How accurate is the calorie burn?

I was just wondering if anyone had a fancy heart rate moniter while they worked out to see how many calories you really burned vs what mfp says .. after my two workouts today, it said I burned 1617 calories.. Just wondering if these numbers were close to accurate.. Thanks!

    Most folks here find the MFP numbers to be ridiculously high. Before I got my HRM, I took whatever number MFP gave me, then cut it by at least 25%.

    Mfp over estimates everything except running it seriously under estimates how much I burn. Hrm are not accurate in weight lifting calories just an FYI =]

    Everyone says that MFP numbers are biased high, but I do not find the MFP numbers to be that high. Do they vary a lot with weight? I am only 117 lbs so maybe there is more emphasis placed on weight in the MFP calculations?

    Once I got my HRM I found that it was off by 150-200 cals or so. Not sure if this helps a whole lot... if you are thinking of investing in a HRM, DO IT!!!

    I thought LONG and hard about it before I did, but I LOVE mine. Got it on Amazon for $60... totally worth it!

    MFP is so generous with cals burned. I was really disappointed when I got my polar FT4 and it was so low compared to MFP. There was at least a 125-200 cal difference.., I recommend getting a HRM with a chest strap !!

    For me the MFP calories are insanely overestimated, it depends how fit you are and a bunch of other variables but I would strongly recommend a good HRM with a chest strap!

    I have found some to be very high - especially "circuit training general" under cardio. I find a good estimate to be a brisk run burns about 10 calories a minute and gauge my exercise off that. If MFP estimates calories higher than that for what I'm doing then I decrease it accordingly. best of luck.

    Which one did you get for $60?? All the Polar ones I was looking at were like $110.

    From my experience MFP is both high and low on their calorie calculations, which should be expected as it's impossible to make it accurate for everyone. I definitely recommend getting a heart rate monitor. I can only speak to a few of the cardio categories. I have found that the MFP elliptical and stairmaster calculations a bit high depending on how hard I work. I have found that the MFP strength training calculation is insanely low (MFP is around 250 cal / hour and I'm burning closer to 600 cal / hour). Hope that input helps.

    HRMs and MFP have never been accurate for me. Plus, they don't tell you what your EPOC is.

    I think it does vary with weight, example I weigh 278 so I have to work harder moving my extra weight in that hour of cardio than say your 117 frame..Its like me adding a 161 pound weight , so it makes since I would burn more calories..I just don't know if 50 minutes of turbo jam like classes are burning 1050 calories a class for me..

    I totally agree with everyone here. The estimates on MFP are way higher than on my FT4. I too was dissapointed to see that I was burning much fewer calories but at least I have an accurate burn now. I love my FT4!

    I don't have a HRM, anxiously awaiting buying one....but my friend does have one and she says her HRM is usually about 30-50 cals less than MFP on an hour walk at 4.0...so take what you will...Hers doesn't have a chest strap the one I am getting will, so I'll update you on that comparison later...lol....I always an in the green for calories so if it is high like everyone says I compensate that way?...Everyone is different so I assume for some it's WAY off and for others it's closer....

    MFP gives me 324 calories for 50 minutes of circuit training which is less than 7 calories/minute. Like I posted earlier, I think MFP puts too much emphasis on weight.

    FT4 is 67.00 from the Polar website and it comes with the strap of course. Very much worth the investment!
