What are the potential benefits?
There are a variety of benefits that you could hope to gain by a diet, or by any other practice or therapy.
Possible benefits include protection against various diseases or ills, or the treatment or cure of a disease that has already beset you (and count obesity as a disease that may, or already has, beset you).
Another possible benefit is longer life—or better longer youth. Rather than living longer while aging at the same rate, what we really want is to age slower.
We're looking for the big wins. We'll try to direct your attention to things that have great potential. Life's too short for small wins.
How probable is it that those benefits are real?
Some things are long shots. In fact, most things are long shots. If you can find a therapy or practice which has a good probability of offering real benefits, you should recognize that as quite different from almost all ideas which are alleged to improve health.
We'll try not to waste time investigating ideas that don't have solid evidence behind them—that are mere speculation. There are too many.
How practical is it to follow?
For most of us, no matter how wonderful the potential benefits are, and even if it is probable that they are real, we're not really going to follow through with something if it is too time-consuming, uncomfortable, or incompatible with the other parts of how we live.
Practicality matters! The only health practice that is going to benefit you is one that you can live with, day after day, for the long-term. We'll focus on things you really can do in your own life.
How to judge a health practice
If a proposed health practice falls short in any of these three dimensions, then you shouldn't invest your precious time and resources in pursuing it. If a health practice excels in all three dimensions, then it is a rare and valuable thing that you should actively investigate. In these pages we hope to persuade you that we've spotted an idea of that kind.
