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. This program addresses dietary, exercise, and behavioral aspects of eating.

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. May God reward your efforts and may we merit living a healthy life that enhances our purpose in every area of life.
Lost 95 Pounds

What makes this diet different from all the other diets I have endured? I think it is the brilliance of the subconscious habit formation process to form new positive habits in order to fight the old, established ones. I didn’t have to eliminate everything in one go. The emphasis is not on “willpower” alone. The focus is rather on the gradual development of good habits. It is so clever to quietly cultivate positive habits and to help them grow until they are big enough and strong enough to “fizzle out” the former monster “masters.” Becoming aware of the ability of my “creative” mind to predominate my decisions has been very enlightening, and I have never been so calm about food and food choices. I don’t really feel like any of my old temptations, and I’m not waiting for the opportunity to “break out.” I lost over 40 pounds and have not felt deprived or trapped—in fact, I feel energized—and most importantly it took me 6 months to do it!

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.

Over time, I started to develop unhealthy eating habits, eating lots of cheap, refined sugar products and refined wheat foods. I had become accustomed to my unhealthy eating habits and maintained them for the 9 months. That is around the time I went for a physical and came in at over 30 pounds more than my baseline. It’s also around the time that I needed to renew my passport ahead of a business trip. Of course I had seen myself every day in the mirror, but for some reason, when I took one look at my passport photo, the reality hit me hard that I needed to do something before my weight got any more out of control. As I was browsing one day, I came across this program. I went home and “ate it up.” That was the turning point. I followed all the instructions, and within a few months I lost over 30 pounds and have kept it off since. At the same time, my wife joined the plan with me and lost 25 pounds as well in just a few months, and has continued to now, having lost a total of 40 pounds! We now feel fit and healthy and could not have done it without these principles. Thank you!!
Lost more than 30 pounds

Steve, Brooklyn, USA

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.

One of the main keys to success is to follow the program carefully and commit to following the guidelines for at least 2 months, no exceptions. We were not even trying to lose weight, because we didn’t think we could. . . . But week after week as the pounds came off, we realized the simplicity and effectiveness of these principles. My husband is in a wheelchair, so losing any weight was a real challenge. He put on 60 pounds in about a year but successfully took it off in about a year and a half using your guidelines. I had put on 30 pounds and took off almost 40 pounds in the same period of time. We have totally changed how we think of food. It’s now hard to go off the eating plan. When we have coffee in our local mall and see people buying pastries, it gives us a sick feeling . . . all that white flour, white sugar, trans fat . . . and you can see what happens to the people who eat it . . . they are turning into pastries themselves. Eating properly can make one’s connection to God stronger, affecting all aspects of one’s life. Much success to all who commit to following the guidelines. Don’t try . . . do it.
