Levels Health: Continuous Glucose Monitoring and Metabolic Intelligence for Longevity

Metabolic health is the foundation of longevity — and most people have no idea where they stand. Glucose dysregulation, insulin resistance, and metabolic dysfunction are the upstream drivers of cardiovascular disease, type 2 diabetes, cognitive decline, and accelerated aging. They develop silently, over years, before conventional lab tests catch them. Levels was built to close this gap: giving individuals real-time metabolic intelligence, clinician review, and actionable guidance — before dysfunction becomes disease.

What Is Levels Health?

Levels Health is a metabolic health company that makes continuous glucose monitoring (CGM) accessible to healthy, performance-focused individuals — not just diabetics. Founded with the mission to translate real-time biological data into actionable health decisions, Levels has built a platform that combines CGM technology with comprehensive blood lab panels, AI-driven insights, and clinical oversight into a single membership.

The fundamental insight behind Levels is that glucose — your blood sugar — is the most information-dense single biomarker available without invasive measurement. It responds in real time to food, exercise, sleep, stress, and recovery. Tracking it continuously reveals patterns that a single fasting glucose test or even an HbA1c can never capture: which specific foods spike you, how different meals interact, how sleep quality affects next-day glucose stability, and how your metabolic resilience is trending over weeks and months.

The Core Technology: CGM + Labs + AI

Continuous Glucose Monitoring

CGM devices — small sensors worn on the upper arm or abdomen — measure interstitial glucose every few minutes, 24 hours a day, for the duration of the sensor wear period (typically 14 days per sensor). The Levels app integrates this data stream and presents it in context: meal logs, exercise events, sleep periods, and stress markers are overlaid on glucose traces to create a complete metabolic picture.

For a biohacker or longevity enthusiast, CGM provides something that no retrospective test can: the ability to run controlled experiments on your own biology. Eat two different breakfast compositions and directly observe the glucose response. Add a post-meal walk and watch the spike attenuate in real time. Test the metabolic impact of different sleep durations or training modalities on glucose stability the following day.

Comprehensive Lab Testing

CGM alone captures glucose dynamics — but metabolic health is broader. Levels includes lab panels that measure the markers that matter most for long-term health:

• Fasting insulin and HOMA-IR — the most sensitive early indicators of insulin resistance, which CGM alone cannot measure.
• ApoB and LDL-C — cardiovascular risk markers; ApoB in particular is a stronger predictor of atherosclerotic risk than standard LDL.
• Triglycerides — elevated triglycerides are a direct metabolic marker linked to insulin resistance and cardiovascular risk.
• HbA1c — a 90-day average of blood glucose, the standard clinical marker for pre-diabetes and diabetes risk.
• Comprehensive panels (Core and Complete plans) extend to 28+ or 100+ markers including inflammatory, hormonal, thyroid, and kidney function markers.

Critically, Levels provides clinician review of these results — not just a PDF of reference ranges. Members on Core and Complete plans receive physician-guided interpretation of their data, contextualized against their CGM patterns and lifestyle inputs.

AI Health Insights and Adaptive Programs

The Levels app uses AI to synthesize CGM data and lab results into personalized recommendations. The system identifies patterns — which food combinations consistently elevate your glucose, what your peak recovery window looks like, where your biggest metabolic risks lie — and generates specific, prioritized actions. Adaptive programs adjust as your data changes, so the guidance evolves with your metabolic state rather than remaining static.

Why Metabolic Health Is the Core Longevity Lever

The scientific case for metabolic health as a longevity determinant is overwhelming. Insulin resistance — even in its pre-clinical, subclinical form — is a driver or accelerant of virtually every major age-related disease: cardiovascular disease, Alzheimer's disease (increasingly described as "type 3 diabetes"), cancer, non-alcoholic fatty liver disease, and type 2 diabetes itself. It is also a primary driver of accelerated biological aging as measured by epigenetic clocks.

Yet the conventional medical system does not catch insulin resistance early. A fasting glucose test under 100 mg/dL is considered "normal" — but you can have severe insulin resistance with normal fasting glucose. The first sign most people receive of metabolic dysfunction is a disease diagnosis, not a preventive warning.

Levels addresses this gap directly. By combining real-time glucose data with fasting insulin measurement, comprehensive lipid panels, and clinician review, it gives individuals the tools to identify and act on metabolic dysfunction years before it becomes clinical — which is when lifestyle interventions are most powerful and medication is least necessary.

Member Outcomes

With over 100,000 members, Levels has generated a substantial real-world evidence base for its approach:

• 80% of members improve out-of-range biomarkers on their program.
• 79% lowered fasting insulin — reducing early risk for metabolic disease and type 2 diabetes.
• 81% improved HbA1c, with many reversing prediabetes status.
• 84% reduced triglycerides, most by 30 mg/dL or more.

These are not marginal improvements — they represent meaningful metabolic shifts that directly translate to reduced long-term disease risk.

The Scientific Advisory Board

Levels has assembled one of the strongest metabolic health advisory boards in the consumer health space:

• David Perlmutter MD, FACN — Five-time NYT bestselling author (Drop Acid, Brain Wash, Grain Brain), leading voice on metabolic drivers of neurological disease.
• Ben Bikman PhD — Author of Why We Get Sick, scientist and professor specializing in insulin resistance; Board member of the American Diabetes Society.
• Rob Lustig MD, MSL — Professor Emeritus of Pediatrics, Division of Endocrinology; leading researcher on fructose metabolism and metabolic disease.
• Sara Gottfried MD — Author and physician-scientist specializing in hormonal and metabolic health in women.
• Dom D''Agostino PhD — Research scientist and professor, leading authority on ketogenic metabolism and metabolic oncology.
• Terry Wahls MD — Author of The Wahls Protocol, clinical professor and researcher on metabolic interventions for autoimmune disease.

This advisory board is not decorative — these researchers actively inform Levels' approach to biomarker selection, protocol design, and content.
