i'm not sure if this is the same person that i'm thinking about, however, there was a guy from mexico that was over 600 pounds or somewhere around that range.
however, when it comes to getting this fat, i think that this is by choice. obviously these people aren't eating the best types of foods, which is due to either their job careers or their upbringing. he might have a hard time keeping extra weight off, but a half a ton isn't considered extra anymore, it's considered gargantuan.
