Hi Guys,

I was just wondering how accurate the MFP is with calories that you have burnt during excerise, I do 30mins on my treadmill at 6kph (3.73mph) at a brisk pace and MFP tells me I have burnt 199 calories, but my treadmill tells me that I have only burnt 80! Whats the go with that? because of this I have been going off my treadmill, am I cheating myself out of burning off calories?? please help...

    Does ur treadmill take your weight into account? I find my walking/running on here is fairly accurate - maybe a little conservative. I used to wear the Bodybugg to count my energy expenditure so it was pretty right on. Not sure about some of the other ones though.

    well, first off does the treadmill have an option where you can enter your weight and age?

    Hey Guys,

    No my treadmill doesnt have an option to enter my weight, its a realitively El cheapo one but it still has the screen with all the buttons.

    Any now that i think about it - 80 calories seem pretty low. That would be low even more me, given that speed and amount of time, and im 120ish lbs. If you are heavier, you will definitely burn much more.

    Personally, MFP calories are always lower than what my HRM says I actually burned. My HRM takes into account age, gender, height, etc... I would recommend a HRM to get an accurate account of how many calories you're burning. The added benefit is that you'll know where your heart rate is as well. Good luck!

    To me MFP is always waaaay over on the estimated calories.

    If you are serious about knowing your calories burned, get a HRM.

    I also suggest getting a HRM if you really want an accurate count of calories. Definitely worth the investment!

    Also, when I'm trying to determine how many calories to eat back, I also take into account how many calories I would have burned just sitting there. For example, my BMR (basal metabolic rate) tells me I burn about 90 cal/hr just being alive. So when I do an hour workout, and my HRM tells me I burned 400 cal, I still only log 310 cal in to mfp, because I would have burned those 90 cal regardless.

    Thanks guys,

    I think I'll go out and buy myself a HRM... Its just seems too good to be true buring all those calories in such a short time. I know weight loss can be easy for some but I was thinking to myself "Surely I haven't burnt that much in such a short workout"

    I can only speak for the elliptical calories, but the MFP elliptical numbers seem to be almost double the actual calories burned. I don't use MFP for elliptical numbers.

    I wouldn't trust either. MFP is a decent guideline but it's not perfect. Fitness machines seem to be completely terrible in my experience. I did 30 mins interval training on an elliptical last night and I got:

    MFP: 527
    HRM: 513
    Elliptical: 64 (wtf?)

    I went with the lower and logged in 513. My HRM is an FT60 and it has all my stats including my VO2max so theoretically it should be the most accurate. But MFP wasn't off by much. Same thing when I do my walks, it's within 10-20.

    General rule of thumb for walking/running is 100 calories per mile. So the MFP number is fairly close.
