only noticed the last few days that when I get up in the morning and put my fitbit on the counter is already up to about 700-800 calories? I don't wear it in bed, but surely when it's reset the step counter etc at midnight the calorie counter shouldn't start to climb until it at least detects a heart rate?

 

I had a busy day yesterday granted but surely the watch doesn't predict a calorie burn in my sleep??

As well as tracking calories burned through activity your fitbit also tracks your BMR calories. These are the calories you burn just keeping your body alive (even when asleep). They are calculated from your profile settings for age, height, weight etc so you needn't be wearing your fitbit to get them. What you are seeing is the total BMR calories burned since they reset to zero at midnight.
