You eat a lot of pasta, whole grains, spuds and rice. You've cut out most meat and fats rarely pass your lips. It may be the current diet wisdom, but according to a hot new bestseller, this diet may lead to less energy, more cravings and possibly, disease. The Zone is written by medical researcher Barry Sears, who believes that most people should eat more protein and fewer carbs for peak health. Of course, other experts are saying just the opposite.
Carbohydrates are the body's main source of energy.
They tend to be released in the bloodstream quickly, producing glucose for energy. Insulin is the hormone that transports the glucose to our cells. The Zone claims that too many carbs basically keeps the insulin working overtime. The perpetual up and down levels lead to fatigue, constant cravings and less endurance. If a food has a high or moderate glycemic index, you'll get a greater swing in your insulin level.
