The ketogenic diet has become a popular strategy for weight loss in the United States. However, its effects on mental health have been a subject of debate. While some sources suggest that the keto diet may help alleviate anxiety and depression, others argue that it could potentially cause or worsen these conditions. Research in this area is still evolving, and while initial findings suggest a link between the keto diet and mental health, more comprehensive human studies are needed to confirm these effects and establish the underlying biological mechanisms.
| Characteristics | Values |
|---|---|
| Ketogenic diet causing anxiety | A study on rats showed that a high-fat diet caused an increase in anxiety. However, this was not a keto diet, and the rats were not in a metabolic state of ketosis. |

What You'll Learn
Ketogenic diet and anxiety remission
The ketogenic diet has become one of the most popular diet strategies in the United States. It involves strictly limiting carbohydrates, which forces the body to change how it obtains energy. By reducing carbs, the body is forced to burn fat for fuel, resulting in ketosis. While the keto diet is often associated with weight loss, its impact on mental health has also come under scrutiny.
Some studies have linked high-fat diets to increased anxiety. For example, a study on rats showed that a diet high in saturated fats led to a decrease in gut microbiome diversity, weight gain, and behaviours associated with anxiety. However, it is important to note that this study was not specifically about the keto diet, and the rats were not in a metabolic state of ketosis.
On the other hand, there is emerging research suggesting that a ketogenic diet may actually help reduce anxiety. Nutritional ketosis, achieved through a ketogenic metabolic therapy (KMT) or therapeutic ketogenic diet (KD), is a natural state where the body's energy needs are met through a high-fat, moderate-protein, low-carbohydrate diet. This shift in metabolism has been shown to have beneficial effects on the brain's cellular energy status, increasing mitochondrial density and improving mitochondrial morphology, which is often altered in mood disorders.
Furthermore, KMT has been found to directly modulate fundamental metabolic disturbances associated with anxiety disorders, including insulin resistance, inflammation, oxidative stress, and alterations of the gut microbiome. A case study involving three adults with major depression and generalized anxiety disorder found that a personalized ketogenic metabolic therapy program, including dietary interventions and lifestyle modifications, resulted in complete remission of anxiety within 7 to 12 weeks.
While the potential anxiety-reducing benefits of a ketogenic diet are intriguing, it is important to note that more research is needed. Nutritional intervention may be a promising strategy for anxiety remission, but further studies are required before specific recommendations can be made. Additionally, it is always advisable to consult with a healthcare professional before starting any new diet, especially when managing mental health conditions.

High-fat diets and anxiety
There is a growing body of literature that links nutrition to mood and anxiety. While the ketogenic diet has been one of the most popular diet strategies in the United States, some people are concerned that such a high-fat diet may negatively impact their health and cause anxiety.
Indeed, a recent study found that a diet high in saturated fats led to increased anxiety in rats. The rats exhibited behaviours associated with anxiety and had a marked drop in the diversity of their gut microbiomes. However, it is important to note that this study was not conducted on humans and the diet consumed by the rats was not a keto diet.
On the other hand, there is also evidence to suggest that ketogenic diets can be beneficial for mental health and may even help treat anxiety disorders. Nutritional ketosis is a natural state where the body's energy and protein synthesis needs are met with a high-fat, moderate-protein, low-carbohydrate diet, resulting in sustained elevations of serum ketones and fatty acids. This type of diet has been shown to directly change the brain's cellular energy status, increase mitochondrial density, and improve mitochondrial morphology, which is often altered in mood disorders. Additionally, ketogenic diets can improve the body's antioxidant activity, helping to reverse some of the damage caused by free radicals in the cells. This can be particularly beneficial for people with depression, who often have high levels of oxidative stress.
Furthermore, ketogenic diets have been found to prevent depression, improve sleep, and slow down the growth of cancer cells. In addition, ketogenic metabolic therapy has been shown to be effective in treating major depression and generalized anxiety disorder in adults, with complete remission occurring within 7-12 weeks.
However, it is important to note that not everyone adjusts well to ketosis and it may cause side effects such as headaches, sleep disturbances, cramping, and fatigue. Additionally, there is currently insufficient evidence to recommend ketogenic diets as a treatment for mental disorders, and it may not be suitable for everyone, especially those with pre-existing health conditions.
In conclusion, while there is some evidence to suggest that high-fat diets may increase anxiety, the impact of ketogenic diets on anxiety is still not fully understood and more research is needed. It is important to consult with a healthcare professional before starting any new diet, especially if you have a history of mental health issues.

