I guess it comes down to...
...1. How much you value human life and
2. How much you want to reduce the burden of obesity on the health care system. Obesity carries quite a financial cost. The graph here should be right up your alley.
That said, I think they're going too far. Encourage, educate and let the dice roll. Education has been the thing really lacking. A lot of people are just ignorant of good nutrition and how to fix good nutrition. The cook the way their parents before them did. And we are less and less active. So, add exercise to the educate and encourage.
