South Beach Diet Beats Others in Keeping Weight Off

Photo Courtesy - Getty Images(COPENHAGEN) -- Many diets can take the weight off -- but when it comes to keeping it off, not all regimens are created equal, according to new research. A diet consisting of high-protein foods and ones with a low glycemic index is best for maintaining weight loss, said a large European study published in the New England Journal of Medicine.

The South Beach diet is the commercial weight loss plan that most closely approximates the best diet in the study, according to study author Thomas Meinert Larsen from the University of Copenhagen. The Atkins diet is much higher in protein, severely limits carbs, and has a more liberal attitude towards the types of fats one may eat.

The study followed roughly 780 participants who had already lost weight on a calorie-restricting diet and were randomly assigned to one of five different weight management programs.

Participants who ate foods higher in protein and with a low glycemic index not only stuck to their maintenance diets better, but were also more likely to continue to lose weight over the course of the 26-week study. In contrast, those assigned to diets consisting of foods low in protein with a higher glycemic index were more likely to regain weight.

Study Finds Not as Many Lives Saved by Mammograms

Photo Courtesy - ABC News(OSLO, Norway) -- As the debate rages among experts about whether women are unnecessarily over-screened for breast cancer, a new study may provide more ammunition to suggest frequent mammograms may not increase the chance of survival as much as once thought.

Published Thursday in the New England Journal of Medicine, the study suggested that mammograms reduce the chance of death by only 10 percent.  Researchers analyzed medical records from more than 40,000 women ages 50 to 69 with breast cancer in Norway and found that mammogram detection of breast cancer was responsible for only one-third of the women who survived.  Researchers said they used data to follow up with each patient after about two years. However, many experts expressed that is not enough time to track whether or not the mammogram helped the patient.

"It takes about seven to ten years to see the full benefit of mammographic screening," said Dr. Therese Bevers, director of the cancer prevention clinic at the University of Texas M.D. Anderson Cancer Center.  Dr. Daniel Kopans, director of the breast imaging division at Massachusetts General Hospital, agreed, saying, "No one presents data on breast cancer with only 2.2 years of follow-up."

Annual mammograms are recommended for women starting at age 50, and are thought to reduce the likelihood of dying from breast cancer by 15 to 23 percent, according to the U.S. Preventative Services Task Force.´╗┐
