BMR Question...

Is it possible to wear my heartrate monitor for 24 hours straight to get a more accurate idea of my BMR? I thought I saw one of my friends on here talk about doing that before and there was a reason which I can't remember now of why it wouldn't be accurate...What are your thoughts?

    From what I've heard HRMs aren't reliable when worn for long periods of time, especially ones that require you to press your fingers against the sides. I'm not sure why that is, but it's what I've heard over and over when others have your same question. Some doctors and nutritionists can do some sort of test that figures out your specific BMR, but for the most part you should be just fine using the estimate MFP gives you.

    You can give it a try, but a good chance it will slip or not read right. I heard body bugs work better though. Something to think about.

    Yea I don't care enough to spend the money on a body bugg. I have a polar FT7 so I don't have to touch the sides or anything I might just try it and see how close it comes to the MFP estimate.

    No, not a regular one. I read somewhere that the equation they use to convert heart rate to calories is only valid during cardio exercise. It's not a linear relationship. The body bug and stuff use other variables (I know including skin temperature) to make their calculations.

    HRMs only accurately record caloric burn when the heart rate is elevated. If you don't want to invest in a BodyBugg you look ini finding a BodyMedia Fit on sale through Costco (comes out to less than half the price of a BB when you factor in the site subscription) or there's some other device that's sorta similar called, I think, a Fitbit, that you could look into.

    Mind you, none of them will give your exact BMR unless you actually just lay in bed all day for 24 hours without moving. But ou can sorta still estimate it based off your resting per minute caloric burn multiplied out for the full day.
