Everything you need to know about fiber, gut health, and making it all work in real life.
This is where I write about fiber in more detail than an app screen allows. Grove can tell you how many grams you ate. It cannot explain why 25 grams is the number, which foods get you there fastest, or what to do when eating more fiber makes the bloating worse for a week before it gets better. That is what these posts are for.
Most of what you will find here falls into three groups. Reference guides, like how much fiber you need per day and which foods carry the most per serving. Explainers on the things people are actually searching for, like fibermaxxing and the 30 plants per week rule, with the research behind them. And app comparisons, including the ones where Grove is not the right pick.
I am James McKinney. I build Grove, a fiber tracker for iPhone, and I write everything here myself. When a post makes a claim about grams or health outcomes, it points to the USDA data or the study it came from so you can check the source yourself.
These posts are written for anyone who feels the problem before they know the cause. Constipation, bloating, an afternoon energy dip, hunger an hour after lunch. Low fiber is a common thread in all of them, and it gets easier to fix once you can see your own numbers.
