Add this to the list of cool gadgets we'd like to try. The bodybugg armband is a wearable monitor that offers a running total of the number of calories you're burning (your Total Energy Expenditure, or TEE).

What's the big deal? Because the bodybugg not only tracks calories burned through regular exercise, but it also tracks TEE from the more mundane tasks of life, like changing a diaper, pumping gas, or even taking a nap. It does this by measuring skin temperature, physical motion, galvanic skin response, and rate of heat loss. And the manufacturer, Bodymedia, offers an impressive array of scientific studies proving the efficacy of the product in accurately tracking calorie burn.

The device interfaces with a proprietary bodybugg website, where you can upload your device data and input your food intake for the day. The site then computes your calorie deficit - the key to weight loss.

The bodybugg doesn't come cheap. It retails at $399, which includes a 3-month subscription to the website. While pricier than a pedometer, from a weight loss utility perspective the bodybugg may be worth the added expense.

You'd be surprised how many other diabeties gadgets can be used to help in bodybuilding.
