As an overweight guy, I make them all the time. Is there healthier ways to lose weight, sure. But I obviously ignored those to get here. I understand why people find it bad to fat shame people, but about oneself should always be allowed in my book.
I don't really like this one. If you're gonna do a fat joke, at least commit fully to the bit. It's not your metabolism, its all the shit you shove down your gullet
