This handy little gadget also came with a wristband for wearing it when you sleep. It monitors how restful you are sleeping by how much movement you make. I was pretty much getting 99% sleep efficiency every night, so I don't track that anymore. Mine just takes a break on the nightstand. And in the morning, when I pick it up, it says things like Move it, Burn it, Howdy, Love Ya, and other cute motivating sentiments.
If you want to track your food, you can do so on the Fitbit website. I use MyFitnessPal for that, and guess what, it integrates with Fitbit. So, if I forget to record my activity in MyFitnessPal, Fitbit will do it for me. I just love this little motivator. It was really an eye opener. On days that I work and spend most of the day at the computer, I usually only get around 2,500 steps. It makes me want to get out in the evening and at least take a walk around the neighborhood to get some exercise in. It has paid off because I've lost some weight and inches and I feel better. So, get a pedometer. I bet you'll be surprised at your steps. Well, gotta get moving. My Fitbit dashboard says I've only walked 32% of my 70,000 weekly steps.
