Is Fitbit even accurate during pregnancy?

[DracoLinfield]

I'm using Fitbit since 2.
In pregnancy you need anywhere from 2 to 300 extra calories and are burning more because your heart rate goes up and a number of other variables that make your metabolism different during pregnancy. is Fitbit even capable of acknowledging this with just the skin and heart rate sensor? Or is it simply inaccurate because their math is not accounting for the right formula that should be used for pregnant women. Also, why is there no women's health forum not everything is menstrual health that's honestly just ridiculous. This is a pregnancy topic. Why don't you even have that category? Do you no women work here?

Fitbit should be able to account for additional calories burned since the heart rate increases during pregnancy. That will be the only difference it will account for, though. I used to work at Whoop as an analytics specialist, so I have a very thorough understanding of how the technology works for devices like this, and majority of calorie counts on devices like this are incorrect as it is. The simplest explanation: the body burns calories in different ways--for example, the thermic effect of food--which cannot be accounted for as calorie burn is estimated based only on heart rate. Calorie counts on fitness trackers should always be taken with a grain of salt, and they are also often inflated. I hope this helps, and congratulations on the pregnancy!
