Fasting insulin – this is one of the most crucial, and most overlooked biomarkers in medicine because it reveals how hard your body is working to stabilize glucose. “This biomarker is rarely ordered by physicians, yet it is an early warning sign of insulin resistance and prediabetes, giving you a heads up about brewing metabolic issues decades before the usual fasting glucose.”
Fasting glucose – This test measures blood sugar after fasting overnight to screen for prediabetes or diabetes.
HbA1c – This measures average blood sugar levels over about three months, and while “normal” is considered below 5.7%, this expert likes to see it under 5.0%. She explains, “Once your hemoglobin A1c moves up above that, it signals changes in your system’s carbohydrate management, especially beyond 5.6%, at which you have become prediabetic with metabolic dysfunction.”
Cholesterol risk ratio – This is your total cholesterol and under two is “optimal,”
Free testosterone – Both women and men need testosterone, which “drives energy, libido, muscle mass, metabolism and mood.”
Longevity experts recommend starting to monitor these between the ages of 25 and 30 so you establish a baseline, then track the changes over time. BUT it’s never too late to live healthy.
