For decades, we were told a story that never quite sat right.
That fat was the enemy, and that a high fat diet would harm our health. That butter, eggs, and bacon would clog our arteries. That sugar was harmless — even necessary.
But science has spent the last twenty years quietly dismantling that narrative. Today, we know that the ketogenic diet — often called the keto diet — is a high fat, very low carbohydrate diet that shares many similarities with the Atkins and other low carb diets. This high fat diet approach stands in contrast to previous low-fat dietary advice.
What we now understand is this: your brain doesn’t thrive on sugar — it thrives on fat. The ketogenic diet is characterized by high fat intake, moderate protein consumption, and low carbohydrate intake, typically around 70-80% fat, 10-20% protein, and 5-10% carbohydrates. Unlike the 2015 – 2020 Dietary Guidelines for Americans, which recommend 20-35% of calories from fat per day, the ketogenic diet typically consists of 70-80% fat, making it a strict eating pattern high in fat, moderate in protein, and low in carbohydrates.
Low-carbohydrate and ketogenic approaches, including very low carbohydrate diets, have consistently shown health benefits for fat loss, metabolic health, appetite regulation, and insulin sensitivity. A meta-analysis of 13 studies found that following a very low carb, ketogenic diet was slightly more effective for long-term weight loss than a low fat diet. And despite the fear-based messaging around fat, long-term data does not show an increased risk to cardiovascular health when keto is done correctly. In fact, many markers improve. For comparison, the Mediterranean diet is also known for its health benefits, particularly for cardiovascular and metabolic health, but it emphasizes plant-based foods and healthy fats rather than the high fat intake of a ketogenic diet.
This matters — because the brain is the most energy-hungry organ in your body.
It makes up only 2% of your body weight, yet consumes around 20% of your daily energy. And unlike muscles or the liver, the brain cannot store fuel. It is entirely dependent on what you give it.
Glucose can power the brain short-term — but at a cost.
Over time, a high-carbohydrate, high-sugar diet drives insulin resistance in brain cells. Insulin is the hormone that escorts glucose into the cell. When neurons stop responding to insulin, glucose can’t get in — even though blood sugar is high.
So the brain begins to starve… in a body flooded with fuel.
Add in modern stressors — processed seed oils, chemical additives, GMOs, heavy metals, halogens — and this dysfunction accelerates. Mitochondria falter. Inflammation rises. Detox pathways slow.
This metabolic paradox is now referred to as “Type 3 Diabetes.”
As energy production collapses, neurons deteriorate. Toxic proteins like beta-amyloid and tau accumulate. Communication between brain cells breaks down.
What we call dementia isn’t random. It’s metabolic failure.
Why Ketosis Changes Everything
When carbohydrates are restricted, the body shifts gears into a state known as nutritional ketosis. In this metabolic state, the liver converts fatty acids into ketone bodies—including acetoacetate, beta-hydroxybutyrate, and acetone—which serve as alternative energy sources for the brain and other organs. To achieve ketosis, carbohydrate intake should be limited to around 20 to 50 grams per day.
Instead of relying on sugar, the liver begins converting fat into ketones—a clean, efficient, high-octane fuel that crosses the blood–brain barrier with ease. The ketogenic diet works by forcing the body to burn fats rather than carbohydrates for energy, and is characterized by a significant reduction in carbohydrate intake, leading to decreased insulin levels and increased fat breakdown.
Ketones don’t just feed the brain.
They heal it.
They improve mitochondrial efficiency, reduce oxidative stress, calm inflammation, and restore metabolic flexibility—even when glucose pathways are damaged. Ketone bodies are especially important as an alternative energy source for the brain and other organs during periods of low carbohydrate intake.
This is why the ketogenic diet was originally developed to treat epilepsy, specifically pediatric epilepsy. The ketogenic diet was first used as a treatment for pediatric drug-resistant epilepsy in the 1920s and is still prescribed for seizures in the United States when medications are ineffective and other treatments are not an option. Reports of the ketogenic diet's efficacy for epilepsy treatment have proven consistent across all age groups, seizure frequencies, and locations, with around half of children and young people with epilepsy who have tried the ketogenic diet seeing the number of seizures drop by at least half.
