I finally bought a MedGem! When I was working with Rebecca (trainer) at Bally's, every month or so, she would hook me up to this gadget called a BodyGem. It was a little plastic device about the size of a juice-box with a plug and a disposable mouthpiece. You breathe through it for about 10-15 minutes and it tells you your Resting Metabolic Rate (RMR) to a high degree of accuracy. (It calculates RMR based on oxygen consumption.)

The MedGem is a step up from the BodyGem -- the only real difference is that it reads your VO2 Max in addition to your RMR.



The box cost $2250 new (or more) but I bought it on ebay for $200! It came with software and half a dozen breathing tubes. I'm so excited to try it out!

Now, I'll be able to see if the 3 low1 high method really keeps my metabolism from dropping!
