Keto's Impact On Brain Swelling: What You Need To Know

The ketogenic diet is a low-carb, high-fat diet that has been shown to reduce brain inflammation. Brain inflammation is an immune response to aging, injury, infection, or other conditions. This can negatively impact cognitive function, mood, behaviour, and disease risk. The ketogenic diet has been shown to reduce inflammation and seizures in mice, improve a mouse model of multiple sclerosis, and enhance cognitive performance in non-demented elderly people.

The ketogenic diet is also used to treat epilepsy and may prove helpful in Alzheimer's and Parkinson's disease. The diet is difficult to follow, especially for people who are acutely ill. However, the potential benefits of the ketogenic diet for brain health are promising.

Ketogenic diets may reduce inflammation in the brain by lowering the NADH:NAD+ ratio, which activates a protein that turns off inflammation

Ketogenic diets are low-carbohydrate, high-fat regimens that have been used to treat epilepsy and other neurological illnesses. Research has shown that these diets may work by lowering inflammation in the brain.

The ketogenic diet changes the way the body uses energy. When the body is deprived of glucose derived from carbohydrates, it starts using fat as an alternative source of energy. This change in metabolism is called ketosis. In ketosis, the body breaks down fat into ketones and ketoacids, which it can use as alternative fuels.

Ketogenic diets have been found to reduce inflammation, improve outcomes after brain injury, and even extend lifespan in rodents. However, the benefits of ketogenic diets are less well-established in humans due to the difficulty in maintaining ketosis.

Recent research has uncovered the mechanism by which ketogenic diets curb brain inflammation. The key lies in the reduction of the NADH/NAD+ ratio, which activates a protein called CtBP that suppresses the activity of inflammatory genes.

In a study by Dr. Raymond Swanson and colleagues, the researchers used a molecule called 2-deoxyglucose (2DG) to block glucose metabolism and induce ketosis in rodents with brain inflammation. They found that 2DG reduced inflammation levels to almost healthy levels. The restricted glucose metabolism lowered the NADH/NAD+ ratio, which in turn activated the CtBP protein.

The significance of this finding is that it paves the way for new drug targets that could achieve the anti-inflammatory effects of a ketogenic diet without having to follow the strict dietary regimen. This is especially important for patients who are unable to follow the ketogenic diet due to other health reasons.

The ultimate therapeutic goal is to develop a drug that can act on the CtBP protein to mimic the anti-inflammatory effects of the ketogenic diet, providing a potential treatment for conditions characterized by inflammation, such as Alzheimer's and Parkinson's disease.

Ketogenic diets may reduce brain inflammation by keeping blood sugar low

Brain inflammation is an immune response in the brain caused by ageing, injury, infection, or other conditions. This can negatively impact cognitive function, mood, behaviour, and the risk of developing diseases like Alzheimer's and Parkinson's. There are two main causes of brain inflammation: acute infection or injury, such as a concussion or traumatic brain injury (TBI), and chronic, systemic inflammation.

• Protecting Brain Cells After TBI: The ketogenic diet has been shown to protect brain cells in rats after TBI. This is because the diet lowers an important energy ratio called NADH:NAD+. The decrease in this ratio activates a protein called CtBP, which tells the body's genes to turn off inflammation.
• Lowering Blood Glucose: The ketogenic diet is very low in carbohydrates, which minimises blood sugar spikes. Ketone bodies like BHB also suppress blood sugar levels, and the diet lowers ghrelin, the hunger hormone, reducing cravings for carbohydrates. High blood sugar exacerbates brain damage in the context of brain injury or inflammation, and high levels of glucose in the brain may impair cognition.
• Boosting Adenosine: Adenosine is a brain chemical that is released during injury or illness and reduces pain and inflammation. The ketogenic diet has been shown to boost adenosine in mice.
• Reducing Reactive Oxygen Species (ROS): Burning sugar produces reactive oxygen species (ROS), which are molecules that can damage and inflame organs, including the brain, when produced in excess. Burning ketones produces fewer ROS and stimulates cleanup enzymes that remove these molecules.
• Boosting GABA and Lowering Glutamate: Gamma-aminobutyric acid (GABA) is an inhibitory neurotransmitter that has relaxing effects and may be neuroprotective. The ketogenic diet has been linked to increased GABA levels in rats and humans. Glutamate is an excitatory neurotransmitter that causes brain inflammation, and the ketone body acetoacetate may help reduce glutamate toxicity.

Other Brain Benefits of the Ketogenic Diet

• Better Cognition: Excess glucose can impair cognition, but ketones appear to enhance cognition. For example, rats fed a ketone-rich diet were better able to navigate a complex maze, and humans who supplemented their diet with MCT oil showed improved working memory, visual attention, and task switching.
• Reducing the Risk of Alzheimer's Disease: Alzheimer's disease is a neurodegenerative disorder and the sixth leading cause of death in the US. The ketogenic diet may help reduce the risk of Alzheimer's by improving mitochondrial function in the brain, decreasing systemic inflammation, and offsetting age-related cognitive decline.
• Treating Epilepsy: The ketogenic diet was originally developed to treat epilepsy and has been shown to be highly effective at reducing seizures in children and adults. This may be due to the diet's impact on potassium, glutamate, and GABA.

