"Hi, I'm Dr. Mark Hyman, and I'm here to tell you how to use revolutionary new science, the science of nutrigenomics, to reprogram your genes to automatically lose weight and regain your health. ... You literally can reprogram your genes by changing the way you eat ... During this program, I'm going to teach you about the myths that make you gain weight ... 'Now, what is he talking about?,' you might be saying. 'I thought genes were something you got from your parents. ...' But no, genes are every moment, every second, interacting with your body, interacting with your environment, with the food you eat, with the stress you're under, with the thoughts you have. Everything is turning messages on or off in your DNA that literally controls your metabolism." Well, first of all, it's not a "myth": your genes are something you got from your parents. Saying that your genes are "interacting" with your environment, however, is a myth. "Interacting" means that your genes act upon the environment, and the environment acts upon your genes, but neither of those is actually happening. Indeed, you absolutely and categorically cannot "reprogram" your genes by eating differently. The genes you were born with are the genes you will die with, except for any that might get garbled by mutation or viruses or cancer. What Dr. Hyman actually means is that you can affect the genetically programmed responses of your body by changing your circumstances and your environment. If you are hot, your genes have programmed your body to perspire, but moving from the arctic to the tropics is not "reprogramming" those genes. It is simply giving different input to your body, which has genetically determined responses.
"If we understand this new concept, that we can use food, that we can change our environment, that we can change the way we live in our lifestyles, to literally communicate messages to our DNA, to turn on health and weight loss, then we have the problem of obesity solved." Well, no, actually you can't "literally communicate messages to your DNA." It's a nonsensical assertion. To be specific, your DNA has no receptors with which to receive "messages" from your food or your body or your environment.
I promised you the true secrets of weight loss, though, so here they are:
- Eat when you're hungry, but don't eat when you're not hungry.
- Stop eating when you're satisfied, not when you're absolutely stuffed.
- Eat healthy, nutritious food, in reasonable portions, with modest amounts of "treats" like candy and desserts.
- addendum: Eat slowly and chew your food thoroughly. If you rush through eating a meal, your stomach doesn't have time to send a signal to your brain that it's full, making it easy to eat too much before you realize it. Eating slowly also gives you the opportunity to savor your food — your taste buds get the same joy with less food. Finally, eating slowly and chewing thoroughly improves your digestion.
- Exercise regularly.
The secret is that it's all vastly "easier said than done." You won't have sustainable weight loss by going on a crash diet. You have to make real and lasting changes in your eating and exercise habits, and there is no way around that reality.
