Can’t stop eating unhealthy food? A new study explains the reasons

Losing weight and starting a diet It is not always easy, the reality is that there are many aspects involved. In principle it is important select the dietary pattern that is suitable for every lifestyle, second and probably one of the more fundamental questions, to achieve good results is willpower.

The truth is that for many people it is difficult to control the temptation to eat unhealthy food O junk food. A new study provides a new and interesting context about this topic, especially after years of eating this type of foods harmful to health. The reality is that at this time there are not many foods that escape from containing a high in fat and calories, after all supermarket aisles Y the menus of most restaurants they are saturated with these kinds of options. Recently it has been verified that even those people who have access to optionnutritious food, may present difficulties to consume them regularly.

Based on the above, a new study suggests that this challenge can be attributed to the way the brain responds before certain foods. Saying research work was published in the Nature magazine and explored how a high fat diet affects the brain, and as a consequence also it alters the desire to eat healthy foods. The researchers focused the study on mice, thus giving one group a high fat diet (HFD) and to another group a standard diet (SD). After a few weeks in general, it can be said that the mice stopped eating the SD diet model, after they were offered the high fat diet and when the latter was removed, the mice strangely ate very little of the normal diet. As a result, the mice lost weight.

As an important and complementary part of the study, the scientists also recorded the activity of AgRP neurons, which is a group of neurons that control the energy balance and they are activated when you feel hungry. In the same way they were monitored dopamine neurons, the neurotransmitter responsible for our state of mind and make us feel good. What did you find? After the mice ate a high-fat diet, they experienced a reduction in the responses of both groups of neurons when exposed to SD. So much so that neurons only responded strongly when the HFD was offered. In other words, the mice found that the standard diet era less satisfying and less rewarding than the food that had more calories and fat.

Without a doubt this explains beyond the simple cravings, the reason why on many occasions it is difficult to stop to eat junk food. At the same time, another of the most interesting conclusions of this study is that the mice experienced abstinence from fatty food, which they interpreted as a eating habit that in the long term makes caloric foods they become irresistible to the brain, since it processes them as more rewarding and valuable. The most interesting thing is that they are very attractive, even when we are not hungry.

We can conclude that the brain has memory, in such a way that a recurrent consumption of fast and processed foods, creates a habit / habit in the body that damages not only the health and optimal functioning of the organs, alters brain chemistry and the hormones responsible for regulate appetite, hunger and even mood.
