A low-carbohydrate diet is more effective for weight loss and reducing cardiovascular risk factors than a low-fat diet, according to an article being published in Annals of Internal Medicine.
More than one third of American adults have at least one form of cardiovascular disease and cardiovascular disease causes one third of all deaths. Low-carbohydrate diets are a popular strategy for weight loss, but their cardiovascular effects are unknown, especially among diverse populations.
To compare the effects of a low-carbohydrate versus a low-fat diet on body weight and cardiovascular risk factors, researchers randomly assigned 148 men and women without clinical cardiovascular disease and diabetes to follow a low-carbohydrate (less than 40g a day) or low-fat diet (less than 30 percent of daily calories from fat).
Results and Discussion:
All participants were classified as obese based on body mass index and just over half of the participants were black. Both the low-carbohydrate and the low-fat groups received dietary counseling at regular intervals but had no specific calorie or energy goals. At one year, both black and white participants on the low-carbohydrate diet had greater decreases in weight, fat mass, and other cardiovascular risk factors than those on the low-fat diet.
