MFP Calories burned accurate?

That sounds about right depending on your age and weight. If you put your weight and age in on the cardio machine, it might be more accurate but for vigorous cardio 100-150 calories in 10 minutes is pretty common.

You have to look at a lot of the calorie estimates for food and excercise as ballpark figures that may be a bit optimistic so when adding in your food, err on the side of overestimating your calorie intake (especially since most people subconsciously underestimate how much they ate) and then it will probably be close enough.

well coupla of things........it is true that MFP's calculations will not be accurate for many of us, they are based on averages, so you need to invest in a good heart rate monitor with a chest strap for more personalized reports.

Then you need to adjust out your resting calories to make it even more accurate.

And, you do need to eat back the calories or at least most of them or this program won't work as well.

that said ellipticals and rowing maching really do work up a huge heart rate for most so 200 could be close. But back out your resting calories and record it.

The game here is all about accuracy, Many folks try to underestimate their foods and calories burned and then sorta shoot themselves in the foot. Do it smartly!

Absolutely not- I have found by far the cals burned on MFP are way over estimate. For my elliptical and treadmill time I punch in the data for calorie burn on the machine and am basically 50% less then what mfp says.

However. some things that are on for. I started doing internet searches at other sites for cals burned for various activities. As an example mfp says for every hour I use a push mower on my lawn I should burn 650 cals. At four or five other sites I got answers from 550 - 800 cals per hour of push mowing. So I figured 650 was accurate enough.

Always triple check on other sites or better yet get a monitor for walking, etc. and input your own calculations.

I've found them to be accurate most of the time - just to be on the safe side I generally over-estimate my food intake & under-estimate my calories burned through exercise. (for example I will input that I did 90 minutes stationary cycling @ light - but in reality I worked out at a higher intensity).

Been working quite well for me so far I think.

It's so hard to say whether it's accurate or not. For me personally, most of the exercises underestimate.
When I do cardio for example, I put everything I have into it so that I can hardly stand up after, so my calorie burn is 2-3x what the MFP would estimate. A HRM is your only accurate way. You wont have the same burn as the person beside you.
