It can be challenging to understand why someone would make negative comments about your eating habits, especially when you are already in a calorie deficit and maintaining a healthy weight for your height. While I can't know your dad's specific motivations, I can offer some possible explanations for his behavior:
Projection: Sometimes, individuals who struggle with their weight or have their own issues with food may project their insecurities onto others. Your dad's comments about your eating habits might be a reflection of his own struggles and feelings of guilt about his weight.
Lack of awareness: Some people may not fully understand the concept of a calorie deficit or may have misconceptions about what constitutes healthy eating. Your dad's comments might stem from a lack of knowledge or awareness about your dietary choices and their impact on your body.
Concern (expressed poorly): Your dad's comments might come from a place of concern for your well-being, but he might not know how to express it in a supportive way. Sometimes, people resort to criticizing others, thinking it will motivate them to change their behavior.
Control issues: In some cases, people use food-related comments to exert control or authority over others. This can be a way for them to feel powerful or dominant in the relationship.
Cultural or generational differences: Some individuals come from cultural backgrounds or generations where commenting on someone's weight or eating habits is seen as acceptable or even encouraged. While this doesn't justify the behavior, it might help explain where it stems from.
Regardless of the reasons, it's important to recognize that these comments can be hurtful and potentially harmful to your mental and emotional well-being. If your dad's comments are impacting you negatively or contributing to feelings of stress or disordered eating thoughts, it's crucial to set boundaries and address the issue.
You could try having a calm and open conversation with your dad, expressing how his comments make you feel and asking him to stop making such remarks. If you find it difficult to talk to him directly, consider seeking support from other family members, friends, or a mental health professional who can help you navigate this situation and provide guidance on setting healthy boundaries. Remember, your worth is not determined by your weight or how much you eat, and it's essential to prioritize your well-being and mental health.
