Those who have ever followed a diet know how difficult it is to convince a person that they will consume less food than usual, especially during the first few days of the diet.
Often people break only after a day or two and eat something different from what is allowed in the regime. Then, of course, comes the great sense of guilt that they failed to cope, withstand hunger, and changed their diet.
It is not the lack of will that spoils the diet, according to recent research by American scientists, quoted by the Daily Express. The failure of the diet is most often due to the fact that people are programmed to look for food, explain the authors of the study from the Howard Hughes Medical Institute.
Brain cells, which are sensitive to hunger, make it absolutely impossible for some people to follow diets and limit themselves, experts say. The cells the scientists are talking about are actually known as AGRP (or agouti-linked peptide) neurons.
It is they who provoke negative emotions in a person and make him feel unhappy when he is not eating. When they break their diet, people simply try to turn off the neurons in question, which make the feeling of hunger even more unbearable.
The head of the whole study is Dr. Scott Stearnson. AGRP neurons are an ancient motivational system designed to stimulate individuals to satisfy their physiological needs, including hunger and thirst, explains Dr. Stranson.
He explains that the neurons in question do not actually push people directly to eat - they rather provoke a reaction to sensory signals that emit the presence of food. When a person is in an environment where there is a lot of food, it is very difficult to ignore this signal, which does not stop bothering him, explains the author of the study.
And if today these neurons interfere with a person to some extent, then in the past for our cave predecessors this system was extremely useful, said Dr. Stearnson.
