Elimination diet tracker
Most people doing elimination diets rely on printable PDFs and messy spreadsheets. You deserve better. OutLast is the elimination diet tracker that lets you log what you eat and how it makes you feel — so you can identify your trigger foods and reintroduce with confidence.

The problem
You're in the elimination phase but can't remember exactly what you ate when a symptom appeared — your notes are scattered across PDFs, notebooks, and spreadsheets
Reintroduction is the hardest part — you need to track one food at a time over multiple days and watch for delayed reactions, but paper logs make this nearly impossible to review
Most food tracking apps focus on calories and macros, not symptoms and reactions — they weren't built for elimination diets
OutLast makes it simple: log what you eat and how it makes you feel. Track elimination and reintroduction phases. Spot your trigger foods with real data instead of guesswork
How it works
During elimination and reintroduction, log what you eat and tag any symptoms — bloating, fatigue, headaches, skin issues. It takes seconds and builds a clear food-symptom timeline.
When you start adding foods back, log each reintroduction and monitor for reactions over 3 days. OutLast keeps everything organized so you never lose track of where you are.
After your reintroduction phase, your data tells the story. See exactly which foods caused reactions and which ones are safe — no more guessing or re-eliminating unnecessarily.
What you get
Log your way through both phases of the elimination diet. Tag meals as baseline or reintroduction and track symptoms alongside every food you eat.
Bloating, fatigue, headaches, skin flare-ups, brain fog — log any symptom and connect it back to what you ate. Catch delayed reactions that paper logs miss.
The gold standard for reintroduction is one food every 3 days. OutLast helps you stay organized so you know exactly which food caused which reaction.
Your elimination diet generates weeks of food and symptom data. OutLast makes it easy to look back and see which foods consistently trigger symptoms — and which are safe.
The science
What people say
“I tried tracking my elimination diet in a spreadsheet and gave up after a week. OutLast made it so much easier — I just log what I eat and how I feel. Found out gluten and dairy were my triggers within a month.”
“The reintroduction phase was where I always failed before. I’d lose track of which food I was testing and when. With OutLast I could see everything in one place and finally finished the process.”
“My functional medicine doctor recommended an elimination diet but I couldn’t find a good app for it. OutLast isn’t specifically an elimination diet app, but it’s perfect for logging foods and symptoms side by side.”
