If you're a decent person and you've ever spent any time around families without.... a generational structure of wisdom, it's easy to be compassionate towards people who grow up that way and for whom making what seem like obvious good choices to folks like most of us is much much less obvious and much more difficult. And just a rudimentary understanding of the world and numbers and statistics can inform you how you should understand things in the aggregate while also recognizing that people aren't limited to whatever "their" average is and have the ability to make choices to change their lives. Poor people (in the aggregate) eat like shit because it's generally cheaper and easier and the wisdom of making different choices has been spoonfed to them less and their lives are fucking hard. I feel a lot of compassion for those folks, and also I posted in the thanksgiving thread about the wife's little 1 year old second cousin from Louisiana walking around with coke in a baby bottle, holy fuck wow. Maybe it was a cherry coke, had a little vodka. I dunno. That little baby is probably going to be feeding her own little baby cheetos in 16 years. Or maybe not.
Goddamn.
Anyways, it's structurally more difficult for poor folk in the aggregate to be thin for a multitude of reasons. Most not all of them could make different choices and not be fat, but it's not easy to make those choices and I'm not sure anyone here is arguing that it is.
even this is really saying the same thing that people who swear by calories in/calories out are. those folks recognize that you can plateau, your body can slow down if it thinks it is starving, its harder to keep a deficit if you're eating shitty calories, not everyones body burns calories the same way all things equal. But there's no such thing as magic.
