Food restriction and excessive exercise enacted during anorexia leads to the depletion of glycogen (a form of energy storage), resulting in abnormal glucose metabolism and hypoglycemia (very low levels of blood sugar) (Mayo Clinic, 2018).
Does starvation cause hypoglycemia?

Starvation Ketosis During total fasting when there is complete absence of any caloric intake for several days, the resulting increase in ketones is referred to as starvation ketosis.
Why does insulin decrease during starvation?
Abstract. Starvation causes insulin resistance which is partly due to decrease of insulin action on glucose transport in target cells. Preliminary data from other authors suggest that starvation is associated with an increase of the time necessary for insulin to exert its maximum effect on glucose transport.
