"Try weighing yourself before bed and when you wake up. You'll find you lose a pound or more for exhaling carbon in your sleep" I've tried this a bunch of times and have seen up to two pounds difference on rare occasions! A significant fraction of the weight loss is due to water loss though. (and technically it's carbon dioxide, not "carbon", although with climate change being blamed on "carbon" we may have already lost the war on that misnomer!)
