Tools for Success

We have a Signature Patient Website to help you and to keep track of your weight loss progress. Also part of our program is the Tanita scale, which measures your body composition and The ReeVue™ metabolic test which measures resting energy expenditure.

Signature Products

Our Signature Supplements and Products contain only the highest-quality ingredients and are specifically designed with proprietary formulations that supply the nutrients you need to help you achieve and maintain your ideal weight.

Extensive Research

Health problems, such as diabetes and cardiovascular disease, require the specialized care of a healthcare professional. This is why one- size-fits-all approaches to weight loss and weight maintenance often don’t result in long-term success. (Jensen et al., 2013).

Amazing Support

Our program is based on weekly visits where we do body composition analysis, complete medical exam (including blood panel and EKG) and even more, we educate our patients about nutrition and fitness.

Physician Supervised

We are a physician supervised weight loss program where we offer a balance of education, appetite management and exercise activity to lose weight. We teach you strategies to keep weight off using real food.

Proven Success†

Over 3 million pounds lost since 2006. Our patients are thrilled to tell the story about their weight loss journey. Find inspiration and motivation to join them on the path from before to after here!


Overeating doesn’t make you fat.
Rather, it’s an excess of high glycemic foods like sugar and refined grains.


† Results may vary from patient to patient. Rapid weight loss may be associated with certain medical conditions and should only be considered by those who are medically appropriate.
