Understanding The Benefits of Keto for Brain Health
From memory lapses and brain fog to the exhausting cloud of chronic fatigue, these symptoms often stem from underlying metabolic problems in the brain.
So, let’s imagine your brain as a hybrid car that can run on both gasoline and electricity. In our bodies, glucose (the breakdown product of sugar and carbs) is like gasoline, and ketones (the breakdown product of fats) are like electricity. For many suffering from cognitive decline or chronic fatigue, their brains struggle to switch from using glucose to ketones, leading to what we call metabolic inflexibility. This condition can manifest as hypoglycemia (or periods of low blood sugar), headaches, fatigue, and anxiety, but also as memory lapses, difficulty concentrating, and mental fog, significantly impacting your daily life. When your brain can’t effectively switch its fuel sources, it doesn’t run as efficiently, which can leave you feeling mentally sluggish and just plain crumby.
By shifting to a more ketogenic diet, which emphasizes high-quality fats and minimizes carbohydrates, your brain can begin to regain its metabolic flexibility — that ability to efficiently switch between using carbohydrates and fats for fuel. This flexibility is crucial because ketones are actually a more stable and efficient energy source compared to glucose, providing consistent energy without the highs and lows associated with sugar spikes. This switch not only supports overall brain and energetic health but also encourages the repair and rejuvenation of brain cells, which is vital for maintaining cognitive function as we age.
A ketogenic diet, low in carbohydrates and blood sugar spikes, also drastically reduces inflammation within the body and brain, which, if left unchecked, can lead to cognitive decline and other neurological issues over time. These anti-inflammatory effects can also slow the progression of cognitive decline and even improve brain function, offering a wonderful beacon of hope for those battling chronic brain conditions.
So, when your brain begins using ketones for energy, many report a significant lift in the fog — an enhancement in their mental clarity and focus. This effect is partly due to ketones being a more efficient fuel but also results from their ability to reduce inflammation and oxidative stress (stress at the cellular level) and enhance mitochondrial function (the parts of your cells that make energy). Essentially, when your brain cells operate more efficiently, you experience clearer thinking, better concentration, and an overall sense of mental acuity.
Likewise, this consistent level of energy can help alleviate the daily fatigue that many people suffering from chronic fatigue feel, helping to improve both physical and cognitive endurance throughout the day.
Proper Implementation of a Ketogenic Diet
Now, transitioning to a ketogenic diet means more than just cutting carbs and adding fats. It’s about choosing the right types of each to support not only brain health but overall metabolic balance.
The Basics of Keto
At its core, the ketogenic diet is high in fats, moderate in proteins, and very low in carbohydrates. The goal is to shift your body’s metabolism from relying primarily on glucose for energy to deriving it from fat, leading to the production of ketones. When your body runs on ketones, it can positively affect your brain health by providing a consistent, efficient energy source that also reduces oxidative stress and inflammation.
However, not all keto diets are created equal. A ‘clean’ keto diet focuses on nutrient-dense foods to maintain overall health while still adhering to the keto principles. This means prioritizing:
- Healthy Fats: Such as avocados, olive and coconut oil, nuts, and seeds, which provide essential fatty acids that support brain health.
- Butter from grass-fed cows can also be a good source of healthy fat, if you are tolerant to dairy.
- Adequate Proteins: From sources like grass-fed meat, fish, and eggs, which are crucial for muscle maintenance and building the various enzyme and chemical pieces needed for your brain to function smoothly.
- Low-Carbohydrate Vegetables: Like leafy greens, broccoli, and cauliflower, which are high in fiber and packed with vitamins and minerals without spiking your carb intake.
What To Eat on a Ketogenic Diet
On a clean ketogenic diet, it’s crucial to choose foods that not only adhere to the macronutrient requirements but also support brain health through essential micronutrients. These can include foods such as:
- Fatty Fish: Such as salmon, mackerel, and sardines, which are excellent sources of Omega-3 fatty acids, crucial for reducing inflammation and supporting cognitive function.
- Nuts and Seeds: Almonds, walnuts, chia seeds, and flaxseeds that provide healthy fats, proteins, and fiber, all while keeping carb counts low.
- Healthy Oils: Olive oil, coconut oil, and MCT oil that are great for dressing salads and cooking, providing fats that enhance ketone production.
- Leafy Greens: Spinach, kale, Swiss chard, and various lettuces are low in carbs and high in fiber and antioxidants, supporting overall cellular health.
- Cruciferous Vegetables: Broccoli, cauliflower, bok choy, and Brussels sprouts offer fiber and essential nutrients with minimal impact on carb limits.
- Avocados: A keto staple, rich in monounsaturated fats, potassium, and fiber, helping to maintain both heart and brain health.
- Eggs: High in protein and fats, eggs are versatile and beneficial for brain function due to their choline content.
- Berries: Blueberries, raspberries, and blackberries can be enjoyed in moderation; they’re rich in antioxidants that protect the brain from oxidative stress.
