Dr. Charlene Wolberg, M.D.,Medical Director – Linkfield Obesity Clinic, Johannesburg, RSA
Obesity (from the Latin obesus, “one who has become plump from eating”) first appears in Western medical literature in Thomas Venner’s Via Recta in 1620. However, many centuries before, the ancient physicians had already addressed this subject—a disease that was first reported almost 400 years ago in Western medical literature but whose incidence continues to rise in epidemic proportions.

Obesity is a chronic, multifaceted disease that requires multimodal management. To achieve success, significant life changes need to be made. Dietary manipulation, an increase in physical activity, and behavior modification need to be introduced. The shortcoming of many diet programs is that they focus on only one aspect of the problem without acknowledging that obesity has multiple causes. A holistic, balanced approach is required if one hopes to achieve and maintain success in weight management.

The 5 Skinny Habits puts forward a weight-loss program that addresses dietary, exercise, and behavioral aspects of eating. I like the idea of combining ancient sources with current opinion. The current medical literature and advice is all sound and well researched. The eating plan itself certainly fits all the current recommended guidelines.

One of the misconceptions people have about weight loss is that rapid and large changes are desirable or even possible. The importance of gradual and sustained changes is emphasized in this book. Our medical teachers often remind us that teachings that were once regarded as outdated and obsolete regularly come back into practice when new facts about them are discovered. The understanding of proper nutrition is returning to the principles espoused by Maimonides.

It is my belief that this book will be of great benefit to those who read it and apply its principles appropriately.

The 5 Skinny Habits offers a comprehensive and realistic approach to adopting a healthy lifestyle. Zulberg accurately addresses the need for inner transformation, and development of new perceptions and habits, in achieving long-lasting results. It is fascinating how he creates a parallel between the ancient wisdom of the “Master Physicians” and modern-day science. Using evidence-based practices from multiple disciplines, Zulberg has developed a program that integrates behavioral therapy, cardio/strength training, and sensible dietary practices.

As a dietitian I discourage fad diets, as they are not practical in the long term and have the potential to be counterproductive. The Skinny Habits on the other hand are quite the opposite. They are based on the most current research as supported by the Academy of Nutrition and Dietetics and government initiatives such as the USDA’s Dietary Guidelines for Americans. Zulberg’s work confirms that concepts like increasing fruit and vegetable intake, choosing whole grains over refined products, including lean sources of protein, and drinking a glass of red wine with your meal have been proven effective throughout the ages.

This book is an easy and enjoyable read. I strongly recommend that everyone include a copy ofThe 5 Skinny Habits in their libraries and that they read it over and over again.

Rabbi Abraham J. Twerski, MD, Gateway Rehabilitation Center, Pennsylvania
Maimonides was court physician to the sultan of Egypt. The sultan once asked him, “How can I tell that you are a competent physician? You have never treated me for any illness, because I am healthy.” Maimonides responded, “The reason you have not been ill is because you have followed my instructions. The skill of a physician is to prevent one from becoming ill.” Maimonides describes a course for healthy living and makes the bold claim that whoever adheres to his instructions will not become ill and will die only of old age.

Several years ago, David Zulberg wrote The Life-Transforming Diet, based on the nutritional hygienic and behavioral teachings of the great Middle Age physician, philosopher, and codifier of Torah law, Moses Maimonides. Rather than being a historic relic, it turned out to be a practical modern guide for healthy living.

Zulberg has now expanded his research on Maimonides and classic and contemporary sources on behavior modification, a technique that can be both psychotherapeutic as well as personally pragmatic. The 5 Skinny Habits is a welcome source of guidance for both the professional and the layperson.

