In the last few weeks we have been devoting Sunday's entries to post documentaries or documentary excerpts with a view to helping intermediate students get acquainted with authentic material of the kind a native speaker may watch on TV.
These video clips come complete with a transcription or subtitles so that students can fully understand specific parts of the clip or the full clip for that matter. In doing so, we want to avoid the feeling of frustration the student sometimes feel when he/she manages to understand the gist of what is being said but fails to pick out some esential piece of information.
Today's video clip, Why are thin people not fat?, shows the first eight minutes of a BBC documentary, which was aired by the programme Horizon in January 2009.
At the centre of Why are thin people not fat? is a controversial overeating experiment that aims to identify exactly what it is about some people that makes it hard for them to gain weight.
