Elimination Diet Tracker Calculator

An elimination diet involves removing common trigger foods from your diet for 3–6 weeks and then reintroducing them one at a time to identify which foods cause symptoms. The elimination phase typically lasts 3–4 weeks, followed by a reintroduction phase where each food is tested over 5–7 days. The entire process can take 2–3 months depending on how many foods you test.

A score of 0 means no symptoms at all, while 10 represents the most severe symptoms you have experienced. Mild discomfort such as slight bloating or a minor headache might score 2–3, moderate symptoms like noticeable digestive upset or fatigue score 4–6, and severe reactions such as hives, significant pain, or extreme fatigue score 7–10. Consistency in your scoring is more important than exact values.

The Reaction Risk Score compares your current phase symptom average to your baseline symptom level during the elimination phase. A score above 5 suggests a meaningful reaction to the food being reintroduced, while scores below 3 generally indicate the food is well tolerated. This is a guideline tool — always consult a healthcare provider before drawing firm conclusions.

Most elimination diet protocols recommend waiting at least 5–7 days between reintroducing each food. If you experience a reaction, return to the elimination diet until symptoms resolve (usually 3–5 days) before testing the next food. This washout period ensures that lingering symptoms from one food do not confuse your assessment of the next.

The most commonly eliminated foods are dairy, gluten/wheat, eggs, soy, corn, nuts and seeds, nightshades (tomatoes, peppers, eggplant), legumes, citrus fruits, and alcohol. Some protocols also eliminate added sugars, processed foods, and caffeine. Your healthcare provider may adjust this list based on your specific symptoms and history.

Yes. The calculator uses your day-by-day symptom scores and your personal baseline to generate a reaction risk assessment, so it works regardless of which specific foods you are testing or which protocol you follow. Simply enter the number of phases matching your plan and log your symptom scores each day.

It is strongly recommended to work with a registered dietitian or physician before starting an elimination diet, especially if you have a history of allergies, eating disorders, or nutritional deficiencies. Eliminating multiple food groups simultaneously can lead to nutrient gaps. This calculator is an informational tracking tool and does not replace professional medical advice.

Day-to-day symptom variation is common and can be caused by factors unrelated to food, such as stress, sleep quality, hydration, or hormonal changes. That is why the reintroduction window is 5–7 days rather than a single day. The calculator averages your scores across the phase to reduce the impact of isolated spikes and give a more reliable overall picture.
