The difference is that people can't give up eating and there isn't the same kind of social stigma
That’s an interesting point about stigma Growstuff. At one time, if you didn’t smoke, you were considered odd. A friend who did nursing in the 60’s once told me it was virtually obligatory in nursing circles to smoke. I think the stigma attached to smoking only really developed after the ban came in, and people could feel the benefits of not breathing in other people’s cigarette smoke.
As regards obesity, I think there is stigma - or at least some obese people perceive there to be - and that is why the concept of ‘fat-shaming’ has arisen, and groups have proliferated online defending the right of people to be obese and calling out others who fat-shame people.
I agree people can’t give up eating, but they can modify what they eat and they can modify their emotional relationship with food.
But that takes courage and enormous effort and the desire for change, and I think public health campaigns which are often seen as hectoring or nannying aren’t really what motivate people.
