In biology, this is typically done to provide heterotrophic organisms with the essential nutrients and energy needed for metabolism and physical growth, since they are incapable of acquiring nutrition and energy intrinsically like autotrophs and therefore must ingest external organic matters in order to survive. Animals, in particular, have evolved different forms of eating — carnivores and scavengers eat flesh (meat) from other animals, herbivores and algivores eat plants and algae, omnivores consume a mixture of both plant and animal matters, and detritivores and coprophages eat detritus and feces. Animals and phagotrophs eat and digest food internally, as opposed to decomposers such as fungi and microbes, who secrete enzymes to digest organic matters externally before absorbing the nutrients and thus do not "eat" food. For humans, eating is more complex, but is typically an activity of daily living. Human eating is usually organized into routine sessions known as meals, where proper courses of cooked food are consumed, typically with a decent quantity of staples; and more time-flexible casual eatings known as snacks, where small quantities of typically non-staple food (often convenience food, sometimes raw foods such as fruits and nuts) are consumed more for the purpose of degustation than to satiate hunger. Formal sessions of eating, e.g. in a gathering or a date, are known as dining, and large dining events where many people are invited to eat food together are known as banquets or feasts. The craft of preparing and presenting meals for formal eating is called culinary arts, and the person performing such tasks is known as a cook, chef or cater depending on the respective nature of food service. Physicians and dieticians consider eating a healthy diet essential for maintaining peak physical condition. Some individuals may reduce their amount of dietary intake, which may be a result of a voluntary choice as part of dieting lifestyle or as fasting for reasons of religious food prohibition, abstinence or political protest (i.e. a hunger strike). Limited consumption or rationing may also be due to logistical reasons such as a food shortage or a famine, in which case it will lead to starvation and undernutrition. On the contrary, overeating and excessive intake of calories (overnutrition) may lead to obesity and associated health problems, and while the reasons behind it are myriad, its prevalence in the developed world has led some public health professionals to declare an "obesity epidemic".
