If I could tell my older readers (or younger readers who plan on becoming older readers) one thing to focus on for long-term health, longevity, and wellness, it would be to maintain your bone density. Not eat this food or do that exercise. Not get more sleep. Those are all important, and many of them fall under the rubric of and contribute to better bone density, but “maintain bone density” gets to the heart of aging. Even the importance of muscle strength shown in longevity studies of older people could actually indicate the importance of bone density, since bone density gains accompany muscle strength gains. You can’t gain muscle without gaining bone.
That’s because bones aren’t passive structures. They are organs that respond to stimulus and produce hormones and help regulate our metabolism.
Osteocalcin, a hormone produced by bone-building osteoblasts, communicates directly with fat cells to release a hormone that improves insulin sensitivity. The osteocalcin produced by bones plays a key role in testosterone production and male fertility, helps regulate mood and memory, and even interacts with the brains of developing fetuses. It may also help improve endurance, with studies in mice showing that older mice were able to run almost twice as far after being injected with osteocalcin.
Why do some people live well into their nineties with zero health problems, while others get sidelined by diabetes, heart disease, and autoimmune conditions? Sure, your genes play a role, but it’s your lifestyle that pulls the biggest lever. If you’ve followed the Primal Blueprint for more than a minute, you know it’s possible to reprogram your genes, regardless of what health struggles your parents or their parents faced. As a health coach, and someone who fully intends to become a centenarian one day, I’m fascinated by cultures who have their diet and lifestyle totally dialed in. Take the Blue Zones, for instance. These regions are spread throughout the world — but it’s not where they’re located that’s so important, it’s more about what the locals do on the daily that makes the biggest impact on their health. What’s Up with Blue Zones? Named by Dan Buettner, the National Geographic journalist who studied them, Blue Zones are five regions where people are known to live healthier and longer than anywhere else in the world, reaching the age of 100 at a significantly greater rate than most folks living in North America. Despite being scattered throughout the globe (the zones are in Greece, Italy, Japan, Costa Rica, and southern California), they share nine key lifestyle habits, including: Move naturally Have a clear sense of purpose Manage stress Eat ‘til you’re 80% full Consume a plant-based diet (stay with me here…) Drink in moderation Be part of a community Put family first Maintain a fulfilling social life I’m not saying you should drop your carnivore diet for one rich in grains and legumes, but you can’t argue with the fact that certain behavioural, societal, and environmental factors play a huge role in health and lifespan. Is It Genetics or Lifestyle? The study that fueled Buettner’s research was this one published in 1996, which evaluated 2872 pairs of Danish twins over a thirty-year period. Researchers looked at a variety of genetic and lifestyle influences and determined that only about 20% of how long you live is dictated by your genes, where the other 80% is all about lifestyle. Since then, more and more studies continue to roll out confirming his findings. Like this one that analyzed the DNA methylation levels of 318 men and women, ages 65-105, revealing that epigenetic control in aging had less to do with the participants’ chronological age and more to do with how they lived their life. Not only that, recent studies exposed the grim consequences of the COVID-19 pandemic, showing how factors including stress, isolation, and lacking purpose had a direct correlation to a decline in mental and physical health. According to research, loneliness shaves fifteen years off your life expectancy – roughly the same impact as being obese or smoking a pack of cigarettes a day. Since Buettner’s research has been out, several cities have adopted the Blue Zone principals and seen dramatic results. They’ve implemented these nine secrets of longevity to make it easier … Continue reading “What We Can Learn from World’s Longest Living Populations”
Read MoreMale menopause is a real thing, and the medical term for it is andropause. According to the Mayo Clinic, the term “Male Menopause” has been used to describe decreasing testosterone levels related to aging. See this article from Mark back in 2018.
One of the symptoms of male menopause can be erectile dysfunction (ED). Although for younger men, you can have ED without male menopause. ED can destroy a man’s confidence not just in the bedroom but in the larger picture of his life by causing depression, stress, moodiness and anger all things that peak performers do not want to associate with. But for men aged 35-64 these things can sneak up on us, fast.
We are all so busy “performing.” Being a Dad, a good husband, business owner, a hard worker, friend, trying to get your workouts squeezed into an already hectic week. In many cases, this usually leads to a pattern of not not getting enough sleep because of late night emails for work after having put the kids to bed, up early the next day to get right back at your hard charging life, with too little exercise and not enough Primal Nutrition. Which leaves you with high stress. Stress leads to high cortisol (more about cortisol below).
Maybe you had a little too much wine at dinner … it happens. Your wife or lover wants to “play” and so do you, but no response. Once, certainly is nothing to worry about but the definition of ED is “is the recurrent or persistent inability to attain and/or maintain an erection in order for satisfactory sexual performance.” So, what to do?
First, let’s look closer at the leading causes.

When it comes to slowing down the clock, life extension is indeed possible. The catch? There are two: it involves calorie restriction, and it has only been successfully demonstrated in lab animals. Studying longevity in humans is a bit more challenging. We don’t sleep in labs, we live a lot longer, and we like to eat. (Correction: we love to eat.) So while most of us would happily opt for a 40 percent increase on our life spans like food-deprived lab rats seem to achieve, we need a better route to get there.1
