Obesity has become an epidemic. Over 55% American adults are overweight. We have always regarded this as a self-imposed condition, blaming gluttony, lack of discipline, or a sedentary lifestyle. But as a number of recent books have pointed out, it is not how we eat, but what we eat that causes obesity. What we are eating is a normal American diet.
Why stop obesity? Isn't it okay to be fat, as long as you are fit? The answer is that the health consequences of this epidemic are not due to being fat, per se, but eating this diet. Our normal American diet is leading to increases in diabetes, hypertension, high cholesterol, fatty liver disease, and possibly some cancers, in addition to obesity.
Yes, eating the American diet is making us fat and sick, and shortening our lives. It has become our most pressing public health problem. Let's consider what is wrong with the modern American diet, and what we can do to change it. And we'll see how energy independence may contribute to the solution.
What is wrong with the modern American diet
Years ago, you ate what you liked, stopped when you were satisfied, and didn't get fat. This is how our biology is put together in an ideal world. Nowadays you must continuously count calories, exercise, and diet merely to maintain your weight. The biologic mechanisms that prevented us from overeating have not changed. What has changed is the food.
We may think we are eating the same food that we always have, but in fact we are not. Our diet has changed more in the last generation than it has since we first climbed out of the trees and became omnivores! Our biology is optimized to subsist on a diet containing a wide variety of foods, but it doesn't deal well with our current diet because we are no longer eating food. Up to 70% of what we now eat is processed food or, as I prefer to call it, synthetic food.
