Exercise MORE to Fight Mid-Life Weight Gain

At least an hour a day of moderate to intense exercise, such as brisk walking, bicycling or swimming, is necessary for women to prevent weight gain as they age.  That’s the conclusion of a new study that was published today in the Journal of the American Medical Association. Researchers at Harvard’s Brigham and Women’s Hospital followed 34,000 middle-aged women for 13 years: they were not dieting and were at a normal weight (their body mass index did not exceed 25) when they began the study.   On average, these women gained about six pounds during the course of the study. But those who reported that they exercised 60 minutes daily were able to maintain their normal weight throughout the study.

This piece of news is being reported in major news outlets today as if a cure for cancer was discovered.  Menopausal weight gain is a problem, to be sure. But was a 13-year study necessary to conclude that we need to exercise more as our metabolisms slow down? I wonder if women would choose exercise over a spa treatment if they had an extra hour to spare every day.
