Why doesn't Nutracheck show all the calories my Fitbit says I've burned?

Nutracheck already factors BMR (basal metabolic rate) calories into your calorie allowance. So when we pull the calories burned figure from your Fitbit, we only count actual exercise you have done or steps taken. If we imported all BMR calories burned, there would be an element of double counting and we want to ensure that the calories burned figures used are in your best weight loss interest i.e. not overstated.
