Heart Disease Doesn't Start in Your Heart—It Starts Here | Dr. Florence Comite

Key wellness strategies & self-care / productivity tips from the discussion

1) Prevent disease decades earlier (focus on early “biomarker emergence”)

• Don’t wait for symptoms or emergency events (e.g., heart attack/diabetes diagnosis).
• Chronic diseases are described as beginning 20–50 years before they show up clinically—often at the metabolic/cellular level.

2) Use a “health story” + biomarker approach (personalized, not one-size-fits-all)

• Health planning should be based on:
  • Family history
  • Current biomarker trends
  • Lifestyle context
• This is framed as an “N-of-one” approach—tracking individuals over time to identify their real pattern.

3) Her “5 key biomarkers of health” (starting template)

• Fasting sugar
• Hemoglobin A1C (average sugar over ~100 days)
• Fasting insulin (an early marker; can show insulin resistance before A1C changes)
• Cholesterol risk ratio (noted as total cholesterol / HDL; risk if > 2)
• Free testosterone (used in women and men; emphasized as often overlooked in women)

4) Heart disease risk: treat aggressively by addressing sugar, cholesterol, inflammation, and hormones

• Diabetes/sugar issues are described as the biggest driver of heart attacks.
• She emphasizes looking beyond standard cholesterol panels, including:
  • ApoB
  • Lp(a)
• Vascular inflammation/endothelial stress markers mentioned:
  • hs-CRP (high-sensitivity C-reactive protein)

5) Blood sugar control: watch variability and insulin resistance, not just yearly averages

• She strongly supports continuous glucose monitors (CGMs) to see:
  • Glucose “roller-coaster” patterns
  • Stress-related spikes
  • Real-time impact of habit changes
• Annual blood draws may be misleading because they miss fluctuations.
• Mechanisms highlighted:
  • Glycation (sugar damage to cells)
  • Endothelial stress → chronic inflammation
  • Links to “diseases of aging” (including framing dementia as “diabetes type 3” and osteoporosis risk)

6) Lifestyle “sequence” for best results (sleep → food → exercise)

She reorders priorities to:

1. Sleep (paramount)
2. Food
3. Exercise - She also notes that stress/anxiety is a major missing piece affecting cortisol and glucose.

7) Practical sleep self-care tactics

• Focus is on quality deep sleep, not only total hours.
• Simple interventions mentioned:
  • Deep breathing / “reset” rituals (including reminders via an Apple Watch)
  • Meditation to reduce cortisol effects (including references to gene-expression impacts)
• Sleep is framed as a direct lever for metabolic health:
  • Less sleep → more cravings via ghrelin

8) Exercise and muscle preservation (especially for metabolic health and bone)

Resistance training

• 2–3 times/week for both men and women to build/maintain muscle.
• Preserving muscle supports glucose handling (more capacity to manage sugar).

Weight-bearing aerobic movement

• Walks and other weight-bearing activity are emphasized for bone support.
• Suggested timing:
  • Take a quick walk soon after eating (rather than waiting ~1 hour), based on referenced insulin-response timing.

Bone health

• Osteoporosis prevention mentioned includes:
  • DEXA scans earlier than menopause, encouraging women—when feasible—in their 20s–30s
  • Resistance training + weight-bearing activity

9) Don’t fear “diet perfection”; use moderation and personalization

• Discourages all-or-nothing dieting anxiety.
• Diet matters, but she says it’s not the biggest driver compared with sleep.
• Meal strategy:
  • Start meals with protein, fat, and fiber before carbs
• Sweet craving moderation ideas:
  • Pair cravings with protein/fats (e.g., nuts/cheese-based options instead of sugar-only)

10) Stress reduction as a metabolic intervention

• Cortisol is described as driving:
  • Central/visceral fat gain
  • Higher glucose readings (CGM examples included where stress spikes glucose)
• Tactics mentioned:
  • Meditation
  • Chi/advanced relaxation modalities (referred to as “chiang/raiki-like” work)
  • Deep breathing exercises

11) Hormone awareness (especially testosterone and estrogen transitions)

• Men: testosterone declines about 1–3% per year starting in the 30s (framed as linked to muscle loss and metabolic risk).
• Women: estrogen is described as heart-protective; risk rises during perimenopause/menopause.
• Hormone therapy concerns are addressed with emphasis on:
  • Individualized risk/benefit
  • Using appropriate sources

12) DEXA and osteoporosis: calcium nuance

• Calcium supplements are strongly positioned as not a default.
• Calcium use should depend on context (including vitamin D + K2).
• Emphasis on:
  • Vitamin D testing and adequacy
  • K2 to reduce risk of inappropriate calcium deposition
• Re-test vitamin D after adjustments.

13) Supplement/medication stance (GLP-1s as a tool, not a one-size solution)

• GLP-1 medications are described as potentially powerful—“antibiotics of the 21st century”—with life- and disease-modifying potential beyond weight loss.
• Clinical stance: judicious use, with person-specific risk/benefit (“end of one”).
• Also noted: concerns that people may use GLP-1s too ubiquitously without sufficient depth of knowledge.
