C) The HPA axis is subject to positive and negative feedbacks from circulating cortisol in order to restore systemic homeostasis.
D) After exposure to chronic stress, dysregulation of the HPA axis can occur and result in increased energy intake and altered macronutrient selection, towards more high fat and high sugar foods.
