In the process of thinking brain burns up calories in half a minute, but to lose weight that does not help

Our gray matter is known to consume great amounts of energy. This means that its "filling" requires adequate nutrition. A reasonable question arises: why lessons from brainwork nobody loses weight?

In any documentary devoted to the evolution of man, it necessarily comes to an enlarged brain size. Typically, the confirmation demonstrate ranked skull - from the small and ancient, to the largest, most closely related to our period.

And always emphasized - the larger the brain, the more energy it consumes. That is, the greater became the brain, the more food we can produce, improving with the help of tools; the better we ate - the greater the brain, and so on. This cycle, scientists say, continues today.

So why, then, programmers and mathematicians do not become happy owners of slender bodies, just sitting in front of their computer screens and solving challenging puzzles?

To make it to compare: for the survival of the common man requires about 1,300 calories a day. One minute walk body burns 4 calories. A kickboxing classes consuming 10 calories per minute.

The brain if nothing special busy burns about 1.10 calories per minute. In fact, it's not so little as it seems, if we take into account that the brain - the inertial mass, is only two percent of the human body.

But when we "turn on the brain at full capacity": reshaemkakuyu-nibudhitroumnuyu task or thinking about the problem, the number of calories burned could rise to 1, 5 min. This is really a lot.

Even more impressive is the fact that a group of researchers has found a way to measure the intensity with which a man thinks at some point in time. To do this with the help of special equipment, they calculated how much glucose is taken up various parts of the brain.

It turned out that in the process of active thinking involved, mainly the frontal lobes of the brain. The problem is that we do not employ the proportion of the time. Therefore, although the brain, on average, burns about 300 calories per day, it always possible to burn more.

The only question is how often we strain our gray matter.
