As someone who struggles to keep the weight on, I feel some sympathy.
Bad things happen when you rap when you shouldn't though.... Hopefully he hasn't joined the "I will live forever if I forcibly starve myself," movement. Yes, it's a real thing, my stepfather was into it and the things he juiced...

Not to mention deciding to intake his coffee via enema (I always drank tea when visiting my mom's house).
But my stepdad died of cancer. He tried regular treatment and then decided it wasn't for him, which was a shame as he would have lived decades longer..... Although, he was the type of dude who always seemed to have a very hard time being on earth and had a rough childhood, but I always thought it was a shame. RIP, stepdad (and I hope he got the sort of new age-y heaven he was seeking).
And, I hope rip tripper gets a little fatter, if he's skeletal. I won't be taking a look, I worked on an Eating Disorder unit for long ENOUGH.
