No Filter Doctor

Most of us think about oral health in terms of cavities, gum disease, and keeping our teeth clean. But what happens in our mouths may have implications far beyond our teeth and gums.

In this episode of No Filter Doctor, I'm joined by Dr. Ekta Sem, a dentist specializing in comprehensive integrative dentistry, to explore the connection between oral health and systemic disease.

We discuss the relationships between periodontal disease, diabetes, cardiovascular health, inflammation, and sleep-disordered breathing. We also get into practical oral hygiene, including flossing, tongue scraping, mouthwash, and oil pulling.

I learned quite a bit during this conversation, and some of it genuinely surprised me.

What if we could take a snapshot of what is happening inside our bodies at the molecular level? Could that information help us detect diseases earlier, understand why people respond differently to treatments, or even personalize nutrition?

That is what researchers are exploring through metabolomics, an emerging field of medicine studying the small molecules involved in our body's biochemical processes.

In this episode of No Filter Doctor, I explain what metabolomics is, how it differs from genomics, and where the research is taking us. From newborn screening to cancer detection and precision nutrition, the possibilities are exciting, but there is still plenty we don't know.

And as with any emerging science, there is a difference between legitimate medical research and the promises the wellness industry may try to sell us.

We plan for our financial future. Why don’t we plan for our future health the same way?

In this episode of No Filter Doctor, I introduce what I call health spanning: starting with what we want to be able to do decades from now, measuring where we are today, and building a deliberate plan to improve the odds of getting there. That might mean maintaining the fitness to hike with our grandchildren, the strength to live independently, or the physical and cognitive capacity to travel in retirement. Pasted text

I also explain why health spanning is different from preventive care, sick care, and biohacking, and why I think this is a missing piece in healthcare.

When we talk about health, we tend to focus on the things we can measure: blood pressure, cholesterol, body composition, fitness, and lab results. But some important parts of our health do not show up on a blood test.

In this episode of No Filter Doctor, I take a look at three of them: social connection, belonging, and play. We get into the evidence linking social relationships with physical health, mental health, cognition, and even mortality. But we also go beyond the data to talk about the difference between being around people and actually belonging, why adults still need to play, and what these less measurable parts of health can look like in real life.

This one gets a little more personal than most.

The United States is extraordinarily good at treating illness. But how did we end up with a healthcare system that is much better structured to pay for sickness than to plan for long term health?

In this episode of No Filter Doctor, I trace the history of American healthcare from the first hospital insurance plans through employer sponsored insurance, Medicare and Medicaid, managed care, the Affordable Care Act, PBMs, prior authorization, and the corporate consolidation of healthcare.

There is no single villain in this story. Instead, it is a series of attempts to solve legitimate problems that repeatedly created new ones. And that history helps explain the system we have today.

The skin care industry is filled with creams, serums, and active ingredients promising younger-looking skin. But which topical ingredients actually have evidence behind them?

In this episode of No Filter Doctor, I break down the science behind topical skin care for aging skin. We look at retinoids, vitamin C, niacinamide, alpha hydroxy acids, hyaluronic acid, collagen, peptides, antioxidants, estrogen, and more.

We also discuss something that marketing often leaves out: whether these molecules can actually penetrate the skin deeply enough to produce the effects being advertised.

The evidence is much stronger for some ingredients than others. This episode will help you understand what the research supports and what may not be worth your money.

Testosterone therapy in men is everywhere right now, but the conversation is far more nuanced than simply checking a testosterone level and writing a prescription.

In this episode of No Filter Doctor, I’m joined by board-certified urologist Dr. Amy Brode for an in-depth discussion about low testosterone and testosterone therapy in men.

We discuss what “low testosterone” actually means, symptoms and testing, reversible causes, who may benefit from treatment, fertility, different treatment options, and when testosterone should be avoided. We also dig into the TRAVERSE trial and what newer evidence tells us about cardiovascular and prostate cancer risk.

And, of course, we bust some testosterone myths along the way.

Vaccines are often discussed as though they are either completely safe or inherently dangerous. Neither is an accurate way to evaluate a medical intervention.

In this episode of No Filter Doctor, I take a data-driven look at vaccine safety using influenza and measles as examples. We compare the risks associated with vaccination with the risks of the diseases themselves, examine the history behind the MMR and autism controversy, and address several common vaccine claims circulating online.

This is not about telling you what decision to make. It is about understanding the actual evidence so you can make an informed one.

You are eating well. You exercise. You have not dramatically changed your habits. So why is your body suddenly changing in midlife?

In this episode of No Filter Doctor, I explain why the same diet and exercise routine that worked in your 20s and 30s may stop working after 40, particularly for women.

We discuss how aging, declining estrogen, loss of muscle mass, changes in metabolism, visceral fat, sleep, and insulin resistance converge during midlife. More importantly, we talk about what needs to change, including progressive resistance training, cardiovascular exercise, protein, fiber, sleep, and when it may be time to consider medical causes or treatments.

Midlife weight gain is real. The answer is not simply to eat less and exercise more. It is to adapt what you are doing to the body you have now.

Knowing what you want to change is often easier than figuring out how to actually make it happen.

In this episode of No Filter Doctor, I walk through the process of making meaningful, sustainable changes in your life. We start with creating time and deciding what actually matters to you, then move into setting specific goals and assessing your readiness for change.

I also explain how the Kaizen approach of small, consistent changes can be applied to nutrition, exercise, and other health goals, along with practical strategies that can help those changes last.

The goal is not to overhaul your life overnight. It is to create the space for change, start small, and build from there.
