Physiological factors are one of the reasons for getting fat. When people reach the extreme of 30-35 years old, the functions of various organs in the body begin to decline, such as respiratory system and heart function, and the corresponding metabolism will also be affected. The consumption of body heat will be reduced, so that a large amount of fat can not be consumed, and it will mainly accumulate in the abdomen, buttocks and most parts. At the age of 30 ~ 80, 40% of the body's muscle mass will disappear, muscle fibers will decrease, and the remaining muscles will become weak. Similarly, the strength and quality of bones will lose 1% every ten years after the age of 30.

2. Dietary factors

Most housewives and mothers have the same problem. They didn't have time to eat until they took care of the children. At the moment, it's getting late and the body consumption is low, which is undoubtedly a huge problem for losing weight. Secondly, most thrifty middle-aged women are used to eating what their children haven't finished, and inadvertently eat too much. Moreover, some people feel full and always feel that their desire to eat is not satisfied. Moreover, international studies have proved that not being full will prompt the brain to direct our behavior and continue to eat.

3. Psychological factors

This refers to a comfortable life mood. After a woman gives birth to a child or gets married, her living environment changes and her mood changes. Most of them are happy, relaxed and comfortable. Over time, they tend to slack off and relax the strict requirements on their body before marriage, which is also one of the important factors of obesity.

Step 4 reduce the amount of exercise

With the increase of age, the activity and exercise amount of middle-aged and elderly people have decreased to varying degrees. For example, the nature of work has changed, most people have changed their jobs or retired to the second line, their lives have gradually stabilized, and their mental tension has also relaxed. Therefore, they eat more and eat more, and their intake virtually exceeds their needs, which will lead to obesity after a long time.
