Total calories different between Apple Watch and Fitbit Zip
I had used a Fitbit Zip for a while, but just recently got the Apple Watch Series 2. I switched MyFitnessPal data over to the Apple Watch on Wednesday, although I have been wearing it since Saturday. The Apple Watch calculation for total calories is always under the Fitbit projection with difference of 139 to 257:(. Anyone…
Could Fitbit underestimate my calories?
I have the Fitbit Zip, and I stand a lot instead of sitting. I really only sit down to drive when we run errands. I know that standing burns more calories than sitting. Just curious because the Fitbit seems to come out with a lower calorie estimate that what I get online with TDEE estimations.
