To feel his food before eating could play an important role on how the body assimilates the calories, according to a new study published in Cell Metabolism.
In order to obtain these results, american researchers from Berkeley university have used gene therapy to mute the sense of smell in a group of obese mice. The scientists then realized that the mouse could no longer feel losing weight, in contrast to mice, which were still equipped with the sense of smell.
Importantly, the researchers were surprised to discover that the mouse is more thin, those who could not smell their food, ate the same amount of food highly in calories than mice not genetically modified. At the same time, the latter had however doubled in weight. And the mice who had had their sense of smell genetically tenfold were the ones that had the most fat.
“The senses play a role in the metabolism “
According to the team of researchers, to feel his food could, therefore, prompt the body to make reserves rather than spend it. They hope that these early findings could eventually help people who suffer from eating disorders, including anorexia due to age or diseases such as Parkinson’s disease. This could also help people who have trouble losing weight.
“This article is one of the first to really show that if we manipulate the data of smell, we can actually change the way donations the brain perceives the energy balance, and how the brain regulates this energy balance,” explains Céline Riera, the principal author of the study.
“The senses play a role in the functioning of our metabolism. The weight gain cannot only be measured in terms of the number of calories swallowed. It is also related to the way in which their calories are perceived, ” said The Independent, Andrew Dillin, professor of molecular and cellular Biology, and who participated in the study. “If we can validate these results in humans, may be can we create a drug that does not interfere with the sense of smell but is still able to short-circuit the metabolism. “
