Actual exercise calories burned? Machine vs myfitnesspal?

So Question: When logging exercise, the machines at they gym tell me I burned a certain number of calories, and when I log the exercise into myfitnesspal.com the website tells me I burned way significantly more than the gym machine says I burned.

Does anyone know which is more accurate and which one I should log?

I don't want to think I'm burning more calories than I am, as I started with a 70 pound weightloss goal, and still have a good 50 lbs to go.

  • Usually the ones at the gym don't take into account your weight, but, on the other hand, they know just how hard you're working, so it's a hard one to call. Quite a number of these sites and machines are quite inaccurate. Probably neither are completely accurate.

    both are probably inaccurate. You may want to get a HRM to get a more accurate estimate

    You need a HRM to get the best reading, but between the machine and MFP, I'd go with the machine, MFP is very innacurate in my opinion........says you're burning way more than you really are.......

    go with the lower amount, everyone will differ in how many they burn even at the same height weight age and gender. there are variables that have to be taken into consideration which can contribute to the amount of energy we expend.

    I'd like to know the answer to this as well because I get different numbers too. I usually go with the calories burned on the machine but I put in my weight and age in the machine. I also adjust the levels of resistance throughout the workout so I figured the machine would be a bit more accurate than MFP. When I log my exercise I'll just decrease the minutes in MFP until it shows calories burned that's close to what the machine said. Hope this helps :)

    I started putting in the number on the machines, you are right they are way less on the machine! I bought a fit bit at fitbit.com and it really does a good job of telling me actually how many calories I burned for real. It still takes into consideration the amount of calories I said I burnt from machines and minuses them from my total so I get a better idea. Just keep moving! that is all that matters in the long run~!!

    Definitely get an HRM, I tested mine against the stairmaster and the treadmill and both were wrong.

    I would always go with the lower but neither are going to be accurate. I used to log the calories according to the machines but now I have a heart rate monitor watch with strap that also shows my calories burned and I use that since it takes in account my heart rate.

    I myself have noticed that MFP is alwaysa little higher then what the machines say. Truthfully though I don't think either are completely and 100% accurate. It is more of an average I would think...

    What I have been doing is logging in a few mins less of exercise time on MFP. I do this mainly because I am scared that it isn't accurate and that I will end up eating back too many calories...

    As long as I input my weight into machines, they're really close to MFP's estimates.

    It really comes down to trial and error. If whichever estimate you use gives you the results you want, then it's close enough to accurate.

    MFP, gym machines and HRM's all have varying degrees of inaccuracy! Nothing is going to tell you exactly what you burn, just like food labels aren't 100% either!

    If the machine asks me for my weight and age I tend to use that number (by changing the calories burned not by adjusting the minutes worked out), if not I tend to use the number on MFP becasue it is normally lower. I also don't usually eat back all of my excercise calories I usually leave about 20-25% for error in calories out but also calories in!! Haven't purcashed a HRm yet and not sure I am going to - I've come this far without one!

    As with most things this is about trial and error - what works for someone else may not work for you! Chose one log it and give it a couple of weeks if it works great if not change it up. This journey is as much about learning about your body to help you keep the weight off as it is getting it off!

    Good luck! :drinker:

    I use a very good treadmill each day and it records 250-300 calories for about 45-60 minutes.
    If I used the MFP's allowence for the time spent on the treadmill I'd be at my goal now. :)

    Be realistic. I log what my machine says.

    Besides as long as I'm getting a good hour in that's all that really matters.
    Every week I push myself a little further, up the speed, up the incline,and switch up the programs. I just keep moving this body.
    Good luck in your journey! And don't get so hung up on the numbers.
  • i invested in a heart rate monitor watch which includes a calorie counter. You wear a strap around your chest which relays the info to your watch. The amount of calories burnt depends on your heart rate. I have found this is the most accurate way of finding out how many calories you have burnt.

    I’m in the neither camp. An HRM is the most accurate and you don’t have to get the expensive ones that calculate calories burned. All you need is your average heart rate and you can use a formula to determine.

    Too many factors go into determining calories burned that neither mfp or the machines consider. And not all machines are equal. There are two different types of treadmills at my gym at work and they are both always way off. So my advice if you opt to go without the HRM is pick one and stick with it. Don’t use both. May take longer to get results because if you pick one that isn’t effective, then you may have switch it up.

    HRM all the way! I got a polar FT4 and found out I was actually burning a lot more calories then the machines and MFP said. I am 6'4 - and I am pretty sure the stats on here doesn't take that into account. And the machines only asked for my weight and age.

