my take: I've read this several times. Marc David is a pioneer in the field of the psychology of eating.
Half the chapters are about HOW TO EAT and half are about WHAT TO EAT ... the "diet" in the title refers more to actual eating than to a specific way to restrict calories. Each chapter is one specific practice, so if you take it a chapter a week it's an 8-week program. (I read it all at once and then started to put into practice.)
It's a good read with many client stories to illustrate his suggestions. It's a revolutionary way of approaching food and has changed the way I eat and think about food.
I use this as the source for teaching nutrition in my life skills class and it never fails to surprise and inspire the ladies. They love learning about Vitamin O and Vitamin P. You might, too.
my source: Jill Tanis. Thank you.
my verdict: Highly recommend.
