What You Need to Know About Weight Loss

When most people decide they need weight loss, it is because their current diet is so bad and unstructured, they need help.  At that point, almost any dietary restriction and structure will help them lose weight and cause them to fall in love with their chosen diet.  But, many people pick diets that are not practical to maintain causing the weight to return.  This causes many people to give up on weight loss.

Dr. Barrett has designed a diet that is not only self-sustainable in the long term, but it will also help you manage stress making it a win : win situation.  Dr. Barrett’s diet includes a strategic use of minimal carbohydrate intake along with adequate protein and healthy fat consumption combined with moderate intermittent fasting.  Dr. Barrett will bench mark your current weight, body mass index, body fat and muscle percentage, and resting metabolism.  Dr. Barrett’s diet is designed to lose body fat while maintaining lean muscle matter.  Dr. Barrett combines the science of biochemistry of Western Medicine with the 2000 years wisdom of Eastern Medicine for a natural, safe, effective and self-sustainable method of weight loss for optimal health, wellness and longevity.

Patient Testimonials For Weight Loss

Gregory, Age 54: To Whom It May Concern: I was 6′ 3″ and weighed 300 pounds. As a former athlete, I used to be in decent shape. Then middle age and a sedentary lifestyle added 80 pounds too much to my large frame. Failing at every diet that I had tried, I remained overweight for over 10 years. Then I had a heart attack. Obviously, a change in lifestyle was needed. Then I met Dr. John Barrett and he introduced me to his weight control system. In 6 weeks I lost 16.5 pounds while not having hunger pains nor any other diet related problems. Dr. Barrett explains to you so well, that he in fact teaches you a lifestyle so that you can control your diet. Thanks to him, I now know how to eat properly for weight control.Thanks a million John. Sincerely, Gregory”
