I don't know how many of you watch The Biggest Loser, but I love that show. If you ever notice, most of the time they have a black armband around their upper left arm. It is called a BodyBugg and I bought one 5 weeks ago and I LOVE it!! It is the best invention EVER!!! It actually keeps track of how many calories you burn during the day. Then you go to their website and log in everything you ate so that you can always have the calorie deficit necessary to lose weight. We set it up with my goal to lose 2 lbs a week which means that I need to have around a thousand calorie deficit each day. And it has worked like clock work!! So for those of you that need to lose a ton of weight like I do...this is a REALLY good contraption! Go to http://www.bodybugg.com/ to see how it works.
