They use the internet and find people who tell them that it's not their fault. It's the fault of vegetables for being so expensive, even though vegetables are cheaper than junkfood. It's the fault of food deserts, even though they live in walking/driving range of half a dozen full-sized super markets. It's the fault of their genes, even all 8 of their great grandparents were fit. It's anybody/anything's fault, except their own. And so they stay fat, and join the ranks of those who perpetuate these fat-excusing myths (on full display throughout this discussion section.)
