Our culture is opposed to obesity - it always has been.
Since the end of the war - rationing ensured that obesity was not an issue - we have seen ain increase in obesity across the western world.
Hand in hand with it is the cultural rejection of fat people who are routinely derided, scorned, assumed to be lazy, feckless, lacking in will power, lacking in self respect, and so on and so on.
I have always had issues with cultural 'role models', since the people saddled with such status rarely ask for it, or deserve it.
Interestingly, when we do find genuine role models, the media either ignores them, or takes a competely different tack altogether.
Amy Winehouse is a perfect example.
During her decline into death, she was routinely trampled on by the national press for her lifestyle, drug habbits, inability to perform, and so on.
What she should have been was a perfect 'role model' for young people.
Rarely have a have I seen a better template for the way in which drugs and alcohol can rob a young woman of her looks, her talent, and eventually her life.
So I do tend to side-step the notion of 'role models' as a media construct, which is what they actually are.
