Episodic meal initiation: neuropeptide y, dopamine. Agrp: lateral hypothalamus: orexin a, b, mch. Anorexigenic signals: cart, amsh, paraventricular nucleus: crf. Emphasis that we are wired to overconsume. Biochemical: released by organs into the blood stream and then travel to their targets. Hormones travel a long distance, therefore it takes longer for signals to be received and requires a large amount of hormone to be released. Digestion and energy metabolism- phases of digestion of meal: cephalic. Sight, smell, taste, or thought of food. Stomach breaks down food: nutrient (absorptive) Absorption of energy and nutrients into the bloodstream.

Insulin is proportionate to adipose tissue: glucagon. Brain cannot make its own fuel, relies on glucose. Inhibition of fat breakdown in adipose (fat) tissue. Glucagon: facilitates the use of stored energy as fuel.
