YOUR GENES ARE RUNNING THE SHOW

If you're anything like me, I know you're champing at the bit to get going on Diet Evolution, but hold your horses. I've found that most of us can stick to a program only if we understand how and why we got to our present state of affairs. The next four chapters will do just that.

You can thank Mom and Dad for your beautiful baby blues, as well as your hair color, height, and build. All these traits were encoded in copies of their genes—half of them her's, the other half his—that now reside in your body. Any children you have will in turn have copies of half of your genes and half of your partner's, and so on through generations to come. Determining our appearance and myriad other characteristics is just one way in which our genes rule our lives. As you'll soon learn, they also play a more clandestine role.

The answer to why almost all attempts to lose weight fail resides in your genes and the lies they've been feeding you. Once you understand how genes behave, and how their behavior controls your behavior, you'll be rewarded with an understanding of how you can lose those extra pounds, regain your health and vitality, and set the stage for a long, vigorous life. I'm sure you have heard that if you feed your genes right, all your health problems will disappear. But here you are stuck in the same old rut. I'm going to prove to you that you're in poor health and overweight because you're feeding your genes exactly what they want. Let me assure you, your genes are using you for their health and longevity, not yours. In fact, your longevity stands in their way. So sit back, open your mind, and be willing to suspend everything you've ever known about yourself. But first let's get down to basics.

GENES AS MICROCOMPUTERS

I've found that it helps to think of genes as tiny computer programs. On your computer, the letter A, for example, is "coded" as 1000001. Whenever I strike A on the keyboard, this code of 0's and 1's tells my computer to make an A appear on the screen. Think of your body as a computer and your genes as its operating system. Genes are pieces of information composed of hundreds or even thousands of sugars and proteins arranged in sequences that "spell out" the process the gene wants a cell to perform. They contain all the information needed to tell each cell what to do, but in this case, the keys that turn genes on or off are circulating hormones, neurotransmitters, and numerous other information carriers, particularly compounds in food. To continue the computer metaphor, these codes work much as typing an Internet address into your Web browser "tells" it what information you want.

Your genes are totally dependent on your body to protect them and house them until a new computer, in the form of your offspring, can take on these tasks. We need our genes as much as they need us: your body only works when its operating system—your genes—tells it what to do. Over millions of years, the communication between our genes and the human body has undergone continuous improvements and upgrades, all to ensure perpetuation of the genes. Despite myriad improvements—much like Vista replacing Windows, or Panther replacing Tiger—the basic operating system of your genetic program remains the same.

Okay, you head-shakers, if all this just seems too fantastic to believe, let me ask you why you have no trouble accepting the fact that you can watch Oprah on your cellphone, thanks to invisible electrical impulses from outer space that communicate with cell towers to activate tiny computer programs in your handheld appliance. An invisible but...