R’ Tzvi Kushelevsky – Rosh Yeshiva Heichel Hatorah
I was happy to see Zulberg’s compilation as he has gathered and presented a book in an orderly and beautiful form. Through his hard work and effort, he has simplified the study and understanding of the great Doctor’s writings, Rambam, and to act according to his dictates.
R’ Yisroel Belsky – Rosh Yeshiva Torah Vdaas, OU
Zulberg has made a valuable contribution by the publication of his masterful work, The Life Transforming Diet. He has done an important service in providing a popular setting and scintillating attractiveness for what is usually resisted for its restrictiveness and deprivation.
R’ Shmuel Kamentsky – Rosh Yeshiva Philadelphia
Zulberg has made a good contribution, as we still live, exist and rely upon the words of Rambam.
R’ Dovid Goldwasser – Eating disorder expert
Having had the privilege, for the past decade, of working with people suffering from eating disorders, it is a particular ‘simcha’ for me to see that Zulberg has put out a monumental work entitled The Life Transforming Diet.
R’ Berel Wein – Expert on Jewish history
The wisdom of Maimonides has stood the test of time and his good advice on exercise, diet and sleep are well accepted by doctors, nutritionists and health experts today. Zulberg’s book makes it simple for anyone to regulate life habits in a healthful and positive fashion. It will be a great addition to one’s library and way of life.
R’ Leib Kelemen – Neve Yerushelaim
Zulberg has performed an invaluable service by assembling a plan for healthy living that is consistent both with the advice of our sages and the findings of modern medicine. His work is unique among diet/exercise guides in its reasonable tone and moderate approach.
Tova Singer, MS, RD, CDN—New York, USA
Diet philosophies are a dime a dozen. Each belief promises to help participants lose weight fast, with great ease, all the while claiming to be the only true, sustainable diet.

In my 10-plus years as a dietitian I have seen and heard them all. However, I have never come across one that is as universally successful as the 5 Skinny Habits. David Zulberg’s approach is both unique and time tested. Ancient wisdom may have been limited in its resources, but that’s what differentiates this diet from all the fad diets. There is no fad or trend here, just sound emotional, physical, and nutritional advice.

While many of the newer diet programs focus on our access to exotic food types or exercise paraphernalia, the 5 Skinny Habits focus on the right mind-set to sustain the right eating habits with a consistent exercise routine. Written in simple, laymen’s terms, it is an easy plan to follow and more importantly manageable to maintain for the long term. If more health-conscious individuals would follow this logical dietary routine, the prevalence of obesity, sickness, and disease would surely lessen, and a greater quality of life of overall health would ensue.

Rabbi Akiva Tatz, MD, England
This book provides a detailed practical program for maintaining an excellent nutritional program in the long term. This program will help to control weight and improve health, both physical and psychological. As with anything worthwhile, effort will be required, but with the insights and advice contained here the path will be easier, and indeed should be enjoyable.

The research in this book is exemplary. The sources used for the exercise guidelines—the American College of Sports Medicine and the Journal of the American Medical Association—are the most accurate and well recognized as leaders in the sports medicine and wellness industry.

At FIFA Medical Conference, Professor Karim Kahn spoke about how inactivity is killing the American population, as it leads to chronic diseases and obesity. The 5 Skinny Habits cardio advice and eight-strengthening-exercises routine is a total-body workout, which can be mastered in the comfort of your own home.

Most diets are expensive and still lead back to old bad habits. This program teaches how to implement small and practical steps. My patients love the program, as they experience results in a defined time frame. I recommend this book not only to people who want a permanent solution but also to professionals in the field.

Cindy. M, R.D., USA
As a registered dietitian, I was very excited to read The 5 Skinny Habits. Merging ancient wisdom and current-day research, David Zulberg’s 5 Skinny Habits is profound in its simplicity. Simple, because it goes back to basic, fundamental principles that have been with us from the earliest days of recorded medicine. Profound, because it recognizes that the internal motivation to get healthy must be present in an individual before change can happen. Once the motivation is there, the approach Zulberg lays out is well balanced, gradual, manageable, adaptable, and sustainable. He is sympathetic toward the inevitable setbacks and offers clear guidelines to get back on track. This book is so much more than a weight-loss plan—it is a life-transformation plan.
Danielle Jacobs, Certified Personal Trainer, NY, USA
As a certified professional trainer for the past 15 years in the field of fitness including spin, boot camp, hip-hop, and total-body conditioning . . . I am always excited when I see a new member at the gym that is enthusiastic about starting an exercise program.

Unfortunately many times this passion wanes due to schedule, failure to see immediate results, life’s challenges, and sometimes, simple laziness. At the core, people often fail to build a solid exercise habit. They are too anxious to lose weight or have unrealistic expectations. The truth is, maintaining an exercise program requires patience, perseverance, and implementation at the right pace.

I love the 5 Skinny Habits exercise routine because it offers so many different options with solid results, if it is followed correctly. It is suitable for any age or gender. Most importantly, it builds an exercise habit at the right pace. It is remarkable to read the nutritional and fitness insights through the centuries. I would definitely recommend this well-balanced and practical exercise program!
