It’s good to see more mainstream research coming out to reinforce what many of us already know…
Boston, Mass. – A new study published today in the Journal of American Medical Association challenges the notion that “a calorie is a calorie.” The study, led by Cara Ebbeling, PhD, associate director and David Ludwig, MD, director of the New Balance Foundation Obesity Prevention Center Boston Children’s Hospital, finds diets that reduce the surge in blood sugar after a meal–either low-glycemic index or very-low carbohydrate–may be preferable to a low-fat diet for those trying to achieve lasting weight loss. Furthermore, the study finds that the low-glycemic index diet had similar metabolic benefits to the very low-carb diet without negative effects of stress and inflammation as seen by participants consuming the very low-carb diet.
And, surprise, surprise, they’re finding just what I’d have expected.
The study suggests that a low-glycemic load diet is more effective than conventional approaches at burning calories (and keeping energy expenditure) at a higher rate after weight loss. “We’ve found that, contrary to nutritional dogma, all calories are not created equal,” says Ludwig, also director of the Optimal Weight for Life Clinic at Boston Children’s Hospital. “Total calories burned plummeted by 300 calories on the low fat diet compared to the low carbohydrate diet, which would equal the number of calories typically burned in an hour of moderate-intensity physical activity,” he says.
