Respiratory Resting Metabolic Rate Test

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.:)

I had it done about 4 years ago. The information was helpful to me (knowing what my BMR was to figure out exactly how many calories I needed to be taking in to lose/maintain weight), but i had it done by a friend of a friend and it wasn't very expensive at all (I think I paid $35).

How much do they charge?

I had it done recently as well. I had that and body fat done and the folks that did it were glad I did as if they just went by my fat/lean percentages I would have had to cut my calories a lot more. The metabolic rate showed that I have a higher rate than just the 'fat pod' would have indicated. Perhaps due to being a bit more fit than my large size portrays.

I want to redo the body fat pod thingy :) in a few months, but hadn't thought much about redoing the metabolic rate analysis.

$40 ...with a discount I receive as a gym employee

thanks for the feedback... I want to know for the reasons that you did it as well... I've went on line and did the estimation formulas... but as my trainer co-worker friend suggested, it would be more accurate, and what I seemed to be looking for as an answer

Agreed... I really wonder the same thing about myself.

I know I consume a lot of calories. Thus, it's not a mystery to me from a food consumption standpoint why I don't loose weight with my current exercise levels. However, at the same time it also blows my mind that I can maintain my weight as it would seem I still take in way more that my body puts out. I think the test would be worth it.

that's not a bad price. Might be worth it to know the numbers- if you're a numbers person. I used to be. Now not so much. ;)

Ha ha ha... yes, I know what you mean. I am a numbers person. But some things I have reverted the other way totally. Part of me does want to know my number... um, then this other part does not.... :rolleyes:

because I would actually have to count calories then *gasp & sigh*

I actually had it done at my gym quite a number of years ago. Frankly, the results were rather shocking. At the time, I was on a very strict, low cal, high exercise diet. I had a 19% body fat (same as right now, actually). My RMR was less than 1000 calories (I believe it was like 989 if I remember correctly). I was stunned.

Now I'm at the same body fat, 10 lbs heavier and I easily consume well over 2500 calories per day. I would bet that my RMR is closer to 1700 now. My GoWearFit (like a body bugg) tells me that on non-exercise days, I burn about 1700 - 1800 calories.

That test showed me how badly I had damaged my metabolism with strict dieting and excessive exercise! :eek:

Funny, most charts tell me that at my size, I'd have to starve myself continuously to maintain the weight I am at. I know I eat at least 2,000 calories a day and probably around 2,500 on days I ride or run. If it's a really hard ride, like the climbing i did last weekend, it might be 3,000 :eek:. My weight stays within 4 lbs if I exercise the way I usually do; my body fat is always around 18%. I definitely could not eat < 1,000 calories a day!
Maybe it has to do with the type of food I eat? I don't work out the way some of you guys do, but I think it would probably be rated as more than "active" than some of these calculations use.

That is a really interesting thought... and one I had forgotten about...

When I lost my most major weight, I ditched the three meals a day plan. Lots of smaller meals throughout the day is how I continue to eat. Actually, I think I eat constantly sometimes lol.:o:rolleyes: BUT, it does probably help my metabolism keep going... as my body does not sense famine. Hmm.

I know, me too...

I've even added in the calories for activity level guesses on charts, and thought... omg, really? are you kidding me?? I just ate that much in the day and we've got a while to go until it's over.:eek:
