Easy to read is a comprehensive analysis of the mechanisms that are involved when you eat. Systemic analysis and a time scale which shows the disparity between the evolution of our living environment and therefore our "feeding" ... and the ability of our body to adapt to it. A real awareness of what is really eating, our true nutritional needs, the pleasure of eating and our deficiencies. I found the first sentence of the book as a good summary of the latter. "Hunger is an impulse, appetite is a balance" ... analysis of this phrase takes on the book. I recommend it to all who want a balanced approach to this problem is our modern weight!
