Keto diet to treat mental illness: everything you need to know

Introduction

The ketogenic diet, or "keto," has dominated the health and fitness sector in recent years.. Characterized by a high-fat, low-carbohydrate, and moderate-protein composition, this dietary approach has been touted for its ability to promote weight loss, enhance energy levels, and improve overall health.

But beyond its physical health benefits, there is a growing body of research and anecdotal evidence suggesting that the keto diet may also positively impact mental health. From improving mood and energy regulation to potentially alleviating symptoms of depression, anxiety, and even more severe mental health disorders, the ketogenic diet is attracting attention as a potential therapeutic tool.

As the understanding of the gut-brain connection deepens and more focus is placed on the role of nutrition in mental wellness, exploring the effects of the keto diet on mental health becomes increasingly pertinent. This article aims to provide a comprehensive overview of the keto diet's potential benefits, mechanisms, and considerations for mental health, based on the latest research and expert insights.

Understanding the Keto Diet

The ketogenic diet is a high-fat, low-carbohydrate, and moderate-protein eating pattern that aims to shift the body's primary fuel source from glucose (derived from carbohydrates) to ketones, which are produced from the breakdown of fats in the liver. This metabolic state is referred to as ketosis.

Historical Background

The keto diet was originally developed in the 1920s as a treatment for epilepsy. The high-fat, low-carb approach was found to be effective in reducing seizure activity, and it remains a well-established therapy for drug-resistant epilepsy, especially in children.

Physiological Changes

When following a ketogenic diet, individuals typically reduce their carbohydrate intake to less than 50 grams per day, and sometimes as low as 20 grams. This restriction on carbs encourages the body to deplete its glucose stores and shift towards burning fat for energy.

During ketosis, the body produces ketone bodies (acetone, acetoacetate, and beta-hydroxybutyrate), which can cross the blood-brain barrier and provide an alternative fuel source for the brain and central nervous system. This change in fuel metabolism is thought to have significant implications for brain health and function, including potential benefits for mental health.

The Gut-Brain Connection

A key aspect of understanding the link between the keto diet and mental health lies in the gut-brain axis. The gut microbiome, composed of trillions of microorganisms, plays a crucial role in maintaining overall health, including mental health.

Influence on Gut Bacteria

The ketogenic diet can significantly influence the composition and diversity of gut bacteria. Studies have shown that a keto diet increases the abundance of certain beneficial bacteria, such as Akkermansia and Lactobacillus, which have been linked to improved gut barrier function and anti-inflammatory effects. These changes in the gut microbiome may, in turn, have positive impacts on brain function and mental health.

Potential Mechanisms

The gut-brain axis refers to the bidirectional communication between the gut and the brain. This connection allows the gut microbiome to influence brain development, function, and behavior, including mood, cognition, and stress response.

One proposed mechanism is through the production of short-chain fatty acids (SCFAs) by certain gut bacteria. SCFAs, such as butyrate, propionate, and acetate, have anti-inflammatory properties and can cross the blood-brain barrier, influencing neurotransmitter production and neuroplasticity.

Additionally, the gut microbiome plays a role in the production and regulation of key neurotransmitters, such as serotonin and GABA, which are essential for mood regulation and healthy brain function.

The ketogenic diet and brain health

The ketogenic diet has been shown to have neuroprotective effects, and its potential mechanisms relate to improved energy metabolism in the brain, reduced inflammation, and positive influences via the gut-brain axis.

Improved Energy Metabolism

Ketone bodies provide an efficient and alternative fuel source for the brain. The brain typically relies on glucose for energy, but during ketosis, it utilizes ketones, which have been shown to enhance mitochondrial function and improve energy metabolism in the brain. This improved energy supply may contribute to the optimization of brain function and resilience.

Reduced Inflammation

Inflammation is a common underlying factor in many mental health disorders. The keto diet has been shown to reduce inflammation in the brain and throughout the body. This anti-inflammatory effect may be due to the reduction of pro-inflammatory stimuli, such as glucose and advanced glycation end products (AGEs), as well as the increase in anti-inflammatory gut bacteria and subsequent production of SCFAs.

Impact on Neurotransmitters and Neural Excitability

The keto diet may also influence the production and function of neurotransmitters, the chemical messengers in the brain. For example, GABA, the primary inhibitory neurotransmitter, is produced from glutamate, which is abundant during ketosis. This may contribute to an improved mood and reduced anxiety.

Additionally, the keto diet has been shown to reduce neural excitability, which is implicated in seizure activity and certain mental health disorders.

Keto Diet for Specific Mental Health Conditions

Bipolar Disorder

A pilot study published in 2022 explored the effects of a ketogenic diet on individuals with bipolar disorder. The small-scale trial found that participants following the keto diet for 12 weeks experienced reduced symptom severity and improved mood stability compared to a control group. The diet was well-tolerated, and no significant side effects were reported.

