If you’re looking for an affordable and efficient way to stay on track with your energy output and caloric intake, purchase a Fitbit Ultra. This little guy discreetly attaches to you and accurately tracks your daily steps, stairs climbed, distance, calories burned, and activity level via 3D motion sensor and altimeter technology.  It also measures how long and how well you sleep – just wear it on your wrist at night with a Fitbit wristband (included).  Then you just wirelessly upload the data on your computer to Fitbit.com to track your results.  And there’s no monthly fee!  I just love mine in that it provides me with a reality check so that I know I’m not taking in more calories than I’m burning and when I want to drop a few extra pounds it helps me create a caloric deficit.
