Why does my belly get super big and squishy after fasting for 16+ hours?

Hey everyone! I’ve been doing intermittent fasting (16:8) almost every day for the past two weeks. I'm doing it for health reasons, I'm pretty happy with my weight. Overall, it’s been going well, but I’ve noticed something weird happening with my belly after about 16 hours of fasting.

It starts getting bigger but feels super squishy. It’s not bloated (no discomfort or tightness), and it doesn’t feel like fat because of how oddly soft and mushy it is. The sensation is kind of strange, and I’m wondering if anyone else has experienced this or knows what’s going on.

Thanks in advance!
