Did you know that you can lose weight by eating ice cream? I was sitting at dinner the other day and I learned from an enlightened friend that the energy it takes to heat up really cold ice cream not only burns the calories in the ice cream itself but in fact is calorie-negative. Pretty sweet, huh? Check it out:
The energy intensity of ice cream, according to Haagen Dazs, is about 270 Cal/106 g = 2.55 Cal/g.
And now how much energy does it take to raise the temperature of that Haagen Dazs from 20 degrees F to 98.6 degrees F. Frozen ice cream has a specific heat of about 0.4 calories per gram degree Celsius. This means that eating the ice cream will burn about (.4)*(98.6-20)*(5/9) = 17 cal/g.
This means that for each gram of ice cream you eat, you burn 17-2.55 = 14.45 calories! Or is it Calories?
Wow! This is amazing! I can’t believe that you can lose weight by eating ice cream! We can probably lose mad weight by drinking ice water too! But why would you do that if you can eat Haagen Dazs?
