But the high rate of attrition from the programme is a concern, he adds: less than one-third of people who are referred to the programme actually start it, and fewer still complete it.
This is always going to be the problem with any eat less and move more programs. Its not that all fat people are unaware of how to lose weight in this method (although some will and this will be useful for them) but that it is fucking hard for a lot of people to stick to, forever. Just look at the amount of people who successfully lose weight and then put it back on again a few years later, some studies have it at over 80% of people.
No other addiction program is trying to fix an addiction that you still have to consume what you are addicted to. No other addiction program is battling the pervasiveness of advertising and availability of "bad" or excessive quantities.
Until its treated properly as a proper addiction with similar alternatives like opiods to block behavior its just not going to fix itself.
