American scientists have figured out how to reduce weight without diets and operations. It turns out that just turning off the sense of smell is enough! The results of the medical experiment are a new word in the fight against obesity.
We all noticed that during a cold, when we suffer from a runny nose, our appetite is noticeably reduced. As a result, we lose weight. “But don’t get sick with the flu in the hope of losing a couple of extra pounds?” You will be indignant, and you will be right. As it turned out, the connection between smell and weight is not so direct, but it still exists!
According to scientists from the University of California at Berkeley (USA), switching off the olfactory receptors in mice led to their weight loss. And this despite the fact that the experimental mice ate as much food as their fat relatives.
During the experiment, experimental animals with a “turned off” sense of smell lost 15% in a few weeks — and this was with the same diet as a group of their relatives with a normal sense of smell. Mice with “switched off” sense of smell did not eat less. It’s just that their bodies have become more active in burning fat. The experimental mice became more active and moved more, while their fat-eating relatives with a working sense of smell spent more time in a sleepy state.
During the analysis of the results of the experiment, it turned out that the organs of smell are directly connected with that part of the nervous system that controls the work of brown fat cells, in which the body burns excess energy. The conclusion is simple: if the olfactory receptors do not work, then they do not inhibit the activity of these cells. And it turns out that you can burn the maximum available amount of energy!
The research results were published in the medical journal Cell Metabolism.
“If our discovery is confirmed in human experiments, then we will be able to create a drug that does not block the sense of smell itself, but interferes with the work of those metabolic chains that are associated with it,” said Andrew Dillin from the University of California at Berkeley (USA).
This method also has a serious drawback: as it turned out, turning off the olfactory receptors increases the level of stress and workload on the heart. So while American doctors are planning to develop this method for people suffering from extreme forms of obesity. And these, according to WHO, are currently about 1/3 of the world’s population.
