Final Advice for Taking Control of Your Health

Food as Information

Food is not merely calories or energy, but rather information that directly influences and changes your biology in real-time. This information impacts hormones, brain chemistry, the microbiome, the immune system, mitochondrial function, and stress hormones.

Glycemic Load

This refers to the total impact a meal has on your blood sugar. It's not just about individual ingredients but the overall composition of the meal, where adding fat, protein, and fiber can reduce the blood sugar spike from carbohydrates.

Hungry Fat

This concept describes belly fat that, once stored due to high insulin levels, makes you hungrier and slows your metabolism. It becomes difficult to release, contributing to a vicious cycle of weight gain and metabolic dysfunction.

FLC Syndrome (Feel Like Crap Syndrome)

A common constellation of subtle symptoms such as fatigue, brain fog, digestive issues, joint aches, headaches, poor sleep, and mild depression. These symptoms are often linked to inflammation and can resolve quickly by addressing dietary triggers.

Network/Systems Medicine

Also known as Functional Medicine, this approach seeks to identify the multiple root causes driving a particular health condition, rather than just treating symptoms. It emphasizes multi-modal treatments including diet, exercise, stress management, sleep, and targeted nutritional support.

Continuum of Disease

The understanding that many chronic diseases, such as diabetes, hypertension, and autoimmune conditions, develop gradually over time through various 'pre-' stages. Early identification of markers in these stages allows for intervention before full-blown disease manifests.

Autogens

A term for autoimmune-inducing toxins. These environmental factors, such as pesticides, heavy metals, and glyphosate, can trigger or exacerbate autoimmune diseases by causing inflammation and damaging the gut microbiome.

?
How should we rethink breakfast to optimize metabolic, gut, and longevity health?

Instead of starting the day with sugar or refined starches (which act like sugar), prioritize protein and healthy fats. This prevents blood sugar spikes, insulin surges, and subsequent cravings, leading to better metabolic health and sustained energy.

?
What is the relationship between our breakfast choices and our stress levels?

Eating sugar and starch for breakfast can act as a physiological stressor, increasing levels of stress hormones like cortisol and adrenaline. Chronically elevated cortisol can lead to belly fat, high blood pressure, diabetes, muscle and bone loss, and cognitive impairment.

?
How addictive are certain foods, and what is their impact on the brain?

According to the Yale Food Addiction Scale, 14% of adults and children are biologically addicted to food, experiencing withdrawal and cravings. Studies show that quickly released, high-sugar carbohydrates can activate the brain's addiction and pleasure centers, similar to cocaine or heroin.

?
Why should people consider cutting out gluten and dairy, even if they don't have celiac disease?

Modern wheat and dairy have been significantly modified, leading to higher gluten protein content in wheat and inflammatory A1 casein in dairy. These can cause leaky gut, inflammation, and various sensitivities, contributing to issues like digestive problems, skin issues, and autoimmune conditions, even without full-blown celiac disease.

?
Why is medical education often lacking in nutrition training?

Despite food being a primary cause and cure for many modern diseases, medical students often learn little about practical nutrition, the microbiome, insulin resistance, or environmental toxins. This gap means doctors are not equipped to address the root causes of many common ailments.

?
Why are 'normal' lab ranges often problematic, and what are optimal ranges for key biomarkers?

Traditional 'normal' lab ranges are statistical averages of a sick population, not indicators of optimal health. For example, an HbA1c above 5.0% or fasting insulin above 5 mIU/L, while sometimes considered 'normal' by labs, can indicate increased risk for disease, whereas optimal levels are much lower.

?
What are some early signs of autoimmune disease, and what can be done about them?

Early signs can include a positive ANA (anti-nuclear antibody) or thyroid antibodies, which indicate latent autoimmunity. Addressing root causes like microbiome disturbances, leaky gut, food sensitivities (e.g., gluten), and environmental toxins can help prevent progression to full-blown autoimmune disease.

?
How can individuals effectively detoxify from environmental toxins?

Effective detoxification involves reducing exposure to toxins (e.g., clean household products, organic food, filtered water, avoiding plastics) and maximizing excretion through the 'pee, poop, and perspire' system. This includes staying hydrated, consuming plenty of fiber and phytonutrients, and using sauna therapy or regular sweating.

1. Pay Attention to Body Signals

Regularly check in with your body by asking about your stomach, energy, skin, brain function, and sleep to understand your health status and be the CEO of your own health.

2. Prioritize Protein & Fat for Breakfast

Start your day with protein and fat (e.g., an omelet, protein shake) instead of sugar or refined starches to optimize metabolic health, prevent blood sugar swings, and reduce cravings and overeating.

3. Reset Metabolism with 10-Day Detox

To break the cycle of hunger, fat storage, and metabolic dysfunction, eliminate starch and sugar for a period, such as with a 10-day detox diet, to reset your metabolism.

4. Follow 10-Day Detox Protocol

For 10 days, eliminate sugar, starch, ultra-processed food, alcohol, and caffeine, while consuming real foods like lots of vegetables, nuts, seeds, good quality protein, good fats (avocados, olive oil), and low-starch berries.

5. Reintroduce Foods Systematically

After an elimination period, reintroduce foods one at a time, slowly (e.g., three days per food), to identify specific triggers that cause adverse physical reactions.

