“We found that the areas of the brain that differed in the two study groups were the left insula, putamen and amygdala, which determine how rewarding a taste might be and how emotionally important it is. That information is then sent to parts of the brain that motivate eating,” said Ely.

Dieting can cause brain cells to eat themselves, a new study has found. In a paper published by the journal Cell Metabolism, US researchers report that tests on mice revealed that hunger triggers a process called autophagy in the hypothalamus.

This may be a result of altered brain chemicals, such as serotonin levels, which contribute to the dysregulation of mood, appetite, and impulse control in bulimia.
