The body's primary fuel source is carbs (sugar). Glucose is the elemental form of sugar that the body relies on to function (i.e., it enables the brain to think). The problem is that the foods manufactured for at least the last four decades contain more preservatives (read: sugar and fat) in order to increase shelf life. The downside is the body can develop an addiction (much like one may have with a drug) to these foods in order to feel good. David Kessler, who wrote "The End of Overeating: Taking Control of the Insatiable American Appetite", has described how the fast-food industry has combined sugar, fat and salt into highly-engineered foods which target the pleasure centers of the brain. Case in point can be found in the movie "Super Size Me" which chronicles Morgan Spurlock's experience over a month of eating nothing but fast-food and suffering near-fatal health consequences. A bit extreme but nevertheless makes a point.
The scenario is this: eat a sugar-laden food; blood sugar and insulin levels rise dramatically and you feel good; eventually blood sugar and insulin levels drop and you feel bad; eat more sugar-laden food; blood sugar and insulin levels rise even more dramatically and you feel great; eventually blood sugar and insulin levels drop and you feel really lousy; eat even more sugar-laden food; and so on and so on and so on...congratulations, you're now on a roller-coaster ride that has no stop!
Laboratory researchers have found that high-fat, sugary foods have addictive-like qualities, stimulating the pleasure centers of the brain, and making one crave for more and more of these foods in order to feel good. The dopamine receptors within the brain become more diminished as the addiction wears on. This causes one to develop more of a craving for foods which trigger dopamine (feel-good chemical) release.
The solution is not to personally ban tempting sugar-laden foods as this will only encourage more of a craving. Instead, drink water or tea prior to eating these foods as the liquid itself will lessen one's satiety and therefore diminish one's craving. The result: eat less of the food and not experience a dramatic blood sugar rise and fall.
