　　Is Dieting Good or Bad?

　　In order to keep a slim body and to be more attractive in appearance, many people, especially girls, would like to lose weight by eating less. Some people worry that dieting is bad for our health, while others don't agree. In my opinion, dieting is not good for most people.

　　First, dieting is harmful to people's health. It has been proved that if one begins to eat less to keep slim, he or she will be much weaker than those who don't. Young people's bowels must work in an orderly way everyday. If a 20-year-old girl eats less than what her body needs, her metabolism will slow down because there is not so much food to be digested each day. As a result, this young girl will become both physically and mentally slow as a 40-year-old one. How terrible it is! Second, dieting may affect our lives. In this modern society, people need to be very energetic to face severe competitions in their study or work. Dieting will surely reduce their energy and in turn affect their lives badly.

　　In conclusion, I believe that dieting is not advisable for most people, except for those who are told to do so by doctors.
