When you rest those calories are burnt in your alimentary canal A.K.A. digestion. When you sleep it slows down.

Thank you.. That seemed crazy 

I don’t know, but it makes me want to go take a nap! 

I think it's just the number of calories you burn being alive :)  

You are constantly burning calories even when you sleep. It can be digestion, all chemical process need energy. Also, activities that you never thought burn calories actually like fidgeting. Althought not much calories but it does. 

we burn calories 24/7 the things is We burn more calories in less time if we exercise 😁 

@SoCalPam; I like your answer....I was baffled myself 

As long as your heart keeps beating you are using energy.  

Your body requires calories to function. Every heartbeat, breath, muscle contraction. My cardiologist had me go for a basal metabolic rate test where I breathed into a tube. Basically my body burns 2040 calories a day if I do nothing. After discussing with my doctors I'm eating 1600 calories a day hoping to kickstart some weight loss until I can get healthy enough to really exercise.
