Brief overview of the Ketogenic Diet
The Ketogenic Diet, commonly known as keto, is a low-carbohydrate, high-fat eating plan designed to induce a state of ketosis in the body. In this metabolic state, the body shifts from using glucose as its primary fuel source to burning fat, leading to various health benefits. The focus on fats and minimal carbs helps the body enter a state where it produces ketones, providing energy for both the brain and body. Beyond its renowned effectiveness for weight loss, the Ketogenic Diet has gained popularity for its potential cognitive and mental health benefits, making it a holistic approach to nourishing both the body and mind.
The traditional ketogenic diet is characterized by a strikingly high fat content, comprising approximately 90% of the total calories. However, variations of this diet have emerged, adjusting the fat intake and permitting greater proportions of protein along with slightly increased carbohydrate allowances.
Dedicated adherents of the ketogenic diet might opt for a device to measure ketone levels in their blood, gauging whether they’ve achieved a state known as nutritional ketosis. While the diet’s integration into mainstream culture has sparked considerable debate regarding its benefits, with certain medical groups expressing reservations, there is a burgeoning focus, including ongoing clinical trials, on its potential impact, not solely on obesity but also on a range of other health conditions.
“It’s not merely a passing trend in diets,” asserts Dr. Shebani Sethi, leading the research on the ketogenic diet’s potential for mental health at Stanford University. “It’s a bona fide medical intervention.” Originating over a century ago as a treatment for pediatric epilepsy, the ketogenic diet has experienced a resurgence in that field over the past three decades.
“It stands as a standard of care for epilepsy,” notes Dr. Eric Kossoff, a pediatric neurologist at Johns Hopkins University. Given its established efficacy in epilepsy, there is a rationale for exploring its application in psychiatry, considering the interconnectedness of these conditions. Drawing parallels, Dr. Palmer emphasizes the common practice of prescribing seizure medications for various psychiatric disorders, indicating a precedent for such off-label use in mental health.
The metabolic connection
There’s a well-documented link between various psychiatric conditions and metabolic issues such as high blood sugar, insulin resistance, Type 2 diabetes, obesity, and hypertension. People facing psychiatric disorders are at an elevated risk, and it’s not solely due to the potential side effects of psychiatric medications like weight gain. Research indicates that these metabolic challenges can manifest even before individuals with severe mental illness start medication or receive a diagnosis.
Dr. Dost Öngür, Chief of the Division of Psychotic Disorders at McLean Hospital and a professor at Harvard Medical School, notes that there has long been an awareness of abnormalities in the metabolism of the brain among individuals with severe mental illness. This understanding predates any exploration of the ketogenic diet’s impact.
The evidence of energy-related issues in both the brain and the body has been accumulating in psychiatry for decades, unrelated to the ketogenic diet. Although no direct causal relationship is established, Dr. Öngür, whose work focuses on this theme in bipolar and schizophrenia, suggests that the numerous connections warrant further exploration. The data is robust enough to raise suspicion that metabolic problems may not be mere bystanders but could potentially play a direct role in the development, severity, or course of psychiatric conditions, according to Ede.
The rationale behind the potency of keto
So, how does a diet initially designed to halt seizures also wield potent effects on challenging psychiatric conditions? Even after extensive research on epilepsy, scientists remain uncertain about the exact mechanisms responsible for its efficacy in treating seizures.
Dominic D’Agostino, a professor at the University of South Florida specializing in molecular pharmacology and physiology, describes the ketogenic diet as more of a “shotgun” than a “bullet” due to its impact on various mechanisms. In ketosis, the body shifts to utilizing ketones, derived from the breakdown of liver fat, instead of glucose, altering metabolic pathways.
The diet’s elimination of carbohydrates leads to lowered blood sugar and improved insulin sensitivity. According to Dr. Kossoff, this reduces pressure on the delicate insulin signaling system, providing cells with an alternative fuel source that may rejuvenate parts of the brain.
Scientists like Palmer propose that mitochondrial issues, central to mental illness, play a crucial role. Ana Andreazza, a professor at the University of Toronto, explores the biological pathways that make individuals with psychiatric conditions susceptible to mitochondrial dysfunction, leading to a detrimental “metabolic shift.”
The cumulative damage to these vital powerhouses results in increased lactate production, indicative of disrupted cellular processes. The ketones may aid mitochondria by alleviating oxidative stress and providing an alternative energy source, potentially restoring normal mitochondrial function and metabolic health, as explained by D’Agostino. This restoration, in turn, contributes to the revival of neurotransmitter systems and improved blood flow to the brain, presenting compelling findings for various psychiatric disorders.
Researchers seek additional clues.
The impact of ketosis on mitochondria is a leading hypothesis for the potential effectiveness of keto diets, yet it might not provide the complete picture. Current data on the diet’s effects on the brain largely stems from epilepsy and neurological disease research, revealing parallels with serious mental illnesses such as schizophrenia, major depression, and bipolar disorder. Commonalities include brain inflammation, oxidative stress, mitochondrial dysfunction, and glucose and insulin issues. While limited human studies exist, ongoing clinical trials aim to unravel the intricacies.
