I often talk with patients about the distorted images about our bodies that industry and the media widely propagate. It’s hard to live in our society and yet avoid thinking that we all need to look like Brad Pitt or Angelina Jolie in order to be attractive.

This is particularly true for women: I recently read research suggesting that only 12% of U.S. women are very satisfied with their attractiveness and only 2% describe themselves as beautiful.

In many discussions I have with patients, we ultimately come to the conclusion that the only people who look like Brad Pitt or Angelina Jolie are…Brad Pitt and Angelina Jolie. And that we don’t have to look like them to be healthy, happy, or attractive.

But, as the video below suggests, not even Brad or Angelina actually look like the unattainable, air-brushed, make’d-up versions that we see on TV, billboards, and magazines!

I just found this video, but you may have seen it back in 2006 when it was created as part of a marketing push by Dove called the Campaign for Real Beauty. While their goal was to sell Dove products, it is a testament to them that they shed some light on this (and a shrewd marketing campaign).

I’d like to stop this post now, but can’t help but add one more thing: if you now go to www.CampaignForRealBeauty.com, you get to a website owned by Medifast, the commercial diet company, which sells the typical “weight loss at all costs” message (and products).


Later today, researchers from Yale University will present an important new study at this year’s American Public Health Association conference. Their research study shows that food companies continue to aggressively market sugary drinks and other junk foods to young children, despite prior pledges to improve child-directed advertising.

Nearly 600 products from 14 beverage companies were studied. Few of their beverages were nutritionally sound, though many presented misleading health claims – such as claiming “all-natural” or “high in antioxidants” on a high-calorie soda or “low sodium” on drinks that are essentially all sugar.

From 2008-2010, kids’ exposure to ads for sodas doubled, and their marketing has become particularly aimed at low-income and minority populations.

Decades of social science research has shown that marketing strongly affects our preferences and choices. Kids are particularly vulnerable to marketing; they are essentially “sitting ducks” for advertisers.

A recent study that I’ve repeatedly discussed showed that marketing can essentially define what kids like to eat. When kids see a licensed character (such as Shrek or SpongeBob) on a packaged food, they say that the food tastes better than the exact same food packaged without the character. All else being equal, in a “taste test” between the exact same food in a similar packaging, but one of the packages simply has a picture of a fun character on it, kids say that the one with the character tastes better (and, of course, they are more likely to choose it). I’ve spoken and blogged about this.

This is particularly important because we live in a new world in which chronic, often nutrition-related, health problems are the most common causes of disease and death in the U.S. This is a stark change from just a few decades ago, when acute diseases, such as infections like tuberculosis, were the biggest killers.

We would never let our kids be attacked by advertisements for germ-infested products that would make them sick or tobacco products that would give them cancer – yet this is what’s happening right now. Sugary drinks and other junk foods contribute to the unhealthy eating and obesity that is killing as many Americans as tobacco.

And this study shows that things are getting worse, despite the pledges of many food and beverage companies to regulate their advertising to young kids.


HHS officials released their end-of-decade assessment of progress made toward the Health People 2010 goals. If you’re not familiar with Healthy People, see here.

This public health program aims to identify the nation’s health improvement priorities, and provide measurable objectives and engage multiple sectors and stakeholders toward achieving these priorities. It’s redone every 10 years as a set of public health goals for the coming decade.

The final review was positive in many ways. Americans are living longer. Fewer are dying from cancers, including breast, colon, and prostate. And we continue to make progress in the fight against tobacco.

One area that seems futile to many is the obesity epidemic. But as I’ve written previously, and as I discussed in an article published on WebMD today (and pasted below), I believe we’ve actually taken many important steps forward that set the stage for a productive decade ahead.  [Read More…]


Got a nice email from one of my medical students today. Here is a brief piece:

“…Teaching medical students about obesity is so important and it would nicely fit into a semester-long course. Instead of wasting endless hours on learning about the biopsychosocial model as a vague concept, we could actually spend time learning about direct approaches to specific problems that all physicians face (depression, obesity, diabetes, heart disease, etc.) Instead of spending one lecture on a multitude of topics we should spend most of our time on the most common pathologies/illnesses. You’re advice to me to “not get lost in the minutiae of medical school” is so important because medical school is all about the minutiae and it’s easy to forget that there is a civilization beyond the medical school/hospital doors where most of our learning will actually take place. It’s ironic that physicians often say “don’t look for zebras” when the first 2 years of med school are all about the zebras (rare disorders). I’m not sure what has to happen to shift the focus; it’s something I need to look into.”

