Do you suffer with anxiety, depression, or another mental illness? Millions of people do. The usual treatment is a prescription medication. If that doesn’t work, the healthcare provider may offer a different one. Diet is certainly not the first topic on the provider’s mind. But what if, in addition to appropriate pharmacological treatment, you were able to nourish, protect and energize your brain with your diet? Our guest offers evidence that you can heal your mind with a ketogenic approach to eating.
We need to acknowledge that this approach is quite different from the plant-rich eating pattern advocated by last week’s guest, Dr. Will Bulsiewicz. Humans around the world have adopted a wide range of dietary regimens that support health. Listen to Dr. Georgia Ede explain why she thinks a paleo or ketogenic diet is helpful for bolstering brain health

Can You Heal Your Brain with Food?
We live in stressful times. More than 50 million Americans take prescription antidepressants, and millions more are on anti-anxiety medication. Unfortunately, while these drugs can be life savers, they don’t always work as well as we would like. In some cases, antidepressants are only about 10 percent more effective than a placebo
Dr. Georgia Ede is a psychiatrist who began her investigation into how food affects mental health serendipitously. She was experimenting with her own diet to address some physical health issues. She used a food and symptom journal to discover the best dietary choices for her own health. To her surprise, the “upside-down” diet that helped her feel better physically also improved her sleep and her ability to focus. She started looking into evidence that a paleo or ketogenic diet could benefit people with mental health challenges.
What Is Metabolic Psychiatry?
There is evidence that people consuming unhealthy diets full of fast food or ultra-processed products are more susceptible to symptoms of anxiety (Nutrition Neuroscience, May 19, 2026). On the other hand, people participating in a supervised weight-loss program using either a low-carbohydrate ketogenic diet or a low-fat diet reported improvements in mood (Obesity, Jan. 2007). Those on the ketogenic (Atkins) diet reported less hunger and fewer unpleasant symptoms
Researchers have also tested a ketogenic diet in people with schizophrenia or bipolar disorder (Psychiatry Research, May 2024). These volunteers also had metabolic disorders, including obesity, which is often an unwanted effect of the ant-psychotic drugs they take to treat their condition. This four-month pilot study saw participants lose weight, reduce insulin resistance and lower their triglycerides. Even more impressive, they had a 32 percent reduction in the Brief Psychiatric Rating Scale. They also reported better sleep and improved life satisfaction.
How Does Food Affect Our Brains?
Most of our body tissues are accustomed to getting energy from glucose, with the help of insulin. However, years of exposure to high levels of these compounds often makes the tissues less sensitive to the effects of insulin. The consequence is that the body–and therefore also the brain–is flooded with high levels of glucose. This exposure can result in the formation of advanced glycation end products in the brain, which can be harmful
The brain evolved to use either glucose or a flexible mix of glucose and ketones. These are the result of burning fat rather than sugar. A paleo diet will naturally provide more ketones and less glucose. Dr. Ede and colleagues have found that a ketogenic diet can be very helpful even for people with relatively serious mental problems. In one study (which was not placebo-controlled), patients hospitalized with severe persistent mental illness were given a ketogenic diet. Most did well and had significant improvements in their depression and psychosis symptoms (Frontiers in Psychiatry, July 6, 2022).
Is Ketosis Dangerous?
Ketosis itself simply means that you are burning fat as fuel rather than sugar. This can be achieved by following a diet that is high in animal fat, with moderate amounts of animal protein and low amounts of carbohydrate derived from plant foods. Ketosis is not inherently dangerous. However, Dr. Ede urges anyone who wants to heal their brain with diet to ask a healthcare provider to monitor and supervise the process. Prescription drug doses may require adjustment, and people may need support as they adopt a paleo or ketogenic diet. That is why this is not a do-it-yourself approach.
Is Coconut Oil Helpful to Heal Your Brain?
Dr. Ede described the benefits of medium-chain fatty acids produced in digesting fat. You may recall a video from a few years back in which a doctor described helping her husband recover from Alzheimer disease, at least partially, by giving him coconut oil. Some researchers consider Alzheimer disease to be a form of diabetes because the AD brain does not metabolize sugar effectively. Dr. Ede suggested that the benefits may be real, but getting medium-chain fatty acids from the diet rather than be taking coconut oil might be preferable. After Dr. Ede told us about Fran, who overcame significant memory problems by changing to a ketogenic diet, we hope there will be trials on this.
Future Trials on Diet to Heal Your Brain
Dietary trials are notoriously difficult to conduct. People often don’t stick to the prescribed diet, and it can be difficult to find an appropriate placebo for comparison. Nonetheless, Dr. Ede is looking forward to results from a large trial of the keto diet for people with schizophrenia or bipolar disorder. This study is being conducted in Australia
This Week’s Guest
Dr. Georgia Ede is a globally recognized expert in nutritional and metabolic psychiatry. Her 25+ years of clinical experience include 7 years at Harvard University, where she was the first psychiatrist to offer nutrition-based approaches to mental health conditions. Dr. Ede co-authored the first inpatient study of the ketogenic diet for serious mental illness, developed the first medically accredited course in ketogenic diets for mental health, and is a recipient of the Baszucki Metabolic Mind Award. Current research collaborations include pilot studies in pediatric bipolar disorder, adult ADHD, and PTSD. Her internationally bestselling book Change Your Diet, Change Your Mind: A Powerful Plan to Improve Mood, Overcome Anxiety, and Protect Memory for a Lifetime of Optimal Mental Health is being translated into 11 languages and is recommended by the New York Times Book Review.

Listen to the Podcast
The podcast of this program will be available Monday, August 24, 2026, after broadcast on Aug. 22. In this week’s podcast, we’ll learn how vegetarians can follow a ketogenic diet. How does the evidence Dr. Ede has collected accord with the chemical imbalance theory of mental illness? We also discuss why the standard American diet is not good for mental wellbeing, and we find out what might be in Dr. Ede’s own shopping cart. You can stream the show from this site and download the podcast for free.
