i haven’t eaten in two days

Intentionally, of course.

The number one thing that fasting has taught me is that I’m pretty much never hungry; at least in the sense that I think I am. It’s been two days without a single calorie consumed, yet I have plenty of energy. Why is that at noon on any average day I feel like I need to eat?

It’s mostly psychological. The body finds a way to keep going—the sugary shit I eat all the time just makes me feel like I need it.
