Ketogenic Diet Alzheimer: Does Keto Diet Cure Alzheimer’s Disease?

Ketogenic Diet Alzheimer

The ketogenic diet is a viral health program that people practice to improve their quality of life. Also, this diet plan does not only help you to avoid your unhealthy eating habits and lose weight, but actually, keto is much more than that.


It is one of the diets that have been thoroughly studied. It has many researches related to it. It was first introduced as a treatment for epilepsy. Conclusion this brain disorder gives the scientist and medical workers the approach that this diet plan has much potential and effectiveness on the human body. So, Alzheimer’s is another brain disorder that has also been related to the ketogenic diet over the past years. So, this article gives you brief and elaborated information about this relationship between the disease and diet plan.

What is Alzheimer’s?

Alzheimer’s is a neurologic disease that influences the brain cells to shrink, which is commonly known as atrophy, and as a result of this shrinkage, the brain cells start to die, and ultimately the brain stopped to do its functioning. It is an irreversible and progressive disease that proceeds slowly over time, and usually, a person diagnosed with this brain condition in the late 50s or 60s, mainly in old age. Alzheimer’s disease is characterized by the symptoms of dementia and amnesia, which are the terms that symbolize memory loss, difficulty in thinking and remembering, and destroying thinking skills.

Even though Alzheimer’s is a brain disease, but it originates in your liver. The liver has a function of clearing out something called amyloid b plaques, so the liver usually clears this out, so it does not spread into other parts of your body, but when the liver is compromised, and it cannot do that whether it is a fatty liver or has some inflammation, . whatever the liver is going through to have a tough time getting rid of that plaquing. So it starts to develop in the brain.

But you will not be able to detect for another 20 years, then you will face dementia, so it is a process that occurs gradually and not all of a sudden.


Ketogenic Diet and Alzheimer Disease

The ketogenic diet is a high-fat and low-carb program that helps people with health problems such as obesity, high blood sugar levels, . This diet plan stimulates the ketosis metabolic process in the human body, which produces ketone bodies as a source of energy. We are not consuming enough carbohydrates that can perform glucose metabolism. The ketosis process used eth stored fat in the body, and the fact that you are consuming through the diet produces ketones bodies which act as the fuel for the brain and body so that they can work in harmony and perfection.

The keto diet was introduced in the 1920s as a treatment for epilepsy, a brain disorder, and the physician concluded that having a high-fat diet can help with better brain functions to treat epilepsy. This discovery makes the medical researchers think that if the keto diet is good for epilepsy, it can also be effective in other brain disorders and out of which Alzheimer stands out the most.

“A recent 2019 health study concluded that ketogenic diet helps to reduce amyloid plaque and may reverse the neurotoxicity caused by it and the high-carbs diets may contribute to Alzheimer disease. So, the carbohydrate restriction can be effective in the management of Alzheimer.”

This study indicates that the keto diet is way beneficial for Alzheimer’s than a high-carb diet. And it also portrays the correlation between these two subjective of a disease and a diet plan.


Also, the keto diet contains natural, organic, and 100 % grass-fed foods, which includes a ton of healthy nutrients, vitamins, and minerals with anti0infalmmontry and repairing properties that also contribute to the treatment of Alzheimer disease along with the ketone benefits.

The keto diet also eliminates gut fungi, contributing to the positive results of betterment in brain disorders. Furthermore, the presence of ketones in the body has a neuro-protective impact on the brain’s aging cell, reducing inflammation and autophagy, which results in fewer neurologic diseases such as Alzheimer’s, as concluded by the national institute of aging.

Ketogenic Diet and Dementia

Dementia is a brain disorder in which the brain’s cognitive function, which includes thinking, remembering, reasoning, and focusing, gets weakened, and you start to lose them. It is not mainly a disease. It is more of a term that describes the impaired and unbalanced functions of the brain. It usually occurs in old age when the brain cells die due to inflammation or some other reason. Dementia is also a significant symptom of Alzheimer’s disease.

Ketones have very positive effects on brain functions, as we know from all the medical and scientific researches. For example, the ketogenic diet helps with reducing brain cell death and improves the reproduction of neurons which contributes to treating dementia.

