According to Wikipedia, black people say that the word "thin" is not exactly the same as "thin". It is more used to describe that although a person is thin, he is not thin because of illness or malnutrition, but thin but muscular, showing a healthy figure. This "thin" form is usually obtained through healthy diet and exercise habits, not through dieting or other unhealthy weight loss methods. Therefore, the word "thin" is regarded as a compliment to a healthy and active lifestyle in black culture.
