Wellness and Self-Improvement

Key wellness & prevention strategies (from Dr. David Perlmutter)

1) Aim for personalized medicine using biomarkers + your “life code”

Use data to tailor recommendations to you, including:

  • Genome (e.g., via 23andMe + interpretation tools)
  • Microbiome (changes can be tracked frequently)
  • Lifestyle + geography (what’s available, how you live)

2) Track metabolic and brain-inflammation risk markers

Suggested markers include:

  • Homocysteine (a risk factor tied to Alzheimer’s)
  • Vitamin D
  • Fasting glucose / blood sugar
    • Finger-stick checks ~1–2x/week may be sufficient
    • He calls daily monitoring “overkill”
  • Hemoglobin A1C (“average blood sugar”)
    • Avoid thinking “lower is always better”
    • Mentions a possible U-shaped risk: “too low” insulin/A1C can be harmful (discussed notably for women)
    • Suggests an “optimal” A1C range around ~5.0 to 5.3/5.4
  • Ketones
  • Consider whether you’re getting enough dietary fat (especially relevant for some vegan diets)

3) Exercise to reduce dementia risk—especially aerobic

  • Aerobic training can increase BDNF (brain-derived neurotrophic factor)
  • Suggested dose:
    • 20 minutes/day, 5 days/week (ideally more)
    • Target intensity: ~(180 − age) heart-rate guidance (with clinician approval)
  • Claims the exercise → BDNF pathway supports:
    • Neurogenesis (new brain cell growth; discussion emphasizes hippocampus and more)
    • Neuroplasticity/synaptic connectivity
    • Brain remodeling through synaptic pruning (“neurons that fire together wire together…”)

4) Target inflammation by controlling gut barrier health

Many chronic diseases (including Alzheimer’s, diabetes, autism, and cancer) are framed as strongly linked to inflammation.

  • Uses LPS (lipopolysaccharide) as a marker of gut permeability/leakiness
  • Emphasizes that the gut lining is a “gatekeeper” for inflammatory cascades

5) Gut microbiome interventions (probiotics → FMT examples)

  • Discusses Fecal Microbial Transplant (FMT) as a therapy with established safety/efficacy in certain cases, notably C. diff
  • Includes an autism case story approach:
    • Start with probiotic enemas
    • If insufficient, consider FMT from a screened donor
  • Mentions research/claims of improvement in autism-related outcomes in interventional work

6) Dietary “inputs” as signals to gene expression (not just macros)

  • Supports a paleo-style principle: match environmental signals to what your genome evolved for
  • Highlights how plant-derived RNA in exosome form may influence gut bacteria gene expression
  • Key dietary warnings mentioned:
    • Sugar/carbohydrate excess → glycation → inflammation
    • Artificial sweeteners may harm the microbiome
      • Example: sweeteners in coffee associated with obesity/type 2 diabetes risk in a large French study
    • Criticizes a vague “sweet spot” concept—prefers “optimize” rather than aim for a generic target

7) Medication skepticism: focus on root cause rather than symptom suppression

  • Claims Alzheimer’s drugs don’t work and may worsen decline (based on his summary of an AMA-published meta-analysis)
  • Critiques statins via linked concerns:
    • Increased risk of type 2 diabetes in studies he cited
    • “Statin brain”/cognitive effects claims
    • Argues cholesterol has essential roles (including in the brain)
    • States LDL risk depends on factors like oxidation/glycation, not just total LDL
    • Suggests testing for oxidized or glycated LDL if possible (not routinely done in many labs/clinics)

8) Mindset/self-care framing: act to rewrite future physiology

  • Lifestyle choices are repeatedly linked to gene expression, brain remodeling, and long-term outcomes
  • Emphasizes “connection” as the overarching behavior:
    • Connection to people, genome, microbiome, family, community, planet