Dr. Deanna Kelly explores whether the diet’s benefits could arise from alterations in the gut microbiome, emphasizing the potential influence on behavior and the brain. As a psychiatry professor at the University of Maryland, Kelly leads an inpatient trial on the ketogenic diet for schizophrenia. Other researchers delve into the diet’s impact on neurotransmitters like GABA, known for its inhibitory role in the brain. Dr. Mary Phillips, studying dopamine’s effects on the reward circuit in bipolar disorder, believes this avenue may elucidate the therapeutic effects of the keto diet. In her recent clinical trial, Phillips raises a practical question about identifying individuals for whom the ketogenic diet is most suitable, acknowledging the challenges of starting such a regimen.
Preliminary findings exhibit potential.
A significant portion of the current evidence regarding the ketogenic diet’s potential for mental health is derived from case reports, observational data, and open trials, laying the foundation for more rigorous studies. Existing research demonstrates positive outcomes in both mental and metabolic health. In a small pilot study led by Iain Campbell, participants experienced weight loss, reduced blood pressure, improved mood, increased energy, decreased anxiety, and reduced impulsivity as ketone levels rose. Notably, blood lactate levels, indicative of mitochondrial dysfunction, decreased, mirroring the effects of anti-seizure medications.
In a recent study from Toulouse, France, the largest to date examining hospitalized patients with severe mental illness, those adhering to the ketogenic diet exhibited substantial improvements in depression and psychosis symptoms, with 43% achieving clinical remission. At Stanford, Dr. Shebani Sethi’s pilot study found clinically meaningful improvement in the majority of patients with schizophrenia or bipolar disorder, with nearly half achieving recovery. A quarter of participants with metabolic syndrome reversed the condition by the study’s end.
While the initial data is deemed intriguing by experts like Dr. Anissa Abi-Dargham, caution is urged, recognizing that the field is in its early stages. Dr. Drew Ramsey expresses skepticism, emphasizing the need for solid clinical data amidst the current attention and potential hype surrounding the ketogenic diet in mental health. Proponents acknowledge the diet’s potency but stress its limitations, cautioning against viewing it as a universal cure for mental illness.
The field of metabolic psychiatry gains momentum.
The growing enthusiasm for a high-fat, low-carb diet mirrors a broader movement recognizing the connection between metabolic health and mental illness. Metabolic psychiatry, a term coined by Dr. Shebani Sethi when she launched Stanford’s program in 2015, explores how addressing metabolic conditions like high blood sugar, insulin resistance, and obesity might enhance psychiatric well-being. Beyond the ketogenic diet, medications are also under investigation, including drugs that increase insulin sensitivity, the hormone facilitating glucose entry into cells.
For Sethi, with a background in obesity medicine and psychiatry, this approach is instinctive. Her realization of keto’s potential for psychiatric patients dates back to medical school, witnessing a woman with treatment-resistant schizophrenia benefit not only in weight management but also in alleviating hallucinations.
A recent clinical trial reinforces the promise of targeting metabolic issues beyond the ketogenic diet. Patients with treatment-resistant bipolar depression and insulin resistance, without Type 2 diabetes, were prescribed the diabetes drug metformin. By the study’s end, half of the participants had reversed their insulin resistance, leading to significant improvements in psychiatric symptoms, even after prolonged illness without remission, as highlighted by Dr. Cynthia Calkin of Dalhousie University in Canada, who led the study.
A boost to well-being
Patients and clinicians aren’t waiting for the outcomes of larger trials to experiment with the ketogenic diet. Online, patients share their experiences and challenges with the diet, while doctors like Sethi and Ede, who trains other clinicians, routinely incorporate it into patient treatment. Lori Katz, diagnosed with bipolar disorder and struggling with chronic pain, binge eating, and weight gain, turned to the ketogenic diet under Sethi’s guidance. Katz, a dog trainer from Santa Cruz, California, noticed rapid weight loss, increased satisfaction with her meals, and a positive change in mood, describing the keto diet as a “tailwind” propelling her towards a better future.
For Katz, the diet became a transformative experience, leading her to engage in physical activities like going to the gym and taking longer walks. After years without a romantic drive, she found a girlfriend. While acknowledging the challenges of maintaining strict adherence to the diet, Katz emphasizes its impact on resilience, optimism, and having a valuable tool in managing her mental health. Despite living with a mental illness, she expresses the tangible benefits of the ketogenic diet, affirming its role in enhancing her overall well-being.
Is it achievable?
Adhering to any diet can be challenging, especially one that involves giving up common comfort foods like bread and sweets. In Campbell’s study, about a quarter of participants withdrew, a trend observed in other pilot trials with the ketogenic diet. Dr. Rif El-Mallakh, a psychiatrist at the University of Louisville, has been intrigued by the diet for over two decades, citing early success but struggling with patient adherence over the years. While he remains less enthusiastic, doctors already using the diet emphasize that with sufficient education and support, patients can succeed.
Dr. Matt Bernstein, Chief Medical Officer at Ellenhorn, a psychiatric recovery program in Boston, notes striking results in some patients using the ketogenic diet. He tailors the approach, gradually reducing carbohydrate intake for sustainability. Bernstein underscores the importance of a gradual transition for many individuals, aiming for long-term adherence rather than short-term commitment. While not all psychiatrists are trained to offer the diet, the number is growing. Bernstein and others recommend medical supervision, particularly for those with a history of serious mental illness, as adjustments to lab work and medications may be necessary.
Despite the optimism surrounding the ketogenic diet’s potential, many questions remain unanswered. Iain Campbell, in his initial research, is already hearing transformative stories from participants, describing significant life changes and reconnections with family. While acknowledging the positive outcomes, the medical community continues to explore and refine the understanding and application of the ketogenic diet in mental health.
