Weight Gain When Exercising Aerobically Can Be Prevented

A U.S. study of 81 overweight, sedentary women who participated in an exercise program ostensibly to improve their fitness found that many of the women actually gained weight over 12 weeks. The researchers wondered why. Almost 70 percent had added some fat mass, and several had gained as much as 10 pounds, mostly fat. But those who had lost weight after four weeks tended to continue to lose weight. The researchers concluded that the best way to lose weight when exercising is to check the scale after a month: if you’ve lost weight, then stick to the diet and physical activity level that has worked so far.
