1h 33mKey Takeaway
Start tracking your fasting insulin now, not when you're sick. This single biomarker can reveal insulin resistance decades before diabetes symptoms appear, giving you years to reverse the trajectory through targeted lifestyle changes. Unlike waiting for your A1C to hit pre-diabetic levels, elevated fasting insulin shows your body struggling to maintain blood sugar control while everything still looks 'normal' on standard tests. Use this early warning to take action today.
Episode Overview
Dr. Florence Comite, a pioneering endocrinologist and clinical scientist, shares her revolutionary approach to proactive health management through five key biomarkers that predict aging patterns decades in advance. She explains why the current reactive healthcare system fails us, how insulin resistance develops silently for years before diabetes diagnosis, and why tracking trends in your biomarkers every 3-4 months—rather than annual checkups—is essential for reversing disease and maintaining vitality throughout life.
Key Insights
Your 30s Are the Metabolic Turning Point
While we can burn the candle at both ends in our 20s, biological changes accelerate in our 30s. Hormones begin declining, metabolism shifts, and conditions like heart disease and insulin resistance start developing—even if you're doing everything 'right.' This is when investing in your health matters most, not when symptoms finally emerge decades later.
Fasting Insulin Reveals Disease Decades Early
Fasting insulin changes 10-30 years before diabetes symptoms appear, yet almost nobody measures it. Elevated insulin indicates your cells are becoming resistant, forcing your pancreas to work harder to maintain normal blood sugar. By the time your A1C reaches pre-diabetic levels, you're already far down the disease pathway. Fasting insulin is the early warning system medicine ignores.
Normal Ranges Are Based on Sick Populations
Being told you're 'normal' is meaningless when normal is derived from population averages that include sick people. An A1C of 5.9 is technically normal in the UK but indicates you're one-tenth of a point from pre-diabetes and likely decades into metabolic dysfunction. Optimal health requires individual trending, not population comparisons.
CGMs Empower You to Own Your Health
Continuous glucose monitors reveal how your unique biology responds to specific foods, sleep patterns, stress, and timing of meals. One person's sugar might spike from a banana while another's doesn't budge; cookies might affect them inversely. This personalized data allows you to make targeted changes and see results in real-time, creating lasting behavior change that generic advice cannot.
Track Biomarkers 3-4 Times Yearly for Actionable Feedback
Annual checkups are too infrequent to connect lifestyle changes with biological outcomes. Checking biomarkers every 3-4 months lets you see if your interventions are working while you still remember what you changed. This feedback loop is essential for maintaining motivation and fine-tuning your approach to achieve optimal markers.
Notable Quotes
"Staying youthful, strong, and mentally sharp as you age is the most important investment you can make in yourself and for the people you love. Yet, so many accept physical and cognitive decline as unavoidable, doing little to interrupt the hallmarks of aging."
"There's nothing in the medical world that actually treats you proactively. It's all about you getting sick and it's a reactive health care system in most places in the world, certainly in the US and presumably in the UK."
"By the time modern medicine gets involved, you are way down the road to getting sick. Your heart attack has been brewing generally under the surface for decades. Insulin resistance is seen decades before flouride signs of diabetes."
"The biggest myth is that you can wait. You can wait until you're sick because we tend to reinforce that. Physicians feel that by looking at your tests, by understanding what's going on at the cellular level, we can just keep an eye on it or it's all in the normal range. And both of those statements are outrageously wrong."
"Somebody who has diabetes has the same risk of a heart attack as someone who's already had a heart attack. So, the effect of these sugary red blood cells on the heart, on the brain is really detrimental."
Action Items
-
1
Get Your Fasting Insulin Tested Now
Request a fasting insulin test (not just fasting glucose) at your next doctor's visit or through a private lab. This single marker can reveal insulin resistance years before standard diabetes markers show problems. Track it every 3-4 months to catch early changes.
-
2
Use a CGM to Discover Your Personal Food Responses
Wear a continuous glucose monitor for 2-4 weeks to learn which specific foods spike your blood sugar. Test the same foods at different times of day and in different combinations (e.g., carbs first vs. protein first). Use this data to personalize your diet based on your unique biology.
-
3
Track the Five Key Biomarkers Every 3-4 Months
Establish baseline measurements for fasting glucose, hemoglobin A1C, fasting insulin, cholesterol risk ratio (total cholesterol/HDL), and free testosterone. Retest every 3-4 months to see trends and verify that lifestyle changes are moving your markers in the right direction.
-
4
Stop Eating Two Hours Before Bedtime
Allow your body to clear metabolic waste from your brain and body by finishing your last meal at least two hours before sleep. This simple timing change can improve sleep quality, stabilize overnight blood sugar, and support cellular cleanup processes.
