Key Wellness Strategies, Self-Care, and Productivity/Process Tips

Fasting “Protocol” Structure (3 Phases)

  1. Phase 1: Glycogen Depletion
    • Goal: Lower glucose + insulin by exhausting stored glycogen so insulin can normalize.
  2. Phase 2: Metabolic Transition
    • Goal: Shift metabolism toward fat burning / ketone production while managing energy demand.
  3. Phase 3: Refeed
    • Goal: Reintroduce food strategically to support recovery without derailing ketosis.

Duration + Frequency (What to Actually Do)

  • Use a biologically strategic fast, not merely “time not eating.”
  • Core protocol example (“Accelerator Protocol”):
    • 32–36 hours, once per week
    • Up to ~6 weeks
  • Aim to recreate the effect of a 7-day fast using shorter fasting windows:
    • Literature-based target: peak ketones ~4 mmol/L over ~5–7 days
    • Practice target mentioned: reaching ~4–4.5 mmol/L within ~16 hours (for clients following the full setup)

Foundation First (Safety + Effectiveness Criteria)

  • Don’t rely on fasting alone.
    • Results depend on prepping the body and meeting baseline health markers.
  • The speaker frames fasting as having liability, especially regarding muscle loss during prolonged fasting.
  • Suggested readiness markers (as stated):
    • Fasting insulin < 10
    • Visceral fat index < 10
    • Additional markers related to fatty liver risk (non-alcoholic fatty liver disease context)

Core idea: prepare appropriately so the process is effective and safer.

Biomarker-Driven Tracking (Stop Guessing)

  • Ketones are the key metric to follow and are used to guide decisions.
  • Recommended ketone measurement:
    • Serum/interstitial methods (not urine dipsticks)
  • Example devices/systems mentioned:
    • Keto Mojo (finger stick)
    • CKM continuous ketone monitoring patch
  • Principle: “Data drives decisions.”

Pre-Fast Day Strategy (Lock in Glycogen Offloading)

  • Glycogen depletion workout is the anchor of the entire setup.
  • Training emphasis:
    • Earlier training on the pre-fast day is better
    • Resistance training is important for muscle preservation/building during fasting
    • Suggested format:
      • Max intensity / max load resistance training
      • Follow with cardio-metabolic work (cardio alone may not reduce glycogen enough)
    • Resistance example mentioned: goblet squats
  • Reasoning:
    • Resistance + high effort helps drive glycogen depletion quickly.
    • If you’re not training and not activating muscle, the protocol becomes harder to execute well.

Nutrition “Rules” That Prevent Failure

  • Avoid adding extra restriction outside the fast window
    • This helps prevent performance collapse and “brain/gym failure” signals.
  • The non-fasting window matters:
    • Poor nutrition can lead to:
      • worse performance
      • “junk brain”
      • gym becoming “trash”
  • Carb strategy mentioned:
    • Protein + fat primarily around key days
    • Carbohydrates used with purpose:
      • “two times before training and after training” during the protocol
    • Example carb ceilings stated:
      • ~75–100g carbs max on non-training days (described as individualized)

Exercise + Movement During Fasting (Don’t Be Sedentary)

  • Biggest “do not”:
    • Don’t lie on the couch while fasting.
  • Fasting day targets:
    • “20,000+ steps” (intentional movement)
    • Use movement after the last meal and structure it around meals to support improved glycemic variability
  • Sauna + movement as an “energy demand” workhorse:
    • Goal: create low-grade energy demand so the body favors lipolysis

Sauna / Heat Therapy (Self-Care and Metabolic Tool)

  • High-heat sauna is treated as a central tool.
  • Thermal tolerance build-up:
    • Start lower (e.g., 15 minutes) then build up
  • Mentioned ideal ranges:
    • ~3 × 30 minutes, or 2 × 45 minutes (observed approach)
  • If no sauna:
    • Hot water immersion / hot bath ~ 20 minutes can substitute
  • Electrolytes:
    • Electrolytes are intentionally consumed during the fast due to sauna-related electrolyte risk
    • Particularly framed as important for sodium replacement

Caffeine / Non-Nutritive Energy Strategies

  • Coffee is encouraged during the fast.
  • Optional:
    • Zero-calorie / zero-sugar energy drinks
    • Stated as unlikely to meaningfully interfere (based on serial ketone measurements)
  • Messaging:
    • A slight insulin response may occur, but it’s described as insignificant

What to Consume (and Avoid) During the Fast

  • During the fast:
    • No eating (fasting and eating don’t happen together)
    • Only non-nutritive options (e.g., caffeine/coffee; optional non-nutritive energy drinks)
  • Avoid certain supplements that may blunt ketosis:
    • Amino acids / BCAAs may shut down ketosis
      • Example mechanism mentioned: leucine → insulin response
    • Bone broth described as not allowed during the fasting window (“No, you can’t have bone broth.”)

Refeed Protocol (How to Break the Fast)

  • Refeed timing and sequence:
    • Bone broth first
    • Wait at least 2 hours after initial bone broth before eating whole foods
  • Whole-food order after broth:
    • Protein first, then fat, then carbs
    • Carbs are adjusted based on protocol structure
  • Steak example used to discourage abrupt refeed:
    • Breaking fast with a ribeye is described as harsh for gut motility/lining.

Training Schedule Around Fasting (Avoid Underfueling)

  • Discouraged:
    • High-intensity training on fasting day and post-fast day
  • Allowed (with limits):
    • Light lifting / tension around ~50% effort
  • Best timing for intensity:
    • Prioritize the next intense session on the “post-postfast” day
  • Key warning:
    • Training undere-fueled during fasting/post-fast = injury risk and “no top-end fuel.”

“Feeling vs Facts” Mindset (Self-Regulation)

  • The protocol warns against trusting only how someone feels.
  • Approach:
    • Align feelings with measured ketone data
  • Example decision rule:
    • If you wake feeling “locked in,” you may do sauna + movement
    • If you feel “gassed,” refeed immediately
  • Midday stop criteria (as stated):
    • Target serum ketones ≥ 1.5 mmol/L
    • If not achieved, abort/reset rather than “push through.”

Women + Fasting Considerations (As Framed in the Talk)

  • Claim made: women are “biologically optimized to fast,” with:
    • better lipolysis/ketosis responsiveness
  • Main caution:
    • energy restriction outside the designed fast is not advised—restriction should be the fasting itself

Optional Medical Augmentation Mentioned (Doctor-Led)

  • GLP-1 / GLP-related meds discussed as an augmentation tool for some patients:
    • Examples: Mounjaro / Zepbound
  • Timing mentioned:
    • often before the prefast morning
  • Mentioned purpose:
    • improved insulin sensitivity
    • reduced food noise
    • support mitochondrial performance (AMPK-related rationale)
