Everyone’s heard it: to lose weight and keep it off, exercise for 30 minutes, five days a week. But experts are having second thoughts about that recommendation-and no, they won’t suggest shortening your workout any time soon.
University of Pittsburgh researchers followed the fitness patterns of 200 overweight and obese women for two years. With each eating between 1200 and 1500 calories per day, they were divided into groups based on amount and intensity of physical activity.
Women in all groups lost 8% to 10% of their body weight after six month, but 75% gained half the weight back. The 25% that kept it off were in the group that exercised for an average of 275 minutes per week-125 minutes more than the current consensus.
“This clarifies the amount of physical activity that should be targeted for achieving and sustaining this magnitude of weight loss,” the researchers wrote in the Archives of Internal Medicine, “but also demonstrates the difficulty of sustaining this level of physical activity.”
