Metabolic Health
Weight, blood sugar, body composition
What is Metabolic Health?
Metabolic health encompasses how your body processes and uses energy. Optimizing it means managing weight, blood sugar, and body composition through evidence-based interventions, from tracking calories and hitting protein targets to advanced options like GLP-1 medications and continuous glucose monitors.
Metabolic health is foundational to longevity. Poor metabolic health, characterized by high blood sugar, excess visceral fat, and insulin resistance, is linked to virtually every chronic disease.
The good news: metabolic health is highly modifiable. Simple interventions like tracking what you eat, walking 10,000 steps daily, and hitting protein targets can transform your metabolic profile. More advanced approaches like time-restricted eating, Zone 2 cardio, and GLP-1 medications offer additional tools for those who need them.
This protocol organizes interventions from free, low-risk basics to more complex (but powerful) options.
Why Metabolic Health Matters
Metabolic dysfunction underlies most chronic diseases, diabetes, heart disease, and even some cancers. Research shows that metabolic health predicts all-cause mortality better than BMI alone.
Only 12% of American adults are metabolically healthy. But the markers are responsive to intervention: even modest improvements in diet and exercise can shift your metabolic profile significantly within weeks.

Metabolic Health Interventions
Foundation
Start here
Start here. These interventions are free or cheap, low-risk, and have strong evidence. They form the foundation that makes everything else work better.
Track calories/macros
Know what you're eating
10k steps daily
Basic daily movement
Protein target (0.8g/lb)
Build and preserve muscle
Reduce processed foods
Cut ultra-processed junk
Optimize
Level up
Once foundations are solid, these interventions offer additional benefits. They may involve supplements, devices, or more deliberate time investment.
Time-restricted eating
16:8 or similar fasting window
Zone 2 cardio (150min/wk)
Build aerobic base
Berberine or Metformin
Blood sugar support
Cold exposure
Activate brown fat
Advanced
For later
Higher cost and complexity. Often requires medical supervision. Only pursue once foundation and optimization tiers are established.
GLP-1 medications
Semaglutide, Tirzepatide
Continuous glucose monitor
Real-time glucose tracking
Retatrutide
Triple-agonist GLP-1
Frequently Asked Questions
What is metabolic health?
Metabolic health refers to how well your body processes energy. Key markers include blood sugar (fasting glucose, HbA1c), blood pressure, triglycerides, HDL cholesterol, and waist circumference. Being metabolically healthy means having optimal levels in all these markers without medication.
How do I know if I have good metabolic health?
Key markers of metabolic health: fasting glucose under 100 mg/dL, HbA1c under 5.7%, blood pressure under 120/80, triglycerides under 150 mg/dL, HDL over 40 mg/dL (men) or 50 mg/dL (women), and waist circumference under 40 inches (men) or 35 inches (women).
Do I need to track calories to lose weight?
Tracking isn't strictly required, but research shows it significantly improves outcomes. Even short-term tracking (2-4 weeks) builds awareness of portion sizes and caloric density. You don't need to track forever, just long enough to calibrate your intuition.
What is Zone 2 cardio?
Zone 2 cardio is low-intensity aerobic exercise where you can still hold a conversation. It primarily burns fat for fuel and builds mitochondrial density. Aim for 150-180 minutes per week. Examples: brisk walking, easy cycling, light jogging.
