In particular, Stephen Kentish and his colleagues at the University of Adelaide have published a study in the International Journal of Obesity, which shows the nerves of the stomach responsible for identifying that it is full to lose sensitivity after consuming a diet high in fat in the long run.
To this is added that leptin, the hormone that normally sends to the brain the satiety signal, also works worse in people with a few pounds more. “These two combined mechanisms make the obese need to eat more to feel full, which becomes a snake that is death tail”, clarify the scientists.
The researchers say that this would be one of the reasons why the people who lose weight during a diet tend to recover it quickly. In fact it is estimated only 5% of those slimming maintain weight loss for at least two years, something that the new research could help remedy.