The two significant reasons that people adopt a keto diet are weight loss and enhancing brain functioning. As these are two fields, in which eth most success and researches have happened. The keto diet is not only good for dementia or Alzheimer’s, but it is also effective for memory loss, brain injury, head trauma, brain cancer, .

So, the ketogenic diet and dementia have a very positive and effective correlation which helps the patients recover and healthier faster.

Brain Favors Ketones more than Glucose. Why?

It has been known for a long time through different brain researches that it can use ketones to fulfill large portions of energy fuel that it needs, as in the keto diet, your liver produces ketones from the stored fat and the fat you eat. Scientific studies have shown that you can treat impaired and unbalanced brain functions by increasing the number of ketone bodies in the body, achievable through the keto diet.

The best and powerful way to alter brain chemistry is through food because that is where the brain chemicals come from in the first run. However, the mechanism of ketones on the brain is still under study. Still, eth review studies of 2020 and 2018 suggested that brain functions get unbalanced due to glucose metabolism, whereas the ketone productions keep them balanced and improved.

Also, insulin resistance in the brain causes a reduction in eth uptake of glucose to be used as an energy source which can cause Alzheimer’s disease, especially in a person with type 2 diabetes, POCs, mild cognitive impairment issues, . It shows that people with Alzheimer’s do better with ketones metabolism than glucose metabolism.

The Scientific Study of Ketogenic Diet and Alzheimer

Following are some of the scientific studies and quotes that further shows how the keto diet is beneficial and effective for Alzheimer disease:

  • A 2012 health study in which adults with cognitive impairment were assigned to a high-fat keto diet. So, as a result, they lose weight and better memory results, particularly in adults with higher blood ketone levels.
  • In 2015, a particular health study was conducted in which they find out the relation between higher ketone levels in the body and brain cell deaths. So, in conclusion, they found that ketones are beneficial to regenerate brain cells and lowering the number of cell deaths.
  • In 2016, some scientific researchers conducted a study on the effect of a keto diet on dementia and related brain conditions. As a result, they found out that there is a significant improvement in better memory. These thinking skills concluded the keto diet has a positive impact on the brain’s abnormal conditions.
  • In 2017, some medical researchers published experimenting with the keto diet on patients with mild and moderate Alzheimer’s disease. As a result, they found significant improvements, and once they stopped the diet plan, the gains were not there anymore.

Many similar studies have been conducted over the years, and the one thing they have in common is positive results, and not a single one ever quoted that ketone is dangerous for brain functions.


Ketogenic Diet Alzheimer Preventions

the problem is that people are waiting until they get a symptom before they do anything about it, but it is essential to take care of the liver if you want to prevent Alzheimer’s. Following are the preventions that you can do to avoid this brain disorder or even if you have the first symptoms of Alzheimer that is, dementia. Hence, the best thing is to support your liver immediately, so these things will help you to do that:

Bile salts:

Bile salts perform a significant function in decreasing amyloid plaquing and amyloid clearing in the hippocampus, which is the brain part that relies on your database or remembering certain things, . Also, a low-fat diet dries up the bile salts in the gut, so it is essential to manage the body’s bile salts and adapt to a high-fat diet like keto.

Vitamin D:

Vitamin D is essential for the liver, and it is a place where the vitamin gets s activated and stored. Vitamin D also contributes to the clearance of amyloid plaque. So, it is very good to include vitamin D dietary supplements or rich food sources in the diet to prevent Alzheimer’s. The best source of Vitamin D is sun, it is one of the best practices to walk in the morning sun to get maximum vitamin D.

Intermittent fasting:

When you do intermittent fasting helps to clear out amyloid plaquing as the body starts autophagy which is the recycling of the proteins you do not need. So intermittent fasting and the keto diet go very well together.

Doctor consultation:

As Alzheimer’s is a severe neurologic disorder, it is essential to consult your doctor before doing anything to guide you perfectly. Another important thing is that you have to take medications or whatever your doctors prescribe, as doing only the keto diet will help you. Still, medications will make the process much faster.


The ketogenic diet and Alzheimer’s correlation is a widespread phenomenon under a lot of medical studies that concluded that this diet plan is beneficial for this progressive neurologic disorder as it improves the symptoms and helps the patient recover from it quickly.
