I don't think that fructose should be avoided like the plague either. That's just another version of labeling something as evil - the mainstream has labeled fat evil, the Atkins camp labeled sugar as evil, the vegetarians say that eating animals is evil, and the list goes on. Each of them is right to a degree but not entirely. I'm of the opinion that humans have been designed to eat just about everything, it's overeating that we have problems with.

Speaking of overeating, I think that on the weekends I practice what you call "insane overeating" - this weekend I put away about 16000 calories. This morning's weight was 191, up 7 from Saturday's 184. I don't do this for shock value nor is leptin anywhere on my mind when I eat like this - by experimentation I've determined that this (circa 2000 g) is the amount of carbs I need to reload well enough to go through the following week.
