aother dumb question about BMR

peasantgirly

I wore my HRM to bed last night and it says I burned 95 cals/hour while sleeping. (I read a book until I couldn't keep my eyes open, turned it on and went straight to sleep, and turned it off as soon as I woke up.)

Your BMR is what it takes to stay alive, like if you were in a coma, right? So, it's logical (to me anyway) to multiply 95 times 24 hours to get my BMR. That comes out to 2280, but MFP says my BMR is 1,668. Am I missing something? Why such a big difference?

Your HRM isn't designed for that.

plus you use more calories sleeping than you do when you are in a comma

A point that people miss when working out exercise cals. if u do x and it burns off 200 cals in an hour - that isnt an extra 200 its the difference between your BMR and 200

The reason I think eating your exercise calories on lower calorie burning exercise tends to fail but not the 1000/ hr MMA type one because there is less margin in the error

I have a bodymedia fit armband which is designed to wear while sleeping. I burn on average about 400 calories while sleeping. It does not measure your HR, but takes into account other things. Temperature, movement, etc.... It's a nice little thing to have to see how many calories you are burning everyday if that is what you are looking for.

You can`t really times 95 by 24 as during the day you may burn 500 an hour...So you`d never get an accurate figure doing it that way..

I have a KiFit (UK BodyMedia Fit) and it says I burn 1.2-1.3 calories per minute when I sleep, and usually 2 calories or a little bit more when sitting at my desk.

Ok, I'm not gonna argue this cuz it's probably correct. But I can't imagine there would be a noticeable difference. Not enough to explain a 600 cal difference between it and mfp.

I just used a third website to calculate it and it said 2700!

@jonski - I'm not trying to get the TDEE, just my base cals.

Have a look here...

It has calculators for everything weight related.

The problem is that I've used many bmr calculators and I get results anywhere from 1600 to 2700 and everything in-between. How am I supposed to know which one is correct? I realize they only give estimates, but what the heck am I supposed to do with an estimate that is 1000 cals off from another estimate?

That's why I was hoping I could get something a little more personalized by using *my* specific info (like my HRM), instead of relying on a generic one-size-fits-all formula. But that doesn't seem to be working either.

I guess as long as I continue to lose weight I should be happy. But I just feel like I walk a fine line some days between eating too much or (on exercise days) too little. I just wish I had a little better handle on it.

To be honest, i`ve used a few myself, but never had a difference in numbers as you have, most mine have been out is 100/200 cals either way...Never 1100...
