Has anyone used their HRM to determine TDEE?

Just wondering if anyone has worn their HRM all day to determine TDEE??

Even better...how did it compare to FitBit or BodyFit Media??

    TDEE?

    Seeing as HRMs are not designed for that sort of thing, it is likely to be inaccurate. BMF is the only monitor that actually measures 24/7. FitBit doesn't calculate rest periods, and an HRM would likely warn you that you are not in your exercise zones.

    TDEE?

    Total Daily Energy Expenditure....in other words....total calories burned in one day :)

    I am using a FitBit, and compared to the TDEE calculator I plugged information into, it is pretty close to that, within a couple hundred calories or so. FitBit may not calculate rest periods, but it shows periods of inactivity. For me, it was the most affordable solution to seeing some more information.

    I returned my FitBit...wasn't so impressed with it. I've been using my HRM and deducting what I would be burning at rest (my BMR calories) for workouts but I just curious to see about my TDEE.

    I'm going to give it a try.

    Might be interested in this topic: http://www.myfitnesspal.com/topics/show/569348-tdee-with-hrm-could-it-be-true

    The OP wore her HRM for an hour doing normal activities, then multiplied the result by 24. Apparently, the answer came pretty close to her TDEE number.

    LOL- Thanks...I just responded to her about an hour ago to ask what her original TDEE was based on!

    Cheers!

    HI... I just used a TDEE calculator on a website. :flowerforyou:
    When I did my experiment It was only about 20 calories different from my Sedentary TDEE (1733)

    *of course the HRM did show i was not in the "target zone", but it still calculated calories burned

    I wouldn't.. It won't be accurate.

    HRM's calorie calculating formulas are designed to be used during exercise only(more specifically, steady state cardio). Anything else, and they will be inaccurate.

    The calculator from this site: http://www.fat2fitradio.com/tools/bmr/ and my TDEE from my body bugg are pretty close if you are honest about your activity level.

    It will be way off, as the calculation in the HRM assumes a certain oxygen uptake that will not happen when you are not exercising so your results will not even be close to accurate due to this.

    A heart rate monitor really only works to calculate calorie burn while you're exercising. Heart rate is not an accurate measurement for metabolism/calorie burn when you're at rest and doing day-to-day activities.

    The estimate calculators work pretty well, but if you want a device to more accurately estimate your TDEE, try a BodyMedia Fit or a FitBit.

    That was my thought as well. HRM are designed to measure calories used during aerobic exercise. Any results gathered while not doing aerobics will not be correct.

    I wore mine all day even though everyone says it's not meant for that. I was just curious to see where my heart rate was all day and I tell you, I have a lazy job, my heart rate rarely went as high as 80 and in general I burned about 100 calories per hour. It was interesting to see.
