Have you ever wondered why Americans are always watching their weight,while the French,who often eat rich food,continue to stay thin? Now a report from Corell University suggests a possible answer.The study shows how life style and decisions about eating may affect weight.Researchers (研究者) find that the French usually stop eating when they feel full. However,Americans often stop when their plate is empty or they have reached the end oftheir favorite TV show.In fact,Americans are taught from an early age to“clean their plates”because children in poorer countries“are going hungry.”

According to Dr.Joseph Mercola,a health expert,the French see eating as an important part of their life styles.They enjoy food and spend a long time at the table,while Americ see eating as something to do quickly between the other daily activities.Mercola believes stopped.Besides，he points out that Americans drive to huge supermarkets to buy frozen（冷冻）foods for the week.The French,instead,prefer to shop daily,walking to small shops and farmer's markets where they can choose fresh fruits,vegetables,and eggs as well as high-quality (高质量的) meat foreach meal.

After a visit to the United States,Mirelle Guiliano,writer of French Women Don't Get Fat,decided to write about the importance of“restraint”-knowing when to stop instead of suggesting how to avoid food.Today she continues to stay slim and seldom goes to the gym.