6. Listen to Your Body’s Feedback

Trust your body as the ‘smartest doctor’ by listening to its feedback when reintroducing foods or making dietary changes, as it will signal what works best for you.

7. Focus on Food Quality

Prioritize the quality of calories over just the quantity, as the information in food profoundly impacts your hormones, brain chemistry, microbiome, and immune system in real-time.

8. Eat a Non-Stressful Diet

Choose foods that do not physiologically stress your body, as sugar and starch can raise stress hormones like cortisol and adrenaline, leading to negative long-term health effects.

9. Prioritize Foundational Health Pillars

Address the four pillars of health—food, movement, sleep, and stress—starting by optimizing your diet, then observing which symptoms remain to identify underlying issues.

10. Consistent Small Health Investments

Adopt a philosophy of ‘steady wins the race’ by consistently investing small efforts daily into your diet, exercise, and stress management, as these foundational practices yield significant long-term health dividends.

11. Optimize Vitamin D Levels

Aim for Vitamin D levels of at least 45 ng/dL (ideally 75-100 ng/dL) to support bone density, cardiovascular health, brain health, and immune function, potentially reducing flu risk by 75%.

12. Maintain Fasting Insulin Below 5

Strive for a fasting insulin level of 5 or less, as this is ideal for metabolic health; levels between 5-10 are intermediate, and above 10 are indicative of significant insulin resistance.

13. Target Optimal HbA1c

Aim for an HbA1c level of 5.5% or less, as this indicates optimal average blood sugar and significantly reduces the risk of various chronic diseases.

14. Monitor Triglyceride/HDL Ratio

On your basic cholesterol checkup, monitor your triglyceride to HDL ratio; if it creeps over 1, 2, or 3, it indicates increasing insulin resistance and higher risk of heart attack.

15. Optimize ApoB Levels

Aim for ApoB levels under 90, ideally under 70, and potentially under 50 if you have existing cardiovascular disease, as ApoB is a highly predictive marker for heart disease risk.

16. Monitor Fasting Blood Sugar

Pay attention to your fasting blood sugar; if it’s between 85-100 mg/dL (American units), you’re trending towards dysregulation, and if it’s over 100 mg/dL, you’re likely already in metabolic trouble.

17. Assess Belly Fat as Health Indicator

Use the presence of belly fat as a strong visual indicator of potential insulin resistance and metabolic issues, even without a blood test.

18. Enhance Natural Detoxification

Support detoxification by staying hydrated, consuming fiber (flax, chia seeds) and magnesium for regular bowel movements, eating detoxifying phytochemicals (broccoli family, garlic, onions, colorful fruits/vegetables), using sauna therapy, and considering N-acetylcysteine.

19. Sweat & Regular Bowel Movements

Engage in activities that promote regular sweating (if sauna is not available) and ensure consistent bowel movements to excrete toxins from the body.

20. Reduce Toxin Exposure

Actively reduce your exposure to environmental toxins by using air filters, filtering your water, being mindful of air quality (e.g., using a mask in polluted areas), and avoiding touching receipts.

21. Minimize Household & Food Toxins

Clean up household products, prioritize organic foods, filter your water, use an air filter in polluted environments, and avoid plastic cups and bottles to reduce overall toxin exposure.

22. Choose European Wheat Products

If sensitive to gluten, consider consuming wheat products from Europe, as they often use different wheat varieties (non-dwarf), avoid glyphosate, and employ longer leavening processes like sourdough, which can be less inflammatory.

23. Address Root Causes of Symptoms

If eliminating inflammatory foods doesn’t resolve symptoms, consider deeper root causes like heavy metals, mold, or other serious conditions, as these may require further investigation.

24. Basic Supplementation & Lifestyle

If on a budget, take a good multivitamin, a good fish oil (1g EPA/DHA daily), and 2,000-4,000 IU of Vitamin D3 (with K2 if possible) to cover common deficiencies, alongside eating protein/fat for breakfast, cutting starch/sugar, and regular movement.

25. Treat Your Body Like a Racehorse

Apply the same high standards to your own and your children’s diet as you would to a valuable racehorse, avoiding ultra-processed foods that you wouldn’t feed to pets.

26. Make Conscious Health Choices

Once you understand how certain foods or habits (e.g., alcohol, ice cream) impact your body, make conscious choices about their consumption, informed by that knowledge, rather than acting unconsciously.

27. Start Small, Daily Changes

Implement small daily changes to your health habits, as these compound over time and can lead to significant improvements, and it’s never too late to begin.

28. Use Food as Medicine

Recognize that food acts as medicine to support longevity, energy, moods, and happiness, influencing your biology in real-time.

29. Vagus Nerve Stimulation for Stress

Consider using a vagus nerve vibratory stimulator for a few minutes daily to achieve a significant stress reduction and reset your nervous system.

30. Avoid Oatmeal as Primary Breakfast

Be cautious with oatmeal for breakfast, as even steel-cut oats can raise insulin, adrenaline, cortisol, blood sugar, and triglycerides, leading to blood sugar crashes and increased food intake later in the day.

Essentially, the world is eating dessert for breakfast.
