Why Blood Sugar Can Bend Your Mood
Your mood is not separate from fuel; the brain is an energy-hungry organ all day.
The Science
- A sweet rush alone can spike blood sugar and then crash it, which can feel like irritability or fog.
- Fiber, protein, and movement smooth the curve, so energy arrives more slowly for the brain.
- This is about giving mitochondria and insulin an easier problem, not guilt or dieting.
The Protocol
- Pair the sweet thing with fiber or protein instead of eating it alone.
- Take a ten-minute walk after a meal when it fits the day.
- Notice your mood and energy patterns without turning food into shame.
