I guess I'll start with one.

I recently read The Yoga of Eating by Charles Eisenstein.

This is about as far along the 'hippie' spectrum as I go - and it's pretty hippie!! The author doesn't describe any particular type of diet, indeed, he hardly talks about specific foods.
Most of the book is devoted to a discussion of how we relate to food, and how to tune into our bodies and 'ask the body what it needs'. It relates very closely to mindful eating strategies.
Lots of the book was very insightful. (Insightful to the point it made me cry, but I'm going to blame that on hormones and not the book per se. :eyeroll: )
