According to an Australian study, the stomach's mechanism for detecting how satiated we feel when eating is damaged in obese individuals , although the good news is that it recovers once we lose weight and keep it off. Specifically, Stephen Kentish and his colleagues at the University of Adelaide have published a study in the International Journal of Obesity that shows that the nerves in the stomach responsible for identifying fullness lose sensitivity after long-term consumption of a high-fat diet . To this is added that leptin, the hormone that under normal circumstances sends the signal of satiety to the brain, also works worse in people with a few extra kilos. "These two mechanisms combined make obese people need to eat more to feel full, which becomes a whiting that dies its tail", clarify the scientists.
Researchers say that this would be one of the reasons why people who lose weight during a weight loss diet tend to regain it quickly . In fact, it is estimated that only 5% of people who lose weight maintain their weight loss for at least two years, something that this new research could help to remedy.
