Why do I feel so energetic after skipping morning meals?

When you stop eating for a while, your insulin levels drop, which signals your body to start burning stored fat for energy instead of glucose. I noticed the same mental clarity when I stopped snacking late at night. Digestion takes a massive amount of energy, so your brain benefits directly.

I use that timeline to track my own digestion breaks on busy weekends. It is truly fascinating.
