Women who want to lose weight and keep it off need to exercise for almost an hour, five days a week, according to a new study from the University of Pittsburgh.
Researchers found that a 55-minute regime was the minimum needed to maintain a 10 percent drop in weight.
During the four-year study, 200 overweight and obese women were told to eat between 1,200 and 1,500 calories a day, and do one of four different exercise programs, which varied in intensity and variety.
After six months, all of the women lost up to 10 percent of their body weight, but only a small percentage was able to maintain it. Those who did keep the weight off were those doing more exercise — about 275 minutes a week, on average.
Research points to a combination of exercise and calorie control as having the best chance of success in weight loss. This latest research once again confirms that plenty of exercise is a key ingredient.
