A study published in the journal “Brain Research” has revealed that obesity has negative effects on brain size, altering the functioning of those areas that govern eating behavior.
According to researchers at New York University School of Medicine, in addition to being correlated with increased risk of type 2 diabetes, a disease that compromises the cognitive functions, obesity also causes a disorder that makes the affected persons eat more and more.
In order to check the impact of the extra weight on brain structure, Antony Convit’s team examined 63 people. In particular, the researchers scanned the brains of 44 obese people with functional magnetic resonance, and then they compared the results obtained from 19 “thin” people of the same age and with the same level of training.
It was revealed that obese individuals have more water in the amygdala and a smaller orbitofrontal cortex and that the neurons in these areas are in smaller numbers than normal.
