Low-Carb vs. Low-Fat: Which Is Best?
Behind the headlines of new study touting low-carb for weight loss and cardiovascular risk factors.
A recent headline-grabbing study seemed to settle the issue of low-carb versus low-fat diets definitively, reporting that a low-carb diet was not only more effective for weight loss, but also better for cardiovascular risk factors. In the yearlong study of 148 obese volunteers, those assigned to a low-carbohydrate regimen lost nearly eight pounds more and showed greater improvements in triglycerides, HDL cholesterol and a standard risk score for heart disease than a low-fat group. Both groups saw similar decreases in unhealthy LDL cholesterol. Researchers said the cardiovascular findings were notable because of concerns that low-carb diets might boost unhealthy cholesterol levels as dieters substitute fats for carbohydrates.
