Does regular sexual intimacy actually help couples stay together long-term? In this episode of The Longevity Protocol, we break down the research behind one of the most important—and most overlooked—predictors of relationship stability: sexual satisfaction.

Multiple studies show that sexual satisfaction is strongly associated with overall relationship satisfaction, emotional bonding, and long-term commitment. In fact, couples with high sexual satisfaction report significantly higher relationship satisfaction, while sexual dissatisfaction has been linked to a markedly increased risk of separation and divorce—especially when one partner is satisfied and the other is not.

But this episode goes deeper than the surface-level “frequency” conversation. We explore what relationship science actually emphasizes: that quality and mutual satisfaction matter far more than raw numbers. Even moderate frequency can be sustaining if both partners feel emotionally connected, valued, and aligned. On the other hand, frequent sex can still be damaging if it’s pressured, distressing, or rooted in resentment.

We also discuss the physiological mechanisms that may explain why sexual intimacy supports relationship longevity, including the release of bonding hormones like oxytocin and stress-reducing endorphins, along with the powerful feedback loop between intimacy, communication, and emotional closeness.

In this episode, you’ll learn:

• Why sexual satisfaction is one of the strongest predictors of relationship stability

• How sexual dissatisfaction increases divorce risk

• Why emotional intimacy explains much of the “sex + stability” connection

• Why quality matters more than frequency

• How communication drives both intimacy and long-term commitment

• The biology behind bonding and attachment

This is a science-based conversation about sex, connection, and what keeps couples together—not just emotionally, but physiologically.

In this episode, we step into a difficult but necessary conversation.Recent headlines surrounding Dr. Peter Attia and the release of new Epstein-related files have sparked intense reactions across social media — particularly from members of the medical community. But this episode is not about accusations, speculation, or personal scandal.It’s about something deeper.It’s about how quickly public figures are elevated, dismantled, and used as vehicles to attack broader ideas. It’s about whether controversy surrounding one individual should invalidate an entire field of medicine. And it’s about what happens when media reaction begins to erode trust in preventive health, lifestyle medicine, and longevity-focused care.We discuss:The difference between personal controversy and professional contributionWhy longevity medicine is being labeled a “marketing term” — and why that argument falls shortHow media cycles can be used to discredit movements, not just individualsThe psychological tendency to idolize and then destroy public figures

Why lifestyle, prevention, and health freedom conversations matter now more than everThis is not a defense of any individual.It is a defense of thoughtful medicine.It is a call for restraint in reaction.And it is a reminder that emotional instinct is not the same as reasoned response.As always, our goal is clarity, not chaos.Listen with discernment. Think independently. Stay measured.

What if one of the most powerful longevity tools isn’t a supplement… but your sex life? In this episode of The Longevity Protocol, Dr. John Robinson breaks down the real epidemiological research showing that regular sexual activity is strongly associated with lower mortality risk, improved cardiovascular outcomes, stronger immune function, and better long-term hormonal health—for both men and women.

This isn’t pop psychology. It’s long-term population data. Studies like the Caerphilly Cohort Study (tracking over 1,000 men for 10 years) found that men with higher sexual frequency had roughly a 50% lower risk of death compared to those with very low activity. Similar findings appear in Swedish and Irish longitudinal studies, as well as large female-focused research like the Women’s Health Initiative (WHI), which followed over 93,000 women and found that sexually active women had a 36% lower risk of cardiovascular mortality, even after adjusting for lifestyle and health factors.

Dr. Robinson also explains the deeper biological mechanisms behind these outcomes—how sexual activity impacts oxytocin, testosterone, estrogen signaling, DHEA, inflammation markers like CRP and IL-6, and even immune defenses like IgA production. Beyond physiology, the episode explores how intimacy reduces chronic stress, improves sleep, strengthens relationships, and supports nervous system regulation—key drivers of healthspan and lifespan.

This episode also covers practical insights on frequency, age-related changes, male vs. female benefits, solo vs. partnered activity, and why sexual health is not separate from overall health—it’s a direct reflection of it. Dr. Robinson also discusses the research showing that men may benefit from weekly orgasms, and why 21 ejaculations per month has been linked to a significantly lower risk of prostate cancer.

If you want to understand the science behind why intimacy is tied to longevity—and how to protect this part of your health as you age—this episode is a must-listen.

🔥 Most People Are Eating Protein Wrong — Here’s How to Fix It

If you want to build muscle, boost metabolism, balance hormones, and age with strength, your diet must start with protein done correctly.

In Episode 38 of The Longevity Protocol Podcast, Dr. John Robinson and Dr. Cristina Bosch break down the real science behind optimal protein intake for muscle growth and longevity — not the outdated RDA numbers created in the early 1900s.

This episode is your blueprint for eating in a way that supports maximal muscle growth, metabolic stability, and healthy aging.

Why the optimal range is 0.25g per pound of bodyweight — and why eating under 20g or over 50g can reduce muscle protein synthesis.

Most people need 0.7–1.0g per pound of body weight daily.

New research shows total daily intake matters most — not timing.

🥚 Eggs
🥛 Dairy
🥩 Beef
🐓 Chicken
🐖 Pork
💥 And why vegan protein sources often fail digestive and anabolic needs.

Carb-heavy food culture, misinformation, and decades of anti-meat propaganda.

Ancestral nutrition, nose-to-tail eating, and why traditional diets were naturally protein-dense.

• Better glucose control
• Lower inflammation
• More myokine signaling
• Stronger bones
• Improved stress resilience
• Better mobility as you age

Dr. Robinson & Dr. Bosch share their exact evidence-based stack:
• Micronized Beef Protein
• YOLKED (Fortetropin)
• Creatine (10g/day)
• Leucine (2.5–5g/day)

03:45 – How much protein per meal
07:20 – Daily protein requirements
10:55 – Protein timing myths

In this episode of The Longevity Protocol, we’re diving into the top 3 things that truly support muscle building. We’ll cover one hormone, one supplement, and one peptide stack—and explain how each plays a role in performance, recovery, and long-term health.

Here’s what we’ll discuss:

• Testosterone & Nandrolone: Why hormone optimization matters for muscle, energy, and mood.

• Creatine: The most studied supplement in the world—and why it still works.

• CJC + Ipamorelin: How this peptide combo helps stimulate natural growth hormone for recovery and lean mass.

• BONUS: A look at regenerative therapies like stem cells for muscle and joint health.

We’ll also bust a few myths along the way:

• “Creatine is a steroid” → It’s not.

• “Hormone therapy is only for aging men” → It’s about function, not just age.

• “You need extreme training to build muscle” → Smarter strategies make the difference.

If you want to maximize your training, protect your recovery, and understand the science of muscle growth, this episode will give you the tools you need.

• Why long-term couples don’t resolve every conflict

• The power of letting go (not suppressing)

• How emotional recovery builds resilience

• Why choosing peace matters more than being right
