The brain region known as the right insula also seems to be altered in people with anorexia. That bit of brain helps to process taste sensations, but it’s also involved in interoception, the ability to sense one’s own bodily signals. Those skewed body signals are the subjects of Zucker’s research at Duke.

Can your brain shrink from anorexia?
Cerebral atrophy — or what’s known as “starved brain” — is a common complication of anorexia nervosa and describes a loss of brain mass due to starvation.
Does anorexia cause permanent brain damage?
Brain scans of people with anorexia reveal that the brain goes through structural changes or abnormal activity during the disease. Some of these abnormalities may discontinue weight restoration, but some of the damage to the brain can be permanent.
Can not eating cause brain damage?
The human brain operates at a very high metabolic rate, using a substantial portion of the body’s total energy and nutrient intake (Sarris et al., 2015). Without proper nutrition to fuel our brain transmission and function, our brain is left vulnerable (Altomare et al., 2017).
When does anorexia become serious?
