The Dr. Hyman Show

If we want to fix food, we have to fix the institutions shaping what our kids eat every day.

Public schools are effectively the largest restaurant chain in America, serving 30 million children. For many of them, school meals account for half of their daily calories. And yet, a majority of those calories still come from ultra-processed food.

On this episode of The Dr. Hyman Show, I sit down with Nora LaTorre, CEO of Eat Real, to talk about why the school cafeteria may be the most powerful lever we have to reverse the childhood health crisis—and why change is already happening faster than most people think. Watch the full conversation on YouTube or listen wherever you get your podcasts.

Today we discuss:

• Why school food policy affects your family—even if you pack lunch

• How removing added sugar from school menus can change focus, behavior, and long-term health

• Why school lunch participation rises when districts upgrade to real food

• How changing school procurement reshapes local farms and food systems

• What you can do as a parent to influence your district

In less than two years, schools are proving that real food can scale across red states, blue states, rural communities, and major cities. When procurement changes, farms change, and when menus change, our children have a better chance to thrive.

For years, we’ve been told that overeating is a problem of willpower, and if we just tried harder, we’d eat less and feel better. But the science tells a very different story. In today’s Office Hours, I reframe the conversation around cravings and overeating—replacing shame and self-blame with science, clarity, and practical solutions.

In this episode I share:
• Why food addiction is driven by brain chemistry, not lack of discipline
• How ultra-processed foods are designed to override satiety and keep you craving more
• What the “bliss point” is and how Big Food engineers addictive foods on purpose
• The link between hyperpalatable foods, chronic disease, and the healthcare crisis
• Practical steps to reset your brain, reduce cravings, and break free

When you understand how modern food is designed to override your biology, everything changes. You stop blaming yourself and start reclaiming your health with real, nourishing food and the right support.

Too often, we focus on treating symptoms without fully understanding the systems underneath them—or the conditions that allow the body to function well in the first place.

On this episode of The Dr. Hyman Show, I sit down with Fidji Simo, CEO of Applications at OpenAI, to explore how AI could help us shift medicine from treating symptoms to restoring systems. We talk about why chronic illness is so often misunderstood, how health data has been fragmented across silos, and what becomes possible when we finally see the full picture. Watch the full conversation on YouTube or listen wherever you get your podcasts.

In this episode, you’ll learn:

• Why having a diagnosis doesn’t always explain what’s actually driving your symptoms

• How connecting your labs, lifestyle data, and health history can reveal patterns you might otherwise miss

• What it looks like to move from reactive care to proactive, personalized health

• How better context can help you make clearer decisions about food, sleep, movement, and recovery

Health isn’t built in a doctor’s office. When you create the right environment, the body often knows what to do—and understanding your own biology is one of the most powerful steps you can take toward creating health, not just reacting to disease.

For decades, we’ve been told that high cholesterol is the main driver of heart disease—and that lowering LDL should be the primary goal. But as science has evolved, so has my thinking. In today’s Office Hours, I explain why cholesterol alone doesn’t tell the full story, what most doctors still aren’t testing, and what’s really driving heart disease for the majority of people.

Today we discuss:
• Why many people have heart attacks despite “normal” LDL cholesterol
• The difference between cholesterol levels and cholesterol particles
• How inflammation and insulin resistance fuel heart disease
• Why sugar and refined starches are more dangerous than fat
• The most important labs to assess real cardiovascular risk
• What ApoB, lipoprotein(a), and triglyceride-to-HDL ratio reveal about your health
• How metabolic dysfunction—not cholesterol alone—drives plaque buildup

Heart disease is far more complex than a single lab value. When you understand the role of metabolic health, inflammation, and the right biomarkers, you can take meaningful steps to protect your heart and long-term health.

Around the world, we’re seeing declining sperm counts, rising infertility, more erectile dysfunction, and lower testosterone—even in younger men.

These trends aren’t just affecting family planning; they’re pointing to something much bigger happening in men’s health.

Joining me today on The Dr. Hyman Show is Dr. Michael Eisenberg, a Stanford researcher and leading voice in male reproductive health. We talk about why sperm quality matters far beyond fertility—and how everyday health choices quietly shape it. Watch the full conversation on YouTube or listen wherever you get your podcasts.

[YOUTUBE THUMBNAIL]

We cover:

• Why sperm quality may be one of the strongest early indicators of overall health and longevity

• How metabolic dysfunction, belly fat, and low testosterone impact fertility and sexual function

• The role environmental toxins and endocrine disruptors play in declining sperm counts

• What men can do right now to protect fertility and long-term vitality

When we look at fertility through the lens of whole-body health, it changes how we think about prevention, risk, and longevity. Male fertility isn’t just about reproduction. It’s a signal.
