Regular rats eat 2000 calories a day?! Wow, what a metabolism.
I wonder whether the very high calories or sugar, moderate caffeine, or sth else in the coke increased transit speed significantly, so they excreted more of the other food they were eating? Could this happen or is this controlled for? Can't see it accounting for the whole difference, but maybe a part of it?
Yeah, rat metabolism is about 10 times higher than ours.
Fair points about the speed of transit, but if the rats pooped too much or had diarrhea the study would have said so. I have seen other studies on weight loss from supplements like African Mango and they did note that the weight loss was primarily from dehydration and calorie loss through loose stools and even vomiting. The studies were with rodents, obviously. If human studies showed these side effects, nobody would be buying that supplement.
