In short, if you want to keep middle-age spread at bay and keep eating a normal diet, you're going to have to exercise a lot harder. By studying 34,000 women over a 13-year period, researchers concluded that moderate exercise for at least an hour a day was needed to keep the pounds off as this group got older.
