A new study discusses the advantages of a low-carb v low-fat diet and its impact on heart health.

Low-carb diets of one form or another have been on our radar for quite some time as a way to quickly shed pounds, but we haven’t known much about how these types of diets affect our heart health.

All participants met with registered dietitians and received nutrition education, with emphasis on the benefits of monounsaturated fats and recommendations to limit trans fats. Those assigned to the low-fat diet were instructed to have less than 30 percent of their total calories from fat (less than 7 percent from saturated fat), while those assigned to the low-carb diet were instructed to limit their carbohydrate intake to less than 40 grams per day. Neither group was given a specific calorie goal. On average across the 12 months, participants in the low-carb group consumed about 130 fewer calories per day than those in the low-fat group.
