Age-related metabolic changes don't necessarily result in weight gain, as healthy habits play a crucial role. From adolescence onward, dietary choices and physical activity shape our adult physique.
Metabolism slows down
It is the sum of all the reactions that take place in the body in order to maintain its basic vital functions and expenditure on physical activity with the use of energy from food. Within these transformations we distinguish the value of the basic transformation of matter PPM, i.e. the body's need for energy conditioning the conduct of reactions enabling the body to function breathing, digestion. However, it is precisely this value of PPM that changes with age and consequently the demand for energy from nutrition decreases.
Loss of muscle mass
As the years go by, muscle size, strength and aerobic capacity decrease. The proper muscle content in the body not only determines the proper posture of the body, but also affects the level of metabolism and protects against disease. In youth we do not use all the muscle strength to perform daily tasks. It is estimated that the maximum muscle strength decreases with age by about 5% per decade, which is initially unnoticeable because it does not affect the efficiency of performing household functions.
It's a hormonal change
This problem affects up to 15% of men after 40 years of age and affects their body weight. The most characteristic symptom of this disorder is a decrease in muscle mass and an increase in the progenitor of fat, which leads to abdominal fat. However, changes in the body that are characteristic of this age are also caused by a reduction in the levels of active hormones in the female body, such as estrogen and estrogen, which are responsible for the growth of hormones (e.g. estrogen, estrogen, and esterol), which can increase the body's body weight after age 40.
