Fasting – the natural virus killer

Did you know that fasting can help your body starve viruses?

I recently tried this out after contracting the flu. I craved sugar (driven by the virus, I wondered?) but instead fasted most dasy for 17 hours as nothing else was helping. The turn around was significant, and I started feeling better quicker.

When you fast for 17+ hours, your body flips a metabolic switch

  • Blood sugar drops

  • Ketones rise (fat based fuel)

  • Autophagy (cellular cleanup) kicks in

This process removes virus-infected cells and limits the resources viruses need to multiply—especially sugar.

Recent human studies show people who fast regularly have

  • Lower inflammation

  • Stronger immune responses

  • Better outcomes in viral infections like COVID-19

Fasting literally makes the body less hospitable to viruses.

It isn’t just a weight loss tool. It’s a natural antiviral and immune-strengthening system.
