Recently, we received a male patient in his twenties with “distracted and addicted to the Internet” as his main problem, and in the process of treatment, we came to know his family. He is the oldest son in the family and has a younger brother of 10 years old. The patient said that his brother also had some emotional problems, such as temper tantrums and reluctance to communicate with others. However, the two behaved very differently in terms of eating: the older son was unable to control his eating and was overweight and obese, while his brother was eating less, and the more his parents persuaded him, the less he ate and was very thin. This family, the parents are demanding of their children, from childhood education is relatively strict, but in terms of life and excessive concern, especially the mother, the child care is very fine, tea and water, every day from the wake up nagging, the child if not listening, the mother will lose her temper, although the children are older, the mother has not changed much, so that the two sons are very annoyed. Both sons are bound and tied up by their mother’s love, and are struggling with their mother through eating. The difference is: the older son shows it by giving up on himself and not controlling himself, while the younger son uses excessive control of himself to avoid his mother’s control. Having more clinical contact with eating disorder patients, I know that eating disorder patients often fight against their parents for their control by controlling their own eating behavior. It seems that this approach is not only used by patients with eating disorders, but it is possible that many children who are harshly bound by the love of their parents also use it, just in a different form. For example, in this article, two children in the same family are using different ways of eating, both expressing rebellion against their parents. Therefore, if a child eats too much or too little, as a parent, it is important to reflect on whether there is an emotional problem mixed behind this abnormal eating behavior of the child, especially resistance to the parents. In the parent-child struggle, food sometimes becomes a tool in the child’s struggle, and the dinner table is the battlefield. However, how many parents are able to recognize this problem?
