Will Bulsiewicz on plant diversity, SCFAs, and why keto starves the microbiome
The gastroenterologist’s NYT bestseller: feed gut microbes a wide range of plants so they make short-chain fatty acids. A 28-day jumpstart and a direct argument against elimination diets as a default. Pair with our fiber and probiotic guides; psyllium is the cheap SKU if the book outruns your kitchen.
Typical price: $16 – $28 USD
How It Works
Clinical GI plus microbiome popular science. Strongest on fiber and plant variety. Weaker where every symptom is a missing polyphenol. Not a substitute for IBD care or a colonoscopy you are avoiding.
Diversity Over Restriction
Thirty plants a week beats a three-food ‘heal your gut’ menu. FODMAP and clinical elimination are temporary tools, not identities.
SCFAs
Fiber → microbes → butyrate and friends. That is the mechanism chapter.
Twenty-Eight Days
Menus and recipes. Start with beans and a green if 28 days of recipes is how you quit books.

Community Reviews
Synthesized consensus from Reddit, forums, and expert sources.
Praised as practical; low-carb readers dislike the keto critique. The 30-plants idea is what people keep.
