The heat consumed by adults is utilized in three aspects: basal metabolism, activity and food thermal effect; Additional calories are needed for tissue construction during growth and pregnancy.
Many people confuse heat with internal energy. In fact, heat refers to the change of internal energy and the work done by the system. Heat describes the change of internal energy, which is a state quantity and a state function of the system, corresponding to a state point of the system. Fully understanding the difference between heat and internal energy is the key to understand the first law of thermodynamics.
In the process of heat transfer, the heat transferred between objects is related to the process, that is, heat absorption or heat release must be carried out in a certain process. When an object is in a certain state, it cannot be said how much heat it contains (heat is a process quantity, a change quantity).
In 2000, China Nutrition Society put forward the reference intake of dietary energy for China residents, pointing out that adult male light and moderate manual workers need 2400-2700 kcal of energy every day; The daily energy requirement of female light and moderate manual workers is 2100-2,300 kcal. Infants, children and adolescents, pregnant women and nursing mothers, and the elderly have different physiological characteristics, so do their energy requirements.
