I think the second process is caused by overeating or overeating. Because the cause of obesity is very simple, in general, people get fat because they eat too much and exercise too little, which is caused by daily behavior not completely consuming the energy intake of our bodies, and the main source of energy intake is food, so overeating or eating too much will lead to obesity.
The third process of obesity is that women enter middle age. Because women slowly enter middle age, the metabolic rate in the body will slow down. After the metabolic rate slows down, there will be a lot of garbage in women's bodies. These rubbish may be fat or other substances. Over time, the accumulation of these rubbish will make us fatter and fatter.
To sum up, if we want to prevent obesity, the most important thing for us is to control our diet and exercise more. This is the best way to prevent obesity, because more than 90% of obese people are caused by lack of exercise, so if we can control our diet and exercise more according to our actual situation, then we can keep fit and get healthier and healthier.
