Sample analysis

Does coffee after breakfast reduce urgent Type 6 mornings?

In this founder sample, moving coffee until after breakfast cut urgent Type 6 mornings from 4 of 7 to 0 of 7. It suggests coffee timing may have mattered, but it is still one cautious 14-day example.

What this page is

A founder sample. The counts come from one internal test week so you can judge the report format without mistaking it for customer proof or a medical claim.

Baseline week

4 of 7 mornings were Type 6

Experiment week

0 of 7 mornings were Type 6

Urgent mornings

5 of 7 down to 2 of 7

What this page is

In this founder sample, moving coffee until after breakfast cut urgent Type 6 mornings from 4 of 7 to 0 of 7.

It suggests coffee timing may have mattered, but this is still one founder sample, not a customer testimonial and not medical proof.

I wanted one honest example on the site that shows what StoolSense is trying to make easier: compare one week to the next, change one thing, and keep the language cautious.

Starting point

The recurring pattern was simple:

  • coffee within 15 minutes of waking
  • bathroom urgency soon after
  • several mornings drifting toward Bristol Type 6

This was not every day. That is exactly why it was annoying. It felt random enough to be easy to dismiss and frequent enough to keep coming back.

The 14-day setup

Baseline week

  • Coffee before breakfast on 5 of 7 days
  • Type 6 stool on 4 of 7 mornings
  • Urgent bathroom run on 5 of 7 mornings

Experiment week

  • Coffee moved until after breakfast for 7 days
  • No new supplements
  • No fiber changes
  • No deliberate diet reset

What changed

MetricBaseline weekExperiment week
Type 6 mornings4 of 70 of 7
Urgent mornings5 of 72 of 7
Coffee before food5 of 70 of 7

The two urgent mornings during the experiment week both had obvious confounders:

  • one short-sleep night
  • one unusually large weekend breakfast with fast coffee right after

That does not prove coffee timing was the whole answer. It does make the next question clearer.

What did not change

  • Stool timing was still mostly in the first half of the morning
  • The experiment did not remove all urgency
  • One good week is still one good week

That last point matters. This is the kind of pattern worth re-testing, not declaring solved forever.

Why this counts as proof on StoolSense

Because it is specific.

It shows counts. It shows the caveats. It labels the source honestly. It does not pretend one founder week means the same thing will happen for you.

The useful next step

If your own mornings feel random in the same way, copy the structure before you copy the conclusion:

  1. Track one baseline week.
  2. Change one variable.
  3. Compare counts, not vibes.

That is the habit StoolSense is built around.
