App counts too many calories

[LokeAa]

If you go for a fast power walk, you can burn three hundred calories per hour. The first screenshot is from yesterday, autodetected walk. I was walking in the sense I was moving one leg in front of the other, but it was a slow stroll for 1h 8m. According to the app, I burned 519kCal

The second screenshot is from this morning’s treadmill workout. 45 minutes, twenty-nine of them in the peak zone. According to the app I burned 469 calories. Having in mind most people cannot burn more than six hundred calories per hour regardless intensity of whatever exercise one does, 469 is probably too many.

I am trying to gain weight, not loose, so it does not matter to me, but for those struggling to lose weight counting on Fitbit is giving them a correct estimate of how many calories they burn in a day, this is a severe error.

1)  The first walk says it was 1h 28m, not 1h 8m, burning average 5.9 cal/minute.  But I am not sure how that is relevant to your point.

2) I guess your point is that averaging 10.7 cal/minute on treadmill for 45 minutes, with 29 minutes in peak zone, seems unreasonably high to you.  To me, that's does not look unreasonable.  Of course weight is a big factor in calorie burn.

I guess your comparison basis is 300 cal/hr for power walk, I suppose taken from some web calorie calculator.  And I have no idea what kind of person it is talking about.  And I doubt their idea of a power walk does not mean getting close to peak heart rate zone.  Calorie burn can increase quickly when getting into higher heart rates.

I have not used a calculator. It is from a study by professor in training physiology Lars Nybo, University of Copenhagen. Most people are able to burn 600 calories per hour. If one is very fit one thousand per hour. Somewhere in between . It says 1 hour twenty-eight is correct, doesn’t matter. I «walked» 2,5 km, hardly any more effort than standing still.

Treadmill workout, I was in peak zone 21 min. Around 600 would be more or less accurate If I had been in peak for 45 min.
