Fixing gut dysbiosis means matching your food choices to what your gut can actually handle right now, not what's generically recommended. As Kieran puts it: "If you follow me I want you to know you are probably eating TOO MUCH fiber". This is especially true for those with active bacterial overgrowths.

## Key takeaways

- What matters is whats good for YOU right now, which often means forgoing fibre for the minute.
- For those with active bacterial overgrowths eating more fiber because someone says "it good" is the equivalent of a man having higher estrogen because "it good".
- But never EVER feed yourself something that makes you feel worse because someone says "it good".

## Why Is Too Much Fibre a Problem for Gut Dysbiosis?

Useful tools for maintaining diversity include:

Exactly the point I'm trying to make, you should focus on foods that are good for you not just fiber as a group.

## How Does Your Microbiome Affect Motility When Adjusting Fibre?

Depending on your microbiome yes, if you're starting from diarrhea it usually has some adjustment period of slower stools also as your body can begin to rely on exernal stimuli for motility. This ties into the broader picture of [gut motility](https://gutfix.ai/blog/how-can-i-improve-my-gut-motility) and how it responds to dietary changes. Not saying all is bad, just depends on what you tolerate.
