Tag: Glucose and brain function

Following an overnight fast, studies consistently show that consuming a nutritious breakfast replenishes your brain's glucose supply, a crucial energy source for enhancing alertness and mental performance. This initial meal helps to overcome the sluggishness and foggy feeling that often accompanies waking up without fuel. The evidence suggesting that breakfast helps with concentration is strong across various studies and age groups.

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.
