One protocol, taken seriously.

What we are

The Sardine Protocol is the science-grounded system for using short sardine fasts to restore metabolic flexibility, drop visceral fat, and clear inflammation — without losing muscle or joining a cult.

That’s the positioning, in one sentence. The rest of this page is what it commits us to.

One thing, best in the world

We are the cornerstone protocol — sardine fasting, done right, with the science behind it. We are not a general biohacking brand, not a fasting-of-the-month shop, not a longevity-stack newsletter. Adjacent practices (cold exposure, breath work, sleep, training, supplementation) appear only as contextual modifiers inside higher tiers — never as primary brand surface. If we widen the topic, we lose the moat. The moat is the focus.

Free vs paid

Free = what the science says. Paid = how to apply it (and what we’ve learned applying it).

The public layer of the research library — every source, every summary, every mechanism page, one full founder cycle log — is broad and deep on purpose. That’s the SEO surface that compounds into topical authority and the public evidence that the moat exists. The paid layer is the applied translation: dossiers, biomarker review sessions, the founder N=1 dataset across years, member case studies, expert AMAs.

What we never claim

This list is non-negotiable. Violations damage the brand and create real liability.

• No cancer cure or treatment claims. Historical context is not a claim.
• No diabetes reversal claims. “Improved glucose markers” is OK with citations. “Reverses diabetes” is a regulated medical claim.
• No weight-loss guarantees. Reference biomarker outcomes from cited studies; never promise specific results.
• No mental-health treatment positioning. Refer to qualified providers.
• No detox or cleansing language. Pseudoscientific. Never.
• No “replace your medication” advice. Always defer to the clinician who knows your case.
• No personalized supplement protocols. General education is fine; individualized recommendations are out of scope.

Voice

• Cite primary sources. PubMed beats podcast beats influencer.
• Show the data. The founder’s biomarkers across cycles. Member case studies, with consent and anonymized.
• No tribalism. We don’t bash keto, carnivore, plant-based, or other fasting variants. The audience overlaps; we’re additive.
• Acknowledge what we don’t know. Thin evidence gets called thin.
