Will power is of course important. My point is that it's far more nuanced than simply "stop eating so much". Quite plainly, if it was that simple there wouldn't be a problem. Additionally, "will power" is tremendously complex. We must recognise this and add it to the understanding that people are non-deterministic, complex creatures -- physically, mentally, socially, and metabolically. It's no more someone's fault they're fat than its someone else's fault they're lean. Genetics, epigenetics, in utero influences, disease, social factors, mental health, sleep.... they are all significant. In a time where personalised medicine is making giant leaps and grabbing headlines we should recognise that obesity and fat-related health and social issues are complex and sensitive, and require deep understanding.
