That's my beef with moralfagging about "oh, processed foods did it to us!"  You see that a lot in the media--that it's a diabolical conspiracy.  Food by itself didn't magically make you fat.  You chose to put it in your mouth.  If office jobs and vending machines guarantee obesity, why didn't Japan get as fat as America (and now Mexico)?  If having kids/thyroids causes you to be fat, whence cometh all the young men on Grindr and young women on [insert dating site here] that have none of those things and are unfuckable?
