The idea behind "Turn Off The Hunger Switch Reset Your Brain to Change Your Weight" is that our problems with weight are because of imbalances in out brain chemistry. The messages in our brain have gotten out of whack.

The beautiful thing about this diet is that it's not an diet at all. Also, no exercise is required.

The book has an easy quiz in four parts that allows you to identify where your brain chemistry is going wrong. You'll be able to pinpoint why other diets have failed for you. Dr. Rivas uses a similar test when someone sees him in person.

The solutions he offers target these specific problems. Supplements, specific nutrients and prescription medication are used. Ultimately, once you track down what you need to change, you'll need to make contact with a doctor who is willing to work with you on this approach to weight-loss. Together, with your doctor, you'll create a program that fits you.

Craving, over-eating, mood swings and other related problems are also cleared-up with this approach, since these are problems are all related to why you're having little success with conventional weight-loss programs.

Dr. Rivas' approach is to get to the heart of the matter, what's going on inside your brain. All the methods of typical diets (like calorie counting, low-carb, low-fat, etc.) can all be put aside. Once you solve the real problems of brain chemistry imbalance, you'll just naturally choose healthier lifestyle and foods, without a struggle.
