Social stigma of obesity is when people judge or criticize someone for being overweight. This can make someone feel bad about themselves and can even hurt their self esteem. It happens because some people think being overweight isn't healthy and that someone should try to be thinner, so they make fun of or talk badly about people who are overweight. This can really hurt people's feelings and make it harder for someone to be comfortable in their own skin. People should always be more respectful and understanding of everyone, regardless of their weight.
