In some special cases, the body needs insufficient energy. For example, when the body can't eat for a long time or consumes too much, after glycogen and stored fat in the body are consumed in large quantities, it will rely on protein decomposition of tissues to produce amino acids to obtain energy to maintain necessary physiological functions.
Extended data:
Human energy consumption has three main parts:
First, basal metabolism refers to the energy metabolism of the human body when it is awake and extremely quiet, which is not affected by mental stress, muscle activity, food, environmental temperature and other factors;
Second, daily consumption, that is, the energy consumed by normal activities such as eating, working and walking except lying flat, varies from person to person;
The third is exercise consumption, which refers to the energy consumption produced by one exercise.
When the total energy intake of an individual is greater than the body's needs, the excess energy is converted into fat and stored in the body. And losing weight is to let people consume excess fat stored in their bodies through exercise to achieve the purpose of slimming.
