Someone being a bit overweight is one thing, life can get stressful and things can happen. Someone who's a bit chubby can still be cute with the right attitude. However someone who clearly let themselves go and doesn't care isn't cute at all. It screams they don't care about themselves or those who they do or potentially would care about. Getting fat is kind of interesting. You can get to a certain point and not realize it, but there comes a point where you just know and you have to make a choice. Speaking as someone who used to be fat, I dont think anyone can have the same loathing for obese people as a former fatty. I mean holy shit you're just a blight to everyone around you, particularly when it gets so bad you have to fucking call 911 to have the fire department pick your fatass up because you're too obese and weak to lift yourself. The only benefit anyone gains from being fat is if you stay active while fat and work it off you end up with tree-trunk thick muscular legs that can carry you up a mountain with ease and you have the ability to squat an elephant.
tl;dr - being fat is
NOT cute. Its a slovenly lifestyle that makes everyone around you think you're a gross person with no self control or discipline.
sorry if that got a bit heated
