About Us

Studies have shown that the average physician in the United States receives little or no education in the field of obesity medicine. W8MD medical weight loss centers of America an effort to help improve awareness of the complex factors that lead to weight gain, instead of the usual approach of "blaming the patient" for weight gain instead of understanding the true causes of weight gain.

Why Blaming the Victim For Obesity Does Not Help!

While many people tend to blame the "victim" including the patients themselves that take the blame on themselves for being obese or overweight, we believe that obesity is a chronic medical condition like hypertension or diabetes and needs a physician well versed in the field of obesity medicine to help treat this condition, and reduce the risks associated with it.

Not another fad diet - based on true science and art of obesity medicine

Unlike the many fad diets, W8MD medical weight loss centers of America's weight loss physicians are specially educated in the new field of obesity medicine. Our experienced and trained weight loss physicians understand that obesity is a medical condition with many contributing factors, and not just overeating on the part of the patient.  With their experience and education, our weight loss physicians partner with each patient to design a custom weight loss plan that is right for them.



  • We will not blame patients
  • We understand the complex causes
  • Our physicians are well trained
  • Most centers accept insurance
  • Evidence based weight loss*
  • Meal replacement supplements

What makes W8MD Medical Weight Loss Centers different?

Our weight loss program is unique in many ways. First, our our physicians are very experienced having helped thousands of patients to successfully lose weight.

Second, W8MD weight loss physicians understand the true factors that lead to weight gain including hormonal(insulin resistance), social, environmental and genetic factors and work with each patient individually to help design a customized weight loss plan that works for them.

Third, most of the W8MD medical weight loss centers accept health insurance for the weight loss physician visits unlike the many other weight loss programs.

Fourth, most W8MD medical weight loss centers also address any underlying sleep problems that go hand in hand with weight gain. In fact, recent research conclusively established the bidirectional relation ship between sleep problems and weight gain.

 Central distribution of weight and metabolic risk

W8MD understands that central adiposity with belly fat poses more health risk even in those patients that might have relatively normal or near normal body mass index and designs a customized strategy for each patient. Affecting one in three Americans, metabolic syndrome plays a key role in increasing the inflammation in the body and contributes significantly to the metabolic risk associated with this condition including increased risk of cardiovascular diseases, diabetes, and even cancer.

Obesity Medicine and W8MD Physicians 

While 70 percent of the population of the United States are either overweight or obese, physicians typically do not get much education in nutrition and weight control. According to research, 94% of the physicians get little to no education in Nutrition. Lack of proper bariatric medicine training for healthcare providers contributes to our health care system's inability to help their patients lose weight successfully. As well trained and experienced bariatric/obesity medicine physicians, W8MD's are uniquely qualified to treat obesity and the over 50 associated conditions.
