A study by Iris Shai of Ben-Gurion University of the Negev, published in the New England Journal of Medicine (7-17-08), shows that low-carb and Mediterranean-style diet both beat a low-fat diet for weight control. While all 3 regimens improved cholesterol, the low-carb diet was most effective. The low-carb approach seemed to trigger the most improvement in several cholesterol measures, including the ratio of total cholesterol to HDL, the “good” cholesterol.
This remarkable study lasted 2 years, and 85% of the 322 participants stuck with the diets in a controlled environment — an isolated nuclear research facility in Israel. “This is a very good group of researchers,” said Kelly Brownell, director of Yale University’s Rudd Center for Food Policy and Obesity.
[Ed. note] This study clearly shows the benefit of limiting high-glycemic carbohydrates like sugar and white bread. It should not be seen as a blanket endorsement of the classic low-carb diet. Although the low-carb diet has been proven effective for weight control, it does not provide a well-rounded nutritional diet needed for optimal health. The best all around diet of the three is the Mediterranean-style diet; it has a long history of long histories – longevity that is. Follow this diet and you’ll avoid the bad carbs for best long-term results.
