These days fat itself isn't seen as bad (which I personally dont have a problem with since I actually like chubby girls) but because of that even if you're obese the only thing you need to do in order to be seen as attractive is hide the universally negative features that universally comes with a fat body, droopy flab and unappealing body-shapes. Its the reason why all drawn fat characters save a few exceptions have a smooth soft belly and perky chest, when in reality fat people often have an uneven flabby stomach and large droopy boobs due to excess fat-accumulation.
