Walnuts: A Weight-Loss Weapon

by Berkeley Wellness  

If you love walnuts—and are trying to lose weight—here's some good news: New research suggests those nuts can be a heart-healthy addition to a weight-loss diet.

In a study in the Journal of the American Heart Association, 245 overweight or obese women (ages 22 to 72) were enrolled in a structured weight-loss program and assigned to one of three diets: lower-fat/higher-carb; higher-fat/lower-carb; or walnut-rich higher-fat/lower-carb. The walnut group ate 1½ ounces of walnuts a day. After six months, all groups lost equal amounts of weight (about 15 pounds). The walnut group had the most favorable changes in blood cholesterol, including a small rise in HDL (“good”) cholesterol. Walnuts are the only nut supplying a significant amount of alpha-linolenic acid, a potentially heart-healthy omega-3 fat.

The study was conducted by researchers from the University of California, San Diego, and was funded by the California Walnut Association along with the National Institutes of Health.
