Appetite is another sensation experienced with eating; it is the desire to eat food.
Appetite is the desire to eat food, sometimes due to hunger.

Leptin

leptin resistanceLEPlectin
Leptin, a hormone produced by adipose tissue, acts as hunger suppressant.
Leptin (from Greek λεπτός leptos, "thin") is a hormone predominantly made by adipose cells and enterocytes in the small intestine that helps to regulate energy balance by inhibiting hunger, which in turn diminishes fat storage in adipocytes.

Sense

Hunger and satiety are sensations.

Neuropeptide Y

NPYneuropeptide Y (NPY)neuropeptide-y
CCK is key in suppressing hunger because of its role in inhibiting neuropeptide Y. Dopamine acts primarily through the reward centers of the brain, whereas serotonin primarily acts through effects on neuropeptide Y (NPY)/agouti-related peptide (AgRP) [stimulate appetite] and proopiomelanocortin (POMC) [induce satiety] neurons located in the arcuate nucleus.
Subtypes Y1 and Y5 have known roles in the stimulation of feeding while Y2 and Y4 seem to have roles in appetite inhibition (satiety).

Cholecystokinin

CCKpancreozymincholecystokinin (CCK)
The hormones insulin and cholecystokinin (CCK) are released from the GI tract during food absorption and act to suppress feeling of hunger.
It participates in a number of processes such as digestion, satiety and anxiety.

Hypothalamus

hypothalamicanterior hypothalamushypothalamic hormones
The arcuate nucleus of the hypothalamus, a part of the brain, is the main regulatory organ for the human appetite.
The hypothalamus controls body temperature, hunger, important aspects of parenting and attachment behaviours, thirst, fatigue, sleep, and circadian rhythms.

Eating

Hunger represents the physiological need to eat food.
Physiologically, eating is generally triggered by hunger, but there are numerous physical and psychological conditions that can affect appetite and disrupt normal eating patterns.

Stomach

When hunger contractions start to occur in the stomach, they are informally referred to as hunger pangs.

Emotion

Emotional states (anger, joy etc.) may inhibit hunger contractions.

Diabetes

Levels of hunger are increased by lower blood sugar levels, and are higher in controlled diabetics.

Muscle tone

Hunger contractions are most intense in young, healthy people who have high degrees of gastrointestinal tonus.

Gastrointestinal tract

Hunger contractions are most intense in young, healthy people who have high degrees of gastrointestinal tonus. Later studies showed that appetite regulation is an immensely complex process involving the gastrointestinal tract, many hormones, and both the central and autonomic nervous systems.

Insulin
