Keto Diet: A Natural Remedy For Depression And Mood Swings?

The ketogenic diet is a high-fat, low-carbohydrate, and adequate-protein diet. Eating this way triggers a metabolic process called ketosis, which causes the body to burn fat instead of carbohydrates for energy. The keto diet was initially developed to manage seizures in people with epilepsy, but it is now widely used as a weight loss method.

The keto diet may help relieve depression due to its positive effects on the brain. Research suggests that this eating plan may affect the brain and mood, and scientists are researching its potential uses for mental health conditions, such as depression.

The keto diet may improve depression by:

- Increasing substances that play critical roles in managing stress, anxiety, and mood

- Improving mitochondrial function

- Decreasing oxidative stress

- Regulating insulin function

- Decreasing inflammation

However, the keto diet may also cause depression. Some people may experience adverse effects from this diet, such as keto flu, which could affect their mood. Additionally, any diet that limits certain foods may cause nutrient deficiencies, which can aggravate mental health conditions.

Keto may reduce neuroinflammation

The ketogenic diet has been found to have anti-inflammatory properties and may help ease inflammation in the brain, which can contribute to depression, other mood disorders, and cognitive decline.

Supporting Neuron Structure

The high-fat content of the keto diet may help optimise the health of brain cells, or neurons. Neurons contain a fatty protective layer called the myelin sheath, and dietary fat is essential to help the body create these structures.

Improved Physical Health

Keto may help improve other aspects of physical health, like weight or blood glucose control. This alone could help to improve mood and depressive symptoms, as sub-optimal physical health can have a significant impact on mental health.

Better Gut Health

A well-planned keto diet that's rich in high-quality fats, fibre-rich vegetables, nuts, and seeds can help support your gut microbiome. There is a lot of "cross-talk" between the brain and the gut via the gut-brain axis, so improved gut health could translate to better brain health, too.

Increased Gamma-Aminobutyric Acid (GABA)

Ketogenic diets may increase levels of the neurotransmitter GABA, which could help some antidepressant drugs to be more effective.

Studies Supporting the Use of Keto for Depression

The effect of diet on mental health isn't easy to study. A meta-analysis on low-carbohydrate diets for depression and anxiety found no effect. However, this analysis included low-carbohydrate diet studies in addition to ketogenic diet studies. Well-designed studies specifically on ketogenic diets are still necessary to understand their effect on depression.

Most of the current research on the effects of ketosis on the brain comes from animal studies. In rodents with depression, a ketogenic diet has been shown to significantly reduce "depression-like behaviours".

Potential Side Effects

The keto diet can cause side effects, especially in the first few weeks of the diet when the body is making a huge metabolic shift from burning carbs to burning fat for fuel. In the first two weeks to one month of following a keto diet, you may experience a cluster of symptoms nicknamed "keto flu". It's thought that the keto flu is caused by changes to the way the body stores electrolytes and fluid when shifting into ketosis.

Keto may support neuron structure

The ketogenic diet is a high-fat, low-carbohydrate, and adequate-protein diet that triggers a metabolic process called ketosis, causing the body to burn fat instead of carbohydrates for energy. The diet was initially developed to manage seizures in people with epilepsy.

The diet may support neuron structure by increasing the levels of gamma-aminobutyric acid (GABA), a neurotransmitter that plays a critical role in managing stress, anxiety, and mood. Low levels of GABA have been linked to clinical depression. The ketogenic diet may increase the circulation of substances that transmit neurons, potentially improving depressive symptoms.

The diet may also improve mitochondrial function. Mitochondria are cellular components that generate the energy cells need to function. Mitochondrial dysfunction has been linked to depression. The ketogenic diet may make it easier to produce adenosine triphosphate (ATP), an energy-providing compound, in people with mitochondrial dysfunction.

Additionally, the diet may decrease oxidative stress. Ketogenic diets can improve the body's antioxidant activity, helping to reverse some of the damage caused by free radicals in the cells.

