reviewed nine studies on pedometers, walking, and weight loss.
In the studies, overweight or obese adults
started pedometer-based walking programs without dieting. Pedometers are
pager-sized devices, worn on the waist, that log steps taken.
The studies' details differed. In some studies, participants walked 10,000
steps per day. Participants in other studies got personalized goals, such as
walking an extra 1,000 steps daily. The longest study lasted for a year; the
shortest study lasted a month.

and colleagues write in the Annals of Family Medicine.
People might lose more weight if they also upgraded their diets, but that

Another study, published in November, shows that pedometers motivate
people to walk more, improving blood pressure as well as