- Full-fat Dairy: From pasture-raised cows, in moderation, items like cheese, Greek yogurt, and heavy cream can provide additional fats and proteins without too many carbs, enhancing the ketogenic effect as well.

A Day of Eating Keto
Now, let’s take a look at what a day of eating this way might look like!
- Breakfast: A scramble of eggs and spinach cooked in coconut oil, served with avocado slices and a few cherry tomatoes.
- Lunch: A large bowl of mixed greens topped with grilled chicken, pecans, avocado, feta cheese, and a vinaigrette made from olive oil and apple cider vinegar.
- Dinner: Baked salmon with a side of asparagus sautéed in garlic and olive oil, with a serving of berries for dessert.

Pitfalls
Now, when adopting a ketogenic diet, it’s easy to fall into traps that can negate the health benefits, particularly for brain health:
- Over-reliance on Processed Foods: While bacon and sausages and all the packages labeled “keto” are, in fact, keto-friendly, they often contain preservatives and fillers that are not ideal for your brain health. Opt for whole foods and grass-fed, organic, and minimally processed options whenever possible.
- Ignoring Vegetable Intake: It’s essential to include a variety of vegetables to ensure adequate fiber and micronutrient intake, which support digestive and cognitive health.
- Too Much Dairy: While convenient, excessive dairy can lead to inflammation for many people, potentially worsening brain fog and other cognitive issues.
- Not Enough Variety: Eating a limited range of foods not only makes the diet harder to maintain but also risks nutrient deficiencies that can impact brain function. Variety ensures a broader range of nutrients and keeps the diet enjoyable.
- Neglecting Hydration and Electrolytes: As carb intake lowers, so does water retention, which can lead to dehydration. Additionally, important electrolytes such as sodium, potassium, and magnesium, that are crucial for cognitive function and overall health, are used quicker. So, to stay hydrated and keep your electrolytes up, you can add a pinch of celtic sea salt to your water or drink a clean electrolyte solution, such as LMNT. This is important in not only furthering your cognitive health, but also avoiding symptoms associated with the “keto flu,” a time when people sometimes experience more fatigue, irritability, and brain fog for the first few days as their body transitions to mild ketosis. If you choose to drink an electrolyte solution, LMNT is the only brand I recommend at this time due to its clean ingredients.
By being mindful of these pitfalls and focusing on nutrient-dense foods, you can optimize the ketogenic diet to enhance your cognitive function and overall brain health.
Additional Best Practices for Clean Keto
Now, it’s crucial to approach this dietary shift with careful consideration and the guidance of professionals. Here’s what you need to know to make keto work for you over the long term.
- Before making any significant changes to your diet, especially one as specific as the ketogenic diet, it’s important to consult with your healthcare provider. This is especially true if you have pre-existing conditions such as diabetes, heart disease, or high blood pressure. A healthcare professional can help tailor the keto diet to your individual health needs and monitor any potential impacts, especially on medications, ensuring that your transition to ketosis is safe and beneficial.
- Then, once on the keto diet, it’s essential to regularly monitor your health markers. This includes checking blood sugar levels, lipid profiles (usually with your healthcare provider), blood pressure, and ideally ketone levels. If interested in tracking blood sugar and ketones, this is the dual glucose and ketone monitor I recommend. Additionally, observing any cognitive changes is crucial. Many find improvements in clarity and energy, but it’s important to note any negative changes and discuss them with your healthcare provider.
- Maintaining a ketogenic diet long-term also requires strategic planning and integration into your lifestyle. Some strategies may include:
- Meal Planning: Preparing keto-friendly meals in advance to help avoid the temptation of off-diet choices. This also includes looking at restaurant menus ahead of time so you’re prepared to order choices that fuel your body properly.
- Educational Resources: Continuously educating yourself about ketogenic living to provide new ideas and motivation. Signing up for my newsletter is a great way to get started here. You can do so by using the link in the description below.
- Support Networks: Joining keto diet groups or online communities or going through a program like mine can offer support, troubleshooting, and recipe ideas.
- It’s also important to understand that not everyone needs to remain in ketosis indefinitely. Many people, especially those focused on brain health, use the keto diet to achieve metabolic flexibility—once this is re-established, they can reintroduce more carbohydrates into their diet. This approach involves eating lower carbohydrates than the standard American diet (yes, that abbreviation spells “sad”) but includes periodic returns to mild ketosis. This cycling can help make the diet more sustainable and less restrictive while still reaping the benefits of enhanced metabolic flexibility and superior brain function.
Transitioning to a ketogenic diet can be a powerful step towards revitalizing your brain health and energy levels. By understanding and implementing the principles of keto, you’re not just altering your diet; you’re fundamentally transforming how your brain operates. We’ve explored how this diet reduces inflammation, enhances metabolic flexibility, and provides a steady, efficient energy source that can alleviate symptoms of cognitive decline and chronic fatigue.
