On a standard low carb diet, the brain will still largely depend on glucose, the sugar found in your blood, for fuel. However, the brain may burn more ketones than on a regular diet. On a ketogenic diet, the brain is mainly fueled by ketones. The liver produces ketones when carb intake is very low.
Do ketones make you smarter?
Ketones are a brain fuel that can readily pass the blood brain barrier and be used by brain cells. It’s no surprise that many people in ketosis feel a boost of mental clarity and focus.
Does the brain prefer ketones or glucose?
The brain is dependent on glucose as a primary energy substrate, but is capable of utilizing ketones such as β-hydroxybutyrate (βHB) and acetoacetate (AcAc), as occurs with fasting, prolonged starvation or chronic feeding of a high fat/low carbohydrate diet (ketogenic diet).
Does the brain function better on ketones?
Brain on ketones: Energetics, Oxidation and Inflammation
During metabolic stress, ketones serve as an alternative energy source to maintain normal brain cell metabolism. In fact, BHB (a major ketone) may be an even more efficient fuel than glucose, providing more energy per unit oxygen used.
Can the brain utilize ketone bodies?
Most organs and tissues can use ketone bodies as an alternative source of energy. The brain uses them as a major source of energy during periods where glucose is not readily available. This is because, unlike other organs in the body, the brain has an absolute minimum requirement of glucose.
What is keto brain fog?
Among these is what’s called the keto flu, a cluster of symptoms that emerge between two and seven days after starting the diet. These include headache, fatigue, nausea and so-called “brain fog,” which refers to mental fatigue, hazy thinking and difficulty with concentration and memory.
Can lack of carbs cause brain fog?
Taking away this glucose by going low-carb means the brain is left without its main source of ATP and energy. Short term “hypoglycemia” deprives the brain of glucose. In the initial days or weeks of keto, low glucose can cause brain fog.
Does not eating carbs affect your brain?
“The brain needs glucose for energy and diets low in carbohydrates can be detrimental to learning, memory, and thinking.”
Can keto cause stroke?
Worse, she adds, many people gain back the pounds after stopping keto. Research has found that weight, cholesterol and blood pressure fluctuations caused by yo-yo dieting can increase the risk of heart attack or stroke by 40 percent.
Can keto cause brain fog?
The so-called keto flu is a group of symptoms that may appear two to seven days after starting a ketogenic diet. Headache, foggy brain, fatigue, irritability, nausea, difficulty sleeping, and constipation are just some of the symptoms of this condition, which is not recognized by medicine.
Can the heart use ketones?
Ketone bodies can be utilized as fuel in the heart, brain and muscle, but not the liver. They yield 2 guanosine triphosphate (GTP) and 22 adenosine triphosphate (ATP) molecules per acetoacetate molecule when oxidized in the mitochondria.

Is keto bad for depression?
On the other hand, the keto diet may cause depressive symptoms or exacerbate depression in some people. Keto can be difficult to adjust to, and some common early symptoms of your body switching into ketosis — known as the “keto flu” — can be difficult to manage.
What triggers ketosis?
Triggers for ketosis
A low-carbohydrate diet can trigger ketosis. That is because a low-carb diet will cause you to have less glucose in your blood, which will, in turn, cause your body to burn fat for energy instead of relying on sugars.
How does ketones affect the body?
Ketones are chemicals that the body creates when it breaks down fat to use for energy. The body does this when it doesn’t have enough insulin to use glucose, the body’s normal source of energy. When ketones build up in the blood, they make it more acidic.
How do ketones leave the body?
Ketones upset the chemical balance of your blood and, if left untreated, can poison the body. Your body cannot tolerate large amounts of ketones and will try to get rid of them through the urine. Eventually they build up in the blood.
