The simplest way to look at all these associations, between obesity, heart disease, type 2 diabetes, metabolic syndrome, cancer, and Alzheimer's (not to mention the other the conditions that also associate with obesity and diabetes, such as gout, asthma, and fatty liver disease), is that what makes us fat - the quality and quantity of carbohydrates we consume - also makes us sick.

Just as animal research tells us that gluttony and sloth are side effects of a drive to accumulate body fat, it also says that eating in moderation and being physically active (literally, having the energy to exercise) are not evidence of moral rectitude. Rather, they're the metabolic benefits of a body that's programmed to remain lean.

In 1960, fewer than 13 percent of Americans were obese, and diabetes had been diagnosed in 1 percent. Today, the percentage of obese Americans has almost tripled; the percentage of Americans with diabetes has increased sevenfold.

The point to keep in mind is that you don't lose fat because you cut calories; you lose fat because you cut out the foods that make you fat-the carbohydrates.

The laboratory evidence that carbohydrate-rich diets can cause the body to reain water and so raise blood pressure, just as salt consumption is supposed to do, dates back well over a century

We don't get fat because we overeat; we overeat because we're getting fat.
