In retrospect, we're not surprised at that. It's difficult to get huge numbers of diverse people to change their eating habits.

What people like us in the nutritional-sciences field try to get people to understand is, there are no quick fixes. Drastically reducing carbohydrates or eating grapefruits all day isn't going to work in the long run.

What we find is what the sensible books have been recommending. These were people who had a high-fat diet. We cut fat below 30 percent and they did not gain weight.

The young people to whom he speaks have no hope. What Stan presents is hope that they too can change. He is worth far more to society alive than dead.

If we can be the best people we are as individuals, then that's the way to change the world.

I don't believe in sweeping social change being manifested by one person, unless he has an atomic weapon.
