The course is well designed to give a very short introduction to a very complex topic. Week 1 looks at environmental influences and learned behaviours which influence eating patterns. Weeks 2 and 3 look at biological factors: the role of hormones, the nervous system, genetics and epigenetics. As someone who last studied biology in school years ago, I found these two weeks challenging but very interesting, and look forward to following up this subject in the future.
A couple of minor problems could be ironed out to improve future courses, eg making the various diagrams available as slides to download rather than simply displaying them behind the lecturer.
