We have a society that monumentally conspires against the pursuit of health. We have wave after wave of labor-saving technology that says don't ever use your muscles for anything, along with messages that you should be more physically active. We have, every year, the introduction of hundreds, if not thousands, of new highly processed foods, the majority of which glow in the dark. At the same time we're telling people: eat foods closer to nature. We have schools where we teach children to sit still all day long so they can become adults we can't get off couches with crowbars.

There is one thing that very reliably try to trumps the food supply and that is food demand. At the end of the day, the business of business is business and they are just trying to keep the customers satisfied, it depends what we want. The problem in our current mess is we want all the wrong stuff. Why do we want the wrong stuff? Because taste buds are very malleable little fellows. They learn to like what they know. We're bathing our taste buds in too much sugar, too much salt, too much processed food all day long. That's what they know and crave.

Balanced, sensible nutrition: eat food, not too much, mostly plants, a healthy diet ala Michael Pollan, modern physical activity on a daily basis, modest weight loss - translated into a 58% reduction in the occurrence of diabetes. A clear indication of the power of lifestyle over health. The challenge now is the development of the community-based programs that will translate what we learned in the diabetes prevention program and put it to work in every town in America.

We are creatures. We have a link with a native habitat just like every other species. Throughout most of human history, physical activity was unavoidable, calories were scarce and hard to get. In the modern era, calories are unavoidable, physical activity is scare and hard to get. The traits that allowed our ancestors to survive, and let's face it, the survival of our ancestors is the reason that we're here because the people who don't survive and make very crummy ancestors, are our traits. But they're very much at odds with the modern environment.

The metaphor I routinely use is polar bears in the Sahara desert. You take creatures adapted to the cold and put them in the heat, the very traits that allow them to survive in one environment will conspire against them in the other. We are polar bears in the Sahara with one important distinction: we are smarter than the average bear. Once we identify the nature of the problem, we can think our way out of it. But it begins by acknowledging you didn't fail because you couldn't succeed. Because you didn't even know what the scope of the problem was. It's not your fault.

I naturally gravitate toward the big picture which isn't necessarily advantageous when you go on to a career in research because successful researchers usually choose a pretty narrow channel. So having tunnel vision actually helps you stay where you are supposed to stay. The big picture in medical care was looking at the underlying causes of all of this pathology. I really wanted to do something about that and play a meaningful role in changing the trajectory of people's lives and their health and by changing their health, changing the quality of their lives.

Color, rather than shape, is more closely related to emotion.
