I mean, that's a little like going "hey, look at the alcoholic scared to drink in public! or lol, look at that brokeass trying to save money!" Also possible fatty is trying to eat better and knows that he's not going to have a reasonable portion of delicious bbq (or is trying to keto, IF, or whatever). Much easier for me to skip a meal than to consistently control portions, and you can bet your ass that I've never been embarrassed to eat. (I'm quite good at it, having had so much practice!) Obviously fatty habits got people fat, but that didn't happen over night, and undoing it doesn't happen overnight either. I've been losing weight pretty consistently for maybe 3 years, and I'm still fat. And God knows how many times I've tried and fallen off the wagon prior to that.
