The short answer

Log every meal and symptom, compare the days you ate each food with the days you didn’t, then test the top suspect with an elimination. By hand, that takes weeks. GutSync does all of it from one sentence a meal, and most people see their first pattern within a week.

What to log

What an IBS food diary should track.

Six things. In GutSync, each one takes a sentence.

Or just text it to GutSync
  • Meals and drinks
    What, how much, when. Every food gets tagged by trigger family automatically.
    Log itOat latte and a croissant at 8
  • Symptoms
    What hit and when. The timing is how GutSync ties a flare to the meal behind it.
    Log itBloated and crampy by 11, pretty bad
  • Bowel movements
    Bristol type 1 to 7, in plain words. The first thing your GI asks about.
    Log itRough morning, type 6
  • Sleep and mood
    Bad nights and brutal weeks cause flares too. GutSync makes sure food doesn’t take the blame.
    Log itSlept 5 hours, stressed about work
  • Medications and supplements
    Antibiotics, probiotics, fiber. Every one tracked as its own suspect.
    Log itTook my probiotic with breakfast
  • Life context
    Travel, illness, your period. GutSync checks the whole week before it blames a food.
    Log itFlying to Denver Thursday

Why it’s hard

Why IBS triggers are hard to spot by hand.

Diaries fail for four reasons. GutSync fixes all four.

How the math works
Reactions arrive late.

By hand

A diary blames whatever you ate last.

GutSync

Every food gets its own reaction window, from 2 hours for caffeine to 2 days for the slow ones.

Foods travel together.

By hand

Garlic, onion and wheat share a plate. All three look guilty.

GutSync

GutSync untangles suspects that share a plate, so garlic doesn’t take the fall for onion.

Everything else moves too.

By hand

A week of bad sleep gets pinned on Tuesday’s pasta.

GutSync

GutSync checks your sleep, stress and cycle before it blames a food.

Generic lists aren’t yours.

By hand

You cut every food on the list and still flare.

GutSync

Every food is scored against your own baseline. The list you get is yours.

What you get

Your triggers and your IBS pattern, read for you.

Every food scored against your history. Your Bristol log read as IBS-C, IBS-D or IBS-M.

How GutSync works

Four steps. You only do the first.

You tell it what you ate. GutSync does everything else, around the clock.

Take the full tour

  1. You log

    Log a meal in one sentence.
    Type it, say it, snap it or text it. GutSync handles the rest.

  2. It measures

    Every trigger comes with a number.
    Every food scored against your own history, with the proof attached.

  3. It investigates

    Suspect a food? Put it on trial.
    GutSync runs the elimination on autopilot and won’t stop until there’s a verdict.

  4. It remembers

    Generic on day 7. Specific on day 60.
    It knows your history and pings you the moment the evidence moves.

Questions

IBS diary questions.

“I’m an M2 with ulcerative colitis, so I’ve read plenty about what GIs actually want to see in a patient diary. The Bristol-aware export is honestly the first one I’d trust without second-guessing it. Before my last colonoscopy it saved me hours of trying to rebuild my flare history from memory.”
