Low-glycemic load diet may improve ability to stay on diet longer
Low-glycemic load diets, those low in sugars with moderate levels of carbohydrates and not as low in fat and protein, may lower metabolism less when compared with low-fat diets, making the dieters feel less tired, cold and hungry, as well as improve cardiovascular risk factors, according to an article in the Nov.
