Extend Podcast with Darshan Shah, MD

Hormones influence far more than reproductive health. They affect your sleep, mood, metabolism, muscle, bone health, brain function, stress response, and how you age—yet hormone health is still often reduced to a handful of numbers on a standard blood test.
In this episode, I'm joined by Dr. Pamela Smith, a physician who has spent decades practicing and teaching personalized medicine, to break down what women and men need to understand about hormone replacement therapy, healthy aging, and disease prevention.
We explore estrogen, progesterone, testosterone, DHEA, cortisol, thyroid hormones, insulin, and one hormone many people have never even heard of: pregnenolone. More importantly, we discuss why hormone optimization should never be one-size-fits-all.
Dr. Smith explains why two people of the same age may need completely different approaches, why testing before treatment matters, and how hormones interact with everything from gut health and methylation to toxins, blood sugar, bone health, and cancer risk.
In this episode, you'll learn:
Why hormone replacement therapy should be personalized to the individual
The roles of estrogen, progesterone, testosterone, DHEA, cortisol, thyroid, and pregnenolone
What women should understand about hormones and breast cancer risk
Why hormone metabolites and methylation may matter
How gut health and environmental toxins can influence hormone health
Why fasting insulin can reveal metabolic dysfunction before diabetes develops
How stress and cortisol affect blood sugar, cholesterol, blood pressure, and bone health
Why genetic and advanced testing are changing personalized and preventative medicine
We also discuss PCOS, menopause, micronutrients, glutathione, environmental toxins, therapeutic plasma exchange, genetic cancer screening, exercise, and the emerging tools that may help us identify disease risk earlier.
The biggest takeaway from this conversation is simple: optimal health isn't about giving everyone the same protocol. It's about understanding your individual biology, measuring what matters, and intervening before dysfunction becomes disease.

What if your gut health is the missing piece behing your hormones, energy, metabolism, and how you feel every day?
Today, I sit down with Dr. Cassie Smith, a double board-certiied endocrinologist and internal medicine physician who has taken a deeper look at the connection between gut health, hormones, thryoid function, metabolism, and overall health.
We talk about why "normal" lab results don't always mean optimal health, how gut health can influence hormone metabolism, the role of stress and inflammation and why understanding your individual biology matters when it comes to feeling your best. 
In this episode, we learn:
The connection between gut health and hormones
Why gut health matters for thyroid and metabolic health
The differnce between "normal" and optimal hormone levels
How stress can affect the gut, hormones, and inflammation
What women should know about hormones during perimenopause and menopause
The role of fiber, nutrition, and daily habits in gut health

Most people know they should eat more fiber. But what we're learning about fiber, gut health, and the microbiome goes far beyond digestion.
Your gut contains trillions of microbes that depend on what you eat—and different types of fiber feed different bacteria. Those microbes can influence everything from blood sugar regulation and metabolic health to cholesterol and the way your digestive system functions. That means it's not just about getting more fiber. The diversity of the fiber you eat matters, too.
In this episode, I'm joined by Colleen Cutcliffe, PhD, microbiome scientist and co-founder and CEO of Pendulum Therapeutics, to break down what the latest science tells us about fiber and the gut microbiome.
Colleen explains the difference between soluble and insoluble fiber, why most people aren't getting enough, and how fiber and prebiotics support beneficial gut bacteria. We also explore how the microbiome changes throughout life, the role of polyphenols, and the emerging connection between specific gut bacteria and metabolic health.
In this episode, you'll learn:
• Why fiber is one of the most important foods for your gut microbiome
• The difference between soluble and insoluble fiber—and why you need both
• Why fiber diversity may be just as important as total fiber intake
• How the gut microbiome is connected to blood sugar and metabolic health
• How certain types of fiber can support healthy LDL cholesterol levels
• The difference between fiber, prebiotics, probiotics, and polyphenols
• Practical ways to increase the amount and diversity of fiber in your diet
We also discuss why getting enough fiber can be harder than it sounds, how gut health needs can differ between children and adults, and where targeted microbiome products like Pendulum's Gut Fuel may fit alongside a fiber-rich diet.
The microbiome is changing the way we think about nutrition. And one of the simplest places to start supporting it may already be sitting on your plate: eat more plants, eat more types of fiber, and feed the microbes you want to thrive.
