Most people would like to have an attractive physical appearance, but some people become very worried about the way they look. This can sometimes lead them to do things that are unhealthy. For example, many women believe that they must be very thin in order to be attractive. They see pictures of fashion models who are very thin and then believe that an attractive woman must look the same way. However, many men prefer the appearance of women who are not so thin. In order to become thin, some women try to reduce the amount of food that they eat. When this is taken to an extreme, a woman might eat far too little food to remain healthy. Her weight may become dangerously low, as she tries to become thinner and thinner. This condition is called anorexia, and it affects many thousands of women in Western countries. Anorexia is one of several conditions known as eating disorders. Another eating disorder is called bulimia. A woman who has bulimia will sometimes eat large amounts of food, but then will try to eliminate the food, by vomiting. This is intended to prevent any weight gain, but it is also a very unhealthy behavior. Unfortunately, some women are concerned about being very thin, but some women have different concerns related to the appearance of their body. For example, some women believe that their breasts are not large enough, and will undergo surgery to enlarge their breasts. In this surgery, some artificial substance is implanted inside the breast to make it larger. Many women have had this surgery, but many of them have suffered serious health problems as a result. In recent years, many men have also become very concerned about their physical appearance. For example, some men believe that they must become very muscular in order to have an attractive appearance. To achieve this appearance, some men use drugs called steroids, which make it possible to gain large amounts of muscle. However, steroids can have very unhealthy side effects. In addition to drugs, some men have used surgery to change their physical appearance. For example, some men have had implants to make their arms, legs, or chest appear larger. It is unfortunate that so many people feel so unhappy about their physical appearance and that they do unhealthy things to change the way they look. Of course, everyone should try to be healthy, but people must also learn to accept their physical appearance. Many different body types can be attractive, but there is no single ideal body type. There is no need to use unnatural methods of changing one's body.
