Prioritize Fasting Insulin for Metabolic Health

Monitoring fasting insulin levels is crucial for assessing metabolic flexibility, as these levels can reveal underlying issues often missed by analyzing blood sugar or hemoglobin A1c. Low fasting insulin levels, particularly under two, indicate good metabolic health, while levels of ten or above signify insulin resistance, suggesting either excessive carbohydrate or protein intake. Importantly, fat consumption does not influence insulin levels, making it a potentially safer dietary option for maintaining metabolic health.
