Silly Fitbit!

I walked about 12km today, flat landscape, mostly slow strolling with lots of photostops and a museum visit. My stupid fitbit has so far given me over 2400kcal! For a bit of walking. On a mostly sedentary workday it gets me about 1600. Silly thing! Just venting.

That's around 9 miles? so I don't think that burn sounds far away - I know when I averaged 21k steps which was around 7 miles? my burn was around 2200 (I'm 5ft 2/126lbs/49yrs)2

More like 7 miles. Usually 0.3xweightxdistance works for me. Thus not really much more than 300 extra0

This gent feels the problem is the HRM in his fitbit.

I disabled mine for a day and tend to agree as I can't find anything else to account for the high burn. FB Versa here.

I've found time spent standing vs. laying down over the course of a 24 hour day to be the major influence for TDEE (using Versa HR); steps do not seem to contribute nearly as greatly (can have a 15k step day being sedentary for most parts of the day other than active exercise barely bring me to 3,000kcal TDEE whereas I can have 12-13k step days where I stand 15-16 hours with little/no active exercise and my TDEE will seemingly/effortlessly approach 4,000kcals).
To be fair, most peoples' HR does increase ~20bpm upon standing (NEAT really is a huge/often neglected contributor to TDEE)3 -

Yes, it's likely something like this: standing instead of sitting. Having a high maxHR, the fitbit gives me quite big burns. I'd never link it to my account for that reason alone because I don't believe those numbers. Of course standing does burn some more energy than sitting, but not that much. Added to that: I spent 3 hours on the train yesterday. Just sitting on the train results in a somewhat higher HR than sitting at my desk or at home: crying babies, bumpy ride, lots of other annoyances. Thus that adds up as well.0 -
But over the course of an entire day, those minutes standing (even a measly 1kcal extra per minute) do indeed add up; it's easy for me to track due to my extreme/odd schedule/lifestyle, standing most of the day ~16 hours vs. another day laying down mostly (includes sleep) ~18-20 hours, only standing ~4-6 hours.
For this reason, I do not like tracking kcals using a set activity level; just average TDEE over the course of a 2 week period (averages out active days vs. non-active days). I really just use fitbit as a way to meet MINIMUM daily activity (steps seem fairly straightforward for my lifestyle at least)0 -

I walked 6 miles yesterday total and burned a total of 2900 calories. I find my Fitbit is super accurate2

Sure that's not Kilojoules?0

Oh wow, got 3100kcal yesterday, for a shorter walk, but dancing for 2 hours at a concert
I would believe it if I'd jumped for the full two hours. 0 -
My Fitbit gave me ~100kcal for what it thought was vigorous cycling. I was just enthusiastically petting a dog.
It gives me an extra ~300kcal for my regular non-exercise days where I walk about 3miles to work and back. The bodyweight formula gives me 108kcal and I know I'm a fast walker but really???1 -

Dancing has a MET value of 4.5. This means Dancing burns about 4.5x the calories you would burn at rest.
So 2 hrs nonstop dancing for me would be approximately 504 gross calories (NET 392).
You also went on a walk which can have a met value of 3-4.5 depending on speed. Then you have daily activity that you have to consider as well.
I’ve actually found my Fitbit gives me a Total Daily Energy Expenditure that is almost true to me. I say almost because I get away with not logging roughly 200 calories a day and still lose as expected based on my Fitbit calorie burn.3 -
Just done 25k steps earned 1162 cals saving for my birthday on Sunday 1

Is there a widely accepted MET value site or chart? I did a quick google and there are a lot to choose from.shadow2soul wrote: »Oh wow, got 3100kcal yesterday, for a shorter walk, but dancing for 2 hours at a concert I would believe it if I'd jumped for the full two hours.

I got my information from the National Cancer Institute.

And this is the site where you can find the more in depth list based on published evidence:

It'll be nice to compare my watch and activities against some hard data. Maybe answer some of my own questions

Were you petting the dog with your feet? 🤔1 -
I got tired of picking on my Charge 3 so I wore it every day for many weeks. After subtracting my carefully measured daily intake from my daily Fitbit TDEE my total weight loss for those weeks was off by a half pound.
I now wear it with confidence.
I also make sure I wear it 2 finger widths above my wrist and it is snug.0 -

More likely with the hand that has the Fitbit .. hence higher count..
One guy on the Fitbit community complaining about false reading while he was playing his bass/guitar.😂
The thing with Fitbit . It's has a sensor to count the movement.. it doesn't use gps to track you (well it does but if you use the phone gps with it)
Key important part if Fitbit is placement.. non dominant hand works best.. and change the sensor sensitivity accordingly.0 -

Dancing is my main cardio exercise. I typically average 10 calories a minute on the Fitbit (average HR in the high 120’s). I’m 6’4” and 85kg.

Weight and how you dance plays a role. I'm a lot lighter than you, and dancing should in no way burn more calories than running as usually one food stays on the ground. Unless of course I'd constantly jump the whole time.0
