jemhh - I pay out of pocket. It's less than $100 at our local women's hospital to have it done. It's a little gross (you breathe into a device for several minutes and when you take the thing out of your mouth spit goes EVERYWHERE) but well worth it to me.

peachyfuzzle and ninerbuff - My RMR is 400 calories more than where it was many months ago when I started running. I had it tested then and I just re-tested. My food calories from exercise are in addition to my RMR.

LOL For the record.. Actually she said both...

The test she's talking about wouldn't measure TDEE. While I find a 400 cal/day uptick in RMR to be fairly unbelievable also, there's no chance she's confusing the two.

"During the Resting Metabolic Rate test you will be asked to relax in a chair while your oxygen uptake, carbon dioxide output, and electrocardiogram (EKG) are measured for 16 to 20 minutes. To measure the amount of oxygen your body is using and carbon dioxide it is producing, you will be asked to wear a face mask that covers your mouth and nose (similar to an airplane pilot’s mask). The face mask will not provide you with extra air, you will only be breathing from the air in the environment. Ten EKG stickers and leads will be attached to your chest to monitor your heart rate and rhythm. It is very important that you remain as relaxed as possible to get the most accurate results. "

The EKG bit is not required for the test. Some groups use it for additional info, some don't.

I wonder how much results can vary because of this.

I often wonder if there is any training on what is a realistic result for the techs administering these tests, or the people sharing the results. They should know that a 400 calorie change per day is impossible. Others have posted here in the past that they were told their RMR was something ridiculously low, like under 700, I think. They shouldn't be charging $50-$100 for these tests if the techs can't spot nonsensical results and re-run the thing.

Yeah, for me "relaxed as possible" can be many different things. It can be near comatose, or a bunch of wiggling and twitching that I'm barely aware of. (I remember taking a polygraph for a job application back in the 80's and the tech was super pissed by the end because he kept having to tell me to sit still.) Trying to stay that calm for 16-20 minutes would typically be a form of torture for me, unless I happened to be in the right state of mind for it. But I imagine if I were to succeed the one time and not the other, it would make a big difference.
