Fueling Your Body

I have a friend from my hometown who, in my opinion, is really ruining his life. When we were in high school, we were both athletes. Neither of us is now, but I still love to get a lot of exercise and take part in physical activities. I still work out, and I still eat right. My friend… well, not so much.

He eats terribly, never works out, and drinks more than I’ve ever seen anyone else drink. And it’s making him fat. I don’t want to sound shallow – I really don’t care what my friend looks like. I’m worried about his health! He says he’s just getting older, and that “my metabolism will slow down, too.” What can I do to show him that what he puts in his body matters?
