PART III: How Should I Eat? (Not too much.)
Rule #56 - Limit your snacks to unprocessed plant foods.
Remember the old taboo against "between-meal snacks"? Decades of determined food marketing have driven the phrase from our consciousness. But the bulk of the 500 calories Americans have added to their daily diet since 1980 (the start of the obesity epidemic) have come in the form of snack foods laden with salt, fat, and sugar. If you are going to snack, try to limit yourself to fruits, vegetables, and nuts.
Eat food. Not too much. Mostly plants.
