I am, especially since about a year ago he was starting to buy the HAES bullshit. He has/had a really fat female friend, eventually saw through her crap excuses and I think doesn't talk to her anymore. Now that he's an older, more independent teen, he's seen what eating junk vs. eating well and exercising has done to his own body. He's loving the confidence and energy level. He is a late bloomer, and going back to school this year, everyone is freaking out about his transformation over the summer.
