are MFP workout calorie counts acccurate?

alisonrose01

I've still new to MFP and I've noticed the calorie counts for workouts being crazily high. I'm not overestimating what I am doing (at least not by much) but the counts seem way off for what I've come used to....seeing how many calories on average burned based on cardio equipment at gyms and a heart rate monitor I used to wear.

Has anyone else experienced this?

For example, 40 minutes of circuit training is 486 calories burned according to MFP. But that's not even an hour of a workout!! Can that really be accurate?? It seems 300 is most likely the max a person could lose in an hour!

Thoughts?

they are a bit off....really more of a guide. Best suggestion would be to get a heart rate monitor. Gives you the exact amount you burned. Good luck

I also recommend a heart rate monitor. I use one and usually burn about 350 calories for 45 minutes of circuit training, but it is a class and the teacher kicks my butt.

I don't have a HRM yet, I'm hoping for Christmas I'll get one. I've been going by the machine (elliptical) since I put in my age and weight. For 33 minutes on the elliptical I burn about 300ish calories. MFP says I burned like 450ish. I just manually input the calories that the machine tells me I burned. Weight lifting seems about right to me, at least for me. By the time I'm done with the weight lifting boot camp I am a breathless sweaty beast so I am hoping I'm not too far off what MFP says. Then I usually try to leave some calories not eaten to make up any difference in error on MFP's part or mine.

It seems the more precise an exercise is, the more accurate it is.

Something like "Walking 3.0 mph" or "Running 6.0 mph?" Pretty close.

"Elliptical?" There's no way of knowing what kind of speed or resistance you're using, so it's as accurate as a stopped clock.

When I do circuit training at my gym I usually burn around 550-600 cal in an hour, and I'm 126 lb...

I think it might depend on what you're doing and what intensity.

I am highly skeptical of some of the counts on MFP though -- for instance, fishing from bank, archery, and bowling.

I've actually found that my HRM tells me I burn more on the treadmill than the treadmill tells me, and MFP in general is fairly reasonable in its estimates.

I use my HRM, and I burn SO MUCH more then they say.. I tweaked it and played with it and even reset my HRM to make sure it was reading accurately and it is...

HRM is the best way to go I think... everyone is going to burn differently depending on weight, endurance etc.

I NEVER go according to what the equipment at the gym says...I use to take my heart rate the old way (counting how many beats of my pulse in 6 seconds and multiplying that by 10) to give me an approximate number, and multiplying that by the amount of time I exercised... to see what was what.

Wow overwhelming suggestions to get a HRM! Thanks for the input everyone. I now know not to trust the counts but will most likely input my own number. It's mostly about the boot camp/circuit traning type activities that I think are off.

Thanks for all of your responses!

I found MFP to be accurate.

As a ballpark I burn about 100 cals per 10 min of running/cross training once I get my heart rate up...

3 miles for me at 9 min/mile is about 300 calories...5 miles about 500 give or take. Cross training is 200 cals for 20 minutes of work.

Of course a heart rate monitor will give you more of an exact figure but you can burn 500 cals in an hour, if you're working hard.

When I first started and my unfit body worked harder, the calorie estimates were a *little* high, but closer. Now, they are WAY too high. I think the default settings assume a pretty minimal level of fitness. Your body adjusts and it becomes harder and harder to raise the heart rate. I do interval training now and still can't reach the estimated calories burned from the site.

Ditto from other posters, get a HRM as soon as possible because it provides a more appropriate estimate.

40 minutes of circuit training is 486 calories burned according to MFP.

That's not out of the norm. 1,000 calories would be a bit much, but it's quite possible you burned 486 in 40 minutes.

Btw, I don't have a HRM but I have an iPhone with an app that are often over MFP's numbers.

I just got a HRM and the numbers are SHOCKINGLY accurate for me. I thought that MFP would be way high. But it seems to be almost dead on for me within a 10% margin.

You can definitely burn 10 calories a minute or more, especially if you're bigger/heavier. That said, MFP probably overestimates a lot.

Another approach when logging stuff is to be less concerned about the calories reported, and rather know that you are working out very hard (by RPE or HR, whether manual or through a monitor). 'Cause all you can do, in the end, is work as hard as you can in the time you have, and eat a sensible calorie deficit, and whether the computer is spitting out accurate numbers or not is not going to affect your results...

MFP good for me.

I just ran the Turkey Trot 8k (about 5 miles) in 39 minutes...that was 550-600 calories...because the pace was fast -- at least fast to me! (<8 minutes/mile).

MFP overestimates a lot for me for most things compared to my HRM.

OP, Google "how many calories can I burn for <your activity>?" and see what you come up with. I found this:

"On average, a 150-lb. person can expect to burn 536 calories during an hour of Zumba. By comparison, the same person would burn 413 calories during an hour of moderate swimming, 477 for an hour of casual racquetball and 684 for an hour of running at a 10-minute-mile pace."

I've found it to be pretty accurate for me compared to my HRM.

ditto with the HRM.
