i used to think like you but i realize its wrong. some of these people just have bad genetics. they need far more will power, restraint, and hard work than the average person not to be fat. everyone's body isnt the same, so you can't be like well i can do it, why can't you ? if you had their genes you would be fat as hell too most likely.
furthermore this article is about a patient that has problems unrelated to the obesity, and doctors not even being able to see past the fat so they don't even try to look at what else could be wrong. that is wrong.
trust me i understand you obese people disgusting, they do look gross. but they have a struggle more difficult than you can imagine.
