"Health," Dr. Andrew Weil writes, "is a dynamic and temporary state of equilibrium destined to break down as conditions change." In other words, there's no such thing as the type of health that allows you to feel equally great every day of your life. Instead, Weil suggests, your goal should be to improve your resilience to disease, and while you're at it, feel more joy and strength.

As to how you should gain this strength, joy, and resilience, Weil doesn't come on with a hard sell to give up every bad habit or all of the foods you enjoy. Instead, he suggests gradual changes: clean your pantry of whatever cooking oils you have there, except olive oil; start taking vitamin C three times a day; walk a few minutes a day; eat some fish and broccoli. The program is so simple and sensible that anyone trying it probably will feel better in a week.

The program then gets progressively more involved--more supplements; more of a shift toward a diet based on whole grains, fruits, and vegetables; more exercise. Besides these steady changes, each week's program has a focus: In week 2, you start drinking bottled or filtered water; week 3 focuses on organic produce; week 4, on sleep; week 5, using a steam bath or sauna; week 6, trying a "universal tonic" like ginseng; week 7, volunteering in your community; and finally, in week 8, figuring out how to integrate permanently the elements of the program into your life.

Even those who don't go for the entire program will probably find something here to like--the recipes, maybe, or the suggestion that you cut back on strenuous types of exercise like running and competitive sports in favor of brisk walks. It's perfectly useful either way: as a total lifestyle overhaul, or a series of suggestions, any one or two of which will probably help you feel better. --Lou Schuler
