资料题：Which is NOT one of the medical advantages of losing weight for fat people（　）。

Doctors estimate that about 40% of women over thirty in Britain are overweight.This figuremay well be misleading as certainly large numbers of overweight people never seek medical advice.Mary women are very worried about being overweight.They feel that it shows a lack of will power or self-control on their part.In addition, fat women do not conform to (适合)the modem ideal of beauty exemplified by fashion models and young film stars who are all incredibly thin.Apart from aesthetic reason, there are strong medical grounds for not overeating.Overweight people are particularly prone to (易于)heart disease and are easily tired by physical activity.Losing weight would certainly make them feel healthier and increase their lifeexpectancy.Some women feel guilty about being fat and their guilt is repressed by eating more.it is a vicious circle.On the other hand, there are women who unnecessarily lose weight in order to conform to a model of social acceptability.Some of them end up by starving themselves to death!So perhaps it might be better to try to remove fat people's unhappiness than to try to remove the fat.
