The truth is that these beautiful faces and bodies often hide a, sad, unhealthy inner world. Some of these models are naturally thin, others have to resort to artificial and destructive means to be that way. Biological Factors Let's face it. Not everyone is naturally thin or beautiful. We may tend to be lean and muscular or we may tend to be heavy.
Some people are overweight early in life and become thinner later.
Some are thin most of their lives and experience weight gain later in life. Studies have found that there may be a significant hereditary component in developing eating disorders. People with a history of depression or alcoholism in their family are more likely to develop an eating disorder than those without such family history. While we cannot change our basic body type, we can work to have the healthiest body within that type. It's important to remember that bouts of purging, severe fasting, or excessive excercise can disrupt the body's ability to maintain a healthy weight.
