Tag: Glucose vs ketones

The human brain, despite making up only 2% of the body's weight, consumes about 20-25% of its resting energy. Under normal circumstances, this energy comes almost exclusively from glucose. This fact leads many to wonder: does the brain prefer glucose or ketones, and how does it adapt to different fuel sources?

According to research, the human brain, which accounts for only 2% of body weight, consumes over 20% of the body's total energy at rest. This remarkable energy demand raises questions about optimal fuel sources, with a growing focus on whether your brain works better on ketones than on its usual fuel, glucose.

Studies have shown that switching to a ketogenic diet can lead to more stable and long-lasting energy levels, and many users report feeling more focused and alert. This happens because the body undergoes a fundamental metabolic shift, transitioning from burning glucose to relying on fat-derived ketones for fuel. The question of why does keto give you more energy is rooted in this change, offering insights into metabolic efficiency and brain health.

The human brain, though primarily a consumer of glucose, can derive up to 70% of its energy needs from ketones during periods of low carbohydrate availability. The critical question for many pursuing a specific nutrition diet is: does your body run better on ketones for overall performance and health, or does it thrive on its usual glucose-based system?
