The Science

GI planning fails when too many variables change at once.

Start with stable defaults, then adjust slowly. The gut microbiome basics page explains why your bacteria respond better to gradual dietary shifts than abrupt ones.

Baseline Method

  1. Two repeat meals built on the 1-1-1 plate formula : a protein anchor, a fiber-rich carb, and produce.
  2. One planned snack option.
  3. One new food test at a time.

When choosing fiber sources, keep in mind that different fiber types behave differently in the gut. Soluble fiber from oats tends to be better tolerated than large doses of insoluble fiber from raw vegetables.

Bottom Line

Controlled variation improves signal and reduces guesswork.

Educational content only. Not medical advice.
