Getting Enough Omega-3 Fatty Acids on a Keto Diet


 Teaching at the University of South Florida, Dominic D’Agostino has a research focus on ketone supplementation and ketone ester, and the effect of a ketogenic diet on metabolism and muscle growth. One area that Dominic D’Agostino explored in a KetoNutrition article is how a keto diet affects one’s omega-3 fatty acid intake.


As a meat eater following a keto diet, the arithmetic is relatively simple: two or three servings of fatty fish each week should fulfill one’s docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) requirements. Both DHA and EPA are omega-3s that have been linked to a variety of positive health outcomes.


As a vegan, obtaining omega-3s is more challenging. Those who make the effort to eat walnuts, flax seeds, and chia on a regular basis may feel that that they have all the bases covered. Unfortunately, these foods are only rich in the omega-3 fatty acid alpha linolenic acid (ALA), which is a precursor to the even more vital DHA and EPA. While there is a slow enzymatic process by which the body does complete the conversion to the desirable omega-3, it would take large quantities of such foods to produce a sufficient quantity.


One plant-based solution is to eat microalgae in an accessible form such as the spirulina tablet ENERGYbits. Similar microalgae are consumed by fish such as sardines and salmon, who then store the DHA and EPA as fat.

A Plant-Based Pathway for a Ketogenic Diet


 Dominic D’Agostino is a University of South Florida associate professor who undertakes clinical research in areas such as ketone ester and supplementation, and muscle performance. One of Dominic D’Agostino’s areas of expertise is a plant-based approach to a ketogenic diet, which is detailed on the KetoNutrition website.


While most people associate a keto lifestyle with abundant meat consumption, this is not necessarily the case. The classic strict 4:1 ketogenic diet has caloric intake of 90 percent fat, 6 to 10 percent protein, and 2 to 4 percent carbs. This makes significant vegetable consumption a challenge. However, today’s modified versions of the keto diet are more lenient, with 65 to 85 percent of daily calories derived from fat, 15 to 35 percent from protein, and as much as 10 percent from carbs.


A sustainable vegan keto diet is possible with this configuration. It starts with removing or severely limiting all legumes, grains, and fruit. Without the fat that meat and dairy provide, make healthy oils such as those from coconut, walnut, and avocado an integral part of your daily diet. At the same time, remove all root vegetables from the diet, such as beets or potatoes, as they are not fibrous and are typically high in carbohydrates. Once an ideal diet is in place, carefully track the macronutrient ratios (not calories) required for sustaining nutritional ketosis.

How Ketone Bodies Fuel Muscle Adaptation


 Instructing at the University of South Florida, Dominic D’Agostino is a professor who pursues basic science research and clinical applications of ketone ester supplementation, ketone salts and related ketone technologies. A particular area of interest for Dominic D’Agostino is muscle function and its pivotal role in augmenting performance and overall metabolic health. When a body goes into ketogenesis under carb-restricted dietary conditions, ketone bodies such as beta-hydroxybutyrate (BHB), acetoacetate (AcAc), and acetone are generated by the liver and provide a energetic reserve and important tissue signaling functions.


During exercise, the muscles no longer primarily rely on glycogen (high intensity workout) or lipids and muscle protein amino acids (low intensity workout) for generating the fuel adenosine triphosphate (ATP). Rather, ketone bodies are gradually employed by working muscles as fuel, with the capacity to oxidize the ketone bodies for energy increasing as muscle is trained. Part of being in a keto-adapted state is the increases levels of ketogenesis, ketone transport and tissue ketone utilization (ketolysis).


Beyond this muscle-fueling purpose, ketone bodies serve as signaling molecules for regulating the body’s gene expression and adaptive responses to energetic stress and exercise intervention. One study demonstrated that ketone BHB offers a shield against oxidative stress. It prevents the accumulation of intramuscular fat and decreases muscle wasting, while boosting oxidative metabolism as one ages. In tandem with this, BHB was shown to upregulate the genes associated with muscle atrophy and reduce anabolic gene expression. In this context the elevation of ketones helps to spare energy reserves. Ultimately, it is shown that the ketogenic diet has different effects on skeletal muscle that are partially explained by muscle fiber type, while the ketogenic diet can lead to a change in the fiber type ratio in the muscle itself. While currently the data is contradictory on the ketogenic diet’s benefits and adverse effects on muscle tissue, there is still room for discovery to be made in how the ketogenic diet impacts muscle metabolism in states outside of prolonged fasting and starvation. Based upon what we know about the anti-catabolic effects of ketones, and their multifunctional role during starvation, the benefits of being in ketosis appear to have the greatest effect during metabolic stress associated with disease states and exercise-induced stress. In this context the ketone-induced effects are protective and may confer a longevity advantage when it comes to longevity and long term preservation of muscle structure and function.

Continuous Glucose Monitors Enhance Education of Medical Students


 Teaching at the University of South Florida at the Morsani College of Medicine and performing research in ketogenic diet and ketone supplementation, Dominic D'Agostino possesses extensive knowledge on exogenous ketone supplementation and ketone technologies that help muscle performance and resilience. Dominic D'Agostino follows the latest findings in his field, including an American Journal of Lifestyle Medicine report on a pilot metabolic immersion program that employed continuous glucose monitors (CGMs) in medical students as part of a "metabolic immersion" program to enhance awareness and best practices within metabolic medicine and diabetes management.


