    0h — 4h Digesting
    Phase 1: Postprandial Digestion & Fuel Storage
    🩸 Blood & Metabolism

    Insulin rises to clear glucose. Excess energy fills liver and muscle glycogen reserves. Lipolysis is paused.

    🦠 Gut & Motility

    Upper GI digestion and nutrient absorption. The Migrating Motor Complex (MMC) is dormant while food is broken down.

    4h — 12h MMC Active
    Phase 2: Postabsorptive State & Housekeeping Sweeps
    🩸 Blood & Metabolism

    Insulin returns to baseline; glucagon rises. Hepatic glycogen maintains steady blood sugar (~80–90 mg/dL).

    🦠 Gut & Motility

    Small intestine clears. MMC Phase III contractions sweep every 90–120m to prevent microbial overgrowth (SIBO).

    12h — 18h Ketosis / Mucin
    Phase 3: The Metabolic Switch & Mucin Renewal
    🩸 Blood & Metabolism

    Liver glycogen depletes; lipolysis accelerates. Serum ketones ($\beta$-hydroxybutyrate) begin rising above 0.3–0.5 mmol/L.

    🦠 Gut & Motility

    Luminal fiber clears. Specialized taxa like Akkermansia forage mucin glycans, signaling goblet cells to thicken the gut lining.

    18h — 24h+ Autophagy
    Phase 4: Deep Autophagy & Quenched Inflammation
    🩸 Blood & Metabolism

    Deep ketosis. Gluconeogenesis stabilizes blood glucose. Intracellular recycling pathways (AMPK activation) peak.

    🦠 Gut & Motility

    Intestinal stem cell renewal. Decreased lipid absorption lowers circulating endotoxins (LPS), calming systemic baseline inflammation.

    🥑 Re-feeding & Gentle Inoculation Gut Priming

    Bile and digestive enzymes downregulate during extended rest. Reintroduce nourishment without osmotic shock or sharp glycemic spikes:

    🥣 Bone Broth / Miso

    Provides electrolytes (Na/K) and glycine to soothe the mucosal barrier 15–20 minutes before solid foods.

    🥑 Avocado & Olive Oil

    Monounsaturated fats and soluble fiber blunt glucose spikes and nourish colon bacteria gently.

    🍳 Soft Eggs / Salmon

    Easily digested complete proteins and choline that don't demand heavy hydrochloric acid surges.

    🫙 Fermented Veggies

    A tablespoon of sauerkraut or kimchi re-inoculates the cleared gut lumen with beneficial lactic acid bacteria.
