Got my resting metabolic rate at work

[whitemerlot]

Do you get the results right away?

[wambam]

No, but I'm really curious about your results, if you care to share.

[sangria]

No but I'd love to do it.

I had it done at my nutritionist's office. Just as a tidbit from my experience: I didn't realize how caged I would feel having my nose pinched shut and only breathing through the mouthpiece.

It gave me a resting rate of 2000 calories. When she read the results after the 10 minutes, her response was "That's a little low for what I was thinking for you". I've severely jacked up my metabolism so she figured it was from me not eating enough for years.

When you put my info in the IIFYM calculator, it shows my BME (resting metabolism rate) as 1960 cal and my TDEE (total daily energy expenditure) as 2683 cal.

I had it done last week and I think it's wrong. 1400 were my results wambam a/k/a the one one who cares, lol

What does a BMR calculator give you?

[isabel]

So, this number tells you how many calories you should eat per day with no activity if you want to maintain your current weight?

Someone correct me if I'm wrong, but I think the resting metabolic rate is how much your body would burn if you were essentially in a coma, or just laid in bed without moving all day.

No.

BMR is the minimum number of calories your body needs to carry out basic functions like breathing. Any movement at all requires additional calories, which is what the TDEE measures.

ETA: I see this has been covered

Well, more like while sitting in a chair awake as the state you are in while performing the test. But more or less, yes it is meant to be a very baseline measurement.

You mean they don't induce a coma to accurately determine the resting metabolic rate? Nice shortcut, SCIENCE.

Does the number increase by a lot if you weigh more? Or is it similar because because it's just basic bodily systems?

I had it done a few years ago at my gym. It told me I needed 1620 calories just to simply exist. I'm 5'8 and (at that time) probably 160 lbs, fwiw.

Yes, body size usually factors into BMR.

Yes, body size usually factors into BMR.

Just as an example, look at my first post. I weigh 271. If I weighed 185 (my goal weight), my resting BME would be 1569 and my TDEE would be 2233.  So that's a 400 calorie difference in the BME and 450 in the TDEE.

Body box is the gold standard, but the test you did is probably within 10% of actual BMR.

This is so intriguing to me. So, do you have to fast? I would think what you eat impacts your metabolism, no? Or is this a case of using the word metabolism to refer to things that are actually different?

I didn't have to fast. It supposedly is able to read some element of your breath to be able to figure it out.
