Formula Used
Each input is converted to a 0-100 subscore. The overall score is a weighted average.
| Dimension | Weight | Notes |
|---|---|---|
| Plant diversity | 15 | 30 plants/week reaches 100. |
| Fiber | 15 | 10 to 0, 35 to 100, capped. |
| Fermented foods | 10 | 7 servings/week reaches 100. |
| Added sugar | 5 | 0 to 100, 50g to 0, floored. |
| Ultra-processed foods | 5 | 0 to 100, 6/day to 0, floored. |
| Sleep | 10 | 5 to 0, 8 to 100, capped. |
| Stress | 10 | 1 to 100, 10 to 0, floored. |
| Hydration | 5 | 2.5 L/day reaches 100. |
| Activity | 5 | 150 min/week reaches 100. |
| Antibiotic disruption | 10 | No=100, Yes=40 short-term. |
| Symptoms | 10 | Regularity 60%, bloating 40%. |
How to Use This Calculator
- Estimate your typical week, not a single perfect day.
- Enter plant variety, fiber, and fermented servings first.
- Add sugar and ultra-processed servings based on labels and habits.
- Include sleep, stress, hydration, and movement for context.
- Press Calculate Score to view results above.
- Use the tips, then re-check weekly to track progress.
What the score represents
The Microbiome Balance Score summarizes your inputs into a 0–100 indicator of gut-supportive patterns. It combines diet variety, fiber density, fermented foods, and lifestyle stability. Higher scores generally align with more consistent routines and fewer disruption signals across the week. Each subscore is capped at 100 so one strong habit cannot hide weaker areas.
Diet signals used in scoring
Plant diversity and fiber carry the largest diet weights (15% each), because variety and fermentable substrates support microbial activity. The calculator treats 30 unique plants per week as a 100-point target and scales proportionally below that. Fiber is scored from 10 g/day (0 points) up to 35 g/day (100 points), then capped. Fermented foods contribute 10% and reach full points at 7 servings per week. A serving can be 1 cup leafy greens, 1/2 cup beans, or a small handful of nuts. Added sugar trends toward zero near 50 g/day, and ultra-processed servings fall quickly beyond about 6 per day. Both dimensions are weighted at 5% each.
Lifestyle and stress factors
Sleep and stress contribute 10% each to reflect how recovery and nervous-system load can influence gut comfort. Sleep is scaled from 5 hours (0) to 8 hours (100). Stress is self-rated from 1 to 10, where lower stress earns a higher subscore. Hydration and activity add 5% each; 2.5 liters/day and 150 minutes/week reach full points. If unsure, count only deliberate exercise minutes for consistency.
Medication and symptom adjustments
Recent antibiotics apply a short-term disruption factor (10% weight), set to 40 points when used in the last three months. Symptoms contribute 10% using a blended score: bowel regularity (60%) and bloating frequency (40%). This does not diagnose conditions; it shows whether comfort signals match the habits you report and helps you identify practical next steps.
How to interpret and track results
Use the band label as a trend marker rather than a verdict. If your total is below 60, prioritize one improvement for two weeks, then reassess. High-impact changes include adding two plant foods daily, increasing legumes twice weekly, or replacing one ultra-processed snack. Rechecking weekly helps you see whether your score moves with routines, not random daily variation. Review the lowest two subscores first, then export CSV or PDF to compare week-over-week progress for clearer long-term decision making.
FAQs
1) Is this score a medical diagnosis?
No. It is an educational estimate based on reported habits and symptoms. It cannot diagnose gut disorders or infections. Seek clinical care for severe pain, bleeding, persistent diarrhea, or unexplained weight loss.
2) How often should I calculate my score?
Weekly is ideal. Microbiome-related habits change gradually, and weekly tracking reduces noise from one unusual day. Use the same time window each week for a fair comparison.
3) What counts as a unique plant?
Different fruits, vegetables, legumes, whole grains, nuts, seeds, herbs, and spices count separately. For example, oats and brown rice are two uniques. Mixed dishes can add multiple plants if ingredients differ.
4) If fermented foods upset my stomach, what should I do?
Start with small portions, choose lower-lactose options, or skip them temporarily. You can still improve your score through plant variety, fiber, hydration, sleep, and lower ultra-processed intake.
5) Why do antibiotics reduce the score?
Antibiotics can disrupt gut communities for weeks. The calculator applies a short-term penalty to reflect recovery time. Focus on steady fiber, plant variety, and overall routine consistency after finishing treatment.
6) How can I improve fastest without drastic dieting?
Add one high-fiber food daily, increase plants by two uniques per day, and replace one ultra-processed snack with fruit, yogurt, nuts, or hummus. These changes often lift multiple subscores at once.
