(Chemistry professor Joe Schwarcz): The laws of thermodynamics will never be repealed. To lose weight you have to expend more calories than you take in. And as far as shedding pounds goes, it doesn't much matter how you cut calories. That's precisely the point Kansas State University nutrition professor Mark Haub wanted to make to his class a couple of years ago.

He figured that the prospect of a professor becoming a guinea pig was sure to get students' attention, especially when there was a chance that he might regret the idea. And it seemed that going on a "Twinkie diet" was a pretty good candidate for a "gee, I shouldn't have done that" type of experience.
