Apr 6, 2026 · Healthy AgingThe Power of Mitochondria: Energy, Aging, and the Science of Staying Vital
Mitochondria live inside nearly every cell in your body, and they perform one of the most important jobs there is. They convert the nutrients in the food you eat and the oxygen you breathe into usable energy. If your mitochondria aren’t well supported, energy production may start to slide. In fact, researchers now believe that mitochondrial health plays a significant role in how we age. Current thinking is that how well you care for these microscopic energy factories may, to a significant extent, determine whether you stay vibrant and energized with the passing of the years or start feeling like an elder long before your time.

Mar 30, 2026 · Healthy AgingMore Than Muscle: Creatine Fuels Brain Power and Healthy Aging
We all know about creatine, the stuff that body builders and gym rats buy in tubs to help pump up their physiques. But it isn’t only muscles that need energy. Your brain has to do a lot of thinking, that and overseeing virtually every process in your body, all of which requires a generous fuel supply. Researchers are beginning to uncover gains in cognitive sharpness, memory, even protection against dreaded neurodegenerative diseases like Alzheimer’s. And that makes creatine a potentially very powerful longevity enhancer. Given that creatine levels decline with age, I now recommend it to my middle-aged and older patients, in measured and monitored doses.

Mar 23, 2026 · Healthy Aging7 “Healthy” Habits That Can Age You Far Too Fast
When I started my practice decades ago, a big part of it was educating patients on the health basics. Fast forward a few decades and the tide has turned, thanks in large measure to the wealth of information available on the internet. Patients now arrive with a much better baseline understanding of health and how to influence it. Which is great except that too much information can mislead almost as often as enlighten, and myths are often taken as gospel. When these ideas get over-simplified or just plain misunderstood, you can wind up accelerating the very processes that drive biological aging.

Mar 16, 2026 · Healthy Aging14 Ways to Maintain a Youthful Brain – by Curbing Chronic Inflammation
While there are many factors believed to contribute to diseases like Alzheimer’s, Parkinson’s and various forms of dementia, one biological common thread that keeps showing up across countless studies is chronic inflammation, often also referred to as “inflammaging.” One of the organs that’s particularly sensitive to easily damaged by years of unchecked chronic inflammation? It’s your brain. But the good news is that chronic inflammation is heavily influenced by the choices we make every day, and when done right, you can shift your brain health in a positive direction for decades to come – so the time to start is now.
Mar 13, 2026 · NutritionWhy You Must Understand Hunger, Not Calories
The weight loss advice to just ‘Eat Less’ is based on the flawed premise that weight gain results from ‘overeating’. This represents the deadly sin of gluttony which ultimately represents a personal choice. You choose both what and how much to eat. Therefore, you can simply choose to eat less, and that will cure the obesity problem.

Mar 9, 2026 · Health & WellnessThe Big Power of Small Doses: Optimizing Health with My Microdosing Top 5
“Less is more.” That’s hardly the usual refrain of conventional Western medicine, which likes to prescribe powerful pharma drugs at relatively large doses to knock out symptoms. Unwelcome side effects are tolerated (by the doctor anyway) if they seem manageable. Well, in the past few years, however, a whole new, and smaller, world has opened up, one prescribing (mostly) prescription drugs at either “microdose” or much smaller than full-strength levels, not to treat full-blown disease, but to gently nudge key biological systems in a healthful direction.

Mar 2, 2026 · NutritionHow Intermittent Fasting Promotes Your Hormonal Health -- and Why I’m A Fan!
When hormones stop playing nicely with one another, blood sugar swings, sleep becomes lighter or harder to come by, cravings feel louder, weight can shift in ways that feel unfair, and stress tends to linger. Over time, these disruptions can add up, affecting mood, metabolism, immune health, resilience, and even how quickly we age. The good news is that hormones are remarkably responsive to everyday choices – and fasting is a fantastic way to help smooth out the hormonal ride.

Feb 23, 2026 · Healthy Aging10 Ways Exercise Rewires, Slows — and Even Reverses Aging
Most of us were raised to believe you get older, your genes blow the whistle, your body ‘breaks.’ Fortunately for us, modern biology has been quietly rewriting that story and the new version is a lot more hopeful. Over the last few decades, researchers have mapped out a set of common biochemical changes which, over time, tend to push us in the direction of disease and frailty. These subtle shifts, known collectively as the ‘hallmarks of aging.’ The good news is that most, quite possibly all, of these hallmarks respond positively to healthy lifestyle habits. If a long, healthy life is what you’re shooting for, one of the hands-down most powerful habits you can cultivate is movement.

Most people outside the medical or research world probably aren’t familiar with AMP-activated protein kinase, or AMPK.

Think of it this way: AMPK sets the table for long-term metabolic health and healthy aging.
