  • Abdominal pain
  • Loss of appetite
  • Bloating
Quick start checklist

Common triggers to track

These ingredients often show up in patterns—worth checking first.

Recommended 2-week workflow

Follow these steps to get meaningful data.

1

Start with a gentle baseline and log what you eat for 7 days.

2

Note energy, sleep, hydration, and medications alongside each entry.

3

Use the FODMAP checker to tag high fermentable ingredients if bloating is prominent.

4

Use the histamine checker on aged or fermented foods if reactions feel rapid.

5

Keep portions small and consistent for 3 to 4 days before changing foods.

6

Reintroduce one change at a time and keep notes on recovery time.

Example scenario

Example: You keep portions small for 4 days and note whether nausea shifts. You then test one higher fiber food to see if symptoms return.

Common mistakes

Avoid these so your results stay clear.

Making big diet changes during a flare.

Skipping hydration or medication notes.

Expecting day to day symptoms to be consistent.