The ketogenic diet is indicated as an adjunctive treatment in children and young people with drug-resistant epilepsy, and it has regained attention through numerous studies showcasing its effectiveness in patients with drug-resistant epilepsy and certain pediatric epilepsy syndromes. The ketogenic diet is also being investigated as a treatment for various neurological disorders, including Parkinson's disease, Alzheimer's disease, hypercholesterolemia, autism, and depression.
The ketogenic diet was developed to reproduce the success of fasting in treating epilepsy and has been shown to have antiepileptogenic properties in animal models.
Ketosis supports:
-
Improved insulin sensitivity
-
Stable blood sugar
-
Reduced appetite
-
Enhanced mental clarity
-
Protection against neurodegeneration
And importantly—it gives the brain an alternative fuel source when sugar can no longer do the job.
It is also important to moderate protein intake on a ketogenic diet, as excessive protein can be converted into glucose via amino acids through gluconeogenesis, which may interfere with maintaining ketosis.
Understanding Alzheimer's Disease and Dementia Through a Metabolic Lens
Dementia is not one disease. It’s an umbrella term for multiple neurological conditions — with Alzheimer's disease being the most common form of dementia — that share overlapping metabolic dysfunction.
Risk factors include:
-
Insulin resistance and diabetes
-
Cardiovascular disease
-
High blood pressure
-
Obesity
-
Chronic inflammation
-
Toxic burden
-
Thyroid dysfunction
For years, a low fat diet was prescribed as protective. We now know that this advice may have unintentionally deprived the brain of the very fuel it needs to survive.
Ketogenic and low carbohydrate diet approaches are showing promise not just for those looking to lose weight, but also for cognitive preservation and supporting metabolic health in various body tissues, such as the brain, heart, and muscles. The ketogenic diet is particularly effective for weight loss in obese adults, and studies show it can lead to significant reductions in blood sugar and insulin levels. Individuals with type 2 diabetes following a ketogenic diet may experience improved blood sugar management and weight loss. Additionally, the ketogenic diet can lead to a decrease in hunger, making it easier to lose weight without counting calories, and can improve metabolic health by reducing triglycerides and increasing HDL cholesterol levels.
It’s important to note that while a ketogenic diet is a very low carbohydrate diet (restricting carbohydrate intake to less than 50 grams per day and inducing ketosis), a broader low carbohydrate diet involves reducing carbohydrate intake without necessarily reaching ketosis. A meta-analysis of 13 studies found that individuals on a very low-carbohydrate ketogenic diet achieved greater long-term weight loss compared to those on a low fat diet.
That said, keto is not one-size-fits-all.
For individuals with compromised liver function, cardiovascular challenges, or blood pressure concerns, a modified approach — using fasting, ketone support, and higher protein with lower carbohydrate intake — may be more appropriate.
The goal is not dietary dogma. The goal is metabolic flexibility and brain resilience.
What’s Really Breaking Down in Cognitive Decline and Cognitive Impairment
Cognitive decline is never caused by a single failure. It’s a cascade:
-
Insulin resistance in the brain blocks glucose uptake
-
Mitochondrial dysfunction reduces ATP production
-
Oxidative stress and inflammation damage neurons
-
Toxic accumulation disrupts signaling
-
Nutrient deficiencies impair repair and neurotransmission
A high fat ketogenic diet, often referred to as a fat diet, addresses these failures at the root by shifting the body’s primary fuel source from carbohydrates to fats. This dietary approach emphasizes increased fat consumption, which supports brain health and metabolic function. The ketogenic diet is characterized by high fat, moderate protein, and low carbohydrate intake, and it works by forcing the body to burn fats rather than carbohydrates for energy.
Ketosis addresses these failures at the root — but only if the supporting systems are functioning.
