Marrow: Ancestral Protocol

Marrow reads your morning vitals and tells you exactly where your metabolism stands — what yesterday's eating, sleep, and protocol likely caused it, and what to do today. Animal-first nutrition with peptide and cycle awareness, all on-device. YOUR WAKING TEMPERATURE IS A METABOLIC REPORT CARD The temperature you take before getting out of bed reflects what your body burned overnight. 97.2–97.8°F means fat-burning. Below that: under-fueled or thyroid suppressed. Above 98.6°F: inflammation, glycogen load, or glucose mode. Marrow classifies every reading into one of six metabolic zones and plots a 14-day trend so you can see exactly where your metabolism is heading. DIET CORRELATION — WHAT CAUSED TODAY'S READING The app reads yesterday's meal log and surfaces the most likely driver of today's temperature. Late dinner with starchy food? Expect +0.3–0.5°F. Organ meats and salt water? Expect stable or lower. OMAD? The fast window shows in the morning signal. This is the retrospective feedback loop that animal-first and ketogenic dieters have never had before. ANCESTRAL PROTOCOL, MEASURED Animal foods remain the base — meat, organs, eggs, fatty fish — but Marrow now includes the selective additions that survived honest evidence review: berries, citrus, walnuts, pecans, macadamia, Brazil nuts, sulforaphane, bovine colostrum, raw aged cheese. Honey, grains, legumes, and pasteurized dairy stay excluded. PEPTIDE AWARENESS For users running growth-axis peptides (Tesamorelin, Ipamorelin/CJC, BPC-157, Thymosin Alpha-1, Cerebrolysin), Marrow tracks the biomarkers that matter — IGF-1 with cancer-relevant thresholds, HbA1c, ApoB, hs-CRP, homocysteine. The Fix library knows that high protein plus growth peptides stack IGF-1 elevation, and what to do about it. PERIODIC FASTING PROTOCOLS Five-day water, bone broth, and fat fast cadences with day-by-day expectations. Drops IGF-1 30–50%, triggers autophagy, mandatory off-cycle countermeasure for anyone using growth peptides. 15 BIOMETRIC SIGNAL MOMENTS The app watches your data continuously and surfaces a full-screen signal the moment something meaningful happens — new weight low, fat-adapted state confirmed, waist milestone, silent recomposition, temperature reversal, logging streak. Warning signals too: rapid weight gain, waist creep, temp suppression, energy slump. PROTEIN-FIRST TRACKING Your protein target is calculated from lean body mass using the US Navy body composition method. The protein ring is your primary metric — not calories — because on animal-first eating, protein adequacy drives everything. LONGEVITY SIGNALS - Zone 2 cardio minutes with weekly ring and heart rate targets - Grip strength against Lancet PURE study norms (139,000 subjects, age and sex matched) NUTRIENT DENSITY 26 micronutrients tracked across organ meats, seafood, ruminant cuts, fruit, and nuts. Polyphenols (mg, Phenol-Explorer), histamine load, and macros all included. CYCLE INTEGRATION Morning weight, waist, and basal body temperature flow to Apple Health automatically — Apple Watch, scales, and cycle apps like Forecast read the same numbers. Cycle phase context surfaces in the morning log when paired with a cycle tracker. CRAVING INTERRUPTION + PROTOCOL FIXES Evidence-based swap suggestions for the hard adaptation weeks, plus deeper fixes: IGF-1 elevated, carb reintroduction, heat damage from high-temp cooking, peptide cycling. All data stays on your device. No accounts. No subscriptions. No cloud.
