Food Symptom Diary: How to Find Trigger Foods in 14 Days
A food symptom diary is one of the highest-leverage tools for people with recurring bloating, fatigue, headaches, or mood swings after eating. The key is not just logging food. The key is logging the right variables with a clear method.
What to Track in a Food Symptom Diary
- Meal time and meal composition
- Symptom type and severity (1-10)
- Onset timing: immediate, 2-4 hours, or next day
- Sleep quality and duration
- Stress level and activity
- Caffeine and alcohol intake
14-Day Trigger Food Protocol
- Days 1-4: Track baseline without changing your diet.
- Days 5-11: Remove one suspected trigger category.
- Days 12-14: Reintroduce once and watch for symptom return.
How to Read Your Data Correctly
Look for repeated symptom spikes linked to one category over multiple exposures. One bad meal is not enough to conclude causality. Two or three consistent signal points usually means you found a real trigger.
Common Diary Mistakes
- Logging once at night from memory
- Changing too many variables in the same week
- Ignoring stress and sleep data
- Stopping the process before reintroduction
Turn Logs Into Decisions
Burn combines meal logs, symptom check-ins, and experiment tracking so you can move from "I think this is causing issues" to "I have evidence this is my trigger." That speed and clarity is what improves compliance and outcomes.
