Food supplies energy for life maintenance. Carbohydrates, lipids, proteins, and alcohol are the main sources of energy producing, respectively, 4, 9, 4, and 7 kilocalories per gram. The maintenance of the ideal body weight is very important. Lack of energy in children and adults leads to marasmus and caquexia, respectively. Excessive ingestion of energy causes obesity, a severe disease that predisposes to several other diseases.
