Insulin resistance isn’t just about sugar—and it’s not just about weight.

In this episode of Health Hacks, Tara Peterson and Dr. Jeni explain why resistance training is one of the most effective tools for improving insulin sensitivity and protecting metabolic health.

Using current research and clinical insight, they break down how insulin works, why muscle is the body’s largest glucose sink, and how strength training improves blood sugar control, reduces visceral fat, lowers inflammation, and slows metabolic aging—even after the workout is over.

You’ll also learn why up to 93% of U.S. adults are metabolically unhealthy, why muscle loss accelerates insulin resistance after age 30, and how just 2–3 strength training sessions per week can make a meaningful difference.

If you’re struggling with blood sugar swings, fatigue, inflammation, or stubborn weight gain—this episode is for you.

In This Episode, We Cover:

• What insulin does and how insulin resistance develops

• Why insulin resistance can exist even at a normal weight

• NHANES data showing 93% of U.S. adults are metabolically unhealthy

• The role of skeletal muscle as the body’s largest glucose sink

• How excess blood sugar is stored as fat—especially visceral fat

• Why visceral fat worsens inflammation and insulin resistance

• How resistance training improves insulin sensitivity for 24–48 hours post-workout

• The connection between muscle mass, mitochondria, and metabolic aging

• Why adults lose 3–8% of muscle mass per decade after age 30

• How strength training protects against metabolic decline and chronic disease

• Practical guidance on how often to strength train for metabolic health

Resistance training isn’t just about strength—it’s about blood sugar control, inflammation reduction, hormone balance, and long-term metabolic resilience.

• NHANES Metabolic Health Data
  Estimates indicate that ~93% of U.S. adults meet criteria for poor metabolic health, defined by abnormalities in blood glucose, triglycerides, blood pressure, HDL cholesterol, or waist circumference.
