Hi guys, this might be a bit of a tough subject, I hope it can stay contained.
I have a friend who during his late middle school/early high school years dealt with bulimia. I'm not sure if he was a binge eater (in the extreme sense) but I do know he was a purger, and has struggled with weight for most of his life.
He has for the past year or so asked me to help him out to try to tackle the weight issue in a healthy way, and now I want to introduce him to the PB. However, he seems to believe that only exercise will help, because he thinks his metabolism is ruined due to his disorder years ago.
My question is, is he right? He stopped completely I would say around 2000, maybe 2001? It's not a subject I'd want to bring up with him, so I can't get a more accurate number, but it's definitely been over 7 years.
I've done mild research on the subject and can't find a definitive answer, and I believe maybe he's holding on to that as an excuse to simply exercise and not try to eat better. However, he doesn't really exercise either, ever, not because he's lazy but because he had money issues and he's one of the types that thinks you need a gym to work out. I don't see my friend making flat out horrible choices food-wise, but I have noticed an increase in his weight in the last 2 years or so and I want to try to help him out.
Should I wait until he asks for advice again? I don't know how to bring it up sensibly. I know he's not currently doing anything to better the situation, but I think with better information he could make some adjustments. He's a big food fan, in the sense that he loves to try different stuff and I think he'd enjoy cooking Primal. He's not much of a junk food eater at all, but does work in a place where he's probably sipping on sugary drinks and treats more than he should.
Would it be okay to try and get him on fresh foods, which I think he already knows are better for him, before hitting on the sugar issue? A lot of people (myself included, at least when I started PB) can be put off by the list of "foods" that are suddenly unacceptable ...
I'm looking for a yes/no answer on the metabolism issue, and maybe some advice on how to approach the conversation for optimal results, that result being my friend trying to get on a healthier track and start to see some weight loss without having to "hit the gym" right away...
Thanks in advance 
I used to seriously post here, now I prefer to troll.
