根据13楼找到的解释：When because follows a negated verb phrase, it should be preceded by a comma when the because clause explains why the event did not occur. He didn't marry her, because she was frivolous means roughly, “Her frivolity was his reason for not marrying her.” When no comma is used, the because clause is understood as part of what is being negated. He didn't marry her because she was frivolous means roughly, “His reason for marrying her was independent of her frivolity.” 我觉得不是因为存在歧义，而是因为改变了原意。句子是想表达的是：年轻的女芭蕾舞蹈者和体操员常常不能保持好的饮食习惯是因为想尽可能的瘦的欲望，而E去掉逗号之后，句意就变成不是因为想尽可能的瘦的欲望才使年轻的女芭蕾舞蹈者和体操员常常不能保持好的饮食习惯。 TO BE DISCUSSED...
自己整理了一下
because
①看强调原因还是结果（逻辑）
②在gmat语法中，because of doing 出现一般为错， 正确的一般为 because of+ n. 同样 on account of doing 一般也错， +n. 正确。
③Wordy way to say "Because" 有以下几种： “due to the fact that,” “owing to the fact that,” “on account of,” and “on the grounds that,”
④当Because开头+代词（it/they）时，注意逻辑主语
