She is certified both through the American Board of Internal Medicine and American Board of Obesity Medicine, completing comprehensive training and rigorous testing in each medical specialty.

What is Obesity Medicine? Obesity Medicine is the field of medicine dedicated to the care of patients who are overweight and obese. Doctors who are obesity medicine specialists use comprehensive, scientific, and an individualized approach comprised of nutrition, physical activity, behavioral therapy and medication to help patients lose weight and achieve overall better health. Board certified obesity medicine specialists are clinical experts in weight loss and weight management.

Dr. Shah is passionate about teaching people how food is at the cornerstone of our health. After treating thousands of patients in hospitals she realized that most people didn’t have the basic foundational knowledge to take care of their health. Medications are simply a band-aide to our problems, not the cure. She teaches people that:

The cure (and the problem) lies in our food.

Our food choices can create chronic disease or prevent and reverse them. She teaches people that food is medicine – we can reverse many medical diseases like diabetes, hypertension, high cholesterol problems by losing weight and/or understanding how food impacts our health.
