Overstated Calorie Count

Don't use any of the Map My apps if you want to accurately count calories. They typically count about 50% for than other apps e.g. with a Map My app you will burn about 300 calories during a 2 mile walk. Most other apps and exercise fitness experts will show about 200 calories burned during a 2 mile walk.

    I've found the same thing. I just use MapMyHike to record distance and time. Then I use a different calculator here on the interwebs.

    For walking try
    (Weight in lbs x 0.3) x distance in miles =cals burnt.

    And compare to the numbers you are getting from apps/devices.

    Or 8 calories per minute.

    So what do you use? I'm using UA record

    Or 8 calories per minute.

    That ignores walking speed. I often walk up to 4.5 mph but sometimes only 3.5 or so.

    Actually, it ignores distance. Calorie burn for walking and running is largely a function of distance (and weight). You don't burn a lot more calories regardless of walking 3.5mph or 4.5mph. If both result in a 5 mile walk then the calorie burn is fairly similar.

    You are right but it gives you a decent ballpark to compare to. It won't be dead accurate but what method is?

    That's true, but say you walk one hour at both speeds then one would result in a total of 3.5 miles walked, the other in 4.5 miles. For a person weighing 160lbs the calorie burns would be about 168 and 216 respectively. For me (ok, I'm lighter) that would be a difference between having a wafer bar (100kcal) for my workout or two :D

    IIRC, that number was based on a 4 minute mile in a calculator I saw some time ago. But I wouldn't stake my life on it. Yes, for someone lighter, it would make a bigger difference. For me at 182 lbs and eating 2200 to 2500 per day, inconsequential. So, decent ballpark for me. Not so hot for you.

    Map my run seems fairly accurate to me. 400 cals for an hour run is reasonable? It is based on pace also so when I run faster I get more cals expended per hour. Please don’t burst my bubble :#

    running at a ~typical speed is about 0.63 calories x weight in lbs x miles. (which does work out to pretty much exactly what Garmin gives me for a run). That comes pretty close to 400 calories per hour for me if doing a slower group run with traffic/wait stops (10-11 min average pace).

    myfitnesspal seems to give an accurate calorie estimate for me for walking. I pick between 2.5 or 3mph settings and input my time. I have been using it for over a year with success.

    I cannot comment on MapMyRun specifically, but in general, running faster *is* more calories per unit time! But it is also less time for a given distance. Most calculators give me essentially the same kcal/mile (within 10 calories) whether walking 14 min miles or running 7 min miles. It doesn't seem fair, does it? Running is def more effort, at least for me it is. But it's half the time spent exercising, too.

    My Fitbit actually gives me MORE calories for going slow. I think it is because Fitbit counts BMR in the elapsed time, i.e. the burn includes BMR for 56 min for 4 mi slow, which is twice the BMR for 28 min for 4 mi fast.

    Vast majority of calc's and database methods will also include BMR though.

    Which is correct - here's the estimated calories burned during this chunk of time doing whatever you were doing. More time at low level calorie burn, more % is BMR.

    The reason the Fitbit gives higher, is probably because it's using HR-based calorie calculations, and at the extremes of that formula - right above daily activity, and right below anaerobic intensity - the calc's will be inflated.
    When HR-based is a decent estimate - it's in the middle of the range of clearly aerobic steady-state cardio.
    Anything outside that range is even more inflated.

    That's why Fitbit using HR-based for clearly daily activity stuff will cause inflated calories - and they try to minimize that by getting a handle on when it appears you clearly go into exercise levels.

    You're making a distinction without a difference. Ignoring distance is exactly the same as ignoring speed, since distance = speed x time.

    Interestingly, Fitbit gives me the fewest calories for exercise when compared with the MapMy products and MFP. The individual MapMys (MapMyWalk, Run, Hike) are the highest. It seems like it shows both the calories you burned while exercising and the calories you would have burned anyway. MapMyFitness send to do a better job of just showing the additional exercise calories and usually matches with what MFP would give me. Fitbit gives me the fewest. Not off by much but still lower. It might help that I am using the Alta and not the Alta HR so it isn't conflating from unrelated increases in heart rate.
