Has anyone here ever had a respiratory resting metabolic rate test done?
Link below happens to have a short vid showing someone getting the test performed...

One of the personal trainers at one of my gyms told me about it. I don't watch tv, but I guess they use this test on "The Biggest Loser" show also.
I would guess as you become fitter/thinner, then your past tests results becomes invalid? In the side article with this web link, it does mention this. Something about re-testing every 5lbs diff or 5% difference. Hmm, testing would add up pretty quickly. Don't know how much the validity is impacted.
Info / experiences, please share, thanks.
