Choose between public Speaking, workshops & Support groups


Public Speaking

Book David to talk at your company or institution.

Talks are done via Zoom or at the facility. You can request one lecture on any topic related to health, fitness, mindfulness, self-awareness or habit formation. David also does workshops for companies and institutions.


Support Groups

The private small support groups are for people looking for more personal attention, tracking progress and interaction. You may have read the books or done the workshops but now you want to discuss, interact and share your experience and insights with the author and a support group.

Charts and Recipes included.


Each week will introduce a new principle and habit with its practical implementation. This workshop includes the principles from David’s books, as well as extensive research relating to managing feelings and altering thinking patterns that have not been published yet.

I wanted to thank you wholeheartedly for a weight-loss system that has helped me to create a healthier self. To date, I have lost 95 pounds, and I hope to continue applying these positive habits to my daily life. I still follow your program and exercise regularly.

I have been following the principles of the 5 Skinny Habits and I have lost 40 pounds. My type 2 diabetes is under control, and I am no longer on medication for it. My lab values show that I am healthier than I have been in years. This program really works and helps me focus on how to change my life gradually. It has been a great blessing to me. Thank you.
Type 2 Diabetes

Kevin, Ohio, LA

Upon being laid off from a very stressful job last year, I decided not to be defeated emotionally or physically by the upheaval. So I embarked on your regimen of exercise, healthy eating, and positive thinking. As a result, I lost 40 pounds. In addition, my cholesterol went down from a whopping 290 to 140! I feel both emotionally and physically better than I ever felt before.

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.

The Life Transforming Diet 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.

Dr. Charlene Wolberg, M.D.

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.
