Why Mental Illness Is a Metabolic Problem—and What That Means for Your Health | Dr. Chris Palmer

Mark Hyman

Jan 7, 2026

Episode description

On this episode of The Dr. Hyman Show, I’m rejoined by psychiatrist and Harvard professor Dr. Chris Palmer for a conversation that challenges how we’ve been taught to think about mental illness.

For decades, psychiatry has focused on managing symptoms—often without asking what’s actually driving them. We discuss a different way of understanding mental health, one that looks beyond diagnostic labels and considers how whole-body biology influences brain function, resilience, and recovery.

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

In this conversation, we explore:

• Why mental illness is rising alongside obesity, diabetes, and other chronic diseases

• How whole-body biology influences mood, focus, and emotional resilience

• The link between inflammation, metabolic dysfunction, and conditions like depression and bipolar disorder

• How nutrition, testing, and lifestyle changes can support real recovery

If mental health has ever felt close to home for you or someone you care about, this conversation is meant to offer clarity, compassion, and a place to start.

This episode was recorded live at the Eudēmonia Summit, a conference exploring the future of health, longevity, and well-being. Learn more at eudemonia.net.

Understand metabolism as life’s essential process

The cessation of metabolism is the literal definition of death, and all lethal toxins, from cyanide to a Tylenol overdose, work by disrupting this fundamental process.

View psychiatric medications as temporary solutions, not long-term treatments

Psychiatric medications can be viewed as poisons, similar to chemotherapy, that can be life-saving in crises but are harmful when used long-term.
