The Dr. Hyman Show

What’s Really Driving Infertility—and What You Can Do About It
Fertility struggles are far more common than most people realize—and far more complex than we’re often told. Today I answer listener-submitted questions on fertility, hormone balance, and preparing your body for conception.

Here’s what I cover:
• Why infertility is rising and what’s really driving it
• The hidden role of blood sugar, inflammation, and toxins in hormone balance
• What to do if labs are “normal” but fertility struggles persist
• How lifestyle and nutrition improve egg and sperm quality
• Simple, practical steps to support fertility now and long-term

Fertility challenges are complex and often influenced by underlying imbalances. Addressing root causes can help support your body’s natural resilience over time.

On this episode of The Dr. Hyman Show, I sit down with Dr. Robert Hedaya, a psychiatrist who has spent decades working at the intersection of biology, brain function, and mental health. His approach starts with a different question than most psychiatry asks: what’s interfering with the brain’s ability to regulate, adapt, and repair itself?

We talk about why many mental health diagnoses describe symptoms without explaining causes—and how measuring brain function, energy, and network activity is opening the door to more precise, individualized care.

Watch the full conversation on YouTube or listen wherever you get your podcasts.

We discuss:

• How biological imbalances can drive anxiety, depression, and cognitive symptoms

• Why many “treatment-resistant” mental health issues have overlooked root causes

• How brain energy and mitochondrial function influence mood and cognition

• What advanced brain mapping reveals about how your brain is actually working

For far too long, mental health care has focused on managing symptoms in isolation. This discussion looks at what becomes possible when we treat the brain as part of the whole system and support its ability to heal.

In this Office Hours episode, I break down what the government finally got right about food, where the new guidelines still fall short, and—most importantly—how to apply them in real life without confusion or overwhelm. For the first time in decades, there’s meaningful progress: a recognition that ultra-processed foods are harming us, that protein matters for optimal health, and that nutrition isn’t one-size-fits-all. But there’s still work to do.

In this episode, I break down:
• Why calling out ultra-processed foods is the most important—and historic—shift in the new guidelines
• What the new protein recommendations actually mean for everyday people
• Why the low-fat era is finally ending—and why whole foods matter more than isolated nutrients
• Where the guidelines still fall short, including saturated fat limits, whole grain recommendations, and lack of personalization
• How to apply the guidelines to kids and families without perfection or overwhelm
• Why chronic disease is a policy problem—not a personal failure

The new dietary guidelines are a foundation, not a finish line. Use them as a starting point: focus on food quality, reduce ultra-processed foods, prioritize protein, and personalize your choices based on how your body responds.

Longevity isn’t just about what you eat or how you train—it’s really more about whether you believe your body is worth investing in.

On this episode of The Dr. Hyman Show, I’m joined by my longtime friend and colleague Dr. Gabrielle Lyon to explore why muscle may be one of the most overlooked drivers of long-term health. We focus on practical, accessible ways to build strength as you age, and why muscle plays a much bigger role in your health than most people realize.

We explore:

• How strength training supports your blood sugar and metabolic health, beyond what the scale can show

• Why muscle quality—not weight—is a stronger predictor of long-term health

• How building strength helps you stay mobile, capable, and resilient as you age

• What most people miss about protein and muscle health

Aging well is something you can actively support, starting with how you care for your body today. And strength is one of the most powerful places you can begin.

What Should I Actually Eat?
Diet confusion is everywhere. But the truth is, there’s no one-size-fits-all diet. The best diet is the one that works for your biology. In this Office Hours episode, I answer your most common diet questions and break down the core principles everyone should understand before choosing how to eat.

In this episode I break down:
• Why the “best diet” is personalized—and why ideology should never override biology
• The universal principles everyone should follow, regardless of diet
• Why ultra-processed foods—not carbs, fat, or protein—are the real problem
• How blood sugar dysregulation drives chronic disease, including mental health issues
• Keto, paleo, vegan, and Mediterranean: who they help, common mistakes, and what to watch for
• How to tell if your diet is working—using symptoms, energy, digestion, mood, and labs

Your body is the smartest doctor in the room. The key is learning how to listen.
