No license to cheeseburger. This week, a major study on the impact of reduced fat diets on cancer and cardiovascular disease in women over 50, showed “no significant changes in risk despite years on reduced-fat regimens,” according to the San Francisco Chronicle. Click here to see a NewsHour interview with Barbara Howard, a lead investigator in the study and Dr. Peter Libby, chief of cardiovascular medicine at Brigham and Women’s Hospital in Boston.

Remember, it’s the calories, baby. Dr. Libby elaborates:

“I think it’s very important that the listeners not take this as a license to chow down on cheeseburgers because the overall caloric content is probably as important if not more important than the specific food components, so unless your calorie intake equals your calorie expenditure, you’re setting yourself up for gaining weight. And we know that that has horrendous consequences for cardiovascular health.”
