Episode notes
Detox Cleanses Misplace The Real Reset
- Detox culture misunderstands physiology; liver and kidneys handle toxins far better than commercial cleanses.
- Cleanses often remove fiber, depriving the colon of the material that helps 'reset' the microbiome.
Ramp Up Fiber Slowly To Avoid Gas
- Increase fiber gradually to avoid bloating, gas, and discomfort.
- Microbiome shifts take ~8–10 weeks, so ramp intake slowly and consider small psyllium doses (3–5g) rather than a sudden jump.
Go When Your Body Signals Not For Once‑a‑Day Ideals
- Respond to natural bowel urges rather than delaying to chase a 'once‑a‑day' ideal.
- Waiting dries stool as the colon pulls water, increasing strain; go when your colon signals for an easier, quicker evacuation.
