Was gonna post this in redpillparenting but that’s a ghost town.

So I’m 19 and my bro is 13. Our parents are separated, live with our mom. At 13 I was in great shape, popular in school, competed in kickboxing and bjj. Meanwhile my bro is becoming skinny fat, spends literally the entire day playing Mineshaft or fortnight with other losers on Xbox, sleeps until mid afternoon and plays xbox from the second he wakes up till he goes asleep. Barely eats, picks at junk throughout the day. We tried to get him to join bjj, football, basketball, boxing, athletics. He either flat out refused to go and throw a temper tantrum, or go and take 0 participation and never wanted to go again. His only interest is playing with those fucking freaks online.

I try to lead by example but he doesn’t follow. I went as far as telling him he’s going to be a virgin weirdo in high school and he will be nobody. Harsh but he still didn’t take it on board. I really don’t know what to do anymore. I don’t want my bro going up being a skinnyfat faggot when he has the potential (tall, good looks) the way I did. What should I do?

TLDR: little bro is a fag, need to fix
