Four columns, two weeks
Record: (1) foods and drinks with the time; (2) symptoms with time and a 1–10 severity; (3) sleep hours and quality; (4) a quick stress note. Two weeks is usually enough to expose repeatable patterns without becoming a chore you abandon.
When a journal earns its effort
Before or during an elimination diet, when symptoms seem food- or timing-related, or when you simply can't tell whether it's diet, sleep, or stress driving how you feel. It turns vague impressions into evidence you and your clinician can read together.
Why most food journals fail
Skipping the clock (so delayed reactions stay invisible); logging food but not symptoms (or vice versa); over-engineering it into something too tedious to sustain; and forgetting sleep and stress, which confound everything. Simple-but-timestamped beats detailed-but-abandoned.
Why timing is the signal
Non-allergic food reactions are typically delayed — hours, not seconds — which is exactly why memory fails and timestamps succeed. This is the same principle behind clinical elimination-and-reintroduction: attribute the effect to the input by controlling and recording timing.
Your next step
Start today — paper or phone, whichever you'll actually keep — and bring two weeks of entries to your visit. We'll read the pattern with you: book an appointment or use the Care Path Finder.
Quick answers.
Do I need an app?
No. A notes app or a pocket notebook works fine. Consistency and timestamps matter far more than the tool — the best journal is the one you'll actually keep for two weeks.
What if I don't see any pattern?
That's useful information too — it points away from food and toward sleep, stress, hormones, or blood sugar. A 'no clear food pattern' journal helps us redirect the workup instead of chasing the wrong cause.