Potential Effects

The potential benefits of the keto diet for bipolar disorder may lie in its ability to regulate mood and energy levels. By stabilizing energy metabolism and reducing fluctuations in glucose and insulin levels, the keto diet may help minimize the highs and lows associated with bipolar disorder.

Schizophrenia

Researchers at Stanford University conducted a study to examine the effects of a 12-week ketogenic diet intervention in patients with schizophrenia. The findings, published in 2018, revealed significant improvements in psychiatric symptoms and metabolic health. Participants also experienced a reduction in weight and waist circumference, highlighting the potential for keto to address the increased risk of metabolic syndrome in this population.

Inpatient Trial

An inpatient trial, published in 2021, investigated the role of the gut microbiome in the therapeutic effects of the keto diet for schizophrenia. The study found that patients with schizophrenia who followed a ketogenic diet for 8 weeks showed improvements in both psychiatric symptoms and metabolic markers. Additionally, changes in the gut microbiome composition were observed, suggesting a potential link between the diet's impact on gut bacteria and improvements in mental health.

Depression

While more large-scale studies are needed, anecdotal reports and small-scale studies suggest the potential benefits of the keto diet for depression. A proposed mechanism is the reduction of inflammation, as depression has been linked to increased levels of inflammatory markers. By reducing inflammation and improving energy metabolism in the brain, the keto diet may help alleviate depressive symptoms.

Anxiety and PTSD

There are numerous anecdotal reports from individuals who have experienced reduced anxiety and improved sleep while following a ketogenic diet. The potential anxiolytic effects of ketosis may be related to its impact on the stress response and the production of neurotransmitters involved in anxiety regulation, such as GABA.

Metabolic Psychiatry

The concept of metabolic psychiatry is gaining traction, highlighting the importance of addressing metabolic dysfunction in the treatment of mental health disorders. This perspective focuses on the role of energy conversion and metabolism in brain health and function.

Energy Conversion Perspective

The brain is highly metabolically active and requires a constant supply of energy to function optimally. The metabolic theory of mental health suggests that impairments in energy conversion and utilization can lead to neurological dysfunction, contributing to the development or exacerbation of mental health disorders.

Role of Keto in Restoring Metabolic Health

The keto diet has been shown to improve metabolic health by reversing metabolic syndrome, a cluster of conditions that include obesity, high blood sugar, high blood pressure, and abnormal cholesterol levels. By addressing these metabolic imbalances, the keto diet may help improve brain function and reduce the risk or severity of mental health disorders.

Metabolic Benefits of Keto for Mental Health

Reversal of Metabolic Syndrome

The ketogenic diet has been widely studied for its metabolic benefits, particularly in the context of obesity and type 2 diabetes. By reducing carbohydrate intake and increasing fat burning, the keto diet helps improve insulin sensitivity, reduce inflammation, and promote weight loss. These metabolic improvements can have a positive impact on overall health and may contribute to improved mental health.

Weight loss and improved insulin sensitivity

Obesity and insulin resistance are risk factors for various mental health disorders, and they often coexist. The keto diet's ability to promote weight loss and improve insulin sensitivity can help mitigate these risk factors, creating a favorable environment for mental health.

Reduced Inflammation

As mentioned earlier, inflammation is a common underlying factor in many mental health disorders. The anti-inflammatory effects of the keto diet, mediated through various mechanisms, can help reduce systemic inflammation, which has been linked to depression, anxiety, and cognitive decline.

Safety and Considerations

While the ketogenic diet has shown promise in treating mental health disorders, it is not without potential risks and side effects. It is important to approach this dietary intervention with caution and under medical supervision.

Potential Risks and Side Effects

Some individuals may experience an initial phase known as the "keto flu," characterized by symptoms like headache, fatigue, and irritability, which typically resolve within a few days to weeks. Ensuring adequate fluid intake and electrolyte supplementation can help minimize these symptoms.

Longer-term risks may include nutrient deficiencies, particularly if the diet is not well planned or maintained for extended periods. Kidney stones and an increased risk of bone fractures have also been associated with long-term ketogenic diets, although more research is needed to fully understand these risks.

Medical supervision and individualization

It is crucial to consult with a healthcare professional before starting a ketogenic diet, especially for those with pre-existing health conditions or those taking medications. The diet should be tailored to the individual's specific needs, and regular monitoring is essential to ensure safety and effectiveness.

Cardiovascular health concerns

One of the concerns surrounding high-fat diets relates to cardiovascular health. However, recent meta-analyses have suggested that ketogenic diets do not negatively impact cardiovascular risk factors and may even lead to improvements in lipid profiles and other markers of heart health. Nonetheless, those with existing heart conditions should proceed with caution and under medical guidance.
