NEW YORK (Reuters)- Foods that fill you up without packing a ton of calories can help in the battle of obesity(肥胖), results of a new study suggest.

In the study, obese women who reduced the “energy density(密度)” of their diet by cutting their intake of fats and adding more fruits and vegetables lost more weight over a 12-month period, and felt less hungry, than those who simply reduced their fat intake.

“Adding low calorie-dense foods into the diet is an effective way of lowering calories and reducing hunger when you’re trying to lose weight,” Dr Julia A Ello-Martin said.

One of the reasons people don’t stick to a weight-loss diet is hunger. Ello-Martin and her colleagues guessed that a diet that controls hunger by encouraging dieters to fill up on low energy-density foods may improve adherence(坚持), as well as increase weight loss.

For the study, 97 obese women were randomly assigned to a group that was advised to decrease their intake of fats or one that was told to decrease their fat intake and increase low energy-density foods, particularly fruits and vegetables. Twelve months later, weight had come off the women in both groups. The women in the fruit and vegetable group, however, lost 7.9kg，in comparison to 6.4kg among the others.

The women in the fruit and vegetable group also experienced less hunger than the women who only reduced their fat intake, study findings show.

Although the study lasted only one year, Ello-Martin guesses the dieters may be able to keep their weight loss and dietary changes over a longer period.

“They are getting to eat foods that are helping them not feel hungry,” she said. “What’s more, the study didn’t have that unpleasant approach of having to count calories every day.”

B

As a boy，Sanders was much influenced by books about the sea，but by the age of fifteen he had decided to become a doctor rather than a sailor. His father was a doctor. So he was often with the doctors and got along very well with them. When he was sixteen，he was already hanging around the hospital where he was supposed to be helping to clean the medicine bottles，but was actually trying to listen to doctor's conversations with patients in the next room.

During the war，Sanders served in the army as a surgeon (外科医生). "That was the happiest time of my life. I was dealing with real sufferers and on the whole making a success of my job. " In Rhodes he taught the country people simple facts about medicine. He saw himself as a life saver. He had proved his skill to himself and had a firm belief that he could serve those who lived simply and were dependent upon him. Thus，while in a position to tell them what to do， he could feel he was serving them.

After the war， he married and set up a clinic deep in the English countryside，working under an old doctor who hated the sight of blood. This gave the young man plenty of opportunity to go on working as a life saver.
