Calories burned

I've noticed my calories burned varies quite a bit from what MFP says and the machines at the gym. What does everyone else go off of?

    neither is particulary accurate.

    If you were doing cardio it may be helpful to invest in a HRM.

    What rainbowbow said.

    And for lifting just count it as a deficit calculating error cushion because it really isn't much.

    Heather - I noticed the difference too. I got a HRM and go strictly by that. I think I paid about $60 or $70 at Academy. Well worth the investment.

    Calorie burns are often overestimated, therefore most only eat back a portion (50-75%) of the burns.

    I do not count any burn from strength, weight training. I do not trust the machines. Before getting my Fitbit I counted my walking for exercise, I did it by miles and time, so if I walked for an hour and I went 3 miles, I would count it as moderate pace in MFP, and only eat back a portion of that back. If I was losing too rapidly, I would eat more back, too slowly, I would eat less back.

    Thanks for all the advice. I do 60 min of cardio usually on the treadmill at a pace of 3.5 or faster with an incline of at least 4. I only eat about half of what MFP says I earned.

    I've had similar questions. If I weigh 350lbs, walk 40 minutes at 3mph am I really burning the 345 calories MFP says? A HRM or Fitbit is a great idea and with Christmas coming maybe I'll treat myself.

    This is why I switched to the TDEE method. No need to futz about trying to calculate how many calories I burn doing any specific exercise. I just looked at actual weight loss over time and actual calories consumed, and reverse-calculate my TDEE and took a deficit from there.

    You can cross check the calorie burn on a lot of the calculator sites. Keep in mind that even the trusted calculators are at best estimates. Every body shape and stride is different, and heart rate comes into the picture as well.

    But I'd say that is fairly close.
