Snorting fatty foods can make you gain weight
When you walk near restaurants with outdoor areas in the summer, smelling delicious smells barbecue or hamburgersthen you can’t imagine that even this way you can… gain weight.
An experiment conducted by scientists at the University of California Berkeley showed that the sense of smell strongly influences the brain’s “decision” to store fat in the body or burn it.
True, so far the experiment has only been carried out on mice, but the researchers say that its results are quite applicable to humans.
So, scientists Andrew Dillin and Selina Riera studied groups of mice: normal mice and those whose sense of smell was temporarily blocked – and eventually saw a direct connection between the presence of smell and how quickly the mice gained weight.
All mice ate the same, but those that sniffed fatty foods gained heaviest weight. In contrast, initially obese mice whose sense of smell was blocked lost weight, although they were not “on a diet.”
“Research shows that external stimuli, such as smell, can influence brain functions related to metabolism.”says Selina Riera. “Perhaps in the future, people who struggle with obesity could temporarily block their sense of smell to burn calories faster.”.
But of course there is also risks. Firstly, people without a sense of smell fall into depression faster. depressionbecause they lose the pleasure of eating. Secondly, in mice without a sense of smell there was a significant increase norepinephrine hormone – a stress response from the nervous system that can lead to a heart attack.
“Removing a person’s sense of smell is, of course, a radical step, but it could be an alternative for those who are struggling with obesity and are considering gastric banding or reduction.”adds Dillin.
But, according to the scientist, to use this method, it is important to know exactly how much olfactory neurons need destroy, and how often, because once the sense of smell returns, the weight may also return. Research in this area will continue.
