Some people will say it's not my fault to eat too much, because I'm hungry. There are two kinds of hunger, stomach hunger and mouth hunger. Hunger in the stomach will not lead to obesity, because it really needs to eat, but hunger in the mouth is caused by psychological reasons. In previous psychological research, we know that there are several psychological factors that can lead to overeating: First, eating more can get higher social evaluation. This reason seems ridiculous, but I believe everyone has heard parents say to themselves when they were young, "Eating more is a good baby", which has induced children to overeat, thus forming a psychological complex that the more they eat, the more they will be praised, and it will continue to affect adulthood.

Secondly, food can be used as a tool to relieve painful feelings. When we were babies, it would be more satisfying to have a pacifier when we cried loudly. Therefore, subconscious food intake is associated with pleasant emotions, which has become a psychological stereotype with the passage of time. Moreover, scientific research has found that sweets can effectively improve people's mood. Therefore, it is not surprising that you can eat a big bowl of ice cream when you are in a bad mood. Moreover, ordinary people will eat less when they are anxious, while obese people will eat more at this time. Researchers speculate that this may be a bad habit of eating when you are in a bad mood. Because the facial muscle tension decreases when chewing, people indirectly feel the psychological tension decreases and their mood seems to have improved. Experts conducted psychotherapy on 40 obese patients accustomed to emotional eating, trying to make them interested in things other than food and get rid of the habit of solving problems with their stomachs. Results This method improved the effects of diet and exercise.

Third, too much work pressure can easily make people fat. Medical research has confirmed that long-term work stress is related to heart disease and metabolic syndrome. Relevant surveys show that the greater the work pressure, the greater the possibility of obesity. The survey results provide strong evidence for this theory, which proves that high-intensity psychological load during work is an important factor leading to obesity. In addition, the causes of obesity include subconscious fear of hunger. For all the above reasons, dieting is just a kind of self-restriction that is reluctant and contrary to the original intention. Even if weight loss has achieved initial results, it will collapse under the control of the dieter's will.

In addition to the psychological factors mentioned above, the cause of overeating may also be the hint of the environment. Psychologists have come to the conclusion through experiments that it is difficult for obese people to control their weight because they will eat according to uncontrollable external clues in the environment. In other words, the real reason why they eat is not out of actual needs, but the result of environmental hints.

If you put a fat man in hospital and keep him away from TV, magazines and other things related to tempting food, he will lose weight effectively and won't feel very painful. But once he returned to the real world full of supermarkets, restaurants and bakeries, faced with colorful food advertisements and hundreds of kinds of ice cream and cakes, his weight quickly rebounded.

Scott, an American psychologist, recruited a group of volunteers, including people with normal weight and obese people, and claimed that they were conducting other experiments, and then asked them to hand over all the tools that could see time. During the experiment, volunteers were asked to do something unrelated to eating. After that, they were told that the time was 5: 05. Then, the researchers divided the volunteers into two groups, each group including people with normal weight and obese people, and asked them to walk into two rooms respectively. But the clocks in these two rooms show different times, one is faster and the other is slower. When the actual time is 5: 35, the room with faster clock shows 6: 05, while the room with slower clock shows 5: 20. At this time, the researchers invited volunteers to eat cookies and recorded the number they ate. The results showed that people with normal weight in the two rooms ate almost the same number of biscuits, although they saw them at different times. On the other hand, obese people eat about twice as many cookies as those who see them at 6: 05. In other words, when obese people think it's time to eat, they will eat, whether they are really hungry or not.

Similarly, the study found that obese people are also very sensitive to the taste of food. The researchers invited the volunteers who participated in the experiment to taste ice cream indefinitely. There are two kinds of ice cream, one is high-quality vanilla ice cream, and the other is low-quality ice cream, which is a bit bitter. The results show that obese people eat more than low-quality ice cream that is not very delicious. But people with normal weight will eat something, which is not as obvious as obese people. Another experiment that studies the efforts of obese people and normal people to get food proves that obese people are more lazy to work to get food than normal people. Because in the experiment, it was found that among the two kinds of dried fruits with and without shells, 95% people were eaten by obese people, and only 5% people ate dried fruits with shells, but there was no significant difference in the number of people with normal weight eating these two kinds of dried fruits.
