I found this book very interesting. Such as: When we are born and are babies, we eat when we are hungry and when we don't want any more, we are done; nothing can get that baby to open up for more. Look at animals in the wild.....none of them are overweight. They eat for hunger and survival.
To correct the appetite, it won't be a diet in the customary sense of the word. It will be a personal, customized Appetite Correction lifestyle: a set of choices, habits and activities that works for YOU and with YOUR body rather than against it.
Deep within our brains our appetite (the drive to eat) is generated by the appetite center. It is one of the many functions maintained by the body's "autopilot" system. It is at the core of the brain alongside other basic functions that are essential to life. The appestat in the brain determines that you need to eat and you WILL eat unless the drive is overridden by another brain-core system such as fight or flight. The appestat initiates eating behavior and overrides the objections coming from the cortex.
So for so many people to be overweight something is confusing a lot of appestats, because appetite is clearly driving people to eat when they don't need to. You can't directly adjust your appestat, but by exerting your conscious control on some things, you can influence your appestat so that the amount it drives you to eat is corrected to where it should be.
Which brings us to the point of this book in how to correct your appetite. The author gives you the rules (for those rule loving people/"how do I do this?") as well as a "toolkit" to help you tweak and customize behaviors (affirmations, portions, exercise, etc) to make this a comfortable fit with your life that you can maintain indefinitely. You can use this way of eating along with any diet choice you prefer (vegetarian, vegan, low carb, Mediterranean, etc).
