Are Carbs more addicting than Cocaine?

In 2007, researchers at the University of Bordeaux, France, reported that when rats were allowed to choose between a calorie-free sweetener and intravenous cocaine, 94 percent preferred the sugar substitute. The researchers concluded that "intense sweetness can surpass cocaine reward. . . . The supranormal stimulation of these receptors by sugar-rich diets, such as those now widely available in modern societies, would generate a supranormal reward signal in the brain, with the potential to override self-control mechanisms and thus to lead to addiction...read more

How You Get Hooked (Over Time)

1. When you take in carbs, like Gatorade or whole-wheat bread, you secrete the hormone insulin. Even thinking about carbs causes this to happen.

2. Refined carbs spike blood sugar, and this is a big problem. The first result is that your body immediately stops burning its existing fat stores.

3. Too much blood sugar is a dangerous situation, and in response, insulin, a hormone, rips it from your blood and tells the body to store the energy as fat (in men this first happens around the waist).

4. Normally your liver controls blood sugar, but because you eat so many carbs you have a constant supply of insulin circulating. This turns out to be bad—very bad. This causes you to become resistant to insulin.

5. Insulin resistance means your body pumps out more insulin to make up for the deficit. Now you're getting fat, but what's worse is that your body desires even more carbs as fodder for the excess insulin.

6. You get fatter and fatter and your body craves more carbs to feed your increasing girth. This destructive cycle is why Americans are so overweight (the process doesn't happen overnight).
