The C-FAST Cycle

Join Group Program

The C-FAST cycle often starts with just a few food restrictions—but over time, it can spiral, leaving you stuck and unable to see a way out.

When you are stuck in the C-FAST cycle:

  • Your brain sends false alarm signals about food, keeping your nervous system stuck on high alert.
  • Food becomes a source of stress rather than nourishment.
  • You think about food and symptoms more than you want to.
  • Grocery shopping, cooking and eating out start to feel overwhelming.
  • Your food sensitivities continue to worsen.
