Deep dives
Understanding Brain Energy Limits
The brain operates within fixed energy limits that cannot be increased through conventional means such as diet or exercise. This inherent limitation means that attempts to improve mental capacity through willpower or caffeine are largely ineffective. Most of the brain's energy is consumed simply to maintain its physical structure, leaving little for cognitive functions. This explains why multitasking becomes challenging and why our attention span is compromised in a world filled with distractions.
