why do mangakas draw fat people like theyre toddlers

Okay . this is more of a complaint than a genuine answer bc i half know what the answer to my question is (the standard is fat people have to look cute or else theyre 'disgusting' and making grown ass characters look like theyre 5 is the epitome of cute i guess)

ive read around 3 mangas with this problem and i dropped them all BECAUSE ITS SO. ANNNOOOOOYYYYING . GOD . IT FEELS SO UNCOMFORTABLE BC THE WAY SOME MANGAKAS DRAW FAT CHARACTERS IS LIKE A DRASTIC CHANGE FROM HOW THEY DRAW THINNER CHARACTERS AND ITSSOOO!;!:₱2&/;!;!;

ADDITIONALY . finding good yaoi/shounen ai with fat characters is such an abomination bc i saw this more commonly with those !!! and the 2 mangas i read with this problem used the same "this guy is fat so his classmates literally gropes his boobs and treat him like hes a girl" joke and its soooo. Bad. its so irking. i dont know it js pisses me off so bad

if u guys have genuinely good mangas with fat characters (yaoi or yuri!) PLEAAASE give them to me... show me to me rachel pleaseee send it to me

it doesnt have to be characters that are explicitly stated as fat because even just like. bigger than average characters would be good too! (like the character from she loves to cook anf she loves to eat)
