Featured speaker at LongevityFest 2025 in Las Vegas, the largest longevity conference in the United States with more than 8,000 healthcare professionals in attendance. Topic: Changing the Trajectory of Longevity: Using Continuous Glucose Monitoring as a Personalized Medicine Tool to Extend Healthspan.

  • The Science of Longevity: What Actually Moves the Needle

    Which interventions have outcome data behind them, which are marketing, and how to tell the difference.

  • Metabolic Health as the Foundation of Longevity

    Why fasting insulin, visceral fat, and muscle mass predict healthspan better than weight or BMI.

  • Building Metabolic Resilience for a Longer, Healthier Life

    The measurable markers of resilience and the protocols that move them within 90 days.

  • Muscle, Metabolism and the Aging Process

    Muscle as the organ of longevity, and why losing it is the most preventable cause of decline.

  • The Longevity Blueprint: Evidence-Based Strategies for Healthspan

    A practical order of operations for patients and clinicians, from baseline testing to intervention.

  • Women, Hormones and Longevity

    What perimenopause does to metabolism, body composition, and risk, and what to do about it.

  • GLP-1s, Muscle Preservation and the Future of Metabolic Medicine

    How to use GLP-1 medications without trading fat for muscle, from a surgeon who has seen both outcomes.

  • Biomarkers, Wearables and Personalized Longevity

    Turning CGM, VO2 max, body composition, and blood panels into decisions instead of dashboards.

  • Performance, Recovery and Human Optimization

    Applying longevity medicine to athletes, executives, and anyone who wants to perform at 50 like they did at 35.

  • The Future of Medicine: From Disease Treatment to Healthspan Extension

    Why the next decade of healthcare moves upstream, and what that means for practitioners and patients.

  • The Practitioner as the Patient

    Teaching healthcare providers to put their own health first before burnout decides for them.

Ask Dr. Sweeney

I'm on a GLP-1 and losing weight fast. Why do you keep talking about muscle?

Because if we are sacrificing muscle just to be a smaller pant size, we are shortening our life. Muscle is the organ of longevity. It clears glucose, holds you upright at 80, and predicts how long you live independent of what the scale says. In my practice, GLP-1 patients train with resistance, hit a protein target, and get a body composition scan every visit so we know what they lost. The drug is a tool. The protocol around it decides the outcome.

What is the one test everyone over 40 should get that their doctor probably is not ordering?

Fasting insulin, and right behind it, an omega-3 index. A normal fasting glucose can sit on top of insulin that has been climbing for a decade. By the time glucose moves, you have lost years of runway. Insulin is the #1 biomarker of healthspan, and the longest-living people on Earth have low fasting insulin levels, so you need to know what yours is. On omega-3, nine out of ten patients who walk into my office test below 4 percent. The longevity literature target is above 8. Standard labs call 5 fine. Those two numbers tell me more about where you are headed than your typical annual physical.

You were a surgeon in the conventional healthcare model for two decades. Why leave?

Because I was tired of working in the conventional system that treats patients reactively rather than proactively. Most bariatric surgery patients that I operated on didn't need to be there in the first place. Their disease could have been treated decades before they met me. Bariatric surgery works. I believe in it. But I also believe in a proactive healthcare model. I can identify the precursors to disease long before conventional medicine makes a diagnosis. This gives us plenty of time to make changes and optimize someone's health for the long run. There is a lot of illegitimate noise in the longevity space. I am the legitimate one that cuts through the noise with real science, experience, and outcomes.

Why did a bariatric surgeon move into longevity medicine?

Because, in her words, it is one continuum. Bariatric surgery is metabolic health at its most reactive extreme. Longevity medicine is the same problem at its most proactive. After 14 years treating the end stage, including livers so enlarged from metabolic dysfunction they took two retractors to lift, she wanted to find those patients 20 years earlier. She calls herself a fixer: start at the bottom, fix it there, and everything upstream gets better.
