I've made a concerted effort to consume less "junk media" in the last couple of years. In that time I've gotten an Amateur radio licence, I've built a couple of keyboards and speakers, I've started golfing (after a 20 year hiatus), I've learned to bake bread (from scratch, including grinding wheat!), I've read a lot of novels, and I'm happier for all of it.
Everyone has to work -- this is not unique to the United States. But outside of that, eating and living healthier is absolutely possible, it just takes some effort.
Get a hobby (or several!)

my hobbies included waking and running around, making stuff on an old laptop (I kept that one!), reading, making planes out of whatever material i could get my hands on that sort of stuff. i ate pasta, eggs, rice, water, tomatos. i never cared about eating the same thing everyday (i still don't but ive learned to eat a little better).
theres plenty more hobbies, obviously none of these being forbidden in the USA lol. and most make more money than I did, not to mention have food stamps and the like.

You could come in, look at the latest Creosote burns on his skin, and tell him that something-- anything! --would be better than watching an hour of Football.
And, while you're at it, you could try to convince him that smoking's bad too.
Also, he should probably quit smoking (unclear if it's too late for that, if so I'm sorry)
Sorry! I wasn't in a great place when I wrote my reply last night. I'd delete it if I could.
