[Peter1948]

I agree that you can not legislate away people's vices. However some social attitudes can be changed. For example in Australia, many people accepted drunk driving as socially acceptable. That attitude changed with a campaign which included advertising, using the slogan that "if you drink and drive you are a bloody idiot." Now, some years later, very few people encourage their mates to drink and drive.
It seems that it is socially acceptable to have a fat belly.
Many people encourage us to do that. Some unknowingly teach us habits that tend to make us grow fat, by giving us sweets and foods loaded with sugar or corn syrup as a reward or a treat. They teach us to eat all the food that is on our plate. They get upset when we do not want to eat some special treat that they have prepared or purchased for us. They teach us by their example.
Food manufacturers can turn cheap ingredients into foods that they can profitably sell, and they invest money in advertising so their businesses can flourish. They teach us that their sugar loaded product is healthy. They omit to tell us that other alternatives are much healthier.
Many people believe that it is difficult to lose body fat and they use the scale as a measure of their progress instead of using other measures which would indicate successes. Most of the multi billion dollar diet and weight loss industry does not deliver on its promise of having us quickly, easily and healthily shed fat from our bodies.
Our environment does not support us, so we need to support ourselves and each other. We have an opportunity to be leaders and demonstrate the benefits of working towards having a healthy body.
I find the phrase "people of weight" very interesting. I have been at 92 kg for a few days now, though my waist measurement has decreased over that time and my trousers now fit me comfortably. Same weight yet not as fat.
