Learn About Metabolic Health
Evidence-based educational content to help you understand your lab results and take control of your metabolic health.
Three Medical Paradigms
Every calculator shows your results through three different medical frameworks, helping you understand how perspectives differ.
Standard Medical
Traditional reference ranges used by most doctors and labs. Based on population averages and disease prevention thresholds.
Research Consensus
Derived from large-scale epidemiological studies. Important caveat: Most research populations followed standard dietary guidelines.
Metabolic Optimization
Interpreted through insulin and hormonal signaling rather than caloric balance. Accounts for metabolic adaptations in fat-adapted individuals.

Years insulin resistance can precede diabetes
The good news: Insulin resistance is often reversible with lifestyle changes. Early detection through markers like TG/HDL ratio and HOMA-IR can help you take action before progression to diabetes.
