Appetite suppression can be described as the experience of a distinct decrease in a person's sense of hunger and appetite in a manner which can result in both a lesser desire to eat food and a decreased enjoyment of its taste.[1][2] This typically results in the person undergoing prolonged periods of time without eating food.

Depending on the intensity, this effect can result in a sense of complete disinterest or even disgust concerning food. At times, it can often result in physical discomfort (such as Nausea) when attempting to eat food. In cases of severe appetite suppression, it is often easier for a person to consume liquid food, such as protein shakes, in order to receive the nutrition needed to function.

Appetite suppression is often accompanied by other coinciding effects such as stimulation or pain relief in a manner which can lead to feeling as if one either has enough energy to not need food or has enough anaesthesthia to not feel the pain of hunger. It is most commonly induced under the influence of moderate dosages of stimulant[3] compounds, such as amphetamine[4], methylphenidate,[5] nicotine,[6] MDMA,[7] and cocaine. However, it may also occur under the influence of other compounds such as opioids, psychedelics, and selective serotonin reuptake inhibitors (SSRIs). It is worth noting that if these substances are used for prolonged periods of time, weight loss often occurs as a result.