The study involved 13 healthy students at Harvard Medical and Dental training on CGMs while being screened for underlying health issues. The students used the CGMs for 30 to 40 days while their dietary intake was tracked, in addition to a number of other variables that would help to assess the utility of CGMs for medical training.


Questionnaires revealed that participants felt the CGMs provided important insights into how the body reacts to food intake and aided with their medical education. In particular, CGMs made them more aware of how they could assist patients with diabetes battling elevated glucose levels. The CGM also encouraged them to alter their eating habits. Such devices, which encourage lifestyle modification and nutrition, may also inform the choices of those who opt for a low-glucose/ low carbohydrate ketogenic diet.

New Research Links Ketogenic Diet to Gut Microbiome, Neurologic Health

 

An accomplished scientist and associate professor at the University of South Florida, Dr. Dominic D’Agostino researches ways of improving human neurology and physiology through the ketogenic diet. Dominic D’Agostino has broad knowledge of ketone esters, ketone supplementation, and ketone technologies. He shares his knowledge on KetoNutrition.org. One of his recent articles is on the gut-brain axis (GBA).

The gut-brain axis (GBA) refers to the physiological highway connecting the brain’s central nervous system (CNS) with the enteric nervous system (ENS) in the intestines. The ENS is responsible for body functions that do not require thinking about like digesting food, breathing, and circulating blood. The vagus nerve is the physiological highway between these two systems.

Information flow along the vagus nerve is two-way. The brain communicates its needs to the gut through the vagus nerve while the gut microbiome in the ENS produces key neurotransmitters that travel to the brain and eventually regulate neurologic, metabolic, and immune functions. A healthy gut microbiome, therefore, is essential to overall wellness.

The health of the gut microbiome is influenced by a number of things, key among them diet. Emerging research points to the benefits of a ketogenic diet to the gut microbiome and neurological health. Research on children with epilepsy has shown that a ketogenic diet improves regulation of immune factors central to controlling seizures. Additional research has linked the ketogenic diet to enhanced mental health. Specifically, when ketones become the brain’s primary source of energy, as is the case in a ketogenic diet, levels of the calming neurotransmitter GABA increase while those of the excitatory neurotransmitter glutamate fall. The diet further elevates adenosine levels, which also contributes to neurologic health.

Keto and Cancer - Understanding KMT



Dominic D’Agostino, PhD, is a research scientist investigating the science and application of the ketogenic diet and exogenous ketones, sometimes referred to more generally as "nutritional ketosis". The use of exogenous ketones in the form of ketone esters and ketone salt supplementation is also a significant part of his research efforts.. An associate professor at the University of South Florida, Morsani College of Medicine in Tampa, Dr. Dominic D’Agostino produces a KetoNutrition newsletter, where he covers topics such as application of the keto diet and ketogenic metabolic therapy (KMT).

Metabolic-based therapies, including KMT, shifts metabolic physiology and brain energy metabolism to manage verious disease processes and to strengthen resistance to illnesses. The application of KMT uses a well formulated keto diet as a base therapy, specialized supplements, and in some cases drugs. Published research and trials on clinicaltrials.gov show that many researchers are exploring how the ketogenic diet and KMT (additional things that enhance ketosis) can fight cancers that thrive on glucose and glutamine, including breast cancer.

Studies indicate that a healthy and well-balanced diet can reduce cancer risk, and this is primarily due to improving various metabolic biomarkers like blood glucose, insulin, triglycerides and reducing overall body weight.. In fact, proponents claim that alternative diets stimulate metabolism and boost the immune system to fight cancer. Specifically, diet therapy can enhance cancer-specific immune regulation through physiological changes.

Notably, there is growing evidence on how KMT affects cancer cells through pleiotropic effects. It works by reducing insulin secretion and glucose transport into tumor cells. At the same time, it increases fat burning effects and ketone body production, a metabolic fuel that nourishes healthy cells but has direct anti-cancer effects.. Together with glutamine targeting (EGCG and Theanine), emerging evidence demonstrates that KMT can target tumor cells and reduce inflammation without injuring surrounding healthy tissue. In addition, the ketone supplementation with ketone esters or exogenous ketone salts (KetoStart) can further enhance KMT by improving (lowering) the Glucose/Ketone Index (GKI).

Winning the Fight Against Neurogenerative




Since June of 2006, Dominic D’Agostino, PhD, has served as an associate professor at Tampa’s University of South Florida. In addition to his ketone research, Dr. Dominic D’Agostino supports the organization Winning the Fight. The nonprofit performs research and provides support for patients with neurodegenerative diseases and their loved ones.

Neurodegenerative diseases degrade the health and functioning of a patient’s central nervous system over time. Conditions of this type do not currently have cures, but treatments exist that can slow, or even stop, their progression.

Winning the Fight’s Deanna Protocol (DP) is a regimen of supplements that compensates for the lack of certain chemicals in ALS {Lou Gehrig’s Disease) patients’ nerve cells. When a nerve cell dies, it releases glutamate, a neurotransmitter that kills the cells around it, accelerating ALS’ progression. The DP Plan is an inexpensive way to extend nerve cells’ lifespans without the side effects of well-known ALS drugs. Patients can utilize the DP Plan by itself, or alongside other treatments.

To begin the DP Plan, patients register on Winning the Fight’s website. They then take a survey that evaluates the progression of their condition. Once approved, they not only gain access to the physical supplements, but also to an online community for patients and their loved ones with shared experiences.
