Researchers at the University of Tennessee studied a group of about two dozen men and women of various ages and activity levels. They compared the numbers of calories burned while each walked in place or sat during commercial breaks. Walking in place burned an average of 148 calories, twice the number burned from sitting. The calories burned while walking only during the commercials were half as many as the amount burned when the participants walked on a treadmill through the entire program.
We certainly have no shortage of commercial time during which to exercise. Today's average television hour has less than 45 minutes of actual programming, with the rest being filled with paid advertisements or station promotions, according to www.TooManyCommercials.com.
