional 140 required to warm it up to body temperature for a sum of 474.  This is about 112 nutritional Calories.  I suspect you don't eat a kilogram (2.2 lbs) of ice per day so the caloric deficit is peanuts compared to the 570 Calories in a 3.5 oz bag of peanuts.. 
On the other hand, cracking all that ice with your teeth might not be too 'cool'.  Ask your dentist.
