7 Key Concepts
Reactive Healthcare System
A medical model focused on treating diseases once they manifest, rather than proactively preventing them or optimizing health before symptoms appear. This system often waits until conditions are advanced before intervention.
Proactive Prevention
An approach to health that involves actively monitoring biomarkers and making lifestyle or medical interventions early to prevent the onset or progression of chronic diseases, aiming to reverse decline rather than just manage illness.
N of One Medicine
A personalized medical approach that recognizes each patient as a unique individual, tailoring treatments and health strategies based on their specific biomarkers, genetics, and responses, rather than relying on population averages.
Carbohydrate Metabolism Disorders
A broad category of issues related to how the body processes carbohydrates, including insulin resistance, high or low blood sugar, and elevated insulin, which can precede type 2 diabetes by decades and contribute to many aging-related diseases.
Fasting Insulin
A critical biomarker that measures insulin levels after a period of fasting. It is important because elevated fasting insulin indicates insulin resistance and can signal metabolic dysfunction decades before blood sugar levels (like HbA1c) show signs of prediabetes or diabetes.
Free Testosterone
The biologically active form of testosterone, not bound to proteins, that is available to act on cells throughout the body. It is a vital hormone for both men and women, impacting muscle, memory, bone density, blood sugar, and heart health.
Epigenetics
The study of how environmental and lifestyle factors can influence gene expression without altering the underlying DNA sequence. This concept highlights that while we inherit a genetic 'rough draft,' our daily choices can change how those genes are expressed, impacting our health trajectory.
11 Questions Answered
The biggest myth is that you can wait until you're sick to address health issues. Chronic diseases develop over decades, with detectable biomarkers long before symptoms appear, making proactive intervention crucial.
While peak health is often in the late 20s to early 30s, biological, metabolic, and hormonal changes that undermine future health often begin in the 30s, becoming more palpable in the 40s and 60s.
The current medical system is primarily reactive, focusing on disease management rather than proactive health creation. It often uses broad 'normal' ranges for tests, misses early signs of decline, and lacks personalized, trend-based monitoring.
The five key biomarkers are fasting glucose, hemoglobin A1c (average blood sugar), fasting insulin, cholesterol risk ratio (total cholesterol divided by HDL), and free testosterone.
Fasting insulin is critical because it can indicate insulin resistance and carbohydrate metabolism disorders decades before an HbA1c test shows prediabetes or diabetes, offering an early opportunity for intervention.
Ideally, key biomarkers should be tracked at least twice a year, and potentially three to four times, especially when making lifestyle changes, to monitor trends and assess the effectiveness of interventions.
CGMs provide real-time data on how individual bodies respond to specific foods, movement, and lifestyle choices, highlighting personalized glucose fluctuations that can inform dietary adjustments and healthier habits.
Yes, testosterone is an essential hormone for women, impacting bone health, memory, cognition, muscle mass, and sexual function. Women also experience a decline in testosterone from their 30s, contributing to weight gain and other issues.
While optimizing sleep can prevent testosterone from falling, lifestyle changes like diet and exercise generally do not increase testosterone to optimal levels once decline due to aging begins. Medical intervention, such as HCG or testosterone replacement, is often needed for optimization.
Optimizing free testosterone can lead to increased muscle mass, loss of visceral and liver fat, normalized blood sugars, improved memory and cognition, better lipid profiles, increased energy, and enhanced libido and sexual function.
If not managed effectively, high doses of testosterone can lead to erythrocytosis (increased red blood cells), which can cause sluggishness and blockages. Regular monitoring and appropriate dosing are essential to mitigate this risk.
8 Actionable Insights
1. Prioritize Proactive Health Investment
Invest in keeping your body strong, healthy, and mentally sharp proactively, rather than waiting until you are sick, as chronic diseases build over decades and are detectable and reversible early on.
2. Track Key Biomarkers Regularly
Monitor critical biomarkers like fasting glucose, HbA1c, fasting insulin, cholesterol risk ratio, and free testosterone at least twice a year, or ideally three to four times, to understand your health trajectory and identify issues early.
3. Monitor Glucose with a CGM
Wear a continuous glucose monitor (CGM) for at least 14 days to understand your individual blood sugar response to different foods, activities, and lifestyle choices, as this knowledge is life-changing for personalizing diet and habits.
4. Eat Protein Before Carbohydrates
Consume protein first in a meal before carbohydrates to create a slower, more gentle rise in blood sugar and insulin, preventing sharp spikes and subsequent crashes that can lead to hunger and irritability.
5. Optimize Free Testosterone Levels
Consider optimizing free testosterone levels, for both men and women, especially from the 30s onwards, as it is critical for bone health, memory, cognition, muscle mass, and metabolic health, and can significantly improve quality of life.
6. Address Sleep for Hormone Health
Ensure adequate, deep sleep (over an hour of deep sleep and REM) as poor sleep can lower testosterone levels, even if other lifestyle factors are optimized. Addressing sleep issues can help improve hormonal balance.
7. Stop Eating Before Bedtime
Aim to stop eating about two hours before bedtime, as wearing a CGM can reveal how late-night eating affects blood sugar fluctuations and potentially disrupts sleep.
8. Understand Your Genetic Risks
Recognize that family history reflects genetic expression; if conditions like dementia, osteoporosis, heart attack, or stroke run in your family, you are at risk, and this knowledge should drive proactive health decisions.

Dr. Florence Comite
Decline is not inevitable, it's detectable. And because it's detectable, it's reversible.
Dr. Florence Comite
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.

We're living longer, but not better.
Dr. Florence Comite
The way we practice it today is about disease. It's reactive. So we're 10, 20, 30 years down the line already and we've been dealing with these conditions under the surface.
Dr. Florence Comite
I think of normal as a bad word because there's nothing that's normal.
Dr. Florence Comite
You are the architect of your own health. Making lifestyle change is always worth it because when you feel better, you live more.

2 Protocols
HCG Protocol for Men
Dr. Florence Comite- Administer a tiny shot (small needle) of HCG.
- Take the shot twice a week; once a week is insufficient.
- If resistance occurs, increase frequency to three times a week.
- Monitor pituitary hormones (LH and FSH) to assess responsiveness.
Macronutrient Order for Glucose Control
Dr. Florence Comite- Consume protein first (e.g., eggs, salmon).
- Then, add carbohydrates afterwards (e.g., sweet potatoes).
- This order helps sugar rise slowly, like a gentle mountain, with insulin following closely, preventing sharp spikes and drops.
