When I read on MN, and when I talk to people IRL, there's an underlying attitude to obesity that it is all down to willpower, or lack of, and individual choice over whether to be fat or thin. If we all tried a little harder and were disciplined, everyone could be their ideal weight.
I recently got on to reading some books on processed food, they are not new concepts, the ideas have been around a while. Lots of scientists and MDs from the US, where the obesity epidemic is a little further down the road than in the UK, have written about the addictive nature of processed food, books such as 'Wheat Belly', 'The Dorito Effect', Robert Lustig has done many talks on it. In the UK, Joanna Blythman has wrote quite a bit on the UK food industry.
Some have linked processed food to activating dopamine receptors in the brain so it works like other addictions. Yet cannot escape it once we walk into a supermarket, most of what is for sale there is very highly processed food. It's all sugar, salt, wheat, the bad fats (processed oils like rapeseed, not natural fats which are healthy). Flavours created by amazing scientists so you'd rather eat the flavour chemicals than the actual food.
Yet we are telling obese people, some of whom may be using food addiction to deal with past trauma, lifestyle stress etc, 'it is your choice, what you eat, you need to try harder, have more self respect, more willpower'.
I see obese people now as 'you are a victim of 'big food', the companies (only a handful of global billion pound companies) that produce and cleverly advertise and use supermarkets to sell this highly refined, highly addictive processed food'. If they were educated and told it's not their fault, they might decide they don't want to play the 'big food' game anymore.
