Conditioned Food Avoidance & Sensitivity Trap (C-FAST)
I created the C-FAST cycle to show how people get caught in restriction and worsening sensitivities.
When you are stuck in the C-FAST cycle:
I have summarized the basic concepts in the Simplified C-FAST diagram.
If you want more details, please watch the video below. We explore how Janet got stuck in this vicious cycle.

Misconceptions About Conditioned Food Sensitivity
Conditioned food sensitivity is not:
- “In your head”: Medical professionals often dismiss their patient’s concerns and may suggest the patient is exaggerating their suffering. However, conditioned food sensitivity causes debilitating, physical symptoms.
- A person’s fault: Most people suffering from mysterious symptoms get very little support from the medical system, which leaves them vulnerable to the fearful food messages that fuel the Food Avoidance & Sensitivity Trap. Conditioning is an unconsciously learned reaction.
- Permanent: You can change the automatic reactions that are causing your conditioned symptoms.
- The sole cause: In many cases, both conditioned and physically-driven reactions (e.g., celiac disease, food allergy, etc.) contribute to an individual’s food sensitivities.
Conditioned Food Avoidance & Sensitivity can devastate your physical and mental health, making you feel:
Frustrated by an endless cycle of elimination diets.
Hopeless that you will be on a restricted diet forever.
Scared to eat.
Angry that you cannot enjoy food like other people.
Alone because your restricted diet makes socializing difficult.
Exhausted because your life revolves around food.
Confused about what you should and should not eat.
Worried that you are not getting adequate nutrition.