Ketogenic diets may reduce inflammation in the brain by increasing adenosine, a brain chemical that reduces pain and inflammation

The ketogenic diet is a low-carbohydrate, high-fat regimen that has been used to treat epilepsy and other neurological illnesses. Recent research suggests that the ketogenic diet may also help reduce inflammation in the brain by increasing adenosine, a brain chemical that has anti-inflammatory and pain-relieving properties.

The Ketogenic Diet and Brain Inflammation

Brain inflammation is an immune response that can be triggered by various factors such as aging, injury, or infection. This inflammation can have negative consequences on cognitive function, mood, behaviour, and the risk of neurodegenerative disorders. The ketogenic diet has been found to reduce inflammation in the brain, which may have potential benefits for individuals with neurological conditions.

The Role of Adenosine

Adenosine is a brain chemical that is released during injury or illness and has natural anti-inflammatory and pain-relieving properties. The ketogenic diet has been shown to increase adenosine levels in the brain, which may contribute to its anti-inflammatory effects.

In a study conducted on mice, researchers found that a ketogenic diet led to increased levels of adenosine, which was associated with a reduction in seizures. This suggests that the ketogenic diet may have a role in modulating adenosine levels and reducing inflammation in the brain.

Mechanisms of Action

The exact mechanisms by which the ketogenic diet reduces brain inflammation are still being elucidated. However, some potential mechanisms have been proposed:

• Reduction of Glucose Availability: When glucose availability is reduced, as in a ketogenic diet, the NADH:NAD+ ratio decreases. This ratio is important for energy metabolism, and its reduction activates a protein called CtBP, which suppresses the activity of inflammatory genes.
• Lower Blood Glucose: The ketogenic diet helps keep blood sugar levels low, which is beneficial for brain health. High blood sugar can exacerbate brain damage and impair cognition.
• Increased Adenosine Levels: As mentioned earlier, adenosine has anti-inflammatory properties and the ketogenic diet has been shown to increase adenosine levels in the brain.
• Reduction of Reactive Oxygen Species (ROS): Burning ketones instead of glucose leads to the production of fewer ROS, which are molecules that can cause inflammation and damage to the brain and other organs.
• Increased GABA and Reduced Glutamate: The ketogenic diet has been associated with increased levels of GABA, an inhibitory neurotransmitter that may have neuroprotective effects. Additionally, the ketogenic diet may help reduce glutamate toxicity, as the ketone body acetoacetate has been found to reduce glutamate levels in test tubes.
• Inhibition of the NLRP3 Inflammasome: The ketogenic diet inhibits the NLRP3 inflammasome, an immune complex that triggers an inflammatory response. By regulating this complex, the ketogenic diet may help modulate the immune system and reduce inflammation.

In conclusion, the ketogenic diet has been found to reduce inflammation in the brain, and one of the proposed mechanisms is through the increase of adenosine, a brain chemical with anti-inflammatory and pain-relieving properties. Further research is needed to fully understand the complex relationship between the ketogenic diet, adenosine, and brain inflammation.

Ketogenic diets may reduce inflammation in the brain by producing fewer reactive oxygen species (ROS), which can damage and inflame organs

The ketogenic diet is a low-carbohydrate, high-fat regimen that has been used to treat epilepsy and other neurological illnesses. Research suggests that the diet may also lower inflammation in the brain, which could be beneficial for those suffering from stroke and brain trauma.

The ketogenic diet changes the way the body uses energy. When the body is deprived of glucose derived from carbohydrates, it starts using fat as an alternative source of energy. This metabolic shift can reduce inflammation and improve outcomes after brain injury.

The ketogenic diet has been found to reduce the production of reactive oxygen species (ROS), which can damage and inflame organs. Specifically, the diet stimulates the cellular endogenous antioxidant system and increases the efficiency of the electron transport chain.

The ketogenic diet may reduce inflammation in the brain by producing fewer reactive oxygen species, which can damage and inflame organs. This can be especially beneficial for those suffering from neurological illnesses or brain injuries.

Ketogenic diets may reduce inflammation in the brain by increasing GABA, an inhibitory neurotransmitter, and reducing glutamate, an excitatory neurotransmitter

The ketogenic diet is a low-carbohydrate, high-fat diet that has been used to treat epilepsy and is being studied for its potential benefits in treating other neurological illnesses. The diet is thought to work by lowering inflammation in the brain.

The ketogenic diet changes the way the body uses energy. By reducing the amount of carbohydrates, the body is deprived of glucose, its primary source of energy, and starts using fat as an alternative source of energy. This metabolic shift causes a reduction in inflammation in the brain.

The ketogenic diet may also increase GABA, an inhibitory neurotransmitter, and reduce glutamate, an excitatory neurotransmitter. GABA is the most common inhibitory neurotransmitter in the central nervous system, and it slows down brain functions by blocking specific signals. Glutamate, on the other hand, is the main excitatory neurotransmitter, permitting the passing of chemical messages from nerve cell to nerve cell.

The balance between GABA and glutamate is crucial for a properly functioning brain. The ketogenic diet is thought to alter this balance by increasing the inhibitory effects of GABA and decreasing the excitatory effects of glutamate. This may be due to the diet's effect on intermediary metabolism, which influences the dynamics of the major inhibitory and excitatory neurotransmitter systems in the brain.

The exact mechanism by which the ketogenic diet protects against seizures is still not fully understood, and more research is needed to confirm the role of GABA and glutamate in this process.
