While you should trust their advice on certain matters, it's also important to understand the boundaries of their training, and when you should seek outside help. I grew up obese despite the fact that both my parents were medical doctors, and fit ones at that. The few conversations we had about my weight were essentially lectures on moderation (or simply "eat less, move more"). I always figured the lack of intervention was probably because they assumed I'd grow out of the chub. Besides, it can't be easy for someone to dual as parent and diet coach. Fast forward two decades, and the story is completely different. My father is now overweight and pops countless (medical) pills for breakfast. He doesn't know the first thing about losing weight, nor does he care to learn. Contrastingly, my mother is in great shape, thanks to becoming an avid consumer of fitness information following my own transformation. Looking back, I now know that their silence wasn't because they were hesitant or unwilling to help me lose weight. It was because they had no clue how to help me lose weight. My parents are just n=2, but in my coaching experience, many clients have reported a similar gap in their own GP's knowledge. Sure, their doctor can tell them when to lose weight, but dispense poor advice to help them achieve it. This is unsurprising. What Doctors Know: Disease vs. Health Most doctors spend at least 11 years in school: four years in an undergraduate program, four years in medical school, and at least three years in residency (depending on chosen area of expertise). Basically, doctors learn a whole lot about a whole bunch of stuff, for a long time. But in all those years, and all those textbooks, very little of that is about nutrition—the biggest factor in weight loss, and debatably one of the most important factors for overall health. Of the 40,000 hours that doctors spend on training, typically only 19 of those are devoted to studying nutrition. According to the Chicago Tribune, this number is steadily decreasing: On average, doctors receive 19 hours of total nutrition education in medical school; in 2004 the average was 22.3 hours, according to the study, conducted as part of the Nutrition in Medicine project at UNC. In 2009, 27 percent of the schools met the minimum standard of nutrition training, compared with 38 percent in 2004. As such, it shouldn't be surprising that a study from The Journal of the American College of Nutrition shows that only 14% of internal medicine interns feel they can adequately talk to their patients about nutrition, while 94% feel it's their responsibility to do so. Yet, if Dr. Oz's popularity ratings are any indication, society still considers doctors to be weight loss authorities. To be clear, this is a systematic failing of the medical educational system, and not the fault of our doctors. Between seeing patients and fixing them—something that they are incredibly knowledgeable about—there's not a lot of time to make up for their educational shortcomings. Still, it seems silly to only look to medicine to reduce incidence of disease, when dietary intervention may have prevented some of these in the first place. The Problem with Defaulting to Doctors for Nutritional Advice The nutrition and fitness industry is full of shi—err...incredibly confusing, which is in no way helped by the apparent paralysis of relevant regulatory parties. Case in point: despite decades of outcry from the scientific community, the FDA is only now relaxing its message on the dangers of dietary cholesterol. With conflicting information abound, people deal with confusion in different ways. Some are autodidacts, or self-learners, who read voraciously until they can navigate through the noise. Most people, however, naturally default to someone they trust to tell them what to do. Human beings are subject to something called bounded rationality—the idea that, in the face of complexity, humans sacrifice calculating the purely rational choice by making mental shortcuts. For most people, doctors are the gatekeepers of health information. They know doctors are educated in their profession, and generally trustworthy. Therefore, it seemingly follows that a doctor's health advice must be reliable. The problem is that too many people think that "curing disease" is the same thing as "preventing disease." In reality, these are two completely different areas of expertise. As my friend Dr. Joseph Lightfoot once told me: "In medical school, I learned about disease, but I did not learn about health." In spite of this, it's hard to imagine a doctor's typical nutritional recommendations could be harmful, after all how dangerous could an abundance of cruciferous vegetables be? However, the utility of their advice is undermined by one of medicine's most basic tenets: "First do no harm." In other words, they must make sure that any treatment does not make a patient's situation worse. For nutrition, this often translates into stock-standard dietary advice. For example, let's say a doctor is faced with the choice of giving a recommendation that's in line with the status quo, such as limiting sodium, or going against the grain by saying that you shouldn't worry about salt intake. In the doctor's eyes, which is more likely to "do no harm?" Most doctors would avoid the controversy and just tell their patient to limit their salt intake, because that's what everyone has always said. Their assumption is that advice "does no harm." The problem is that it does do harm. It increases their patient's chances of failure. Quite simply, research shows that the best diet is one you can stick to. By creating false restrictions and limiting choice, you state that there is only one path for success (the doctor's)—a low sodium, low saturated fat, low cholesterol, alcohol-free one—when in reality there are many. According to obesity specialist and frequent Lifehacker contributor Dr. Spencer Nadolsky: Unless trained through ABOM (American Board of Obesity Medicine), ABPNS (American Board of Physician Nutrition Specialists ), or similar training/experience, the typical doctor isn't as well equipped to help with dietary guidance. This doesn't mean the doctor is bad, it just means it wasn't in their training. They may be able to refer you to the right place and certainly they can help in regards to switching meds around in case any are associated with weight gain. In reality, doctors who don't have a solid nutritional foundation probably shouldn't be implementing a diet intervention at all. How to Find a Doctor That Can Help You Of course there are plenty of doctors with abundant nutritional knowledge, like Dr. Nadolsky or Dr. Yoni Freedhoff, another frequent Vitals contributor. In fact, because of their multi-domain expertise, these doctors have unique insights around preventative health and disease that few others possess. The danger, however, is that assuming that all medical doctors have this same expertise. Here's how to find out if your doctor can help you with your own nutrition and fitness endeavors: Research the latest evidence on topics such as saturated fat, protein intake, and dietary cholesterol. Examine.com's FAQ is a good place to start. Ask your doctor questions about these topics, such as "Is a high protein diet right for me?" or "Are eggs bad for my health?" If they default to outdated wisdom without batting an eyelash, then you may want to seek nutritional guidance elsewhere. Pay close attention to whether or not their advice is specific and actionable. Are their recommendations vague, such as "eat healthy" and "do things in moderation?" or do they go into specific recommendations, such as "keep a food journal and track calories." Look at other credentials other than the "Dr." in front of their name. You can use this handy PDF to search for a physician's certifications by any state. Are they trained by the American Board of Obesity Medicine, the American Board of Physician Nutrition Specialists, or something similar? Be realistic about how well you get along with your doctor. Knowledge isn't everything. Your doctor can be the most knowledgeable in the world, but their advice can backfire if you feel that they are overly judgmental or lack empathy. At the end of the day, the onus is on you to make sure that you have the resources you need in order to get (or stay) healthy and fit. Stay as informed as you can on the latest nutritional research. Don't expect your doctor's knowledge about medicine to apply to other domains. After all—like you—they are only human.
