Summary

On this episode of The Dr. Hyman Show, we’re exploring the emerging science of metabolic psychiatry. My guest, Dr. Iain Campbell, is a researcher at the University of Edinburgh and someone who has lived with bipolar disorder himself. He brings a rare dual perspective as both a scientist and a patient to this critical conversation.  Together, we discuss what’s really driving psychiatric conditions like bipolar disorder and why a systems-based approach may hold the key to meaningful recovery. Catch our full conversation on YouTube here - https://youtu.be/YCcZb2H2Ceg We unpack: • What it means when mental health symptoms start in the body—not just the brain • How to tell if metabolism, sleep, or inflammation are driving your mood swings • Why seasonal changes impact energy and mood, and how you can stay steady year-round • When keto might help where meds haven’t, and what to know before trying it • How to catch metabolic red flags before they affect your mental health When we shift how we see mental health, real healing becomes possible. There are answers, and this episode can help you find them.

Dr. E. A. N. Campbell is a neuroscientist and researcher exploring the radical idea that bipolar disorder might begin not in the brain but in the body. I didn't realize it was a kind of form of ketogenic diet. Essentially, that's what it is. I felt like I'm thinking clearly about my life for the first time. I'm not depressed. I'm not manic. If your brain can change like that and it changes who you are as a person, what does this mean about who we are? Are we just a bunch of chemicals that if they're disrupted, you become a different person?

You know that I am a big believer in food as medicine and organ meats are some of the most nutrient-dense foods on the planet. They're often called nature's multivitamin for a reason. Organs like liver, heart, and kidney are packed with B vitamins for energy, vitamin A for immune and skin health. Plus bioavailable minerals like iron, zinc, and selenium. The problem,
