I don't think it's astroturfed...because they don't need to.

Good point, you're probably right. I guess even I'm surprised by how stupid people can be on Twitter, sometimes. It just seemed so freaking weird, I couldn't quite believe it.

Almost nobody wants to admit that the root cause is people shoving food in their faces.

Not just that, but the wrong food. If you're eating the right stuff, you can shove a lot of food in your face without getting fat. But, still, quantity is a big deal; some people just enjoy eating, eat things they shouldn't, and eat too much of it.

As you say, no matter the specific reason, it does often come down to 'well, you did this to yourself. Which is hard to swallow...so to speak.
