The reason is that ketone bodies are a more efficient fuel than glucose. Indirect calorimetric analysis revealed a moderate increase in VO2 and a decrease in VCO2 and heat with ketosis. These results suggest that ketosis induces a moderate uncoupling state and lower oxidative efficiency compared to glucose oxidation.
Does the brain work better with ketones or glucose?
Brain on Ketones: Energetics, Oxidation and Inflammation
During metabolic stress, ketones serve as an alternate 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 of oxygen used.
Can the brain use ketones instead of glucose?
The brain depends on glucose as its primary energy substrate, but is able to utilize ketones such as β-hydroxybutyrate (βHB) and acetoacetate (AcAc), as occurs with fasting, prolonged starvation, or eating chronicle of a high-fat/low-carbohydrate diet (ketogenic diet).

Does the brain work better with ketones?
Animal studies have shown that ketone bodies can increase mitochondrial efficiency in the brain in addition to providing a new energy substrate.
Why are ketones healthy?
Unlike fatty acids, ketones can cross the blood-brain barrier and provide energy to the brain in the absence of glucose. Ketosis is a metabolic state in which ketones become an important source of energy for the body and the brain. This happens when carbohydrate intake and insulin levels are low.
Why does the brain prefer glucose?
Glucose metabolism provides the fuel for physiological brain function through the generation of ATP, the basis for neuronal and non-neuronal cellular maintenance, as well as the generation of neurotransmitters.
Does the body use ketones for energy?
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 times when glucose is not readily available. This is because, unlike other organs in the body, the brain has an absolute minimum need for glucose.
What should my glucose level be in ketosis?
During nutritional ketosis, it is normal to have blood ketone levels of 0.5 to 3.0 millimoles per liter (mmol/L). According to the American Diabetes Association, a person should check their ketone levels if their blood sugar is above 240 milligrams per deciliter (mg/dl).
Can the brain function without glucose?
Ultimately, your brain needs glucose to survive, but your liver is perfectly capable of producing the glucose you need – it doesn't have to come from your diet. A combination of glucose (derived from gluconeogenesis) and ketones may be the optimal fuel for long-term brain health.

Are ketones converted to glucose?
In the brain, ketone bodies are also used to convert acetyl-CoA into long-chain fatty acids. Ketone bodies are produced by the liver under the circumstances listed above, resulting from intense gluconeogenesis, which is the production of glucose from non-carbohydrate sources (excluding fatty acids).

What is keto brain fog?
Among these is the so-called keto flu, a collection of symptoms that appear between two and seven days after starting the diet. These include headaches, fatigue, nausea, and so-called “brain fog,” which refers to mental fatigue, fuzzy thoughts, and difficulty concentrating and remembering.
Does not eating carbs affect your brain?
“The brain needs glucose for energy and low carbohydrate diets can be detrimental to learning, memory and thinking. »
Do ketones help you lose weight?
Ketone supplements have been shown to decrease appetite, which can help you lose weight by eating less. In a study of 15 normal-weight people, people who drank a drink containing ketone esters were 50% less hungry after an overnight fast than those who drank a sugary drink (13).