Nutritional ketosis and anxiety
Nutritional ketosis is a natural metabolic state in which the body's energy and protein synthesis needs are met by a high-fat, moderate-protein, and low-carbohydrate diet. This shift in metabolism results in sustained elevations of serum ketones and fatty acids, leading to several biological effects that impact brain function and mood regulation.
The ketogenic diet has been proposed as a potential treatment for anxiety disorders due to its impact on metabolic processes in the brain. Specifically, the diet addresses fundamental metabolic disturbances within neurons, including insulin resistance, inflammation, oxidative stress, and alterations in the gut microbiome, which are all implicated in anxiety disorders. By improving insulin sensitivity and reducing inflammation and oxidative stress, the ketogenic diet may help to alleviate some of the underlying causes of anxiety.
Additionally, the ketogenic diet's impact on the gut microbiome may also play a role in reducing anxiety. The diet has been shown to increase the diversity of gut microbiota, which can influence the gut-brain axis and the production of neuroactive compounds involved in neurotransmission. This interaction between the gut and the brain may contribute to the anxiolytic effects observed in some individuals following a ketogenic diet.
However, it is important to note that the link between the ketogenic diet and anxiety relief is not yet fully understood. While some studies have shown positive outcomes, with complete remission of anxiety disorders within 7-12 weeks of starting the diet, there is still limited data on its long-term effectiveness. Furthermore, not everyone adjusts well to ketosis, and some individuals may experience negative side effects, including headaches, sleep disturbances, cramping, fatigue, nutrient deficiencies, kidney problems, liver issues, constipation, and mood swings, which could potentially exacerbate anxiety symptoms.
While nutritional ketosis shows promise as a complementary approach to managing anxiety, it should not be considered a standalone treatment. Consulting with a qualified healthcare professional is essential before starting any new diet, especially for individuals with pre-existing health conditions or complex psychiatric comorbidities.

Ketogenic diet and mood swings
The ketogenic diet has been linked to both an increase and decrease in anxiety.
Some studies have shown that a high-fat diet can lead to an increase in anxiety. Researchers in Colorado found that rats fed a diet high in saturated fats exhibited behaviours associated with increased anxiety. However, it is important to note that these rats were not in a metabolic state of ketosis, and the findings cannot be directly applied to the potential effects of a keto diet.
On the other hand, there is emerging research that suggests a ketogenic diet may help reduce anxiety. This is due to several factors. Firstly, a ketogenic diet can improve insulin sensitivity and stabilize blood sugar levels, which is important because insulin resistance and glucose intolerance have been linked to anxiety. Secondly, ketogenic diets can reduce inflammation, which is another factor that contributes to anxiety disorders. Finally, ketogenic diets can improve mitochondrial morphology, which has been shown to be altered in mood disorders.
There have been case studies of adults with major depression and generalized anxiety disorder who underwent ketogenic metabolic therapy. After 7-12 weeks, these individuals experienced complete remission of their anxiety disorders, along with improvements in flourishing, self-compassion, and metabolic health.
However, it is important to note that not everyone adjusts well to ketosis. Some individuals may experience mood swings and other symptoms such as headaches, sleep disturbances, cramping, and fatigue when transitioning to a keto diet.
While there is some evidence that a ketogenic diet may help reduce anxiety, more research is needed before it can be recommended as a treatment option. Currently, there is insufficient evidence to support the use of the keto diet in mental disorders, and it is not a recommended treatment.

Ketogenic diet and gut-brain axis
The ketogenic diet (KD) is a high-fat, low-carbohydrate, and adequate-protein diet that has gained popularity in recent years in the context of neurological diseases. The diet has been used to control seizures for over 100 years, as it was initially developed for the treatment of epilepsy in 1921.
In recent years, the microbiome–gut–brain axis has become increasingly important in the pathogenesis of neurological diseases. The composition of the microbiota may influence the development and inhibition of disease progression, representing a potential therapeutic strategy for neurological disorders. The multi-target nature of the ketogenic diet makes it an attractive complementary therapy that may enhance the effectiveness of available treatments for CNS diseases, which have little effect due to the complexity of the pathogenesis.
The gut-brain axis is involved in the perception and regulation of visceral sensitivity, linking peripheral GI functions with the sensitive and cognitive centers in the brain. Altered communication between the gut and the brain can contribute to intestinal dysfunctions such as visceral pain, disturbed GI motility, and intestinal bowel syndrome (IBS). IBS is a gastrointestinal (GI) functional disorder characterized by GI motor and sensory dysfunctions in the absence of structural abnormalities. It is highly prevalent, chronic, recurrent, and remitting, and often overlaps with anxiety and depression.
Studies have shown that the ketogenic diet improves the gut-brain axis in a rat model of irritable bowel syndrome (IBS). The neuroprotective nature of the diet modulates the levels of different neurotransmitters and neurotrophins, improving the altered 5-HT and BDNF systems. The diet down-regulated the increased mucosal 5-HT without affecting transporter and receptor levels, and improved brain BDNF levels.
The ketogenic diet has also been studied as a nutritional strategy for major depressive disorder (MDD), which is a leading cause of disability worldwide. Traditional pharmacological treatments are ineffective for a significant proportion of patients, so nutritional interventions are a promising alternative. The diet has been shown to modulate inflammation, gut-, and metabolic-health, which positively impact cognition.

Frequently asked questions
There is limited research on the effects of the ketogenic diet on anxiety. While some studies have found that a high-fat diet can increase anxiety, these studies have been conducted on rats and may not apply to humans. Other studies have shown that a ketogenic diet can lead to a complete remission of anxiety disorders in humans.
The ketogenic diet is a high-fat, moderate-protein, and low-carbohydrate diet that forces the body to change how it obtains energy. With carbohydrates largely out of the picture, the body turns to burning fat for energy, resulting in a state called ketosis.
The ketogenic diet has been found to have several potential benefits, including weight loss, improved sleep, and slower cancer cell growth. The diet can also help stabilize blood sugar levels and increase insulin sensitivity, which can be beneficial for people with depression and anxiety.
