Many people who want to lose weight seek help from their doctors. How much does the physician's own weight affect the outcome of this interaction? If it appears that the doctor lives a healthy lifestyle, will the patient be more likely to heed his or her advice? The answer is "yes"-with a twist.Are doctors hypocrites if they do not practice what they preach? Is it ethical to say one thing and do another? The modern version of the Hippocratic Oath states "I will prevent disease whenever I can, for prevention is preferable to cure" [1]. One would think that to promote prevention by teaching it demands practicing it, too. Furthermore, the American Medical Association's Code of Ethics asserts that to preserve the quality of their performance, physicians have a responsibility to maintain their health and wellness.... When health or wellness is compromised, so may the safety and effectiveness of the medical care provided.... Physicians whose health or wellness is compromised should take measures to mitigate the problem [2] and that there is an obligation on the part of the medical profession to establish "physician health programs that provide a supportive environment to maintain and restore health and wellness" [2]. This sounds like an ethical call to arms (and legs) for physicians to be healthy and effective role models.
