'I resolve to eat less food' sounds good in theory, but it's often hard to sustain. And if you believe that it's all willpower, then you're likely to be upset with yourself if you don't succeed.

If you indulge yourself one day, you can eat more healthfully the next. To the degree you move in a healthful direction on the food spectrum, you're likely to feel better, lose weight, and gain health.

It costs less to eat and live more healthfully. Walking, loving, meditating, and quitting smoking are free and require no special equipment.

Concepts such as 'risk factor modification' and 'prevention' are often considered boring and they may not initiate or sustain the levels of motivation needed to make and maintain comprehensive lifestyle changes.

How you eat is as important as what you eat. If I eat mindlessly while watching television, I get all of the calories and none of the pleasure. Instead, if I eat mindfully, paying attention and savoring what I'm eating, smaller portions of food can be exquisitely satisfying.

A valid scientific theory is predictive, verifiable, and replicable. To me, that's beautiful.