    If you are serious about losing the other 50 lbs - I'd say invest in the HRM! I got mine for 89 bucks at Academy Sports... Walmart has a sportsline one for like 55.

    Most machines you can put your weight in before you start, also some have the grips to head your heart rate so that you can get a more accurate reading

  • I read online that treadmills estimate calories burned for a 170 pound man or a 140 pound woman, so unless you put in your weight it's probably not correct.

    All you need is your heart rate, and you can plug the info in here:

    I use a HRM but I do find that MFP and my HRM are very close. Example: This morning spinning, I wore my HRM and for 30 minutes, I burned 213. When I entered 30 minutes of Spinning on MFP, 218 automatically came up. I also stopped mt HRM as soon as I jumped off my bike. I know that my heart rate was elevated for a few afterwards...

    Of course a HRM is the best way to go, however I would use the machines at the gym for calories burned......I have found MFP to either be more or less on some things.

    The machines at the gym ask for your current weight so that number should be more accurate...good luck to you

    IMO there's nothing out there that's going to give you 100% accuracy on how many calories were burned while working out, but I do think using a HRM with a chest stap will give you the best calculations...I use a polar FT7 and it asks for your gender, height & weight.. You can also update your weight on the HRM I have to reflect any weight loss or gain... I'd trust it's calculations before I trust the machine or what MFP calculates...

    Assuming that the machines in the gym have the ability to put in your weight, and sometimes your age, go with the numbers on the gym machine. If it just gives a calorie readout, then the gym is probably somewhat more accurate as it will take into account actual work done on the machine ... especially if you do things like programs or change the resistance/speed/inclines/etc. frequently while working out. For example, and this is just an example, say you go into the gym and just sit on the cycle for 30 minutes watching ESPN instead of actually pedaling the thing. The gym's cycle is going to show 0 calories burned whereas MFP is likely to give you credit for 150-300 calories if you say that you "cycled" for 30 minutes. One of the assumptions that MFP seems to make is that you were in your "zone" for efficient burn and one of the things that I've found is that, especially when you are just starting off in exercise, you rarely get in your "zone" for enough time during the workout to hit the MFP suggested numbers ... although, the more that exercise, the better endurance you have and the more you start to step up your game and are able to get into that zone. By the way, don't let the statements about "zone" suggest that exercise without being in the zone isn't good. Most activity, especially most activity that makes you sweat, is a good thing no matter whether you are at peak efficiency or not.

    Of course, the best thing for figuring our your true burn is a heart rate monitor. It will take into account things like weight, height, etc. AND will also check in on your heart which gives a truer idea of how many calories you are really burning. One of the things that I was able to find out is that certain activities where I thought I was burning calories tended to yield less calories than I was estimating, while others, for the same time and similar feeling effort, yielded more calorie burn. That helped me do a better job of using my time in the gym and outside of the gym with exercise. To some extent, the HRM is same as the food scale ... it's a great friend in helping you do a better job of "estimating" and that, in the long run, is great for taking off the weight.

    I do the same thing 500 on my HRM while the machine reads 630 that is on a Arc trainer whit my weight set thats all i use
  • I use the machines where I can enter my weight, but they aren't as accurate as when I wear my HRM. It's programmed specifically for my age, weight, resting HR and is, I believe, a lot more accurate than any of the machines at the gym.
    I purchased mine at ****'s Sporting Goods for a relatively low $$. It seems to do the job well, and I don't have to guess anymore. Good luck!!

    Since I've lost weight twice now going with MFP's numbers, I'd just stick with that. Some of the estimations are definitely high, but you can adjust the time until it feels right.

    HRM all the way. If I input my age and weight into the carido machine than its a little bit closer to my HRM monitor, but its still not as accurate. The carido machine also over estimates my heart rate.
  • Thanks for all the helpful responses. Some of the gym machines let me enter weight and age, so maybe I will start using the numbers those machines give me instead of what mfp gives, because it is usually a couple hundred calories lower than what mfp estimates. Just want to be as accurate as I can and don't want to think I'm burning way more calories than I really am. Thanks again!
  • I don't know how accurate my method is, but I use a Polar FT4 Heart Rate Monitor and I start it when I start working out and then when I stop I only log the amount of time i was in the "zone." I feel I am being more fair to myself since the zone is where you wanna be to burn the fat. I have never tested it against a treadmill or anything, but I trust this brand heart rate monitor and I always round down to be safe.
