in Fitness and Exercise
I did 45 minutes on the elliptical today and, per the machine, it said I burnt about 310 calories. However, when I logged my exercise in MFP, it told me I burnt about 445 calories. Which one is more accurate?

    No-one can possibly tell you which is more accurate but if the machine gives you a power output (typically watts) go with that.
    Actually I would go with the machine anyway as it at least takes your effort level into account.

    You would need a pretty good fitness level to keep up the rate MFP suggests - only you know how fit you are.

    Both of them are probably wrong, since they just use an approximate formula that is wrong for most people.
    I usually just go with smaller number, it's better to underestimate.

    Use the Lower one. In my case, mfp is actually way lower than my treadmill (it's an old machine and doesn't let me input my stats). I use mfp since it's almost half the amount

    I'd use the lower # and even then I wouldn't eat the full amount back.
