Evidence suggests that a low-carbohydrate diet can help people lose weight faster and maintain their weight better than a low-fat diet, according to the Harvard School of Public Health. A moderately low-carbohydrate diet with protein and fat selections from healthy sources is good for the heart.
Studies show that healthy diets with varied proportions of various macronutrients, including carbohydrates, protein and fats, worked equally well over a long period, states the Harvard School of Public Health. The low-carb diet was found most effective in reducing triglycerides, the primary fat-carrying particle in the bloodstream. It also delivered the largest boost in protective HDL cholesterol. A lower-carbohydrate diet consists of fruits, vegetables and whole grains containing essential vitamins, minerals and phytonutrients.
The Harvard School of Public Health reports that a 20-year prospective study involving 82,802 women found that women who maintained low-carbohydrate diets that were rich in fat or protein vegetable sources had a 30 percent lower risk of heart disease and around 20 percent lower risk of type 2 diabetes than women who consumed high-carb, low-fat diets. More studies reveal that a healthy low-carb diet that replaced some carbohydrates with protein or fat effectively lowered blood pressure and "bad" LDL cholesterol compared to a healthy, higher-carb diet. Furthermore, participants in an "EcoAtkins" weight loss trial who followed a low-carb "EcoAtkins" diet experienced improvements in blood pressure and blood lipids.
