Health Benefits of a Low-Carbohydrate, High-Saturated-Fat Diet.

A hundred years ago, before Americans changed their diet and the calamitous events of the 20th century began, heart disease was far less common that it is now. Few Americans were overweight, and coronary heart disease was not yet recognized as an illness. Pneumonia, diarrhea and enteritis, and tuberculosis were the three most common causes of death, whereas coronary heart disease is now the most common cause of death in the United States. The medical subspecialty of cardiology was created in 1940. Since then the number of cardiologists in the U.S. has grown from 500 in 1950 to 30,000 now — a 60-fold increase.

Americans have replaced saturated fat in their diet with processed polyunsaturated vegetable oils and carbohydrates. The Average American drinks 600 cans (56 gallons) of soft drinks a year (up from 216 cans in 1971). One-third of our dietary sugar comes from sodas, which has become the number one source of calories. Each 12-ounce can contains 10 teaspoons of sugar in the form of high-fructose corn syrup.

One of the major health benefits of a low-carbohydrate diet is weight loss. It enables one to lose excess weight without having to consciously restrict calories (Ann Int Med 2004;140:769—777). A low-carb diet lowers blood glucose in diabetics (Diabetes 2004;53:2375—2382). It improves insulin sensitivity (N Engl J Med 2003;348:2074—81). Indeed, carbohydrate restriction (with fat replacing carbohydrates) is on the way to becoming the preferred method for treating type-2 diabetes and its precursor, metabolic syndrome (Scand Cardiovasc J 2008;42:256—263). Restricting carbohydrates can also lower blood pressure (JAMA 2004;292:24822—2490).
