How To Create The Scientifically Healthiest Diet (Ultimate Guide)
Howon Noh
Overview
This video outlines a five-level approach to creating a scientifically optimized diet, moving from universal principles to highly personalized strategies. It begins with establishing body composition goals and calculating macronutrient needs, emphasizing whole foods, meal timing, and toxin reduction. Subsequent levels delve into personalized insights from genetic testing, gut microbiome analysis, and food intolerance testing. The guide then progresses to optimizing health markers through blood work interpretation and continuous glucose monitoring, highlighting the impact of eating speed, exercise, and food order. The ultimate goal is to leverage comprehensive personal data for peak health and performance.

Chapters
- Establish a body composition target (e.g., body fat percentage) before focusing on calorie intake.
- Determine optimal macronutrient ratios: protein based on goals (bulking, cutting, maintaining), fat around 25% of calories, and carbohydrates filling the remainder.
- Prioritize food quality by consuming at least 80% whole foods and limiting processed items with long ingredient lists.
- Optimize meal timing by eating the largest meal earlier in the day and stopping at least 4 hours before bed to aid recovery.
- Minimize toxin exposure from cookware and cleaning products, and consider essential supplements.
This level provides a universal framework for healthy eating that addresses fundamental physiological needs and habits, forming the basis for all subsequent personalization.
For a 150 lb individual maintaining weight, the target is 120g protein, 65g fat (approx. 25% of 2400 calories), and the remaining calories from carbohydrates, adjusted based on activity level.
- Genetic testing can reveal individual predispositions to metabolizing caffeine, digesting lactose, and processing fats and carbohydrates.
- The CYP1A2 gene influences caffeine metabolism speed, dictating optimal cutoff times for consumption.
- The MCM6 gene determines lactose tolerance, suggesting alternatives for individuals with mutations.
- Genes like PP ARG and APOE affect whether your body prefers processing fats or carbohydrates, influencing optimal macro splits.
- MTHFR and COMT gene variants can impact the body's ability to utilize certain vitamins, necessitating specific supplement forms.
Genetics explain why standardized dietary advice may yield different results for different people, enabling more precise macro and food choices.
An APOE4 gene carrier might thrive on a higher-carbohydrate, lower-fat diet, while an APOE2 carrier might do better on a low-carbohydrate, higher-fat diet, even with the same calorie goals.
- Gut microbiome testing reveals the functional activity of gut bacteria, assessing inflammation, butyrate production, gut lining health, and diversity.
- High inflammation can be reduced by increasing fermented foods and decreasing refined carbs and processed oils.
- Adequate butyrate production, crucial for gut health and cognitive function, is supported by consuming cooled rice and less ripe bananas.
- Improving gut lining health involves removing irritants like alcohol and processed foods, and supporting it with collagen or zinc.
- Food intolerance testing, followed by an elimination and reintroduction process, identifies specific foods that cause adverse reactions like bloating or skin issues.
This level addresses how your unique gut environment and sensitivities impact nutrient absorption, energy levels, and overall well-being, allowing for targeted dietary adjustments.
If a food intolerance test shows reactivity to dairy, the process involves removing dairy for 3-4 weeks, then reintroducing it to see if symptoms like bloating or skin issues return.
- Key blood markers like fasting glucose, inflammation (HSCP), and heart disease risk (APOB) provide objective insights into metabolic health.
- Optimizing fasting glucose involves matching carbohydrate intake to activity levels, consuming more on training days and less on rest days.
- Reducing inflammation can be achieved by prioritizing omega-3 rich foods (wild fish, flaxseed), grass-fed meats, and specific supplements like curcumin and omega-3s.
- Lowering APOB risk involves shifting fats to olive oil and avocados, increasing soluble fiber intake, and potentially supplementing with berberine.
- Monitoring and optimizing testosterone and triglycerides involves ensuring adequate fat intake, sufficient zinc and Vitamin D, and appropriate carbohydrate management.
Analyzing blood work allows for the objective assessment of physiological responses to diet and lifestyle, enabling precise interventions to improve long-term health and prevent disease.
If fasting glucose is elevated, the strategy is to adjust carbohydrate intake based on daily activity: higher carbs on long run days (e.g., 440g) and lower on rest days (e.g., 165g).
- Continuous glucose monitoring (CGM) reveals how eating speed, food order, and specific food combinations impact blood sugar spikes.
- Eating slowly significantly reduces glucose spikes compared to eating the same meal quickly.
- Prioritizing protein and vegetables before carbohydrates in a meal lowers the overall glucose response.
- Certain food combinations, like high-sugar fruit after a heavy meal or refined carbs after high fat, can cause unexpected glucose spikes.
- CGM identifies individual 'safe' foods that might be problematic due to processing, timing, or combination, offering real-time personalized feedback.
This advanced level fine-tunes dietary choices by revealing the immediate physiological impact of eating behaviors and specific food pairings, leading to more stable energy and health.
Eating vegetables and protein first, followed by carbohydrates, leads to a more gradual glucose rise compared to consuming the same meal with carbohydrates first.
Key takeaways
- A scientifically healthy diet is built progressively, starting with fundamental principles and layering in personalized data from genetics, gut health, and metabolic markers.
- Body composition goals, not just calorie counts, should guide dietary planning.
- Macronutrient needs are individual and influenced by genetics, activity levels, and health goals.
- Food quality, meal timing, and toxin reduction are crucial foundational elements for overall health, regardless of specific macronutrient targets.
- Genetic predispositions can explain why certain foods or eating patterns affect individuals differently.
- Gut health significantly impacts nutrient absorption, inflammation, and cognitive function, making microbiome and intolerance testing valuable.
- Objective blood markers provide critical insights into metabolic health and disease risk, guiding targeted dietary adjustments.
- Real-time data from tools like continuous glucose monitors can reveal subtle yet impactful dietary dynamics related to eating speed, food order, and combinations.
