Conversely, an inadequate diet can lead to fatigue, impaired decision-making, and can slow down reaction time. In fact, a poor diet can actually aggravate, and may even lead to, stress and depression. One of the biggest health impairments is society’s reliance on processed foods.
What happens to your brain when you’re anorexic?
Parts of the brain undergo structural changes and abnormal activity during anorexic states. Reduced heart rate, which could deprive the brain of oxygen. Nerve-related conditions including seizures, disordered thinking, and numbness or odd nerve sensations in the hands or feet.
What parts of the brain are affected by anorexia?
Overall, functional magnetic resonance imaging (fMRI) studies indicate altered neural activity across the brain, including the frontal, parietal, temporal and occipital lobes, as well as subcortical structures such as the amygdala, striatum, thalamus and the cerebellum [34].
What happens to your brain when you starve?
Restricted eating, malnourishment, and excessive weight loss can lead to changes in our brain chemistry, resulting in increased symptoms of depression and anxiety (Centre for Clinical Interventions, 2018b). These changes in brain chemistry and poor mental health outcomes skew reality.

Does your brain eat itself when you starve?
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.
What happens if you go too long without eating?
Harrison says skipping meals could lead to both nausea and diarrhea, and you could even become constipated. Similar to when you’re feeling anxious, the stress response released by the body when going too long between meals can irk the digestive system and make your bathroom trips unpredictable.

Can starvation cause psychosis?
During adolescence, however, when the developing brain is exquisitely vulnerable to insult, acute starvation may kindle a psychosis that takes on a life of its own. It is also the case that the delusions of a primary psychotic condition can lead to food aversions and initiate dangerous eating behavior.
