A recent study has concluded that the people you hang out with have a greater impact than your genes in determining whether you're overweight or not. Really?
In looking around at who I 'hang out with', the study's conclusion seems to have some merit. Most of my friends are on the leaner side and in pretty good shape, and despite the occasional splurges, everyone exercises and watches what they eat.
I do wonder about cause and effect, though. Are we leaner because we hang out together? Or do we hang out together because we're leaner -- a by-product of having common interest in nutrition, fitness and weight-consciousness? Or is it all just happenstance, and I just happen to randomly be in a leaner group?
Now that I think about it, it does strike me that I have very few....if any...overweight friends. In fact, I can't really think of any. Must be a reason for this.
