I don't remember many people publicising the dangerously fat being good thing until Dawn French started making it into a good thing some years ago, and then others followed suit. Rather than promote healthy eating she promoted her fat and made it acceptable.
Then dangerously thin became more common/publicised.
Normal doesn't exist any more. Fad diets are being shoved at us left right and centre, food is being tampered with, every few months something else is bad, salt, fat, now sugar. Low carb, low fat, gluten free as a fad not a need.
I come from a family that lives a long life, the background is plain and healthy food that hasn't been messed with, none of us have been seriously over or under weight. Look what happens when things get messed with, people get fat, people get too thin, people get obsessive about food and people get sick from it. I despair of it all.
Cosmo has always been crap, but people buy it, they also buy drinks with sweeteners and all the other crap, because it is there and it is promoted, they don't think.
