But for some reason, starting around 1980, the two factors uncoupled, and food intake started to rise despite exercise continuing to decrease.

The brain has some pretty sophisticated mechanisms to determine when we’ve eaten enough; these usually involve estimating food’s calorie load from its mass and fiber level.

But modern food is calorically dense – it contains many more calories than predicted per unit mass – and fiber-poor.

Various groups tried to design various new forms of rat chow with extra fat, extra sugar, et cetera, with only moderate success – sometimes they could get the rats to eat a little too much and gradually become sort of obese, but it was a hard process.

Then, almost by accident, someone tried feeding the rats human snack food, and they ballooned up to be as fat as, well, humans.This fools the brain into thinking that we’re eating less than we really are, and shuts down the system that would normally make us feel full once we’ve had enough.
