Gut, triggers and programs
Tummy scores, suspected triggers as hypotheses, and low-FODMAP and single-food programs with a safety screen.
Log how you feel next to what you ate and, over weeks, Gutlog compares the days you felt worse with what you were exposed to. Everything it finds is a hypothesis to test, never a diagnosis, and it says “not enough data yet” until there is enough.
Logging how you feel
Tell your assistant in a sentence: “tummy 7 out of 10, a little bloated”, “reflux after dinner”, or just “fine” (a useful answer: good days are half the comparison). Gutlog records bloating, pain, gas, nausea, reflux, urgency, stool form and energy with a severity, and gives each day a tummy score from 0 to 100. A note a few hours after a meal and one in the evening is plenty.
Suspected triggers
Every ingredient maps to exposures such as the FODMAP groups (fructans, GOS, lactose, excess fructose, sorbitol, mannitol), gluten, dairy protein, caffeine, alcohol, fat load and spice. For each one, Gutlog compares how you felt in the hours after an exposure with times you were not exposed, with caution built in so a handful of meals never produces a confident claim. The result is which foods look safe for you, and which don't: suspected triggers listed with how strong the pattern is and how many exposures it rests on. Trigger analysis is part of Plus.
Elimination programs
To test a suspicion properly, Gutlog runs a structured program (part of Plus):
- Low-FODMAP, in the three phases used in IBS care: elimination for two to six weeks with swaps for your own foods and a weekly check on whether you have adequate relief; reintroduction of one FODMAP group at a time over a few days, with rest days between; then personalization, back to a broad diet limiting only what caused symptoms.
- Single food: remove one suspect (dairy, gluten or any trigger) for two to four weeks, then reintroduce it and compare.
Safety first
Every program starts with a short safety screen.
- Red-flag symptoms (blood in stool, unintended weight loss, symptoms that wake you at night, fever, anemia, new symptoms after 50, a family history of colon cancer, celiac disease or IBD) mean seeing a doctor first, not a diet.
- A history of disordered eating, pregnancy, or being under 18 rules out restrictive programs.
- Every program recommends working with a registered dietitian, who can tailor it and keep it nutritionally complete.
