If you are serious about learning exactly how your body uses and processes food read the book
Dine Out & Lose Weight by Michel Montignac from cover to cover.

It is written in easy to follow language and includes scientific research also.
The title is a bit misleading as it is not necessarily a weight lose book
but more of a education source for proper weight management and weight lose without dieting.

This is a Must Read for your health education.

You will be amazed at the things you learn.

I have not located a downloadable version of the book yet so till then you can view the website below.
