Putting together an overall program seems like an interesting idea. If you're not just, say, doing a selection of random stuff, what are the guiding principles for finding mental activities, dietary plans, and physical exercises?

Off the top of my head, I can think of a comprehensive wellness program, though in its cultural context it is not regarded as such: yoga. Yoga is a traditional program that includes dietary rules, physical exercises (asanas), as well as mental stuff. The guiding principles are cultural and philosophical. Of course, people who practice all eight limbs of yoga are generally motivated by what they term spiritual reasons, rather than by the pursuit of wellness.

On the other hand, maybe we just don't know enough scientifically about wellness. At the end perhaps all we know is just meditate some, eat well, and exercise.

I wonder whether Andrew Weill has written on developing a program. This seems like it would be up his alley.
