- Neuroendocrinology : The study of the interactions between the nervous system and the endocrine system.
- Obesity : Excessive stores of body fat.
- Peptide hormone : A class of chemical messengers, secreted into the blood from endocrine cells, that bind to specific receptors expressed on the plasma membrane of target cells.
- Adipose tissue : Connective tissue composed of adipocytes, commonly known as "fat.
- Anterior pituitary : Endocrine gland that secretes hormones to regulate stress, growth, metabolism and reproduction.
- Arcuate nucleus : An aggregation of neurons in the mediobasal hypothalamus with important roles in appetite regulation and in the control of growth hormone secretion and prolactin secretion.

- Hunger : Localized subjective sensation, caused by emptiness and a resulting hypermotility of the stomach.
- Hypothalamus : A part of the mammalian brain located below the thalamus, forming the major portion of the ventral region of the diencephalon.
- Leptin : Hormone secreted by adipocytes that regulates appetite.
- Glucostatic theory of appetite control : The theory that changes in blood glucose concentrations or arteriovenous glucose differences are detected by glucoreceptors that affect energy intake.
- Melanocortins and appetite : The regulation of food intake through neuropeptides related to adrenocorticotropic hormone.
- Stress and appetite : The interactions between the hypothalamo-pituitary-adrenal axis and the regulation of food intake.
- Food reward : The brain mechanisms involved in reinforcing feeding behaviour.
- Gut-brain signalling : The interaction between the gastrointestinal tract and the brain.
