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.

What we need to do now is recognize that it is the sum total of human ingenuity that is responsible for the epidemics of chronic disease. Throughout most of human history, calories were scarce and hard to get, and physical activity unavoidable. Calories are now abundant, and physical activity is hard to get. We took an unstable, uncertain food supply and fixed it. What now passes as exercise and requires specialized footwear used to be called "survival." You had to do it. Now you never have to do it. We solved it too well. Now we don't need our muscles for anything.

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.

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.

My view of chronic disease prevention of fighting epidemic obesity and diabetes, of turning the tide, is that it is the job of professionals to pave the way and to cultivate the will; to stir people up so that they understand the stakes, so that they recognize that adult onset diabetes stalking children is a clear and omnipresent danger. The wolves are at the door. You must defend hearth and home. And here are the means to do it: we must provide programs, policies, tools and resources so that everybody can do the job.

We are facing a flood tide of factors into our daily lives and the lives of our children that conspire against weight control, and for that matter, health, any single policy or program we use to turn the tide is like a single sandbag. You put down the sandbag on the banks of the river. You could ask the question: Have we held back the flood? A sandbag isn't designed to hold back the flood. A sandbag is designed to be part of a levy to hold back the flood. It doesn't matter if it's a good sandbag, maybe a perfectly good sandbag. By itself it can't fix the problem.
