Keto Diet and Cognitive Function

By Suzanne Anderson April 5, 2023 31 mins read 173 Views

Ketogenic diets are known for their effects on energy and weight loss -- but they also show some potential to improve cognitive function. Research suggests that ketones may boost mental clarity and reduce brain inflammation, improving memory in adults with Alzheimer's disease (AD) and older adults at risk for the condition.

How Does the Keto Diet Affect Cognitive Function?

The keto diet forces the brain to switch from using glucose as its primary fuel source to relying on fats. This is called ketosis and can help improve cognitive function in people with epilepsy or mental health conditions like dementia.

The Keto diet may also improve cognition in healthy individuals. In one study, participants who were given a high-fat diet that was low in carbs (the keto diet) improved their memory and attention.

Another study found that a diet containing MCT (a type of fat that converts to ketones) and protein improved cognition in adults who were at risk for Alzheimer’s disease. Compared to a control group, those on the diet had a significant improvement in their ability to perform tasks that require the use of both working memory and bi-conditional association.

However, the current study found that MCT boosted ketone bodies in ApoE4-negative individuals who were on a ketogenic diet and did not improve the memory of those with amnestic mild cognitive impairment (MCI). The discrepancy between groups based on global cognitive function suggests that ketogenic interventions are not a one-size-fits-all approach and should be tailored to individual needs.

Can the Keto Diet Improve My Ability to Think and Process Information?

The keto diet reduces carbohydrates to help your body burn fat instead of glucose for fuel. This changes the way your brain uses energy, giving you more mental clarity.

Ketones are a natural fuel source for your brain that the liver produces from the fat you eat or store in your body. They’re known as ketone bodies and can cross the blood-brain barrier, providing your brain with an alternative source of fuel when glucose runs out.

They also trigger the production of BDNF, which is a protein that supports and encourages the growth of new neurons and neural pathways in the brain. BDNF is particularly important for learning, memory, and higher thinking.

Ketones are also neuroprotective, preventing oxidative stress and damage to the brain. This may help prevent conditions like anxiety, depression and Alzheimer’s disease.

What Can I Eat on a Keto Diet?

The keto diet is a low-carb, high-fat eating plan that helps you achieve a state of ketosis. You’ll eat mostly protein, healthy fats, and small amounts of carbohydrates.

The main food groups to eat on a keto diet are meat and poultry, nuts and seeds, and high-fat dairy products. Meat options like chicken, beef, and turkey are a great source of high-quality protein.

Nuts, seeds, and avocados are also good sources of fat on the keto diet. These foods are high in fiber and can help keep you fuller longer.

Cheese is another great choice, as it’s very low in carbs and contains a high amount of saturated fat. It’s also high in calcium, which may reduce appetite and promote weight loss.

Coffee and tea are also popular options on a keto diet, as they’re low in carbs. They’re also a good source of antioxidants and are linked to a host of health benefits, including a lower risk of dementia.

What Can I Avoid on a Keto Diet?

When you follow a keto diet, your body goes into a metabolic state called ketosis. This state is when your body burns fat instead of carbohydrates for energy.

The key to the keto diet is to keep your carb intake low and choose foods that are nutrient-dense. Avoid processed foods and fast food, which typically contain high amounts of sugars and trans fats.

Meats, fish, eggs, and non-starchy vegetables are perfect choices on a keto diet. These low-carb, nutrient-dense foods help you achieve and maintain a healthy weight while reducing exposure to toxins like pesticides and herbicides.

Meat, fish, poultry, and deli meats can be a great source of protein on the keto diet. They also contain minimal carbohydrates and are rich in vitamins, minerals, and antioxidants.

Frequently Asked Questions

What happens during the first week with keto?

It is essential to research your options before starting a ketogenic eating plan. Knowing what foods are best and how many carbs you can consume daily will help you make informed choices. It's also important to learn which foods provide the best balance of macronutrients.

