I admire one of my colleagues so much that I can’t stop watching her , although I am not a man . I remember she used to be fat . But after a summer holiday , she lost lots of weight . How could she become so slim in such a short time ? Now she is becoming more and more beautiful . She becomes so confident . She can dress any beautiful clothes now  .

I want to be as slim as her . Who can help me ? Except exercise and diet , what else can I do ? I doesn’t dare to use any diet pill . Are the pills useful and safe ?
