Optimizing the
human system

As we age, some cells stop dividing and become senescent. Think of them as zombie cells — alive but no longer functional, and releasing harmful chemicals that affect surrounding cells. Removing these zombie cells through protocols such as fasting, exercise or using senolytic compounds (like quercetin and fisetin found in onion) can help keep tissues healthier.

Fasting, exercise and senolytic compounds (quercetin, fisetin) to clear senescent cells.

Autophagy is the process of clearing out damaged cellular components, while apoptosis is the controlled death of old or damaged cells. Both are essential for maintaining cellular health. Strategies like intermittent fasting and supplements like spermidine can trigger autophagy and help the body clean out cellular "junk". Nrf2 activation (via compounds like sulforaphane) promotes the production of detoxifying enzymes that help eliminate toxins or harmful byproducts that accumulate over time.

Intermittent fasting, spermidine and Nrf2 activation (sulforaphane) to maintain cellular health.

Stem cells are responsible for repairing and regenerating tissues. With age, stem cell numbers and activity decrease, meaning our body repairs damage more slowly. Fasting and specific diets (like the Fasting-mimicking diet from Dr. Valter Longo) can help stimulate stem cell production. Advanced therapies like stem cell injections are available in most places, but fasting is a more accessible option to boost stem cell activity.

Our DNA is like our body's instruction manual, but over time it gets damaged from events like pollution, UV radiation or natural metabolic processes. This damage accumulates, causing cells to function less effectively. Maintaining DNA stability and supporting DNA repair mechanisms is a key element to stop or reverse aging. Boosting NAD+ with compounds like NMN, NR or apigenin can help. Measure NAD+ levels using a basic test to eventually supplement yourself.

Telomeres are protective caps at the ends of your chromosomes. Every time a cell divides, telomeres get a little shorter, and when they're too short, the cell can no longer divide. Shorter telomeres are linked to aging and disease. Lifestyle choices like regular exercise, stress reduction and restful sleep have been shown to slow down telomere shortening. TA-65, a compound derived from astragalus root, has been shown to activate telomerase, the enzyme responsible for adding length to telomeres. Use a test like TeloYears to track your cellular age based on telomere length.

Exercise, stress reduction, sleep. TA-65 (astragalus-derived) to activate telomerase.

Angiogenesis is the process of forming new blood vessels, an essential step to deliver oxygen and nutrients to tissues. Nitric oxide (NO), a molecule produced naturally in the body, plays a role by regulating angiogenesis and improving blood flow everywhere in the body. Boosting NO levels can be achieved via aerobic exercise, consumption of nitrate-rich foods like beetroot and leafy greens, and supplements such as L-citrulline or L-arginine, which act as precursors for NO production.

Aerobic exercise, nitrate-rich foods (beetroot), L-citrulline and L-arginine supplementation.

Mitochondria are the powerhouses of the cells, generating the energy you need to live. As we age, mitochondria become less efficient, leading to fatigue, muscle weakness and slower recovery. Supporting mitochondrial health with exercise is really important. The best types of exercise for this are HIIT and resistance training, which encourage the body to produce new mitochondria. Supplements like CoQ10 and PQQ have also been shown to support mitochondrial function.

HIIT and resistance training. CoQ10 and PQQ supplementation.

Over time, proteins in cells can become misfolded or damaged, disrupting cell function. In a youthful and well functioning body, these misfolded proteins are broken down and recycled, but aging slows down this cleaning process, leading to cellular clutter. Fasting and caloric restriction trigger autophagy, where cells clean up damaged proteins. Incorporating periodic fasting or intermittent fasting can help maintain cellular health.

Fasting and caloric restriction trigger autophagy to clear misfolded proteins and reduce cellular clutter.

Epigenetics involves changes in the way genes are expressed without changing the DNA itself. Age-related epigenetic changes can activate "bad" genes and turn off "good" ones, leading to aging. Exercise, a clean diet, caloric restriction and supplements like resveratrol (found in grapes and red wine) can help maintain youthful gene expression, keeping cells functioning optimally. Estimate your biological age based on DNA methylation patterns using DunedinPACE.

Nutrient-sensing pathways, including insulin/IGF-1 signaling, mTOR (should be balanced: low during fasting, elevated in growth phases) and AMPK (optimal activation in fasting/exercise states), are vital regulators of metabolism and play a significant role in the aging process. These pathways detect and respond to nutrient availability, adjusting cellular and metabolic activities accordingly. By modulating these pathways through dietary interventions (calorie restriction, fasting, low-protein diet, ketogenic diet, high-fiber diet) or pharmacological methods (berberine, curcumin, resveratrol), it's possible to slow down age-related cellular damage.

Modulate insulin/IGF-1, mTOR and AMPK via calorie restriction, fasting, ketogenic diet, and compounds like berberine and curcumin.

Bodies develop low-level, chronic inflammation, often without us even realizing it. This type of "silent inflammation" speeds up aging and is linked to most major diseases. Acute inflammation is beneficial; chronic inflammation is detrimental. Combat inflammation through anti-inflammatory foods (fatty fish rich in EPA/DHA, leafy green vegetables and spices), regular exercise and optimal sleep. Omega-3 supplements and curcumin are particularly anti-inflammatory. Measure your level of CRP (C-reactive protein) to evaluate the inflammation in your body.

Anti-inflammatory diet (EPA/DHA, leafy greens, spices), optimal sleep. Measure CRP.

Glycation is when sugar molecules bind to proteins or fats, forming harmful compounds called AGEs (Advanced Glycation End-products) that lead to rigid, less elastic tissues. Reducing sugar intake, more particularly high-glycemic foods, and increasing intake of antioxidant-rich foods is the best strategy to reduce AGEs. Antioxidants also have the capacity to break down AGEs, protecting the cells. Measure blood glucose and HbA1c, which correspond to long-term blood sugar.

Reduce high-glycemic foods. Track HbA1c and fasting glucose.

Hormones like testosterone, estrogen, growth hormone and melatonin naturally fluctuate with age, impacting everything from muscle mass to mood to sleep quality. Balancing the key hormones is a necessity for vitality. Hormone replacement therapy (HRT) under medical supervision is a possibility, but you can also support your hormones naturally with resistance training, proper nutrition and supplements like Tongkat ali and Horny goat weed. Check your hormone levels (testosterone, estrogen, prolactin) during your yearly blood test.

Free radicals are molecules that can damage cells (a natural byproduct of metabolism). When free radicals accumulate faster than your body can handle, they cause oxidative stress leading to dysfunction. Beta-alanine, by increasing carnosine levels, contributes to anti-aging processes primarily through its role as an acid buffer against lactic acid build-up in cells, particularly in muscle tissue. Polyphenols from colorful fruits and vegetables help neutralize free radicals. Glutathione, vitamin C and alpha-lipoic acid are powerful choices for their antioxidant effects.

Your circadian rhythm is your internal clock. It controls sleep, energy and even hormone production. Disrupting this rhythm (through irregular sleep schedules, blue light exposure at night, etc.) accelerates aging. Maintaining a regular sleep-wake cycle, getting morning sunlight and avoiding blue light before bed can help keep the circadian rhythm in sync, supporting better overall health. Use a sleep tracker (Whoop or Oura) to monitor sleep.

Cells communicate less effectively with time, which can result in uncoordinated responses to damage and contribute to immune system decline. Hormesis (small, controlled stresses induced from exercise, cold/heat exposure, plant toxins or fasting) can reset cell communication. Additionally, anti-inflammatory practices reduce noise in cellular signals.
