Introduction to Medicine 3.0 and the Healthspan Mindset
Dr. Peter Attia's approach is rooted in what he calls "Medicine 3.0," a departure from the reactive, disease-centric model of mainstream healthcare (Medicine 2.0). Medicine 3.0 is a proactive, personalized strategy that uses advanced diagnostics and risk assessment to prevent chronic diseases—like heart disease, cancer, and type 2 diabetes—long before they manifest. This philosophy emphasizes maximizing healthspan, not just extending lifespan, to ensure that added years are high-quality and functional.
Attia argues that preparing for the "Centenarian Decathlon"—a personal list of physical tasks you want to be able to perform in your later years—is a more meaningful goal than simply chasing arbitrary fitness metrics. This mindset shifts the focus from short-term fixes to a sustainable, lifelong investment in your physical, mental, and emotional well-being.
The Four Pillars of Exercise
Exercise is perhaps the most powerful tool in Attia's longevity arsenal. His framework divides physical activity into four key pillars, each with a distinct purpose:
1. Stability
Stability is the foundation, focusing on training natural, efficient movement patterns. This helps prevent injury and allows for safe, effective performance in other exercises. Attia often uses Dynamic Neuromuscular Stabilization (DNS) exercises and focuses on core stability, foot strength (like toe yoga), and balance.
2. Strength
Strength training is considered a form of "retirement saving" for your muscles, helping to combat age-related muscle loss, or sarcopenia. Attia emphasizes building functional strength for everyday tasks, incorporating exercises like hip-hinging movements, weighted carries, and pulling motions. He advocates for progressive overload but emphasizes proper form to prevent injury.
3. Aerobic (Zone 2) Training
Zone 2 training is low-intensity, steady-state cardio performed for an extended period, typically at 65-75% of your maximum heart rate. This type of exercise builds mitochondrial health and efficiency, which is crucial for metabolic function and endurance. Attia recommends about four 45- to 60-minute Zone 2 sessions per week. Activities like rucking (walking with a weighted pack), cycling, or using a StairMaster are common examples.
4. Anaerobic (Zone 5) Training
Zone 5 training involves high-intensity interval training (HIIT) to boost VO₂ max, the maximum rate at which your body can use oxygen during exercise. A high VO₂ max is one of the most significant markers for longevity. Attia suggests one 30-minute VO₂ max session per week, consisting of four-minute all-out efforts followed by four minutes of rest.
A Nuanced Approach to Nutrition
Attia’s nutritional recommendations have evolved over time from a rigid ketogenic diet and extended fasting toward a more balanced, personalized strategy. His current approach prioritizes maintaining muscle mass and reducing body fat by focusing on three key “levers” for food intake:
- Dietary Restriction (DR): Eliminating junk food, processed items, sugar-sweetened beverages, and alcohol. This is a constant lever.
- Time-Restricted Eating (TRE): Limiting eating to a specific daily window. Attia now uses this flexibly rather than adhering to rigid, long fasts.
- Calorie Restriction (CR): Reducing overall calorie intake as needed to manage body composition.
His primary focus now is on high protein intake—roughly 1 gram per pound of body weight—to support muscle maintenance and growth. He also uses a continuous glucose monitor (CGM) to track his individual metabolic response to different foods.
Comparing Attia's Evolving Nutrition Strategies
| Feature | Early Protocol (e.g., 2011-2014) | Current Protocol (e.g., 2024-2025) |
|---|---|---|
| Dietary Focus | Rigid ketogenic diet (very low carb) | Balanced, high-protein diet with healthy carbs and fats |
| Fasting | Extended water fasts (7+ days), sometimes quarterly | More flexible time-restricted eating; long fasts are rare |
| Protein Intake | Less emphasis, secondary to keto goals | Primary focus, aiming for ~1g per pound of body weight |
| Calorie Tracking | Sometimes used to enforce restriction | Consistently tracked to manage overall energy balance |
| Junk Food | Strictly eliminated as part of keto | Strictly eliminated, considered a constant lever to avoid |
Optimizing Sleep for Restoration
Sleep is the foundation for all other longevity efforts. Attia views it as non-negotiable and prioritizes it with a deliberate routine. His core sleep rules include:
- Consistent Wake Time: Maintaining a fixed wake-up time, even on weekends, to regulate the circadian rhythm.
- Avoiding Evening Disruptors: Not eating or drinking alcohol within three hours of bedtime.
- Creating a Cool, Dark Environment: Using blackout curtains and setting the thermostat to a cool temperature (60-67°F).
- Limiting Blue Light: Avoiding screens for at least two hours before bed or using blue-light-blocking glasses.
- Heat Therapy: Using a sauna or hot bath before bed to trigger a rapid drop in body temperature, signaling the body to sleep.
- Targeted Supplements: Using specific supplements like magnesium L-threonate, glycine, and ashwagandha to support rest.
Cultivating Mental and Emotional Health
Attia is increasingly vocal about the critical role of emotional health in longevity, describing it as a key element of living better. His protocol includes proactive strategies for mental well-being, acknowledging that you can't be a "kick-ass 100-year-old" without joy, purpose, and emotional resilience.
Strategies he discusses include:
- Addressing Trauma: Recognizing and working through past emotional trauma through therapy.
- Mindfulness and Self-Reflection: Practicing mindfulness exercises and emotional "homework" to process feelings rather than dissociate from them.
- Meaningful Relationships: Fostering strong, supportive relationships as a buffer against emotional distress.

Strategic Supplementation
Attia approaches supplements with a data-driven, evidence-based mindset, viewing them as a tool to fill nutritional gaps rather than a substitute for diet and exercise. His personal regimen, which he emphasizes is not one-size-fits-all, includes common supplements supported by research, with dosages adjusted based on regular biomarker testing.
Examples of supplements he has discussed include:
- Omega-3s (EPA and DHA): For brain and cardiovascular health.
- Vitamin D3: To support immune function and bone health, especially with insufficient sun exposure.
- Magnesium: Specifically L-threonate for cognitive function and glycinate for sleep.
- Creatine: For its roles in muscle and neuroprotection.
- Probiotics: Such as Akkermansia muciniphila, to support gut health.
- Theracurmin: A highly absorbable form of curcumin for its anti-inflammatory properties.
- Ashwagandha and Glycine: For promoting better sleep.
Conclusion: A Personalized, Proactive Framework
The Peter Attia longevity protocol is not a rigid set of rules but a flexible, science-based framework built around four core pillars: exercise, nutrition, sleep, and emotional health. By adopting the principles of Medicine 3.0, prioritizing healthspan over mere lifespan, and consistently measuring biomarkers, individuals can proactively reduce their risk of chronic disease and maximize the quality of their later years. The protocol's strength lies in its personalized nature, encouraging individuals to use data and evidence to optimize their unique path toward a healthier, more vibrant life.
