I did almost the same thing in high school physics. I felt like I'd discovered magic weight loss secrets until I took into account that food is listed in kilocalories.

Then we calculated how much liquid nitrogen you'd have to drink to offset a 2000 kcal basal metabolic rate. The volume wasn't shocking-- under 10 L, if I remember correctly. We decided it wouldn't be a very healthy diet, though.
