Female brain responds more actively to food! Why?

Female brain responds more actively to food. North American study explains greater obesity among women.

The women’s brain responds more actively when exposed to food than men, why women are more obese than men, showed a U.S. study published in the journal “Proceedings of the National Academy of Sciences.

The study, led by researchers Gene-Jack Wang, Brookhaven National Laboratory, and Nora Volkow, director of the National Institute of Drug Addiction and co-author of the discovery published by the National Academy of Sciences, says that women have the least capacity men to suppress hunger, which may explain the fact that there is more obesity among the female gender.

The researchers performed brain monitoring of the 13 women and ten men in fasting, when they found a different signal in the brain of women when exposed to their preferred food. Even using the technique of cognitive inhibition, used to suppress the thought of food and hunger, the brain responds to food of women remained active, while the man fell.

“The difference of gender is somewhat surprising and the nutritional needs may be responsible for this,” said Nora Volkow. He added: “The fact that the traditional role of women is to provide food for their children may be a stimulus in the brain of women to consume foods when available.”

Eric Stice, expert on eating disorders, described the discovery as provocative, saying that the difference may be related to the difference in estrogen and hormones between men and women. In 2006, 35.5 percent of North American women were obese, compared with 33.3 percent of men, according to data centers of control and prevention of diseases in the United States.

Challenging Establishement: Is it so Unnatural?

I figured out I had to make a post about this due to all the trends lately happening on the internet and sadly NOT (unsurprisingly) on the mass media .

If we say we know how the world and our society works, we don’t know how it works. Just like Feynman said about quantum mechanics.

In this new millennium I feel there are challenges made upon our established institution, possibly driven by our inquisitive and critical mind when focusing on the strange events taken place in the last 100 years or so.

Christian the Lion

When one of the most controversial issues of our society is the animal assumption of the Human being, I fond myself caught in this video! Everybody knows that Lions are dangerous, but what we didn’t know till now is that, a true wild animal like a lion can be a real friend.  I already knew that elephants had a tremendous recognizing capacity and had indeed a good memory to cry for their descending parents. However I never seen nothing like that, first of all its very difficult to integrate a domestic lion in a wild environment, second it’s very difficult rising to be a leader of the lion clan, and at last it’s unexpectable to be received like that by a Lion King and by its wild female. What do you think about that? 😉

Thanks Paulo and Ana for sharing this video with us!
