Extended Matching Questions - Weight loss (Level of difficulty=EASY)

This is an easy one and probably not very representative of the level in the exam according to one of my sources . Unfortunately, I have not been formally trained to write multiple choice questions for the RACGP.  It is certainly more difficult than I thought.  However, it may still have some value as it can at least give us some idea of "What is an extended matching question?".  Will try and write some more difficult ones down the track.  If you like to give us feedback on our questions, good or bad, please do so in the comment section or email me.  The main aim is to learn, teach and help each other.  I will also try to get RACGP to give us some sample questions if possible.
