it is a metabolic process through which the body produces heat; it is composed of two parts, compulsory and optional adaptive thermogenesis. Compulsory thermogenesis is involved in the production of heat to keep the body temperature always constant around 37 and in the digestive and absorption processes of food induced thermogenesis from the diet. Facultative or regulatory thermogenesis is a process that is induced by external stimuli, especially cold and food intake. If this type of thermogenesis is to be increased, particular types of muscle contraction occur in the muscles of the whole body which manifest themselves as shivering and muscle tremor. This type of thermogenesis is under the control of the sympathetic nervous system which, through two hormonal mechanisms, increases the production of heat and allows the body to burn fat and calories. In some parts of the body the white adipose tissue is capable of transforming itself into brown adipose tissue, thus increasing the capacity to produce heat; this process is essential for maintaining a constant body weight. People with a normal weight have a greater thermogenic efficiency, while overweight people, having a greater quantity of white adipose tissue, use this fat as a thermal insulator and are advised to divide their caloric ration into many small meals. The basic metabolism represents the energy quantity necessary for the neuro-vegetative functioning to keep an individual alive. Factors affecting basic metabolic changes are muscle mass, lifestyle, nutritional style, muscle activity, age, sex, race and the specific dynamic action of foods. The energy consumed during physical activity varies with the individual's lifestyle and work habits, although energy consumption during physical activity depends on the subject's body mass.el soggetto.
