V. 4 Symptom diary template

The diary is your compass for recovery. Fill it in once a day, in the evening – it only takes a few minutes, but the data from 90 days reveals the trend from which you and your doctor can make the best decisions. The structure of the digital diary (xlsx) is described below.

How the diary is built (xlsx)

The digital diary consists of four worksheets:

• Diary – where you fill in each day, one row per day.
• Weekly Summary – automatically totals the key metrics each week.
• Guide – questions and answers for filling it in, so that every field is clear.
• Progress – visual tracking of the trends across the 90 days.

The field groups of the daily diary

The daily row contains the following field groups:

• Basic data – date, day of the programme (1–90), phase, body weight.
• Movement – step count (target and actual), distance run/walked, type of activity.
• Fluids – fluid intake target and actual amount (litres).
• Meals – meal times and contents, length of the eating window, snacking, late eating, protein at breakfast, fibre at every meal.
• Sleep – bedtime and wake time, sleep duration (hours), quality.
• Wellbeing – hunger scale, general wellbeing, stress level, mood.
• GUT (the key CDI fields) – daily stool count, Bristol^[G] value (1–7), bloating (0–5), bloody stool (yes/no).
• Treatment – DiffBiome dose (capsules/day), LOT number.
• Body measurements – waist, hip, waist-to-hip ratio (WHR), optionally CGM^[G] value.
• Note – any unusual symptom, medication, or event.

How to fill it in

• Once a day, in the evening, fill it in once the day has "closed", so that you record the full day's data.
• Be honest and accurate – the diary works for you, it does not check up on you.
• Do not fill in missed days retrospectively by guessing; instead, write "no data".
• The note column is worth its weight in gold: write unusual symptoms, any medications, and stressful events here.

The key CDI fields – watch these most closely

If you can only keep a few fields, let these be the ones, because they show the direction of recovery or of trouble:

• stool count – how many times you had a stool that day;
• Bristol value (1–7) – the consistency of the stool (target: the formed 3–4);
• bloody stool (yes/no) – a red flag if yes;
• fever (yes/no; if yes: temperature) – a red flag if high;
• abdominal pain (0–5) – a red flag if severe/tense.
