Obesity is the result of chemical addiction to processed foods. Until you all understand and accept that, the problem will continue.
It is not just industry that produces processed foods. Grannies, good cooks, and food addicts all have the capacity.
We have the capacity, in the modern kitchen, to produce hyperpalatable foods. These are the problem. Just take flour, and flavor, sugar, seed oil. Or a bit of protein or fat, add wheat flour, sugar, flavors, fats, and what do we have? Hyperpalatable food.
The definition of hyperpalatable is food that we want more of, the definition of addiction.
