Researchers from Great Britain and Poland found out that the consumption of food with a high content of fat is the cause of activation in the brain rats of a group of neurons controlling a sense of saturation, which leads to overeating and developing obesity. The article of scientists is published in The Journal of Physiology.
Scientists from Bristol and Jagiellonian universities conducted an experiment in two groups of rats – on a balanced (where 10 percent of calories accounted for fat) and on rich fats (more than 70 percent of calories) diet. Powered by mice around the clock tracked for four weeks.
The electrophysiological observations carried out by researchers the activity of the neurons of mice allowed researchers to identify changes in their circadian rhythms and the response to the associated hormones. It turned out that the mice with rich fats diet changed both the daily rhythm of neurons of the dorsal complex of the wandering nerve, regulating saturation and their reaction to hormones associated with the feeling of appetite. Peak activity of neurons occurred on the evening. By the end of the study, the rat was greatly gained weight.
In addition, it turned out that obesity stuck daily rhythms of food intake and emission of hormones associated with food intake.
