Visiting my family for the first time in four years. Always been fat and making my little brother day. What do I do? This is half rant, half seeking advice:  My dad has literally always been fat. It wasn't awful when I was younger, but now he has hard fat that makes him look nine months pregnant with triplets. It's ruined his knee- he has to get knee replacement surgery.  My stepmom is also overweight, no where near him and trying to lose. But her family scares the shit out of me. Morbidly obese, the lot of them.  I have a five year old brother. Haven't seen him since he was two. He weighs 74 pounds!! That's more than half my weight!! He's constantly snacking. Only drinks juice, has ice cream twice a day, candy bars, giant cookies I can't finish, and eats more at meals than I do. And that's only what I see- who knows how he eats at school.  I've tried to breach the subject delicately- my dad's response, "we've noticed. Now he isn't allowed to eat his two candy bars before bed anymore."  What the hell?! Two full sized candy bars before bed, every night? I'm so worried about this kid. And I don't live here so I can't help influence him as much as I want to. The only time he ever has milk is when a cookie is dipped in it. And then he dumps the rest.  What do I do about this?! TL;DR my obese family is making my 5 year d brother fat, also think my dad is slowly killing himself.  edit... wow, just noticed my typo. They're making him FAT not day...
