Discovered the neurological cause of obesity Source:

Cake certainly looks very tempting.

The Results of a study conducted at the brain Institute of the University of Virginia, tied up the pleasure center in the brain with the work of the circadian rhythm – the built-in biological clock of all living organisms on Earth. Delicious food, as you know, promotes the production of the neurotransmitter dopamine – a chemical in the brain associated with feelings of pleasure. In turn, the availability of tasty and high calorie food – and its excess – lead to a rise in obesity and the number of patients with cardiovascular disease and type II diabetes around the world. As found by the authors of the new study, intermittent fasting may be an effective way to combat obesity. But why?

When obesity has become a problem?

For the first 350 thousand years of existence of Homo Sapiens, our ancestors did not know about obesity. In those days there were few opportunities for long-term storage of food. Advances in canning and storage products were the real revolution. But progress does not always happen with the plus sign, we paid «diseases of affluence» (cardiovascular disease, diabetes 2). We are not biologically adapted, in order to obtain food, especially high-calorie.

The Authors of a recent study funded by the National Institute of General medical Sciences and brain Institute of the University of Virginia write that «the widespread availability of energy-dense, healthy food correlates with the rising incidence of obesity worldwide.» Team, led by Professor of biology University of Virginia Ali Guler, found a link between circadian rhythms and the pleasure center in the brain – it is this connection that is the driving force of obesity. Read more about what is biological clock, how they work and why this is important .

In the past people did not know when they will be able to eat next time, but today everything has changed. High calorie foods are saturated in sugars and carbohydrates, activates the pleasure center of our brains; good health – the biological signal to saturation. We feel satisfaction and then become addicted to this feeling. As Big Think, food companies have long exploited this fact. The ability to store food over a long period of time is relatively new and ensures that our next two dozen dishes just waiting in the kitchen.

Electricity has led to the emergence of refrigerators, lighting and, ultimately, smartphones that also play a role in this complex puzzle. Most of the time the Sun acted as a natural alarm clock, the people stood and fell with him. But things have changed and the work of our biological rhythms change, which negatively affects health. Constant use of phones also negatively affects the circadian rhythms, and lack of sleep contributes to obesity.

The situation is that the complete daily ration of calories can be Packed into a small volume, for example a cake or a sweet fizzy drink. Eat too many calories is incredibly easy, as overeating often leads to obesity and related health problems for life, write the authors of a scientific work published in the magazine .

What is intermittent fasting?

Easily Accessible high-calorie foods trigger the operation of the pleasure center, causing us to not only overeat during lunch, but snacking all day. This is one of the surest ways to gain weight, according to the study. Unfortunately, our body as fat is stored more calories eaten during break than during normal eating. But how to deal with obesity?

Scientists believe that a varied diet with large time intervals is good for health and it is natural for our species

One of the important ways of dealing with being overweight, as demonstrated by earlier studies, is intermittent fasting, which promotes weight loss. While there's some debate on the exact duration of fasting, it seems that a break of 10 hours between meals is beneficial to the body. Some researchers even suggested that a break of 12 hours will help to lose weight. The study authors noted that «humans evolved being in a constant search for food, but not anymore.

Overall, the study showed that the consumption of food is part of our genetic inheritance: if there is food, we eat. Compliance with a break of 10 hours between meals along with consumption of fewer carbohydrates can help millions of people maintain good health. It should be noted that the findings of this study do not should try to the entire population, as each organism has its own peculiarities of work before moving onon a new type of food, consult your doctor. Particular attention to the diet should apply to people suffering from diseases of the gastrointestinal tract.
