Cutcliffe groups the everyday signs of a disrupted gut-metabolism axis into four observable areas: GI issues, difficulty maintaining weight, food cravings, and fading energy. The method starts with repeated changes from a person's own baseline rather than a single bad day. Those soft signals can be tracked without equipment by recording digestion, food tolerance, stable portion sizes, cravings, post-meal energy, sleep, and workout performance. If a pattern persists, objective measures such as hemoglobin A1C, fasting blood glucose, or glucose spikes can test whether sugar metabolism has changed. The framework is therefore a triage and monitoring tool: notice a multi-signal pattern, document it over time, then use harder endpoints or professional assessment rather than treating subjective symptoms as a diagnosis.
Origin
Colleen Cutcliffe described the four ways a disrupted gut-metabolism axis tends to show up, then distinguished these soft indicators from A1C and blood-glucose measurements.
Core principles
- 01Metabolic changes often appear in daily life before formal testing
- 02One symptom alone is weak evidence; patterns across signals are more useful
- 03Compare changes against your own baseline rather than someone else's
- 04Use blood glucose and A1C when objective confirmation is needed
How to run it
- 1
Set your baseline
Write down what normal digestion, appetite, weight stability, and daily energy look like for you. Use a typical week rather than an unusually good or bad day.
Pro tip Keep food portions and observation times reasonably consistent so changes are easier to interpret.
Watch out Do not treat another person's baseline as your target.
- 2
Check GI signals
Record bloating, pain, gas, and food sensitivities, especially sensitivities that are new. Look for recurrence rather than isolated discomfort.
Watch out Acute or severe symptoms require medical attention, not self-tracking alone.
- 3
Check weight maintenance
Observe whether the same approximate portions and activity now produce a different weight trend. A need to continually eat less just to maintain the same weight is a signal worth documenting.
Pro tip Use a multi-week trend instead of daily scale changes.
- 4
Check cravings and energy
Note changes in food cravings alongside post-lunch slumps, sleep, and workout capacity. These show how appetite signalling and energy may be changing in daily life.
Pro tip Record the timing and context of each change, not just its presence.
- 5
Confirm persistent patterns
When several signals persist, discuss objective measures such as A1C, fasting glucose, or glucose responses with a qualified professional. Use the measurements to test the pattern rather than assuming a cause.
Pro tip Bring the tracking record so the discussion starts with evidence.
Watch out The four signals are nonspecific and can have causes unrelated to the gut microbiome.
In the wild
A person notices that the same lunch now leads to bloating, a sharp afternoon energy drop, and stronger sugar cravings. They log those three signals for three weeks while keeping portions broadly stable. Because the pattern persists across several signals, they take the record to a clinician and ask whether objective glucose testing is appropriate.
→ A vague feeling of slowing metabolism becomes a documented pattern suitable for professional review.
Common mistakes
Diagnosing from one signal
Bloating or one tired afternoon is not enough to identify a metabolic problem. Look for persistent changes and multiple signals.
Confusing tracking with diagnosis
The checklist helps organize observations but cannot establish the cause. Confirm concerning patterns through appropriate clinical assessment.
Is it for you?
Best for
People who want to notice and document changes in digestion, weight maintenance, cravings, and energy.
Not ideal for
It is not a diagnostic substitute for clinical assessment, blood work, or treatment of acute symptoms.
From the transcript
“so this gut metabolism axis when it's gone awry it shows up with GI issues weight cravings and energy”
“the kind of gold standard measurements of metabolism are what is your hemoglobin A1c and what is your you know what are your blood glucose…”
