People cannot be both healthy and intelligent

If you need too much brain activity, the brain will possess most of the energy you load even if it makes other body parts become thinner.

Maybe you've met a scientist somewhere all day buried in the lab, or someone spent the day squeezing brains on a desk. They are physically inactive, often looking sicker than the size of people who should have consumed.

A study published in Scientific Reports explains that: your brain is the most energy-consuming thing on the body. Not only that, it is also a selfish person, willing to concentrate all the energy and energy you have towards you when you need it. So, don't try to solve a thorny problem while doing something that requires energy, you will quickly slip and encounter a picture because your body is weak and visible.

The research team at the University of Cambridge found that the human brain makes up about one-fifth of the body's energy source. It is also the "overall commander" in supplying energy to body parts.

In extreme situations, for example when you have a diet that is too small or when both physical and mental are required to work, the brain will not be afraid to take energy to prioritize its fulfillment. before, even if other parts are deprived and weakened. The main type of energy that the brain needs comes from glucose metabolism.

In one experiment, the team recruited 62 excellent school boys, with an average age of 21. Boys were judged on three situations: just rowing, trying to do one Memory test by remembering some words and finally doing both things at the same time.

When checked memory while sailing, 62 smart guys were completely embarrassed. When they remembered 9.7% of the words in the quiz, their muscle strength decreased by 12.5%. They absolutely did not actively prioritize memory but the brain itself favored itself. And surprisingly, taking responsibility for memory is more costly than sailing.

The lead author of the study, Daniel Longman, a biological-anthropologist at the University of Cambridge, said this explains why in people who suffer from chronic lack of food, the brain is the most refined part. on their bodies. Similar to children born in need, the brain is willing to limit the growth of other body parts to secure itself.
