Publisher's Summary

No wonder it's so hard to lose weight, our bodies are designed to keep weight on at all costs; it's a matter of survival. It's embedded in our DNA. Our diet has changed dramatically over the past 10,000 years, but our genetic blueprint has not; our bodies are not designed to process the types of food we are fed today. It's like putting diesel fuel into a regular car: it just won't work. And making matters worse is the fact that diets don't work either: less than six percent of weight-loss attempts succeed. The average person who goes on a diet actually gains five pounds.

But a medical revolution is under way, finally showing us precisely how the powerful forces that keep weight on can actually be reprogrammed to automatically burn fat and keep weight off for good. The concept is simple. By learning how to work with our bodies instead of against them, we can ignite the natural fat-burning furnaces that lie dormant within us. For the first time ever, Dr. Mark Hyman makes this new science of weight loss available to the general public.

This medical revolution is based on a groundbreaking concept called nutrigenomics, the science of how food talks to our genes. This science is actually startlingly simple. Food contains information and instructions for our bodies: eat the right foods and send instructions of weight loss and health; eat the wrong foods and send messages of weight gain and disease. After spending the last 10 years conducting pioneering, hands-on research with over 2,000 patients at Canyon Ranch, one of the world's leading health resorts, Dr. Hyman has discovered the seven fundamental causes of obesity. While fad diets have identified one or two of these causes, never before have they all been integrated into a single, simple plan for automatic weight loss. This is the promise of UltraMetabolism.

PLEASE NOTE: When you purchase this title, the accompanying reference material will be available in your My Library section along with the audio.

Ultra Metabolism

This is the first review I have written since my 2 yr membership with Audible. I want to encourage you to take a look at this book!

The book provides the most up to date research in Weight Loss Science and is in line with other credible sources. As an Exercise Physiologist I found the book very useful in helping clients to understand weight loss essentials. The only draw back is that the author often refers to 'CD 4' for text files and quizzes. At first this was a problem but I found I could go to the website and get the guide to accompany the book (which I recommend you do).

The author is enjoyable to listen to and gets to the point. I highly recommend this book if you are having trouble losing weight and want to get good current scientific advice.

CD 4 info is available online

This book is very helpful. Dr. Hyman does a good job of showing why we might be working against ourselves in regard to staying healthy and trim, and how to remedy it. The information on CD 4 is available on the product summary page for this book on Just click the product summary tab above, and look at the very bottom for the "extras" link. There is similar information available at, though the extras link is probably better.

Excellent resource

I have had a problem with fatigue and weight gain since I had my thyroid removed. This addressed both. I enjoyed the entire book and the insight I was able to gain from the quizes. I noticed other reviewers had frustration with accessing the supporting documentation. I found it available at the bottom of the listing and quite easy to download from

Good information here

The information in this book is good, informative info for anyone interested in improving their health. Often the information repeats itself and towards the end, I kept asking myself if I had accidently hit the back button, but in the same breath, I'll also say that Mark's simple steps are burned into my mind and his reasoning for why his guidelines work are clear enough for me to figure out what I should be doing to increase my metabolism. Even if you are already familiar with the world of natural foods and clean living, you will find information in this book that will further your efforts towards healthy living.

Now this makes sense

I liked this book but I wish there were more resources for how to employ the advice given in the book. The author often says "consult your doctor" but truth is, I think my doctor is not quite cutting edge to know about this stuff yet.

Pleasantly surprised

I have always loved butter, salt, Susie Q's and other foods I knew were not good for me. I knew I had to make a change and gradually did, becoming a semi-vegetarian.

After reading this book, following the diet, giving up sugar and all unhealthy oils and basically eating non-processed foods I saw an immediate change in my face and its firmness. Next, I saw a change in how I felt overall. I lost weight (5 lbs) in the first 2 weeks, without any exercise and without trying to. I still haven't really applied the entire book to my regimen yet and can't wait to.

I feel like my body is 10 years younger with this new way of eating. I really recommend this book to everyone, young and old!

Over-the-top excellent information on how best to nourish and sustain our bodies and keep them healthy. Dr. Hyman's narrative is full of energy and promise. This is what's happening now: the knowledge of the how and why of failure of understanding of our food information and diet in contemporary America.
Makes sense.
Makes you want to think carefully about what you eat and what you don't eat!

A keeper

I enjoy this book and plan to keep it on my ipod to listen to for motivation and as a refresher once in a while when I drift off track on my eating and exercise. A great listen!

No Real News

Eat right and exercise. Although the author mentions that there is more to the book; that's the essence. The devil is in the details, however. It is the definition of "eating right" with which we struggle. Downloading the book doesn't get you the "lists" that are necessary to actual follow the good doctor's dietary prescription. You might be better off getting this one at the library or buying it at a discount bookstore so you'll have the details you'll need.

no nonsense factual approach to loosing weight the sound way. Good for someone who has done a bit of reading on the subject of nutrition. Good voice to listen to.
