anecdotal evidence I know but here it goes:
back in gradeschool grade there was this kid in my class, his mom would bake him cake everyday and he was massively obese (go figure), whenever you played with him after school you'd basically OD on sugar from all the cake, soft drink and other crap he ate all day long, it had been like this ever since we started in school. sometime during the 6th grade we started picking on him for being fat, I mean big time, afterwards the fattie stopped eating cake every day and started swimming, and you'll never guess what happened next, he got thin... eating healthy and excercising makes you lose weight... whodathunkit😱
anyways, doubt he would have gotten off his fat ass if we hadn't called him out on being fat.
guess what fatties, being fat is a choice...
