Beyond Lifespan Longevity Podcast (English Edition)

What matters more: the diet you follow or the foods you choose within it?

Community question: Can you build muscle on a vegetarian diet? A discussion of protein sources, bioavailability and meeting protein needs without meat.

Practical takeaway: Plan at least one daily meal around minimally processed foods, with both a protein source and a fiber source. The idea is recognizable ingredients—not a meal containing only one ingredient.

In conventional dentistry, routine check-ups often focus solely on detecting cavities. What is frequently overlooked is that old amalgam fillings, root canal-treated teeth, or silent areas of inflammation following wisdom tooth surgery may act as chronic stressors on the entire body and fuel so-called inflammaging processes.

In this episode, Mario and Max join biological dentist Dr. Fabian Schick to explore the connections between oral and systemic health. They examine the scientific debate surrounding fluoride, introduce hydroxyapatite as a biocompatible alternative, and explain why harsh mouthwashes can cause lasting damage to the oral microbiome. They also discuss heavy metal corrosion in saliva, the release of the inflammatory cytokine RANTES in immunologically stressed areas of the jaw, and the biological benefits of metal-free, tissue-level ceramic implants as a tissue-friendly protective barrier.

Biohack: After brushing your teeth in the morning, gently swish a spoonful of unrefined coconut oil around your mouth for three to four minutes—a practice known as oil pulling—then spit it into the trash to gently reduce the bacterial load, neutralize pH, and keep the oral microbiome balanced without harsh chemicals.

Following the latest episodes, Mario and Max received a wide range of detailed questions from the community. In this Q&A episode, the two doctors tackle common myths and clarify the medical facts behind frequently confused lab markers, dietary approaches, and supplements.

Mario and Max explore how maltodextrin works in combination with fructose during exercise and compare heme iron from unprocessed meat with plant-based iron sources. When it comes to elevated homocysteine levels, they explain why statins do not address the problem, how methylated B vitamins and betaine (TMG) can help, and why proper laboratory sample handling is essential. They also discuss the reported 840-fold increase in infection risk associated with raw milk products, the evidence on lithium orotate for dementia, and the actual risk of atrial fibrillation associated with omega-3 supplementation.

Anna Kraft was a successful sports journalist and former elite sprinter in the prime of her life when a multiple sclerosis diagnosis suddenly changed everything in her early thirties. Rather than passively accepting the chronic condition, she learned to listen to her body again. In this episode, she speaks openly about how she actively manages chronic fatigue.

Together with Anna Kraft, Mario and Max explore strategies for improving quality of life beyond medication alone. They examine the biochemical effects of consistently avoiding sugar and gluten on the gut, taste perception, and energy levels. The two doctors also assess the medical risks of uncontrolled supplementation—including kidney complications from vitamin D and nerve damage from vitamin B6—evaluate HRV measurements as an indicator of stress resilience, and explain why strength training and protein are essential pillars of longevity.

Finally, Anna shares her personal biohack: a one-minute ice-cold shower in the morning, combined with deliberate counting and focused breathing, to prepare her body for the day and sharpen her mental focus.

Whether during everyday activities, exercise, or sleep, many people unconsciously breathe through their mouths. What is often dismissed as a harmless habit or a consequence of mild allergies can deprive the body of an important mechanism for optimal oxygen delivery.

In this episode, Mario and Max examine the anatomical and physiological benefits of nasal breathing. They explain how nitric oxide (NO), produced in the nose, dilates blood vessels in the lungs to improve blood oxygen saturation—and why humming while exhaling can increase NO production severalfold. They also explore the causes of swollen nasal turbinates, including colds, allergies, and alcohol, and compare tools such as nasal strips, mouth taping, and nasal rinses.

Finally, they share their practical biohack: position a nasal strip correctly across the cartilaginous part of the nose or use a saline nasal rinse in the evening to open the airways before sleep and wake up feeling more refreshed.

Taking a warm shower or going to the sauna before bed may sound counterintuitive—after all, the body needs a drop in core temperature for restorative sleep. What is often overlooked, however, is that this deliberate heating is precisely what initiates the subsequent cooling process.

In this episode, Mario and Max explore the science of thermoregulation. They explain how warm water at 38 to 43°C dilates the peripheral blood vessels in the hands and feet, allowing the body to release excess heat more efficiently. They also compare warm showers, traditional saunas, infrared saunas, and baths—and warn against excessive heat exposure immediately before bedtime.

Finally, Mario and Max share their personal experiences and practical biohack: schedule a 10- to 15-minute warm shower or bath around one to two hours before bed. This gives the blood vessels enough time to release heat and can noticeably improve sleep efficiency.

When we experience overstimulation or acute stress, the body automatically turns to a natural protective mechanism: the physiological sigh. Rather than leaving this reflex to chance, cyclic sighing can be used as a deliberate tool to calm the nervous system within seconds.

In this episode, Mario and Max examine the physiological processes behind the method. They explain how a double inhale reinflates collapsed alveoli, improves gas exchange, and how the prolonged exhale stimulates the vagus nerve via the baroreceptor reflex. They also compare the technique with box breathing and explain why controlled breathing is one of the fastest ways to activate the parasympathetic nervous system.

Finally, they share a practical biohack for everyday life: five rounds of double inhales before a stressful appointment or after work can be enough to noticeably calm the body and relieve mental tension.

In the biohacking community, drinking coffee immediately after waking is often considered a mistake that disrupts cortisol levels and causes an afternoon crash. But how well does this theory actually hold up in clinical practice?

In this episode, Mario and Max explore the mechanisms of adenosine receptors and so-called cortisol stacking. They explain how the body adapts to consistent routines and why the scientific evidence is surprisingly relaxed about the supposed morning restriction. Instead, they focus on the factor that matters most for recovery: caffeine’s average clearance time, which calls for a clear cut-off around nine hours before bedtime.

Finally, they share their own everyday strategies and practical biohack: a two-week experiment to identify your individual caffeine window and use a wearable to measure its effects on your sleep efficiency.

Typical indoor environments provide just 200 to 500 lux—far too little to signal to the brain that it’s time to start the day. Cortisol is also often mistakenly viewed purely as a stress hormone, even though a targeted morning increase is essential for alertness, energy, and focus.

In this episode, Mario and Max explain how circadian light timing works and explore the cortisol awakening response, which begins at around 800 lux. They discuss why even an overcast sky is more effective than standard indoor lighting and how color temperature, measured in Kelvin, influences the body’s circadian rhythm. They also compare daylight lamps, smart-home systems, and sunrise alarm clocks for the darker months of the year.

Finally, they share their personal routines and reveal their practical biohack: how just a few minutes on the balcony or by an open window can set the body’s biological clock and noticeably improve sleep efficiency the following night.

Ice baths, cold showers, and cold chambers are often touted as a quick fix for boosting the immune system and metabolism. But does cold really burn calories in a noticeable way, or is this effect based on a misconception?

In this episode, Mario and Max analyze the scientific evidence behind cold therapy. They explain the medical aspects of norepinephrine release and its effect on stress resilience, and compare cold showers, ice baths, and cold chambers. They also show how box breathing breaks the fight-or-flight response in cold water and explain what’s behind the study showing a 29% reduction in sick leave.

Finally, the two share their own routines and offer a practical tip for getting started easily in your own bathroom.
