ORLANDO, Fla. (Ivanhoe Newswire) -- Need to lose weight, but don't know the best way to start? If you're in your 50s, cardiovascular exercise may be your best option.
Diet and exercise are both effective ways to lose weight. But if you're over 50, you may want to hit the treadmill to help maintain muscle mass when you're dropping pounds. A new study reveals caloric restriction promotes weight loss, but it may result in loss of muscle and aerobic capacity.
"The systems responsible for moving the body, the musculature and the cardiovascular systems, are being used in exercise-induced weight loss, therefore the body preserves them," study author Edward Weiss, Ph.D., of Saint Louis University in St. Louis, told Ivanhoe. "In the case of caloric restriction or diet-induced weight loss, there are fewer demands put on these systems, so the body degrades the tissues responsible for delivering oxygen and producing muscular force."