Now it is time to build meals that fit your new lifestyle. Your body will adapt faster if you avoid processed sugars and eat whole, unprocessed foods. The simple addition of more healthy fats and protein to each meal can help you curb your cravings while improving energy levels.

The next step in the keto diet is to learn proper portion control. You can track macros and consult with a nutritionist for one-on-one guidance.

When transitioning into keto, newcomers must take their time. They need to ensure that their bodies are ready for the change before they can go full throttle. You should get plenty of rest and keep hydrated during this transition. Allow yourself three days to assess whether this is working for your body. Each person responds differently to different things so you can give it some time.

Can you eat fruits on keto?

Do you want to know if fruit can be eaten on a low-carb diet? The answer is yes, but with caution.

To stay in ketosis and burn fat, the idea is to keep carbs to a minimum. You can still eat certain fruits if you follow a balanced, healthy keto diet.

Low-carb fruits and vegetables can be incorporated into a keto meal program, but should be consumed in moderation. Different fruits have different amounts of carbs. For example, bananas have significantly higher carbs than avocados.

Your body uses sugar in fruits to produce energy. An overload of sugar can cause blood sugar spikes and derail your progress when trying to achieve nutritional ketosis. Be mindful of how much sugar you are consuming and don't overindulge in it.

Fresh fruit is better than processed or sugary snacks. It provides essential vitamins, minerals and fibre that help fuel the body without adding extra carbs like desserts or candy bars.

You should consider whether or no fruit is better than sugary treats when deciding whether the keto diet is right. However, you must remember that fresh fruits are more nutritious than sugary treats.

Can you eat oatmeal on keto?

Unanswered questions can be the hardest to find solutions for. And when it comes to finding the right food choices for the keto diet, many still feel overwhelmed and lost. Especially with items like oatmeal, which is full of carbs.

But despite popular belief, oatmeal can be successfully integrated into a keto lifestyle - under the right circumstances. It all depends what type you buy, and how many you consume.

Finding a form of "keto-approved" oatmeal starts with examining ingredients like nuts, seeds, and other low-carb additives that bundle together in one deliciously nutritious meal. Moreover, pure oats are naturally rich in fibre, protein, vitamins, and minerals - making them highly content by nature without sacrificing the keto rulebook.

When adding oats into your daily diet, you'll need to be careful about how much you eat. You don't need to run a marathon, or eat too many overnight meals. Instead, you can exercise self-control and limit your portions while maximising flavour with innovative ingredients like coconut milk, cinnamon powder, and chia seeds.

If done properly, oatmeal can make a great breakfast choice within a Keto nutrition plan. You don't have to compromise your principles for taste. Proper prep can bring you serious results.

Is keto right for you?

You must make the conscious choice to ask tough questions, do your research, and find out what "right" is for you. That is why the age-old keto diet has been around for so long and remains popular today - it is believed to offer health benefits far beyond just weight loss.

Ask yourself, what are my health goals? Do I want to lose weight, improve mental clarity or balance my gut microbiome? If done with care, keto can be a great place for a start.

Keto works to reduce the amount of carbohydrates we consume, and is best when there are 20 grams a day. This forces our bodies into a biochemical process known as nutritional Ketosis. Our bodies use fat as an energy source, instead of sugar and glucose. Although it may seem difficult at first to stick to this carb limit, you will soon learn how to do it.

If you can maintain a high nutritional quality and consume certain healthy fats (such as Omega 3 and other beneficial mono/polyunsaturated fatty acids found in avocados or salmon), you should experience beneficial metabolic effects when you follow a ketogenic lifestyle. This is true regardless of whether you're looking to improve your overall health or body composition.

Keto can be sustainable if balanced with optimal nutrient intake, so make sure any food choices adhere to real whole foods in their most natural form for maximum benefit - don't overestimate portion sizes either! If done correctly, keto could be very beneficial for your individual needs, so take the time to learn more about it through reliable sources before taking any big steps forwards (or backward).
