Calories burned?

I've been on a diet and calorie counting since the new year and it seems like I should have lost a lot more weight. My Fitbit says I'm burning an average of 2,300 to 4,100 calories a day (mostly around the 2,700 range), and I'm now wondering how accurate it is...

When I used fitbit to lose weight I found that it was accurate as long as your profile settings (age, height, weight etc) were accurate.

 

The general guidance is that if you eat on average 500 kcal less than you burn each day then you'll lose around 1 pound per week i.e. you lose a pound for every 3500 calorie deficit. Of course, this works for the average person and not for everyone.

 

Are you logging your food in fitbit (or other compatible app)? What is your target deficit?

Well it will suddenly spike up from 2,600 one day and then 4k the next day when I didnt really do anything different.

 

Im basing my calorie intake on what I burn, so on days when it says I burned 4,100 calories maybe I should eat more so I dont go into starvation mode, but if it's not accurate then I'd be eating way more than i should . 

 

I was just wondering if anyone has had these issues with readings that dont seem quite right.
