Ketosis and Exogenous Ketones For Brain and Neurological Health

In a discussion about ketosis and brain health, Tim Ferriss and Dominic D'Agostino explore how ketones can serve as an alternative energy source for the brain, particularly in conditions like Alzheimer's disease where glucose metabolism is compromised. D'Agostino explains that beta-hydroxybutyrate (BHB) not only provides fuel but also directly inhibits inflammation and activates cellular defense mechanisms.

The conversation reveals that ketones can reduce anxiety in ways similar to benzodiazepines, with D'Agostino noting that the optimal blood ketone range is between 1.2 and 2 mmol. This effect occurs partly through altering the balance of neurotransmitters in the brain, particularly by increasing GABA relative to glutamate.

Keto Diets & Supplements For Cancer & Chronic Diseases

D'Agostino discusses how ketogenic approaches can help fight cancer by starving cancer cells while fueling healthy ones. He explains that when combined with modern immunotherapies like checkpoint inhibitors, ketogenic therapies can enhance anti-cancer immunity and boost T-cell function.

The therapeutic potential extends beyond cancer, with D'Agostino noting that ketones can inhibit the NLRP3 inflammasome, which is linked to various age-related diseases. This mechanism has attracted significant interest from pharmaceutical companies seeking to develop drugs that mimic these effects.

Tips and Cautions For a Ketogenic Diet or Ketone Supplements

When following a ketogenic diet, D'Agostino emphasizes the importance of monitoring key biomarkers, including [restricted term] levels, hemoglobin A1c, and HSCRP. Ferriss adds his experience using the Keto Mojo device for glucose monitoring, while cautioning about potential variations between device readings and lab tests.

D'Agostino provides practical advice for optimizing ketone supplementation, suggesting that combining MCT oil with ketone supplements can produce higher and more sustained ketone levels. He recommends starting with morning fasted cardio and maintaining proper hydration and electrolyte balance to prevent "keto flu."

Ketogenic Effects on Immune, Inflammation, and Mitochondria

The discussion turns to how ketosis affects inflammation and immunity, with D'Agostino explaining that ketogenic therapies can enhance the adaptive immune system, particularly through BHB's role in suppressing inflammatory pathways.

Regarding mitochondrial health, D'Agostino shares his research on NAD and its potential benefits for conditions like Alzheimer's and fatty liver disease. He also discusses the role of supplements like CoQ10, particularly for those taking medications that might deplete CoQ10 levels, while cautioning about proper dosing based on animal studies showing potential toxicity at high levels.

