Exercise Smarter Not Harder

You've probably heard by now that the Centers for Disease Control and Prevention recommends that people exercise a minimum of 30 minutes a day, five days a week. But a new study takes that a step further with advice that working out smarter, not harder, may be the key to losing weight.

"Everyone believes that the harder I work, the more benefit I get. In this study, we really didn't show that. The harder you worked, it didn't really result in greater weight loss," said John Jakicic, Ph.D. at the University of Pittsburgh.

Dr. Jakicic led part of this study, enrolling about 200 overweight women, ages 21 through 45, in a year-long diet, with a support group but in four different exercise programs. Researchers found the women who did high-intensity exercise lost essentially the same amount of weight as those who exercised moderately.

So what's moderate mean? The study describes it as a brisk walk, as if you're hurrying to a meeting. Women who did that for at least 50 minutes, five times a week, ended up with the best long-term weight loss.
