The Blood Sugar Rollercoaster
If you feel like cravings control your day, you’re not alone.
Many people think cravings are about discipline. But often, cravings are driven by something physical: blood sugar spikes and crashes.
The pattern:
Spike → crash → craving → repeat
When blood sugar drops quickly, your body sends strong signals to eat fast energy — usually sugar or carbs. This isn’t weakness. It’s biology.
Signs your cravings may be blood sugar related
- Craving sweets after meals
- Needing snacks every few hours
- Afternoon energy crashes
- Late-night hunger
- Feeling shaky or irritable when hungry
Simple ways to reduce spikes (without extremes)
Start with these:
- Stop grazing all day (create space between meals)
- Protein first (helps cravings and stability)
- Reduce ultra-processed sugar frequency (even small reduction helps)
- Consider structured fasting (gentle, realistic, safe)
When blood sugar stabilizes, cravings often become quieter. Not overnight — but steadily.
My turning point
For years I lived in cravings → constant eating → weight gain → exhaustion → starting over.
When I focused on blood sugar habits instead of just calories, everything started to shift. Hunger stabilized. Energy improved. My A1C improved. I lost over 130 pounds.
You don’t need perfection.
You just need a calm place to start again.
