Body Signals, Checked
The vagus nerve, cortisol, glucose spikes and “chronic inflammation” — what the science actually says. Four books in one.
Your feed says your vagus nerve needs resetting, your cortisol is broken, your glucose spikes are ageing you and everything you eat is inflammatory. Four complete books check whether any of that survives contact with the evidence — full text, nothing abridged, every claim blind-checked before publication.
A collection, not a new book: this is the complete, unabridged text of 4 titles that are also sold separately. If you already own some of them, buy the ones you're missing instead — they're all here.
What's inside
Every book below in full. Each one keeps its own verification ledger — the collection doesn't have one of its own, because the claims are the books' claims.
The Vagus Nerve, Decoded
What the science actually says about your body's most misunderstood nerve.
The Cortisol Myth
What stress hormones actually do, and what the internet gets wrong.
Glucose Spike Check
What your CGM graph actually means, if you don't have diabetes.
Not Another Anti-Inflammatory Diet Book
Honestly checking “chronic inflammation”, inflammaging, and the foods-cause-inflammation panic — no supplements to sell.
Across the collection
- What the vagus nerve actually is, and whether the “vagal tone” hacks do what the internet claims
- What cortisol actually does — and who profits from the “adrenal fatigue” story
- How to read a CGM graph if you don't have diabetes, and when it's a see-your-GP problem instead
- What “chronic inflammation” really means, versus how the word is used to sell things
- Each book's full verification ledger, published — including the claims that failed
- No supplements to sell, no protocol to buy — just the scorecards
The honest part
A machine wrote these books. We say so on the first page of each one: the dishonest move was never using the machine — it's hiding it, and never checking whether a word of it was true. So a practising doctor read every page and threw out what didn't hold up. Here's exactly how they're made, and the corrections page where we fix what we get wrong, in the open.
The receipts are per book, not per bundle: 2 of the 4 titles here publishes its full verification ledger, including the claims that didn't survive first contact with their own sources. The links are in the list above.
