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.
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.
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."
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.
1-Page Summary
Research suggests that ketosis, whether through diet or the use of exogenous ketones, has potential benefits for brain and neurological health, especially in the context of neurodegenerative and psychiatric disorders.
Ketones serve as an alternative energy source for the brain in conditions like Alzheimer's disease, which is sometimes likened to type 3 diabetes due to its association with glucose metabolism issues. Tim Ferriss, having a personal stake in the matter due to his family history and genetic predisposition (APOE34), explores the potential of ketones to mitigate problems in neurodegenerative diseases when normal pathways like glucose metabolism fail.
Dominic D’Agostino elaborates on the therapeutic potential of beta-hydroxybutyrate (BHB), referencing a case where the ketone was used for Alzheimer's symptoms. A paper from colleagues at Yale showed that ketones directly inhibit inflammation independent of their role as metabolic fuel. BHB, in particular, is noted to inhibit HDAC class 1 and class 2, which can activate the body’s antioxidant and cellular defense mechanisms.
Further evidence of the benefits of ketosis is demonstrated in animal studies where ketone supplementation has shown anxiolytic effects similar to benzodiazepine. Additionally, inducing acute ketosis through exogenous ketone formulations increased exploratory behavior in the elevated plus maze.
D’Agostino and Ferriss discuss that the "Goldilocks amount" of ketones (1.2 to 2 mmol range in blood) can reduce anxiety. However, overly high levels from exogenous ketones might cause increased anxiety followed by a ...
Ketosis and Exogenous Ketones For Brain and Neurological Health
Dominic D’Agostino discusses the effectiveness of ketone metabolic therapy and ketogenic diets in the treatment and management of cancer and chronic diseases, underscoring the benefits of maintaining a favorable glucose ketone index through these diets.
D’Agostino advises cancer patients to incorporate sources of omega-3 fatty acids, such as sardines, instead of a water-only fast, to prevent cancer cachexia. He explains that by creating a caloric deficit, one can suppress [restricted term] Mtor, activate AMP kinase, and support autophagy processes.
D’Agostino expresses that the wide-ranging mechanisms of ketogenic therapies have pleiotropic effects, meaning they produce multiple beneficial outcomes. He highlights a publication that illustrates how ketogenic therapies can modulate the NLRP3 inflammasome. This discovery has attracted pharmaceutical companies interested in developing drugs that mimic such effects.
In collaboration with the Moffitt Cancer Center, D’Agostino is involved in studies using ketone metabolic therapy to augment immune therapy. This therapy includes the use of beta-hydroxybutyrate to activate the adaptive immune system, thereby enhancing the effectiveness of checkpoint inhibitors—a class of drug used in immune therapy. He notes that ketones can also expand T cells associated with CAR-T therapy and boost cancer-specific immunity that is augmented by PD-1 inhibitors.
D’Agostino mentions the brain-boo ...
Keto Diets & Supplements For Cancer & Chronic Diseases
Dominic D'Agostino and Tim Ferriss discuss the growing interest in ketogenic diets and ketone supplements, offering insights into metabolic monitoring and providing guidance on using supplements safely.
D'Agostino highlights the importance of monitoring key health biomarkers for individuals on a ketogenic diet. He suggests looking at [restricted term] levels, hemoglobin A1c, and HSCRP (high-sensitivity C-reactive protein) to assess overall cardiometabolic health. Tim Ferriss mentions using a Keto Mojo device to measure his glucose level and the value of testing hemoglobin A1c as a metabolic biomarker, cautioning that device readings can trend higher than laboratory tests.
Ferriss discusses potential risks associated with common ketone supplements, particularly liver toxicity with long-term use of certain types. He references conversations about moving away from using 1,3-butanediol and 1,3-butanediol-based ketone esters due to these potential effects. D'Agostino adds that when ketone levels get very high, anxiogenic effects can occur, implying a need for caution with chronic usage.
D'Agostino shares that exogenous beta-hydroxybutyrate (BHB) combined with MCT oil can produce higher BHB levels than either supplement alone. Additionally, MCT oil can sustain the elevation of BHB salts and esters by slowing absorption, making them a recommended pairing.
To ease the transition into ketosis, D'Agostino proposes doing fasted low-intensity cardio in the morning and staying well hydrated, taking MCT oil, and ketone electrolytes. He explains that upregulating ketolytic enzymes takes some ti ...
Tips and Cautions For a Ketogenic Diet or Ketone Supplements
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.
Beta-hydroxybutyrate (BHB) has been found to suppress the NLRP3 inflammasome. Studies show that both fasting and BHB supplementation can suppress the inflammasome.
Ketogenic formulations are known to support mitochondrial health, which is particularly beneficial for conditions related to neurodegeneration and aging. Dominic D'Agostino focuses on how ketones, specifically D and L beta-hydroxybutyrate, are beneficial for mitochondrial health.
D’Agostino is engaged in research on NAD, including injectables, in the context of Alzheimer's and other diseases. He believes that long-term use of NAD could enhance markers of mitochondrial health, particularly in conditions like non-alcoholic fatty liver disease or Alzheimer's. NAD is essential for numerous metabolic enzymes, sirtuins, and DNA repair.
An imbalance of the NAD to NADH ra ...
