Want to know the exact number of calories your body burns each day? Like the contestants on The Biggest Loser, you can too! The bodybugg is used on the NBC hit reality series but there are other options with similar to identical results.

What is the body bug?

It looks like an arm band with an iPod Nano, but actually this device uses specialized sensors to monitor calories burned with over 90% accuracy. With the help of a Bodybugg, you know how many calories your body can consume and still lose weight. How much weight you lose is up to you! How? Here are some of the tech specifics from the Bodybugg's partner 24 Hour Fitness.

For $250, you can purchase a Bodybugg. In addition to the calorie tracking technology, you will also receive a diet program free for 6 months, a 45-minute phone coaching session to help get you started. They can be purchased through My Apex or 24 Hour Fitness.

There are also cheaper version that have now come out. Look on Amazon for a "bodybugg" look-a-like called GoWear fit Lifestyle and Calorie Management system with prices as low as $179. Another option is the Gruve Personal Calorie Burn and Activity Intensity Monitor, which will cost you about $230.

If you are trainer looking to implement a program like The Bodybugg, check out Body Evolver based in Boston. The Body Evolver program allows trainers to figure out the day a client should expect to reach their weight loss goals through body fat and lean body composition. Track a clients progress, monitor the number of calorie burned, and watch them succeed.

In August, I was lucky enough to experience Body Evolver and quickly found out that based on my body fat and lean muscle mass, I could eat 1500 calories a day without gaining a pound. However, if I exercised I would be able to eat about 100-300 more, depending on my intensity.

Since then I have been training with a personal trainer to reach my weight loss goals for an upcoming photoshoot! To see what exercises I have been doing with Mike D'Angelo of Revolution Fitness in Boston, check out our workout video.
