<p>Some high-tech gizmos can be helpful for those who want to slim down. According to researchers at the University of Tennessee, the average adult takes 5,117 steps per day -- about half the recommendation by the U.S. Surgeon General. The Fitbit, which is a sort of juiced-up pedometer, encourages you to walk more by tracking how many steps or stairs you take, as well as the distance you travel and calories burned, and you can check your progress online. Fitbit offers a Wi-Fi scale for $130, or you can use the Wi-Fi body scale by Withings (in Apple Stores) which will transmit your weight to your iPhone, iPod or iPad. How's that for motivation?