  • Exogenous ketones are ketone bodies consumed through supplements or foods, providing an immediate source of ketones regardless of the body's current state of ketosis. These supplements often contain β-hydroxybutyrate (BHB), a key ketone body that can be efficiently converted into energy in the body. BHB can be utilized for energy production through conversion to acetoacetic acid, which then enters the energy pathway to generate ATP. Exogenous ketones offer a way to elevate ketone levels without the need for strict dietary changes, potentially offering benefits for brain health, energy levels, and metabolic functions.
  • Beta-hydroxybutyrate (BHB) is a type of ketone body produced in the liver during periods of fasting or low carbohydrate intake. It serves as an alternative energy source for the brain and body when glucose levels are low. BHB can have various health benefits, including providing fuel for the brain, reducing inflammation, and potentially improving conditions like Alzheimer's disease. It is a key component in ketogenic diets and supplements aimed at promoting overall health and well-being.
  • Gamma-aminobutyric acid (GABA) and glutamate are neurotransmitters in the brain that play crucial roles in regulating brain activity. GABA is an inhibitory neurotransmitter that helps calm neural activity, while glutamate is an excitatory neurotransmitter that stimulates brain function. An imbalance between GABA and glutamate levels can lead to neurological issues like anxiety, seizures, and cognitive impairments. Ketones from a ketogenic diet can influence this balance by increasing GABA levels relative to glutamate, potentially contributing to reduced anxiety and improved brain function.
  • Checkpoint inhibitors are a type of cancer immunotherapy that work by blocking proteins that prevent the immune system from attacking cancer cells. By releasing these "checkpoints," the immune system can better recognize and target cancer cells for destruction. This approach has shown significant success in treating various cancers and is often used in combination with other therapies to enhance the immune response against cancer. Checkpoint inhibitors can lead to long-lasting responses in some patients, offering a promising avenue in the field of cancer treatment.
  • The NLRP3 inflammasome is a complex involved in triggering inflammatory responses and cell death in the immune system. It is activated by various signals like pathogens or cellular damage, leading to the release of pro-inflammatory molecules and a form of cell death called pyroptosis. The NLRP3 inflammasome is part of a larger network of cell death complexes and plays a crucial role in immune responses and maintaining cellular homeostasis.
  • HSCRP, or high-sensitivity C-reactive protein, is a biomarker used to measure inflammation levels in the body. Elevated HSCRP levels are associated with various health conditions like cardiovascular disease and chronic kidney disease. Monitoring HSCRP can provide insights into the degree of inflammation present and help assess the effectiveness of treatments targeting inflammation. In the context of the text, monitoring HSCRP levels is important for evaluating the impact of a ketogenic diet or ketone supplements on inflammation and overall health.
  • Keto flu is a term used to describe a collection of symptoms that some people may experience when starting a ketogenic diet. These symptoms can include fatigue, headache, dizziness, irritability, and nausea, among others. It is believed to occur as the body adjusts to using ketones for energy instead of carbohydrates. Staying hydrated, ensuring electrolyte balance, and gradually transitioning into ketosis can help alleviate these symptoms.
  • NAD (nicotinamide adenine dinucleotide) is a coenzyme found in all living cells that plays a crucial role in various biological processes, including energy production and DNA repair. Research suggests that boosting NAD levels may have benefits for conditions like Alzheimer's disease and fatty liver disease by supporting mitochondrial function and cellular health. Supplements like CoQ10 can also complement NAD's role in maintaining mitochondrial health, especially for individuals on medications that may deplete CoQ10 levels. However, caution is advised regarding the dosage of such supplements, as high levels could potentially lead to toxicity, as indicated by animal studies.
  • Coenzyme Q10 (CoQ10) is a vital compound that plays a crucial role in producing energy in the body's cells. It acts as an antioxidant, protecting cells from damage and supporting overall cellular function. CoQ10 is naturally produced in the body and can also be obtained through dietary sources or supplements. It is involved in various processes, including supporting heart health, promoting energy production, and potentially mitigating the side effects of certain medications.
  • Coenzyme Q10 (CoQ10) is a compound that plays a crucial role in producing energy in the body's cells. While generally considered safe, high doses of CoQ10 may lead to potential side effects such as mild insomnia, elevated liver enzymes, and gastrointestinal issues.

Ketogenic Effects on Immune, Inflammation, and Mitochondria

Ketosis Suppresses Inflammation and Enhances Anti-Cancer Immunity

In the conversation, it is implied that ketosis and a ketogenic diet have anti-inflammatory effects. Dominic D’Agostino explains that ketogenic therapies modulate inflammation through the NLRP3 inflammasome. Such therapies not only impact metabolism but also have sizable anti-inflammatory effects. Elevated levels of beta-hydroxybutyrate (BHB), an endogenous [restricted term], are partly accountable for these effects, as BHB suppresses the NLRP3 inflammasome.

D'Agostino also discusses the role of ketone metabolic therapy in augmenting the adaptive immune system. This more specific part of the immune system can be likened to the "Navy Seals," contrasted with the innate immune system. He mentions a study in Nature Medicine that found a two-week ketogenic diet enhanced the adaptive immune system, partly through the gut and by altering metabolic physiology.

Fasting states and ketosis reduce inflammatory cytokines and chemokines, resulting in an immune system that is less inflammatory overall. Dr. Diptiks at Yale formulated a diet specifically to elevate BHB due to its inflammasome suppression role. D'Agostino also discusses providing ketones to his dogs for their anti-inflammatory and anti-cancer effects.

Elevated Ketones Inhibit Inflammatory Nlrp3 Pathways

Beta-hydroxybutyrate (BHB) has been found to suppress the NLRP3 inflammasome. Studies show that both fasting and BHB supplementation can suppress the inflammasome.
