Why do people lie to you when they say im skinny but know fat?

* Social norms: In some cultures, it is considered rude to point out someone's weight, even if they are overweight. This may lead people to lie and say that someone is skinny, even if they are not.

* Body dysmorphic disorder (BDD): People with BDD have a distorted view of their own body, and may see themselves as overweight even if they are not. This can lead them to lie about their weight to others.

* Self-esteem issues: People with low self-esteem may lie about their weight in order to feel better about themselves. They may think that if they say they are skinny, people will think they are more attractive or successful.

* Eating disorders: People with eating disorders may lie about their weight in order to hide their condition from others. They may be afraid of being judged or criticized for their eating disorder.

* Medical conditions: Some medical conditions can cause weight loss, such as cancer, diabetes, and thyroid disease. People with these conditions may lie about their weight in order to avoid being questioned about their health.
