Insulin Resistance Prevalence

The metabolic dysfunction affecting half the adult population — and its direct link to hormonal decline.

U.S. Adults with Insulin Resistance48.8%

NHANES 2017–2020 · n=8,614 adults ≥20

Adults with Prediabetes (HbA1c 5.7–6.4%)38.0%

CDC 2022 · 97.6 million adults ≥18

Men with Low T Who Have Insulin Resistance52.4%

Dhindsa et al., 2010 · Cross-sectional study

Hypogonadal Men with Metabolic Syndrome45.0%

Corona et al., JCEM 2017 · Meta-analysis, n=24,000+

Men with Metabolic Syndrome Showing Low T35.0%

How Insulin Resistance Crushes Testosterone

Insulin resistance attacks testosterone through four independent pathways — each measurable in bloodwork.

LH Suppression via Hypothalamic Disruption

SHBG Reduction in Hyperinsulinemia

Direct Testicular Steroidogenesis Impairment

Aromatase Upregulation in Visceral Fat

Lower Testosterone in IR vs. Non-IR Men~30%

Pitteloud et al., JCEM 2005 · n=60 men, clamp-verified IR

Metabolic Markers & Hormonal Thresholds

The specific numbers where metabolic dysfunction begins to erode hormonal health.

200 cm²

Visceral Fat Threshold

Above this, T drops measurably

10–12 μIU/mL

Fasting Insulin Optimal Range

Above 12 = insulin resistance likely

2.0 ratio

Triglyceride:HDL Ratio

Above 2.0 = significant IR risk

30–50 nmol/L

Optimal SHBG Range

Below 30 suggests hyperinsulinemia

5.0 %

HbA1c Threshold

Above 5.0% = declining glucose control

15 %

Body Fat Sweet Spot

Below 15%, aromatase activity drops
