if i recall theres like 3500 calories in a pound? Basically you burn 3500 calories in theory you should have burned off 1 pound roughly.
For a chick to lose 2lbs a month by just changing her diet isn't a bad deal. She went from not hot to hotter, by a big amount. Supposedly chick's don't lose weight quick, i say fuck that put down the cake. But maybe this will be the miracle cure for some people. "4th meal" is pretty terrible to get, so if you could minimize the weight gain from being up drunk late.....imagine...
The only thing in question is how much was taco bell paying her to do this, and if the results were obtained by using say fitness instructors or other professionals.
