• Overall health and resilience

Protocol Implementation

Morning HRV assessment:

• Take reading immediately upon waking
• Use consistent position (sitting or lying)
• 2-5 minute measurement duration
• Track trends over 7-day rolling averages

Training decisions based on HRV:

• High HRV (green zone): Proceed with planned intense training
• Normal HRV (yellow zone): Moderate intensity training acceptable
• Low HRV (red zone): Focus on recovery, light movement only

Advanced periodization:

• Weekly macrocycles: Plan high-intensity weeks during high HRV periods
• Monthly patterns: Track monthly HRV trends for longer-term planning
• Seasonal adjustments: Adapt training loads based on seasonal HRV changes
• Life stress integration: Reduce training load during high life stress periods

2. Continuous Glucose Optimization

Metabolic Flexibility Assessment

Testing protocol:

• Fasted glucose: Morning readings after 12+ hour fast
• Post-meal responses: 1-hour and 2-hour post-meal readings
• Exercise responses: Pre, during, and post-workout glucose
• Sleep glucose: Overnight glucose stability assessment

Food Testing Methodology

Systematic approach:

• Test one food at a time
• Control portion sizes and timing
• Note glucose peak, duration, and return to baseline
• Track symptoms, energy, and mood correlations
• Test foods multiple times for consistency

Optimal glucose targets:

• Fasting: 80-90 mg/dL for metabolic health
• Post-meal peak: <140 mg/dL, ideally <120 mg/dL
• Return to baseline: Within 2-3 hours
• Time in range: >90% of time between 70-140 mg/dL
• Glucose variability: Standard deviation <30 mg/dL

Advanced CGM Strategies

Meal timing optimization:

• Protein first: Eat protein before carbohydrates
• Vinegar protocol: 1-2 tbsp apple cider vinegar before meals
• Post-meal walks: 10-15 minute walks after eating
• Meal spacing: 4-5 hours between meals for glucose stability

Exercise optimization:

• Pre-workout glucose: 90-120 mg/dL optimal for performance
• Intra-workout fueling: Maintain 100-180 mg/dL during long sessions
• Post-workout: Monitor for reactive hypoglycemia
• Recovery nutrition: Time carbohydrate intake for glycogen replenishment

3. Sleep Architecture Optimization

Deep Sleep Enhancement

Tracking key metrics:

• Deep sleep percentage: Target 15-20% of total sleep