Ketogenic Diet and Neuron Structure

The ketogenic diet may support neuron structure by increasing the levels of gamma-aminobutyric acid (GABA), a neurotransmitter that plays a critical role in managing stress, anxiety, and mood. Low levels of GABA have been linked to clinical depression.

Animal studies have found that following a ketogenic diet may increase circulating levels of GABA, potentially improving depressive symptoms. However, more research is needed to confirm these findings.

By increasing the levels of GABA, the ketogenic diet may promote calmness and relaxation, similar to the effects of benzodiazepines, which are medications used to treat various conditions, including anxiety.

The ketogenic diet may also influence other neurotransmitters like dopamine and serotonin, which regulate mood, as well as the gut microbiome, which affects behavior and stress response.

The ketogenic diet may support neuron structure by increasing the levels of GABA, a neurotransmitter that plays a critical role in managing stress, anxiety, and mood. The diet may also improve mitochondrial function and decrease oxidative stress, which have both been linked to depression. However, more research is needed, especially in human studies, to fully understand the effects of the ketogenic diet on neuron structure and its potential benefits for depression.

Keto may improve physical health

The keto diet may improve physical health in several ways, which could have a positive knock-on effect on mental health and depression.

Weight Loss

The keto diet is a high-fat, low-carbohydrate, and adequate-protein diet. It is a mainstream weight loss method that causes the body to burn fat instead of carbohydrates for energy.

Blood Glucose Control

The keto diet can help to stabilise blood sugar levels and increase the body's sensitivity to insulin. This can be beneficial for people with diabetes or insulin resistance.

Gut Health

A well-planned keto diet, rich in high-quality fats, fibre-rich vegetables, nuts, and seeds, can support a healthy gut microbiome. There is a lot of communication between the brain and the gut, so improved gut health could lead to better brain health.

Cardiovascular Health

The keto diet has been linked to better cardiovascular health. It may help to reduce inflammation and lower the risk of heart disease.

Cancer

The keto diet may also slow down the growth of cancer cells since cancer cells rely on sugars to thrive.

Sleep

Some people on the keto diet have reported finding it easier to fall asleep.

Other Benefits

The keto diet has been found to be beneficial in treating migraines, epilepsy, Alzheimer's disease, Parkinson's disease, multiple sclerosis, and chronic fatigue.

Keto may improve gut health

The ketogenic diet may improve gut health, which can have a positive impact on mental health. The gut and the brain are connected via the gut-brain axis, and a well-planned keto diet that is rich in high-quality fats, fibre-rich vegetables, nuts, and seeds can support the gut microbiome.

The keto diet is high in fat, and fat is essential for the body to create the myelin sheath, a fatty protective layer around brain cells or neurons. The keto diet may also increase levels of the neurotransmitter gamma-aminobutyric acid (GABA), which plays a key role in managing stress, anxiety, and mood.

In addition, the keto diet has powerful anti-inflammatory properties and may help reduce neuroinflammation, which can contribute to depression and other mood disorders.

While most studies on the effects of the keto diet on depression have been conducted on animals, there is a lot of anecdotal evidence to support its potential benefits for mental health.

Keto may increase gamma-aminobutyric acid (GABA)

Gamma-aminobutyric acid, or GABA, is a naturally occurring amino acid that acts as a neurotransmitter in the brain. It is an inhibitory neurotransmitter, meaning it blocks or inhibits certain brain signals and decreases activity in the nervous system. This produces a calming effect, helping with feelings of anxiety, stress, and fear.

Keto may increase GABA levels. Animal studies have found that following a ketogenic diet may increase circulating levels of GABA, potentially improving depressive symptoms. However, more research is needed to confirm this.

GABA supplements are available, but their effectiveness is uncertain. When consumed as a supplement or food, it is unclear how much GABA reaches the brain. Some research suggests only small amounts may enter the brain.

GABA is also found in certain foods, including fermented ones like kimchi, miso, and tempeh. It is also present in green, black, and oolong tea, as well as brown rice, soy, adzuki beans, and certain vegetables. However, it is unclear if consuming these foods allows GABA to reach the brain.

While the link between keto and increased GABA levels requires further study, the potential for GABA to positively impact mental health is promising.
