If we accept the idea that Nature is near perfect and has designed a brilliant and awe-inspiring product—our bodies—then we have to pause and wonder why half of Americans are overweight and 20 percent are obese. That doesn’t sound like anything close to perfect! It would seem that after 3.5 million years of evolutionary refinement, the apparatus that regulates our food intake and impacts our very survival is flawed for half the people in this country. What could be the problem?
If we put the wrong fuel in any machine, fuel that wasn’t designed for it, either it is not going to run, or it is not going to run very well, with “well” the operative word when it comes to our fuel choice.
We have over 1,800 diet books in print and they haven’t made a dent in America’s obesity. The truth is, they never well, unless we stack them on the floor for aerobic stair-stepping or walk them back to the library to burn off calories.
