Is A Brisk Walk Better For Weight Loss Than The Gym?

PHILADELPHIA (CBS) -- Taking a brisk walk may be better than working out at the gym to keep weight off, according to a study.

Researchers in London found that people who walk regularly for more than 30 minutes have lower body mass index numbers--and smaller waists-- than those who go to engage in regular exercise.

The effects were particularly noticeable for women, and both men and women over 50.

Researchers conclude "promote walking as a potentially effective way to tackle obesity rather than public health messages on healthy diets."
