When I walk on the treadmill, it displays how many calories I burn but I know it's not accurate because the treadmill does not know how much I weigh or any of that. It's just an average, probably based on people of average weight.... and I am far from average weight. So how do I ACCURATELYcalculate how many calories I burn while walking?

    I have the Polar FT4F heart rate monitor. Works great on accurately showing me how many calories I have burned. You set your setting with height/weight/age. Other than that you are always going to get some average/guess on how many calories you are burning.

    Sorry JenMarie- only way to know for sure is to get an HRM. Burn varies so much person to person depending on so many different things. Best to get an HRM with a chest strap so that you know exactly what you're burning.

    Heart rate monitor is your best bet.

    I am not an exercise expert but the only way I get a true reading is from my HRM. I got the Polar ft4.

    I have the Polar ft7... it does what i need... I am not a runner, so I didn't need a gps... Hope that helps...

    That is a good question!! My is the same way, it doesn't know my weight either. And I have been going by that but never thought about it!!
    I bought me a watch that reads my calories when I am doing the wii, maybe I will use that one for me.
    Maybe you should get one too! It runs between $30 to $60 at Kmart. I got the one in the middle.
    Good luck! And thanks for bringing it up!!! It got me thinking! LOL

    ok so i have a question now....at my gym I use the elliptical machine and i enter my weight, age and time.. I keep my hands on the sensors so it reads my heart rate..would the calories burned be accurate then?

    the only way to know FOR SURE is to measure the CO2 you breathe out. I have done this for an exercise study. 99.99% of the time, you can't do that.

    The second best way is a heart rate monitor.

    Don't trust the number on the treadmill. it is notoriously and sometimes wildly inaccurate.

    A heart rate monitor might not be in the budget. In that case what I have found is that if you look at all the calories estimators, you might find they are fairly close. MFP has one where you log your exercise:
    Click Exercise, Under cardiovascular click add exercise, click the treadmill and then enter your minutes. Let MFP consider your weight and burn.

    I have an elliptical that does ask for my weight and I find that it and MFP are close enough. They also somewhat agree with another website I use that calculates my burns.

    What I found myself doing was under-estimating my eating calories and over estimating my burns. No wonder I was not losing weight. When I reversed that and started to be more realistic, the weight started coming off. If you are trying to cut it too close by having perfect numbers, I think your progress may be slower than you would like. Just a thought.

    it *might* be accurate, but you're trusting that the manufacturer is correctuly using your input to calculate calories. And studies have shown that those machines notoriously overestimate your calories burned.

    I have noticed that the elliptical I use at the gym gives me a very low number..and when I get off it I feel like I burned twice the amount it gives me! I think I will take my calorie reader there too just to make sure I am getting an accurate read. If the machine can't really be trusted.

    You will never know for sure how much you take in and how much you burn. It's all (quite accurately in some cases) guessed.

    I have the same question about my new pedometer. I'll repost after my workout. Will my pedometer and elliptical have the same reading?

    This. Contrary to popular belief, HRMs are not a perfect measure of how much you're burning. They're actually quite inaccurate in some cases (e.g., strength training). You can approximate more or less closely, but in the end as long as you're in the right ballpark most of the time, you'll be fine.

    I have a BodyMedia Fit (Same maker as a BodyBugg):bigsmile: and I love it! It tells me how many calories I burned in a 24 hour period.

    The military teaches navigation (field navigation that is) to deliberately aim off. For example, I want to get to the crossing of two roads on the map, instead aiming to the intersection, I'll aim half mile to the left, that way when I hit the road I KNOW that i have to turn right for the intersection. Even if my navigation is poor, and I end a quarter mile off from the point I wanted to get to, the intersection is still to the right.

    When in doubt with things like calorie measuring, apply the same principle to "err on the right side". Don't know if the machine is programmed for an average man, average woman, fat man, skinny woman?... no problem. HALF what it says, and record that. At least you know for sure you worked off that many calories. The rest (whatever it may be), chalk it up to the cost of accuracy. Over time, those will be an unexpected bonus, especially when you weigh in at the end of the week and realize that you lost more than you calculated you would :)

    Hope this helps.
