Logging Exercise Using MFP Calculations or Not?

I haven't been logging my twice daily 20 minute walks because I don't trust the calories MFP says I burn. They just seem pretty inflated. Does anyone else not track their exercise if they're not sure about the calories? I figure I'm pretty spot on with tracking my food, shouldn't exercise be the same way? I have been doing T25 and before that I was doing Insanity...I always wear my HRM for these so my calorie counts are accurate. I'm trying to see how everyone else does it...If you know your calculations aren't right, do you still eat back those calories? I typically do, but I know mine are right. I don't know if I would trust eating them back if I wasn't sure. Thanks!!

    Before I got my HRM I still tracked the exercise, so I could personally keep track of what I was doing. I never ate the calories back tho. I have also noticed that my HRM is about half of what MFP estimates. So you could always change the entries yourself and enter half of what MFP is stating :)
  • That's a good idea...I may consider that! Thanks!
  • Looks as if the calories burned are doubled.

    I track the exercise calories that the treadmill or other equipment says but just because I told one of my friends when I work so hard I want to see high #'s... just ego but I don't eat back my calories so it doesn't matter to me if they're inflated. Whatever works for you is the right answer:flowerforyou:

    I dont trust it. I have a garmin with an HRM and i use it instead.

    So I use MFP for 1 source, than I use my RUNKEEPER phone app to track all workouts, and finally i use my POLAR F7 HRM. I will look at all 3 and kinda use a avg between the 3.

    Just a heads up RUNKEEPER is a free app. Also you can link the account with MFP and they will update your info on both sites as you use it.

    Before my HRM arrived, I was recording MFP info but felt it was too high so I didn't eat back more than about 30% of the cals. Now that I have the HRM, a FT4, I am using that no. of cals as my cals burned as I think it is much more accurate. Now I will eat by cals on the day I feel I need them. Many days, I don't go into my exercise cals at all. YMMV.

    I'm really confused. I have seen several people talk about eating the calories they burn back. Are you suppose to do that?
  • I use UP by Jawbone (a lot of other people use Fitbit) to track my calories burn and have it adjust my calories. I was shocked to see the difference in calories. Sometimes MFP estimates TRIPLE the calories burnt than my UP band. I definitely wouldn't trust MFP if your'e planning on eating back the calories.

    Ya, where on earth does MFP get these estimates from??

    My buddy logged an hour of "Gardening" and it said he burned like 1000 calories! Ummmm ok right!

    I didn't eat back the MFP exercise calories burned; I've been using a HRM for sometime and I agree with many of the posts about the significant difference between MFP and the HRM.

    Is your buddy really heavy? I get 258 if I were to log an hour of gardening.

    When you set your goals, you indicate whether you are sedentary, active, etc. You also give your weight loss goal (1 pound per week, etc.), as well as your expected level of workouts (15 minutes daily, etc.). From that information, MFP calculates your normal daily caloric consumption, and then sets your target caloric intake to meet that weight loss pace.

    If you do more workouts than that, you are burning more calories than they calculated. E.g., if you say you are sedentary, but then you start working out every day, that workout is not calculated into your MFP projections. So you can eat back some of the calories you consumed in your workout, and still be on target for your weight loss pace. But if you say you are active, and you remain equally active, then MFP has already calculated that into your projections.

    So go back and check what your answers are on your goals. Then you can decide whether your activity is already incorporated into the MFP goals (in which case you do not eat back), or whether your activity is in addition to the MFP goals (in which case you can eat back if you choose).

    if you have a hrm just use it with your walks and then you dont have to worry if mfp is correct or not

    98% of the time I manually adjust MFP calories burned downward by about a third from what MFP gives me.
    Just manually lower the number.

    My HRM estimates for calories burned for walking, kickboxing, softball games are all higher than what MFP lists FWIW

    I use a fitbit and let it sync. Fitbit burn is about half of the MFP calories.

    I agree it seems inflated. I list haying as "gardening" and stall cleaning with a pitchfork as "heavy cleaning", and cleaning the duckhouse and rebedding as "light cleaning" or not logging it at all. There is nothing in the exercise database for either mucking stalls or haying. I don't have a HRM and can't afford to get one; I need a second hay baler a lot more.

    I don't use MFP numbers other than for swimming since I don't have a waterproof HRM. Otherwise, I use my HRM's number (which is typically lower), AND I calculate net calories burned (only the amount I burned over and above what I would have burned anyway even if I had been sitting on the couch). High numbers are fun, but I feel like what I'm doing is most realistic. But then, I don't typically eat them back anyway.

    I assumed MFP got it's estimates from info logged by other users which is stored in their database, but I could be wrong.

    I have only just joined MFP but I am not going to trust their figures as I done a cycle yesterday which MFP said was close to 1400 calories but my HRM said 1100. Conversely I did C210K wk1 d1 earlier this week which MFP added up to 421 cals but my HRM said 407 so that wasn't that far out.

    As other people have said it is probably best to use a HRM where possible but under estimate MFP figures when there is no other choice, like when I go swimming I will take off a third of MFP figures.

    I only lift weights 3X a week and just skip logging the calories. It wouldn't be that much of a difference anyway, & I just look at it as a slight bump up in my caloric reduction/deficit for the day.

    I adjust my calories burned manually to be where I need them, since I do eat them back.

    Basically I maybe only log 1/2 of what MFP says. Another great option it to just go with TDEE method, then it really doesn't matter what calories you burn. You'll know exactly how many calories to eat each day.

    I don't think that MFP's numbers for walking are inflated. If anything, they're lower than the calculations on other sites. MFP also lowers your calories burned when you walk the same distance more slowly. Most sites give you about the same burn per mile.

    It really does depend on weight and fitness levels. MFP calcs usually are 20% above my HRM.

    Other sites are no more accurate than MFP - they're norm based, and individuals will vary from the norm.

    For distance based exercise, 100 cals per mile is the average burn. This is perhaps the best way to estimate cal burn for walking and running - add a bit for running to allow for the difference in effort, and a bit more for weight.

    That supports my general feeling that MFP is not inflating the numbers for walking. MFP gives me 59 calories per mile of walking, and less if I walk slower than 4 mph. Individuals may deviate from that norm, but for an average burn dependent on total body mass, it seems right on.

    If I have a more accurate reading, I correct to that figure. Have found mfp to consistently over count calories that I have tracked on gym equipment. Otherwise I just halve the mfp calories.
