He’s the author of “Outlive: The Science and Art of Longevity,” which details evidence-based strategies for health optimization. His work centers on personalized medicine, rigorous self-experimentation, and translating complex science into actionable advice.

Understanding Function Health

Function Health centers on proactive, data-driven wellness and targets prevention before symptoms emerge. Peter Attia’s methodology combines precise diagnostics, holistic lifestyle changes, and continuous monitoring to help you optimize long-term vitality.

Core Principles of Function Health

• Root Cause Identification: Function Health investigates underlying drivers of aging and disease, not isolated symptoms. For example, detailed biomarker analysis helps identify metabolic dysfunction before diabetes develops.
• Personalized Data Use: Function Health emphasizes individualized care through advanced labs, genomics, and biometrics. Individual blood panels, genetic risks, and lifestyle profiles guide your health strategy.
• Prevention and Early Detection: Function Health prioritizes early risk assessment using longitudinal tracking. You begin interventions years before conventional thresholds mark disease.
• Holistic Integration: Function Health treats physical, mental, and emotional well-being as interconnected. Daily movement, strength training routines, nutrition, sleep, and stress management all reinforce your resilience.
• Continuous Optimization: Function Health adapts recommendations based on ongoing results, not static assessments. Future check-ins and data updates drive dynamic, tailored adjustments.

Differences from Traditional Healthcare

• Focus: Function Health emphasizes longevity and optimal function, while traditional healthcare generally concentrates on acute interventions or late-stage disease management.
• Approach: Function Health personalizes prevention through regular, comprehensive analyses, but traditional medicine usually standardizes screenings and applies generalized protocols.
• Engagement: Function Health involves you as an active participant in your own care plan, as opposed to traditional healthcare where clinicians often make decisions with limited patient input.
• Diagnostics: Function Health leverages advanced technologies such as full-spectrum blood panels and genetic markers, while traditional systems typically use fewer, threshold-based lab tests.
• Application: Function Health adapts interventions in real-time, using cumulative personal data, whereas traditional healthcare primarily revises plans only after new issues emerge.

Peter Attia’s Approach to Function Health

Peter Attia’s function health model puts proactive wellness and longevity at the center of your personal health strategy. He integrates high-frequency data review, early intervention, and personalized habit-building to target better outcomes.

Focus on Longevity and Performance

Peter Attia’s approach to longevity and performance uses detailed biomarker analysis paired with habit recommendations. You’ll see him emphasize daily steady-state exercise, zone 2 cardiovascular training, sleep consistency, and nutrition systems built for metabolic health. In clinical practice, patients receive tailored protocols for strength training, aerobic fitness, and stress resilience based on continuous biomarker feedback and individual risk profiles. Notable examples include tracking metrics like VO₂ max, fasting glucose, and lipid subfractions, along with structured movement routines to maintain muscle mass as you age.

Preventive Strategies and Diagnostics

Function Health focuses on preventive strategies and advanced diagnostics by prioritizing root cause identification. Attia deploys blood-based biomarker panels, genomics, and full metabolic workups to catch risks long before symptoms emerge. Patients engage with real-time test tracking, capturing biomarker changes every few months and updating actions accordingly. Interventions start early—such as adjusting nutrition for high-sensitivity CRP elevation or sleep modifications when cortisol patterns shift. Attia’s framework ensures ongoing, adaptive care by cross-referencing diagnostics with lifestyle, resting metabolic rates, and emotional health inputs.

Implementing Function Health in Daily Life

Applying Dr. Peter Attia’s Function Health approach starts with evidence-based daily routines and extends through consistent self-monitoring. You create lasting benefits and gain actionable insight by combining core habits with tracking systems.

Key Habits and Practices

Adopting practices from Function Health strengthens your metabolic and overall resilience.

• Steady-state exercise: Engage in zone 2 aerobic training, such as brisk walking or cycling, for 150–180 minutes weekly. This builds cardiovascular efficiency and supports fat metabolism.
• Strength training: Perform resistance exercises at least two times per week. Include compound movements like squats, deadlifts, and pull-ups to optimize skeletal muscle health.
• Consistent nutrition: Structure meals using high-fiber vegetables, protein sources such as fish or eggs, and healthy fats like olive oil. Limit added sugars and refined carbohydrates to stabilize insulin sensitivity.
• Daily sleep hygiene: Establish a sleep routine by keeping fixed bed and wake times. Diminish blue light exposure and control room temperature for deeper sleep cycles.
• Stress management: Practice mindfulness meditation or controlled breathing. Set 10-minute daily sessions to lower chronic cortisol and promote recovery.

Tracking Progress Over Time

Implementing Function Health requires regular evaluation anchored in real-time data.

• Biomarker monitoring: Order advanced blood panels quarterly to measure metrics including ApoB, hsCRP, fasting insulin, and hemoglobin A1c. Early detection guides precise intervention.
• Wearable technology: Use devices such as continuous glucose monitors and fitness trackers. Collect daily metrics like heart rate variability and sleep architecture to make informed adjustments.
• Personal logbooks: Record mood, movement, and nutrition in health journals. Identify patterns and adapt routines to target the strongest predictors of longevity.
• Ongoing adjustment: Align your interventions with changing biomarker trends rather than following static plans. Modify exercise, nutrition, or sleep protocols in response to specific biomarker shifts.
