Brain fat people were arranged differently than in lean

People suffering from obesity, the brain doesn’t work quite as those whose weight is close to the standard normal. This is manifested, first and foremost, that fat people, unlike the majority of lean, with age does not begin to love less sweet. To such conclusion the group of scientists from the University of Washington.

As experts explain, a person with age less hungry sweets. However, people who are overweight this occurs less often because, as a new study shows, they have somewhat different work remuneration system, which allows the person to feel positive emotions as a reaction to a particular situation.

The study’s lead author Yanina pepino, explains that the lowering of interest tooth in adults is often associated with a decrease in the number of dopamine receptors in the brain called the striatum. In order to test whether this observed dependence for people with different body mass index, the researchers conducted an experiment involving 44 volunteers, of whom 20 had a “normal” BMI, and 24 were suffering from overweight or obesity. The ages of the participants ranged from 20 to 40 years.

All participants were asked to drink several drinks with different sugar content and tell which one they find most delicious. Thus, researchers monitored how the brains of participants by positron emission tomography followed the work of the brain of volunteers. In the result, the researchers found that thin people age, the number of dopamine receptors and the degree of love to the sweet drinks were linked. At the same time, those participants whose weight was above the average, such dependence could be traced to a much lesser extent.

Scientists admit that their findings may indicate the existence of any under-explored aspects of the relationship between metabolism and brain function. The experts published their study in the journal Diabetes.
