Best Ways to Measure Blood Sugar and Metabolic Health: CGM and Lab Tests

Understanding Metabolic Health

• 💡 Good metabolic health is characterized by stable energy levels throughout the day, a healthy body fat percentage, good lean body tissue, and strong muscle building capacity.
• ✅ It also includes healthy blood work markers such as triglyceride levels, insulin levels, beneficial HDL cholesterol, and healthy blood pressure.
• 🚀 Achieving good metabolic health significantly lowers the risk of all-cause morbidity and mortality, increasing the chances of living a long and healthy life.

Continuous Glucose Monitoring (CGM)

• 🩸 A Continuous Glucose Monitor (CGM) offers a painless, non-invasive way to track blood sugar levels 24/7, unlike traditional finger pricks.
• 💻 CGMs provide real-time insights into how your body responds to food, stress, caffeine, and sleep, with software allowing you to log meals and see their impact.
• 📈 The goal is to keep blood sugar within a healthy range, ideally not jumping more than 20-30 points after a meal and returning below 100 mg/dL within a few hours.
• 🔗 Companies like Theia Health offer CGMs without a prescription, providing daily metabolic scores based on your glucose data.

Key Blood Work Biomarkers

• 🔍 Fasting insulin levels are crucial, as high insulin can indicate insulin resistance even with normal blood sugar; a healthy range is typically between 2-6 µU/mL.
• 🧬 Hemoglobin A1C (HbA1C) measures the glycation of red blood cells, with a healthy range generally between 4.5% to 5.2%; levels of 6% or higher indicate diabetes or pre-diabetes.
• ⚗️ Lactate Dehydrogenase (LDH) indicates how well your body utilizes glycolysis for energy; a range of 140-180 is considered healthy, with higher levels suggesting poor mitochondrial function and lower levels potentially indicating hypoglycemia.

Integrating Monitoring Methods

• 📊 While CGMs provide excellent real-time data, blood work offers a valuable complementary view of metabolic health over longer periods.
• 🎯 Combining CGM insights with lab tests like fasting insulin, HbA1C, and LDH provides a comprehensive understanding of your metabolic status and helps guide lifestyle modifications.
