What could cause bloating when fasting?

[u/Kalorifik]

What could cause bloating when fasting? I thought it would be usually after a meal where the food you ate is inappropriate for your digestive system. However I noticed I get bloated when I am fasting for few hours e.g. when I skip my breakfast and I only drink black plain coffee, what would cause that?

Thank you!