Low Glycemic Index Treatment and Glycemic Control
While the ketogenic diet and other very low carbohydrate diets have gained attention for their role in supporting cognitive function and metabolic health, the Low Glycemic Index Treatment (LGIT) offers a gentler, more balanced approach for those seeking sustainable results. LGIT focuses on limiting carbohydrate intake to foods with a low glycemic index—meaning they have a minimal impact on blood sugar levels. This strategy helps to stabilize blood sugar, reduce insulin resistance, and address key cardiovascular risk factors that contribute to cognitive decline and dementia.
Research suggests that LGIT is particularly effective for individuals who find strict low carb diets or the Modified Atkins Diet too restrictive. By allowing a moderate intake of carbohydrates—provided they are low glycemic—LGIT supports long-term adherence, making it easier to achieve significant weight loss and maintain healthy body weight. This is crucial, as excess body fat and high blood sugar are well-established risk factors for developing dementia, including vascular dementia and mixed dementia.
A systematic review of randomized controlled trials has shown that LGIT can lead to meaningful improvements in glycemic control, such as lower HbA1c levels and enhanced insulin sensitivity. These changes not only support disease control in type 2 diabetes but also reduce the risk of cardiovascular disease and high blood pressure—both of which are linked to cognitive impairment and dementia symptoms.
Importantly, LGIT’s benefits extend beyond metabolic health. Clinical nutrition studies have found that this approach can improve cognitive function and reduce dementia symptoms in individuals with Alzheimer’s disease and Lewy body dementia. By minimizing spikes in blood sugar and supporting improved insulin sensitivity, LGIT helps protect nerve cells from the damaging effects of high blood sugar and insulin resistance—two major contributors to neurological disorders.
For those concerned about developing dementia or managing existing neurological conditions, LGIT provides a practical, research-backed option. It supports cardiovascular health, promotes significant weight loss, and helps maintain stable blood sugar—all while offering a more flexible meal plan than stricter low carb diets. By focusing on low glycemic foods, individuals can enjoy a healthy diet that supports both body and brain, reducing the risk of cognitive decline and supporting healthy aging.
Why Keto Alone Isn’t Enough
This is where most people get stuck.
- A sluggish thyroid blunts fat metabolism.
- A congested liver stalls ketone production.
- Heavy metals and halogens block iodine and mitochondrial enzymes.
So while keto sets the stage, the body still needs support to perform. Mineral supplements are especially important for individuals on a ketogenic diet, as they help maintain electrolyte balance and prevent side effects like the keto flu that can result from water and mineral imbalances.
It's also important to note that the ketogenic diet is not safe for individuals with certain medical conditions involving their pancreas, liver, thyroid, or for those with a history of eating disorders. Consulting a healthcare professional before starting a ketogenic diet is crucial, especially for those with underlying conditions like diabetes or kidney disease.
This is where targeted supplementation changes outcomes.

The Synergy That Rebuilds the Brain
This is not about doing keto harder. It’s about doing it intelligently.
Fasting clears damaged cells, and intermittent fasting can help accelerate the process of entering ketosis.
Iodine and thyroid support ignite metabolism. Methylene blue powers the mitochondria. Cogniblast refines communication and neuroplasticity.
Eating behavior plays a crucial role in diet adherence and therapeutic outcomes, influencing how well you maintain a ketogenic diet and achieve metabolic benefits.
To optimize your ketogenic diet, include foods like meat, fish, eggs, butter, nuts, healthy oils, avocados, and low-carb vegetables, while avoiding grains, sugars, legumes, rice, potatoes, candy, juice, and most fruits.
Suitable snacks for a ketogenic diet include pieces of meat, cheese, olives, boiled eggs, nuts, raw veggies, and dark chocolate.
When dining out, choose meat, fish, or egg-based dishes and replace high-carb sides with extra vegetables.
The result is restored energy, detoxification, and regeneration — the three pillars of brain health.
The Bottom Line
Dementia and cognitive decline are not inevitable.
They are metabolic breakdowns.
And metabolic problems require metabolic solutions.
When you combine a clean ketogenic or low-carbohydrate lifestyle with targeted mitochondrial, thyroid, and detox support, you’re not just changing what you eat — you’re changing how your brain fuels, heals, and functions.
Because longevity isn’t about adding years to life.
It’s about protecting clarity, connection, and vitality — every step of the way.
