The science behind Gut Types, microbiome biology, and personalized nutrition — written for people who want to understand their body, not just follow instructions.
The landmark Weizmann Institute study that proved individual glycemic response varies wildly — and why your gut microbiome is the missing variable that explains everything.

A landmark 800-person study showed that identical meals can cause opposite blood sugar responses in different people. The dominant variable wasn't genetics or willpower. It was the gut microbiome.

Ketogenic diets produce extraordinary results in people whose microbiomes are dominated by fat-metabolizing species. In others, the same diet accelerates inflammation, stalls weight loss, and makes people feel worse. The difference has nothing to do with compliance.

The gut-brain connection is no longer fringe science. Specific bacterial species synthesize serotonin, GABA, and dopamine — and your Gut Type determines how much of each you produce. Mood, energy, and mental clarity are gut health problems as much as brain problems.

Chronic low-grade inflammation originating in the gut is now implicated in heart disease, type 2 diabetes, Alzheimer's, and autoimmune conditions. Most people have no idea it's happening. Your Gut Type determines your baseline inflammatory risk — and what to do about it.

Most microbiome tests use 16S rRNA sequencing — a DNA method that identifies which species are present. Viome's RNA metatranscriptomics reveals what those species are actually doing right now. The clinical difference between a census and a live activity report is enormous.

Type D Adaptors have microbiomes that are unusually sensitive to stress, travel, sleep disruption, and irregular eating. Their gut symptoms during difficult periods are not psychosomatic — they are measurable microbial shifts happening within 48 hours of a stressor.

Fiber is universally praised as healthy — but for certain Gut Types, high-fiber diets produce painful fermentation byproducts, bloating, and worsened gut permeability. Understanding why this happens changes how you think about "eating well."
Read Article →The quiz identifies your type based on real symptoms and dietary patterns. Takes 3 minutes. Completely free.
Your gut bacteria regulate melatonin precursors and circadian rhythm signaling. Late eating disrupts these microbial rhythms — but the severity, and the fix, depends almost entirely on your Gut Type.

Viome's Full Body Intelligence Test generates over 50 health scores across gut, oral, and cellular health. Here is what each category means, what optimal looks like, and how these numbers translate into decisions you can actually act on.
