Ok. But the percentage of adults who are overweight or obese is somewhere around 70%. If we presume 10% is not preventable - that is they have a med condition - then what of the other 60%? Who is feeding those people? Who is forcing them to the sofa?

I understand it's not that simple (e.g., gut bacteria has been tied to weight control). None the less i know people who had what I would consider serious med issues (e.g., cancer) and made no change in lifestyle.

Yes, I'm generalizing. I apologize. But the obesity rate doesn't match well with self responsibility.
