We all know that what we eat can affect our physical health, but did you know that it can also impact our mental clarity and overall mood? One culprit for brain fuzziness is carbohydrates. How can carbs cause brain fog?
Recent research has shown that a diet high in carbohydrates can actually lead to brain fog.
Here’s a closer look at how carbs affect blood sugar levels and brain function, how can carbs cause brain fog and some tips for managing carb intake to minimize the risk of developing this frustrating condition.

Brain Fog and Carbohydrates
Carbohydrates have a greater effect on the brain and nervous system than most people think.
Blood sugar levels and insulin responses are well known in reference to obesity and inflammatory processes, but when it comes to neurological integrity there can be a gap in understanding and appreciation.
Blood sugar levels have a significant impact on brain chemistry; the foods we eat can help sustain steady levels of blood sugar or certain foods can induce sugar crashes or spikes that can cause feelings of fogginess, anxiousness, depression, lack of focus, or apathy.
Most people understand that overeating or eating the “wrong” foods can contribute to weight gain, changes in body composition (increased fat percentage relative to lean muscle), and cardiovascular conditions.
Recently, with new research, certain diet and nutritional choices have been linked to depression and other neurodegenerative diseases.
The key to the nutritional impact on the nervous system is centered on inflammation, and how certain foods can have a pro-inflammatory effect on the brain while others have an anti-inflammatory effect.
Sustained, long-term inflammation can lead to short-term symptoms (such as brain fog) but also long-term changes (such as Alzheimer’s or dementia).
There are different types of carbohydrates, and they can be broadly classified as simple or complex.
Simple carbohydrates are typically processed and refined, and they are digested and absorbed quickly. Examples of simple carbohydrates include table sugar, candy, syrups, pastries, and other sweets.
In contrast, complex carbohydrates are typically unprocessed and unrefined, and they are digested and absorbed more slowly. Examples of complex carbohydrates include starchy vegetables (such as potatoes and corn), legumes (such as beans and lentils), and whole grains (such as oats and barley).
How can carbs cause brain fog?
The body breaks down all carbohydrates (simple and complex) into sugar (glucose) which is then used for energy.
When we eat simple carbohydrates, the sugar is absorbed quickly into the bloodstream and the resulting spike in blood sugar levels can lead to the release of insulin.
Insulin is a hormone that helps to regulate blood sugar levels. When blood sugar levels are high, insulin is released to help move the sugar into the cells where it can be used for energy.
The problem with simple carbohydrates is that the sugar is absorbed too quickly and the resulting spike in blood sugar levels can be followed by a crash. This can lead to feelings of fatigue, irritability, and brain fog.
In contrast, complex carbohydrates are absorbed more slowly and they do not lead to the same spikes and crashes in blood sugar levels.
The other problem with simple carbohydrates is that they can have a pro-inflammatory effect on the brain. Inflammation is a normal process that helps the body to heal and repair itself.
However, when the body is constantly in a state of inflammation, it can lead to a variety of problems. Chronic inflammation has been linked to a number of diseases, including Alzheimer’s disease, dementia, depression, and other neurological disorders.
Simple carbohydrates can promote inflammation by increasing the levels of pro-inflammatory cytokines in the body. Cytokines are proteins that are secreted by cells and they have a variety of effects on the body, including the promotion of inflammation.
There are a few different ways to reduce the pro-inflammatory effect of carbohydrates.
One way is to choose complex carbohydrates instead of simple carbohydrates. Complex carbohydrates are absorbed more slowly and they do not lead to the same spikes and crashes in blood sugar levels.
Another way to reduce the pro-inflammatory effect of simple carbohydrates is to choose carbohydrates that are high in fiber.
Fiber is a type of carbohydrate that is not broken down and absorbed by the body. Instead, it passes through the digestive system relatively intact.
Fiber can help to slow down the absorption of sugar and it can also help to reduce the pro-inflammatory effect of simple carbohydrates.
Simple carbohydrates can have a negative effect on the brain and nervous system. They can lead to spikes and crashes in blood sugar levels, which can cause feelings of fatigue, irritability, and brain fog.
Simple carbohydrates can also promote inflammation, which has been linked to a number of neurological disorders. To reduce the negative effect of simple carbohydrates, choose complex carbohydrates instead, and choose carbohydrates that are high in fiber.
Can Carbs Cause Brain Fog?
Carbohydrates are one of the main nutrients that affect blood sugar levels. When carbs are broken down by the body, they turn into glucose, which is then used for energy.
If there are more carbs than what the body needs for energy, the excess glucose is stored as glycogen or fat.
When you eat foods high in carbohydrates, your body breaks them down into sugars and releases them into your bloodstream. This causes a rise in blood sugar levels, which your pancreas responds to by releasing insulin.
Insulin helps move sugar from your bloodstream into your cells so it can be used for energy or stored for later use.
If you regularly consume more carbohydrates than necessary, over time this could lead to insulin resistance – meaning that even though there’s plenty of insulin available, it becomes less effective at doing its job.
This results in higher blood sugar levels since the sugars aren’t being effectively moved out of the bloodstream and into cells. Eventually, this could progress to type 2 diabetes.
People with diabetes have an increased risk of developing serious health complications including heart disease, stroke, kidney disease, nerve damage, and vision problems.

Can a Low-Carb Diet Help Improve or Prevent Brain Fog?
A low-carb diet can help improve or prevent brain fog by stabilizing blood sugar levels and improving insulin sensitivity. Brain fog is often caused by spikes in blood sugar, so a diet that helps to keep blood sugar levels stable can be beneficial.
There are a variety of ways to structure a low-carb diet, so it’s important to work with a Registered Dietitian Nutritionist (RDN) to find the approach that works best for you.
Here are a few tips on how to manage your carb intake and minimize the risk of brain fog.
1. Eat Complex Carbs Rather Than Simple Sugars
When it comes to preventing brain fog, one of the most important things you can do is regulate your blood sugar levels.
Eating complex carbohydrates instead of simple sugars is a great way to keep your blood sugar stable and prevent spikes that can lead to feelings of fatigue or mental confusion.
Complex carbs are found in foods like whole grains, legumes, and vegetables, so aim to include these in your diet as much as possible.
2. Avoid Processed Foods and Refined Carbohydrates
Processed foods and refined carbs are another big no-no when it comes to mental health. These types of foods are typically high in sugar and low in nutrients, which can wreak havoc on your blood sugar levels and leave you feeling tired and run down.
Stick with whole, unprocessed foods whenever possible for best results.
3. Get Adequate Fiber From Fruits, Vegetables, and Whole Grains
Getting enough fiber is another key part of managing carb intake effectively. Fiber helps regulate digestion and metabolism, both of which play a role in keeping blood sugar levels balanced.
Make sure to get plenty of fiber-rich fruits, vegetables, and whole grains into your diet every day to help keep brain fog at bay.

Conclusion
Can carbs cause brain fog? If you’re struggling with brain fog, it might be worth considering your carb intake. Carbs can cause blood sugar levels to spike and crash, which can lead to fatigue and mental clarity issues.
There are certain types of carbs that are more likely to cause these problems, so it’s important to be aware of what you’re eating. A low-carb diet may help improve or prevent brain fog by stabilizing blood sugar levels.
If you want to try this approach, work with a registered dietitian or nutritionist to ensure you’re getting the nutrients you need.
