Why do we weigh less after a night's sleep?

Surely you're all familiar with the phenomenom: you notice that you weigh less in the morning then you did the night before. But why? It doesn't make any sense to me. What do we lost in those 7 hours of sleep?
Note: This is assuming you don't use the washroom or eat anything between the night and morning weigh-ins.

No salt or water during the night?0

It takes a lot of energy just to meet your basal metabolic needs for your organs to function even at a low level over say 8 hours. Since you're not eating anything, you're not replenishing that energy expenditure.0

This video explains it all.

IIRC, you basically are losing weight through breathing out carbon...or something.0 -

Thanks for helping answer the question!0 -
Can't view the video on my phone, but it's mostly evaporative (water) losses, also called insensible losses, from breathing all night without taking in any liquids.0
