Don’t be fooled by the presidential burger runs. Obama and Congress are moving across several fronts to give government a central role in making America healthier — raising expectations among public health experts of a new era of activism unlike any before.

Any health care reform plan that Obama signs is almost certain to call for nutrition counseling, obesity screenings and wellness programs at workplaces and community centers. He wants more time in the school day for physical fitness, more nutritious school lunches and more bike paths, walking paths and grocery stores in underserved areas…

To some, it smacks of a “nanny state on steroids” — but for others who fret that America is turning into one big Overeaters Anonymous meeting, Obama’s prescription is like a low-fat dream come true…

The whole situation has libertarians craving a basket of onion rings and a beer.
