Key wellness & productivity takeaways (insulin resistance focus)

1) Recognize insulin resistance before glucose rises

  • Fasting glucose often stays normal for a long time because the body compensates by producing extra insulin.
  • Insulin becomes the “main indicator” earlier than glucose; glucose is described as the last marker to change.

2) Use earlier biomarkers/tests than standard glucose alone

Consider pairing or calculating the following:

  • Fasting insulin + fasting glucose, plus HOMA-IR (HOMA)
    • Higher fasting insulin with still-normal glucose suggests insulin resistance / hyperinsulinemia.
  • Triglyceride–glucose index (TyG)
    • Elevated values indicate higher risk of metabolic dysregulation.
  • Triglyceride / HDL ratio (from a standard lipid profile)
    • Goal: ideally < 1
    • Higher ratios suggest increased cardiovascular risk.
  • Waist-to-height ratio (waist circumference ÷ height)
    • Presented as a better metabolic-risk indicator than BMI because it relates to abdominal (organ-area) fat distribution.

3) Watch for physical/clinical “outward signals” that cluster together

The episode highlights skin/body indicators such as:

  • Acanthosis nigricans Dark skin discoloration on areas like the neck, armpits, or groin.

  • Skin tags / skin protrusions (“stilettos”) Often found alongside acanthosis nigricans.

  • Central fat distribution Beer belly, muffin top, love handles.

Cognitive/energy/metabolic symptoms mentioned include:

  • Energy dips
  • Brain fog / concentration issues
  • Carb/sugar cravings shortly after eating
  • Difficulty losing weight despite following a proven method

Rule of thumb from the episode: these signs aren’t decisive alone, but the presence of 2+ together is a strong reason to suspect insulin resistance.

4) Don’t assume “no carbs” = “no insulin resistance”

  • Even with low carbohydrate intake, insulin resistance / hyperinsulinemia can still occur.
  • One suggested driver: prolonged stress and unprocessed emotional trauma (linked to earlier episodes/articles).

5) Focus on insulin “recovery time”

  • Typical pattern: after a carbohydrate-rich meal, insulin rises, then returns to baseline within ~1–2 hours.
  • Concerning pattern: insulin remains elevated between meals—an ongoing measurable trend.

6) How health professionals should assess and act (workflow)

  • Assessment / intake steps
    • Ask about insulin resistance as standard practice, even without obvious symptoms.
    • Don’t rely on fasting glucose alone; use tools such as:
      • TyG index
      • Waist-to-height ratio
    • Prefer the insulin response test (insulin measured over time via a curve).
    • Take “silent” physical signals seriously (skin changes, brain fog, etc.).
    • Combine labs with the client’s story:
      • eating patterns, family history, sleep, exercise, stress, and medical history.
  • Intervention approach
    • Start with lifestyle + nutrition before medication.
    • Reassess afterward using the same markers (not just glucose again).

7) Practical self/clinic resources promoted

  • Free insulin resistance check questionnaire (10 questions) for an initial impression.
  • A longer version available after the initial check, with results delivered by email.
  • A training pathway for clinicians/practitioners (see presenters below).

8) Training/course emphasis: “Insulin response test training”

Goal: help professionals measure and interpret insulin resistance across different scenarios (e.g., persistent excess weight, metabolic syndrome risk, and PCOS/PMOS links).

  • Structure
    • 3 half-day sessions over 4 weeks (max 10 participants)
    • Online theory (~4 hours) with expert Peter Vosol
    • In-person practical session (perform the test; bring a test subject)
    • Online interpretation round (placing the curve in clinical context)
  • Mentoring/support
    • Access to equipment (Easy Reader) and test materials
    • 12 months online community/platform access
    • Certificate + follow-up session with an expert mentor
  • Time-saving device capability (beyond insulin)
    • Easy Reader can read values in ~15 minutes for tests such as Vitamin D, hs-CRP, TSH, cortisol, enabling faster in-consultation decisions.
