Food, Fasting and Cancer: The Claims, the Science and the Evidence
Signature Course No. 603 — A Signature AI Socratic Coaching Course.
No experience needed — your coach starts where you are.
A New Kind of Learning
Socratic coaching, delivered by an agentic AI coach.
Not a course you watch. An AI coach you work with.
The Lighthouse Coach begins by discovering how you think about the subject, teaches what is missing, and gives you realistic practice before asking you to prove that you can use it. You may test out of concepts you already understand, while capstones turn the learning into a practical plan, decision, conversation, or other real-world result.
The curriculum is deliberately authored; the AI delivers it through coaching. It is not an AI randomly generating lessons.
A coach that teaches by asking — not by lecturing
The Lighthouse Coach is an AI Socratic coach built on Cognosco Learning's Food, Fasting and Cancer: The Claims, the Science and the Evidence course, in the Personal Effectiveness & Well-Being category. It does not play videos at you. It holds a conversation: it asks you a question, listens to your answer, names the misconception it hears, affirms what you got right, and asks the next question — the way a great coach works in the room.
The claims are everywhere — and they deserve better than a shrug. A video watched by millions says a common food is feeding your cancer. Another says a way of eating can starve cancer where it sits. The people sharing these videos are very often people who love someone with cancer, doing exactly what a person does when the standard road feels too slow: looking for another door. This course takes that search seriously. It states each claim in its strongest honest form — the form its most serious proponents would recognise as their own — and then grades each claim against the published evidence, concept by concept, showing its work.
It starts with the debate on the table. Three claims: food feeds cancer, and some foods feed it more than others; cancer is a metabolic disease, and metabolism can be pressed; and fasting, timed around treatment, can tilt the field. You will learn the machinery underneath them — what the word cancer actually names, the Warburg effect and its modern reassessment, why a tumour's appetite for glucose does not make dietary sugar a lever you control, angiogenesis as real medicine first, and what fasting measurably does to a body.
It works in two movements. First, Module 1 — The Claims and the Machinery — work through Concepts 1–9, finishing with The Claim Audit Brief; then, Module 2 — The Evidence and the Ledger — work through Concepts 10–18, finishing with The Evidence Ledger and the Question Sheet.
Both capstones produce real artifacts — a claim audit brief on a viral cancer claim, written to be read by people who are frightened, built on the running case of Priya Nair, communications lead at Kestrel Freight Lines, briefing her staff by Friday; and a complete evidence ledger on a claim of your choosing, with a one-page question sheet a patient or family member could carry into a real appointment.
The fences are part of the course. This course contains no treatment content — no fasting schedules, no dietary treatment plans, no supplement regimens, nothing a patient could follow as therapy. It appraises claims; it does not make them. Its stance is the course book's own, in two sentences: this course makes no claims. It opens a possibility — the possibility that this research territory is real, active, and worth understanding properly, and that you can hold its whole map: what is known, what is guessed, what is being tested, and what is not known at all.
The course is self-paced and always on — roughly 30 minutes per concept, about 9 hours in full, taken in as many sittings as you like. You can type your answers, or talk out loud: the Voice Coach speaks its questions and listens to your spoken replies. Learners who already know the material can test out concept by concept.
Food, Fasting and Cancer: The Claims, the Science and the Evidence is part of The Lighthouse Signature Series — the online counterpart to the one-day, in-person learning Cognosco Learning delivers.

Diagnose
The Coach starts where the course starts: with the claims already on your table. Which of the three claims have you already encountered — and in what form: a headline, a clip, a conversation with someone frightened? If you had to state the metabolic claim to its own proponent, what would he correct in your version? And which claim do you most want to be true — written down, because that wanting is data about you, not about the evidence. Every concept opens with three questions that locate where you actually stand, and your answers shape how deeply the Coach works the concept with you. Everyone begins with Module 1 — no skipping the foundations you only think you have.
Learn & Practice
Work each concept in conversation with the Coach — spoken or written — then practice it against realistic situations until it holds up.
Prove
Every concept ends in proof: answer the check cold and demonstrate the skill. Know it already? Test out and take credit immediately.
Capstone
Finish with two capstones — The Claim Audit Brief for Module 1 and The Evidence Ledger and the Question Sheet for Module 2 — that pull the whole course together, and earn the certificate.
What You'll Learn
Fairly stated before graded — always. No claim in this course is graded before it has been presented in the strongest form its serious proponents would accept; a verdict you cannot trace back through a fair statement is worth nothing. And every finding is reported with its species, its size, and its endpoint attached, because in this field the distance between a mouse and a person, and between a biomarker and a survival curve, is where all the mischief lives.
Module 1 states the debate fairly and builds the biology underneath it. The Debate on the Table; One Word, Two Hundred Diseases; The Warburg Observation; The Modern Reassessment; The Metabolic Theory at Full Strength; The Mainstream Answer; Sugar, Blood, and the Tumour; Angiogenesis; and What Fasting Actually Does — worked throughout on Kestrel Freight Lines and Priya Nair's Friday brief, whose facts are stipulated for teaching while the science is not.
Module 2 grades everything. Reading a Mouse Like an Adult; The Human Fasting Trials, Part One; The Human Fasting Trials, Part Two; The Ketogenic Evidence; Where the Evidence Is Genuinely Strong; The Other Side of the Ledger; What the Authorities Actually Say; Reading the Next Headline; and The Honest Close — ending with the whole map on one page: what is known, what is open, and what to do on Monday.
And it holds its fences throughout. The research discussed here concerns mostly solid tumours, mostly in animals, with a small number of early human trials, nearly all of it alongside — never instead of — standard therapy. Fasting and restrictive diets during cancer treatment can be dangerous, and every serious trial in this field screened out patients who were underweight or at risk of malnourishment and ran under medical supervision. Where the evidence ends, this course says so, in plain words, at the exact place it ends.

Built for anyone who has felt the pull of these claims
Anyone who has watched one of these videos and felt the pull of it — for themselves, for a parent, for a partner, for a friend — and wants more than a fact-checker's shrug or a believer's certainty.
The colleague asked to brief a team, the family member who sits in the waiting room with a phone full of links, and the curious reader who suspects the truth here is more interesting than either headline.
It assumes no science background. It assumes you can think, and it asks you to. One question it will not answer for you: whether any of this applies to a person you love — that question belongs, with better questions in hand, to their oncology team.

Before you enroll
What is a Socratic coaching session?
A conversation, not a video. Your coach asks a question; you answer — out loud by voice, or by typing — and the coach responds to what you said: naming the misconception it hears, affirming what you got right, and asking the next question. You advance only when you have mastered each concept, so a finished course means the learning held.
How long does it take — and how long do I have?
About 30 minutes per concept. Learn in sittings of any length; your progress is saved as you go. You have a full year from purchase to finish, and you can revisit and retake within that year.
What does the certificate verify?
That you completed every concept and both capstones of this course. Anyone can confirm a Cognosco certificate online — enter its certificate ID on our verification page.
What if it isn't for me — what are the refunds?
If you have not started, cancel for a full refund within seven days of purchase. Once you have started, there is no cash refund — stop before finishing and we credit the full amount you paid toward any other course in the library (credit valid one year from your original purchase). Once you complete the course, no refund or credit applies.
