answer: #Person1# wants to lose weight. #Person2# and #Person1# talk about how to lose weight effectively.
documents: #Person1#: I feel confused by all the diet options out there. I don't know which one actually works.
  #Person2#: Most of them are not so practical. It will be very bad for your health if you skip lunches or supers as the recommended. I think making an exercise plan can be more effective.
  #Person1#: Maybe you're right. It is very expensive to go to a weight-loss center. I'd better join in a fitness club.
  #Person2#: You don't need to lose weight, you are not fat.
  #Person1#: I bought an exercise dress yesterday and I found it was hard to dress it up.
