Are You Aging Faster Than You Think? How to Test Your Biological Age

Ever met someone who seems years younger than their actual age—or someone whose appearance and health tell a different story? This difference isn’t luck—it’s biological age, a metric that reveals how quickly your body is truly aging on a cellular level.

Good news: Unlike your chronological age (calendar age), biological age is flexible. You have the power to measure it and even reverse it.

Let’s explore what biological age really is, how to measure yours, and the proven ways to lower it for healthier, more vibrant years ahead.

Quick Take:
🟠 Cost: Moderate (varies by testing method)
🟢 Actionable: Highly actionable through lifestyle changes
🟢 Impact: Very high for longevity and disease prevention

The Idea: Biological Age vs. Chronological Age

Your chronological age—the number of birthdays you've had—doesn’t fully represent your health or longevity potential. Biological age measures your body's internal aging process through cellular, genetic, and metabolic markers, offering a far clearer picture of your true health status.

Think of biological age as your internal "speedometer" of aging. If it's higher than your calendar age, your body is aging faster—leaving you vulnerable to disease and decline. Conversely, if your biological age is lower, you're biologically younger, healthier, and likely to live longer.

The Evidence

📚 Scientific Insights:

• A 2018 study published in Molecular Cell demonstrated that biological age (measured by DNA methylation clocks) was a stronger predictor of lifespan and disease risk than chronological age alone.

• A groundbreaking 2023 study published in the journal Aging found that targeted lifestyle interventions—including dietary improvements, regular exercise, quality sleep, and stress management—resulted in a statistically significant reduction in biological age. Remarkably, participants lowered their biological age by an average of 4.6 years in just eight weeks

• Epigenetic age tests (like those from TruDiagnostic, Elysium’s Index, GlycanAge, or InsideTracker) measure biological age accurately, helping guide meaningful lifestyle adjustments.

The Action: How to Measure & Reverse Your Biological Age

Ready to take control of your aging process? Here's exactly how to do it:

1. Measure Your Biological Age (Actionable Tests):

• Epigenetic (DNA methylation) tests: TruDiagnostic, Elysium’s Index, GlycanAge

• Blood-based biomarker panels: InsideTracker or your doctor’s metabolic panel

• These tests provide accurate biological age estimates, highlighting strengths and key areas for improvement.

2. Target Lifestyle Improvements (Proven Effective):

• Diet: Prioritize whole foods, healthy fats, lean proteins, and colorful vegetables. Limit processed foods, refined carbs, and sugars.

• Exercise: Engage in regular cardio (150 min/week) plus strength training (2–3x weekly) to significantly slow biological aging.

• Sleep Quality: Prioritize 7–9 hours of quality sleep per night; sleep is a powerful anti-aging medicine.

• Stress Management: Incorporate stress-reducing practices (meditation, yoga, breathing techniques) regularly.

3. Consider Advanced Supplements:

• Supplements like NMN (which you learned about yesterday), resveratrol, vitamin D, omega-3 fatty acids, and antioxidants can help further support cellular health and biological age reversal.

What’s Next?

Don't just celebrate your birthdays—celebrate lower biological age milestones!

Measure your biological age today to clearly identify opportunities to slow or even reverse the aging process.

Commit to one key change—whether diet, exercise, sleep, or stress—and watch your biological age drop over time.

Start reversing your age today—because healthy longevity is truly within your control.

To your healthiest future,
