Over a century ago, the ketogenic diet was first used to manage conditions like epilepsy, demonstrating the body's remarkable ability to adapt its fuel source. The key to how keto gives you energy lies in this metabolic adaptation, shifting your body from a glucose-dependent state to one that burns fat for fuel.

According to a study published in *Psychosomatic Medicine*, students who engaged in intense mental tasks consumed an average of 200 to 250 more calories than those who simply rested. So, what are the munchies while studying, and why does intense intellectual work drive us to snack? The answer lies in the brain's complex energy demands and how it signals for fuel, even when it's not truly needed.

During periods of low carbohydrate availability, such as fasting or intense exercise, the human body can undergo a remarkable metabolic shift to conserve its most precious energy source. This process, known as glucose sparing, is a crucial survival mechanism that prioritizes alternative fuels like fat and ketones to ensure a consistent glucose supply for vital organs.

The human brain is the body's most energy-demanding organ, consuming about half of all the sugar energy in the body to function properly. While often vilified, sugar, particularly glucose derived from healthy carbohydrates, is a vital fuel source with several key positive impacts on the body when consumed in moderation.

The brain, despite making up only 2% of the body's weight, consumes a disproportionate 20% of the body's energy at rest. Given this immense energy demand, the question arises: do our brains need glucose to function, or can they adapt to other fuel sources?

MCTs are processed differently by the body than other fats, converting into a rapid and clean source of energy. A high quality MCT oil is a highly purified and concentrated supplement of these beneficial medium-chain triglycerides, offering superior metabolic and cognitive benefits over lesser-quality alternatives.

Approximately 20% of the body's total energy expenditure at rest is consumed by the brain, despite it only making up about 2% of total body weight. While glucose is the brain's primary fuel, ketone bodies are the substance used by the brain as an alternative fuel source when carbohydrates are scarce. The ability to utilize ketones is a vital metabolic adaptation that allows humans to survive prolonged periods of starvation or low-carbohydrate intake.

The human brain, though only about 2% of the body's weight, consumes approximately 20% of its total energy, relying almost exclusively on glucose for fuel. Many turn to supplements like Glucose D for a quick energy boost, but the question remains: is glucose D good for the brain for sustained cognitive function?

The human brain, despite making up only about 2% of total body weight, consumes roughly 20% of the body's total energy expenditure at rest. For normal function, the brain's main fuel is glucose, a constant and reliable energy source delivered via the bloodstream. However, in extreme starvation, the body initiates a profound metabolic shift, forcing the brain to eventually utilize an alternative energy source.

The brain, comprising only 2% of the body's mass, consumes over 20% of its energy at rest. This makes the question, does your brain run better on ketones, a crucial one for understanding peak mental performance.
