Keto Diet Memory Loss: Does Keto Diet Aid Recovery of Memory Loss?

Keto Diet Memory Loss

Diet plans are considered to be the healthiest way of losing weight or to manage other health diseases such as diabetes and, etc. The common mistake that people usually made is that they start to make assumptions about a particular diet without consulting with their doctor or dietitian. Likewise, it is considered that the keto diet can cause memory loss and the dieters assume that this diet plan is a good idea to adopt which is extremely wrong and we will prove it in this article. In fact, keto diet memory loss is a myth and keto genic diet actually cures many brain related illnesses.


The assumption that is keto diet does not cause memory loss is concluded by many studies that it is good for brain functions and related problems including memory loss, the facts and reasons are discussed below.

What is the Ketogenic Diet?

Keto is a type of healthy diet in which you need to consume macronutrients such as proteins, carbs, and fats in a specific percentage I.e., high in fat, low in carbs, and moderate in proteins, this nutrient proportions initiate the metabolic process of ketosis. This metabolic process uses fat as the main source of energy for the body when carbs are inadequate which causes health benefits to a person like weight loss, balanced sugar levels, reduced risk of heart problems, etc.

In this diet plan, the thing that you have to focus on are the foods you are eating and also in what portions. The foods that you include in a keto diet are usually natural, organic, and 100% grass-fed and the foods that you have to exclude are majorly sugary, refined, and processed items, and all other ready-made and artificial options.



The main aim of the diet is to burn the extra fat of the body so that you can have better health status and a good lifestyle.

A Background of Keto Diet

People think that keto is a diet plan formulated by a dietitian for weight loss but the history of this diet plan is quite different. The keto diet was first introduced in the 1920s by a physician for the treatment of epilepsy disease because back in the days, there was no medicine drug available for the disease so the doctors tried different methods in which the keto diet was a successful one.

Epilepsy is a brain disorder that is characterized by seizures that occurs due to disturbance in the electrical behavior of the brain. The scientists found out that a diet high in fats can fuel the brain and reduce the symptoms of epilepsy as this diet reduce the production of glutamate and optimize the synthesis of GABA, making the seizures occur less.

The high-fat diet which is known as the keto diet now not only causes stabilization in the brain functions but also reduces inflammation, better memory, enhanced brain activity which help the physician control the disease of epilepsy in patients.

Why Brain Functions Better in Ketones Rather than Carbs?

The brain likes ketones more as proven by much scientific evidence; it has been concluded that the brain can use ketones as fuel in a much larger portion than carbs. The ketones are formed by the liver through the fat we consume in our diet or the extra fat in the body.

That is the reason, physicians and dietitians mostly recommend high-fat diet plans to people with impaired brain functions. Researches have shown that ketones can help in various brain diseases such as brain cancer, migraines, headaches, depression, epilepsy, brain injury and, etc. The actual mechanism of ketones on the brain is still under study, but a 2012 review study has shown that ketones increase nerve cell growth, strengthen nerve synapses and lessen brain inflammation.

A very interesting 2020 health study suggests that ketone stabilizes brain nerve function while carbs unbalance the nerve connection which clearly shows the reason why the brain likes ketone more than glucose as energy fuel.

What is Brain Fog and does Keto Cause it?

Brain fog is not a medical disease or condition, it is just a term that explains certain symptoms like feeling confused, blurred vision, would not be able to think or focus, and mental fatigue.


When you start a keto diet, it takes some days for your body to get adapted to the change and the ketosis process so in that period, you go through a downfall phase which is known as keto flu and it has certain symptoms like fatigue, nausea, headache, and brain fog is one of them. Your brain also getting adapted to the new energy source that is fat but once it does, all the symptoms and sickness will go away including brain fog.

When the ketones start to fuel your brain, brain fog diminishes.

How to Fix your Short-term Memory Loss?

Short-term memory loss means that you forget things you heard or see in a very short period, usually people face memory loss in old ages. As some people think that keto can cause short term memory loss so there are certain ways through which you can fix short-term memory loss:


Exercise is a very good thing that can help you with short-term memory loss, it keeps the brain more active and energetic and you can do exercise while following a keto diet plan so do regular consistent exercise and when you do not want to do exercise, you can also take long walks.

Intermittent fasting:

Intermittent fasting has been very successful in fixing short-term memory loss as it increases neurogenesis which is the formation of nerve cells that ultimately results in improved and sharp memory.

The combination of intermittent fasting and keto diet is already very well appreciated so, it will not be a problem for you to do them together.

Hyperbaric oxygen therapy:

This therapy is also a way to fix memory loss but not a lot of people do that because it is proper medical treatment and you should only do it when the problem gets very serious.

Vitamin D:

Vitamin D is a very important nutrient for the body especially for the working of the hippocampus, the part of the brain which deals with memory storage. So, try to include more vitamin D food sources in your diet plan and also sit in the sun for a little while every day.

Vitamin B1:

Vitamin B1 is considered one of the most crucial vitamins for body functioning and it also helps with short-term memory loss. Add more vitamin B1 food sources to your diet plan like nutritional yeast, beef liver, nuts, eggs, leafy green vegetables, etc.


Consuming zinc also helps with short-term memory loss so add zinc to your diet through various food sources such as seafood, poultry items, nuts, and seeds, etc.


Many studies have suggested that having a diet plan or ketone intake can help you with short-term memory loss. The best way to add ketones to your diet is by doing the keto diet, as it is the healthiest and natural way to produce ketones in the body which will fuel the brain and help in improved brain functions.

Can Fasting or Keto Diet Reverse a Poor Memory from Aging?

Many adults or aged people are very curious about this thing that intermittent fasting or keto diet can help them reverse a poor memory so the simplest answer would be yes because intermittent fasting allows the body to undergo autophagy which lets the damaged nutrient recycled which can be helpful for better memory. More overly, doing a keto diet or intermittent fasting stimulates the production of such hormones or substances that cause nerve cell growth which ultimately helps with poor memory.


So, if you do an intermittent fasting or keto diet and you can also do them together, you can reverse poor memory from aging, and also adding MCT oil to the diet plan will give even better results.


The Keto diet has a very good and healthy impact on the human body and regarding memory loss conditions, so it is proven by many scientific studies and researches that the keto diet is good for memory loss or any other brain abnormality like brain fog, epilepsy, brain cancer, etc. And if you feel like difficulty in remembering or focusing on something while at the start of the diet plan so, there is no need to worry about it, it is just the brain is getting adapted to the new source of energy which is ketones.

But all you have to do is to follow the diet plan strictly and with discipline so that you can get all the benefits of it.