It can’t be easy putting together a 4-year medical school curriculum; there’s certainly lots of stuff to cram into young med students’ brains in a short time. But we really need to rethink the process. We waste a lot of time on things that no one will remember, let alone appreciate, and we fail to teach the stuff that really matters. Like relating to patients, building relationships, and helping guide and partner with patients on difficult behavior changes and health and life choices…not to mention some real education and guidance in how to work with patients who have obesity and other chronic diseases.


This article was published in The Huffington Post on September 23, 2011.

My initial reaction to last week’s announcement of a new Michigan policy to track kids’ weight was emotional and negative. Indeed, so many recently publicized policies and prescriptions regarding weight seem to be uninformed and often stigmatizing toward people who have obesity. For example, there have been calls for taxes levied against people with obesity and proposed laws against serving food to people with obesity, not to mention doctors who systematically refuse to treat patients who are heavy.

So when I heard that Gov. Rick Snyder would mandate doctors to report their patients body mass index (BMI), I jumped to the conclusion that this was yet another example of punishing people for their weight in a society that strongly pushes overeating and weight gain.

But let me explain why this is a good public health measure: It’s a core, essential step in our approach to the childhood obesity epidemic. That is, as long as it’s done right. [Read More…]


Health reform is an ideal platform to make progress in how we support the treatment and prevention of obesity and related health problems.

My colleague, Christine Ferguson, wrote a Huffington Post article describing the recommendations we submitted to the Department of Health and Human Services (HHS) Secretary Kathleen Sebelius regarding the inclusion of obesity services in the essential benefits package for health reform.

Our position:

No obesity services should be summarily excluded from the EHB package and obesity should be given the same consideration as any other health condition, particularly with regard to coverage and cost-sharing.


The Good News About Obesity

September 16, 2011

Published in The Huffington Post on September 18, 2011.

The CDC’s recent report of the top 10 Public Health Achievements of the past decade overlooked one of the most important: progress in the fight against obesity.

I bet you’re surprised to read this. While there are many “no brainers” on the CDC’s list, such as tobacco control, motor vehicle safety, and heart disease improvements, scary statistics and media reports suggest that we’re losing the obesity fight.

To be sure, obesity rates only increased over the past decade, continuing the epidemic rise that has progressed over the past half-century. But hidden underneath the scary statistics is quite a bit of good news:  [Read More…]


Great little article by film director Kevin Smith in this week’s Newsweek:

I tried to get on a Southwest Airlines flight last year, and it didn’t go too well. I had just done a podcast for the International Bear Rendezvous, which was a big gay get-together for dudes who look like me. It was a fantastic feeling because I was in a room with people who for the first time were sexualizing me. I boarded the plane, and the stewardess showed me to the only available seat on this flight. It was between two petite women. Then a lady from the front desk told me to get off because there were “safety issues.” And I said, “Ma’am, please don’t make me leave this plane because you’re saying I’m too fat.” After I left, I tweeted about what happened. My mistake was thinking the story was going to be that I caught a lousy corporation that f–ks with people. But instead the story became “fat guy in a little chair.”

I was at the top of Google News for three days, and all the articles said I was fat. It was horrible. It was like being publicly naked. [Read More…]


This was published in The Huffington Post on August 23, 2011.

Last week, the 11th Circuit Court of Appeals declared the individual mandate of the Affordable Care Act (ACA) invalid, and now some people are changing their bets about whether the Supreme Court will put the issue on its docket for next session.

But what no one is talking about is the curious bind this opinion puts on the 26 state plaintiffs, who brought the suit the 11th Circuit reviewed, and especially Governor — now Republican Presidential candidate — Rick Perry. The phrase that rings the warning bell is: “Numerous Supreme Court decisions have identified the regulation of health matters as a core facet of a state’s police powers.”

You read that right: A state’s police powers. [Read More…]

Fat is bad?!

August 8, 2011

Just got an email from one of my medical students, who let me know about an NPR article regarding weight bias and stereotypes.  See below…

Hi Dr. Kahan,

I am sure you already know about this, but on the off chance your summer has been too busy, I thought I’d send it your way. This is a refreshing perspective for the (somewhat) mainstream media!


I was eating dinner with some college friends last night, most of whom are on diets because ‘fat is bad’ and I was really excited to share with them the perspective you gave us. Not sure I really convinced anyone, but its a start right?

Hope you and your family are having a great summer!
