there is no scientific evidence to support the claim that victims of narcissists specifically grow fat as a direct result of their experiences with narcissistic individuals. It is essential to avoid making broad generalizations or assumptions about physical changes based on someone's emotional experiences or interactions with others.
Weight gain can result from a wide range of factors, including lifestyle habits, genetics, stress, emotional eating, medical conditions, and more. While stress and emotional difficulties can impact a person's eating habits and lead to weight changes, it is not accurate or fair to attribute weight gain solely to interactions with narcissists.
It's crucial to be cautious about perpetuating stereotypes or stigmatizing individuals based on their experiences with narcissists or any other psychological challenges. If you or someone you know is struggling with emotional issues, it is best to seek support from mental health professionals who can provide proper guidance and assistance.
