Brain, Food and Weight

October 21st, 2008 by Christiane

Overweight people just enjoy food more than people of normal weight and that’s the reason why they eat more and gain weight!

You think so? Think again!

Scientists at the Oregon Research Institute compared the brain responses of skinny and overweight people while drinking a milkshake. It turned out that a brain region called dorsal striatum, which the scientists describe as “a dopamine-rich pleasure center” became active. However, that brain region was less active in overweight people than in lean people.

Previous brain scans have already shown that overweight people have fewer dopamine receptors that normal weight people. This difference seems to be caused by genetics.

One of the senior scientists at the Oregon Research Institute concludes, based on the study results, that opposed to common belief obese people get in fact LESS satisfaction from food and to compensate for that they eat more.

Optimism key to White House?

October 3rd, 2008 by Christiane

Researchers at the Positive Psychology Center at Penn University have determined that in the past 100 years, the most optimistic candidates have won more than 80 percent of presidential elections. The reason why voters prefer optimistic candidates could be that they inspire hope.

With regard to the current candidates, the psychologists find Barack Obama and John McCain to be equally optimistic and Sarah Palin slightly more optimistic than Joseph Biden.
