I see a point made above about obesity being linked to poverty.
It is not linked to poverty; it is linked to the piss-poor education that most people receive regarding food and its preparation.
You cannot tell me that it is cheaper to buy something form the chip shop or a fast-food chain, when you can buy low-carb, lean, high protein foods for such little money. What is boils down to is the fact that the parents of these poor, poor little children that I see walking around -- morbidly obese at the age of 10 or 11 -- cannot cook because they neither have the resources or the knowledge to prepare healthy food.
This extends to University, also. I know several dozens of people from a background I would call 'deprived' who just spend the entirety of their grants and bursaries either on alcohol or rubbish. While it sickens me to think that they are able to do this, it again boils down to education.
This will not change until the government or health authorities actually try to educate the masses on how to cook or prepare healthy food.
On the other hand, there are those fat ****s who just eat because they don't care about their bodies and for these people I neither have time nor sympathy. I am not trying to defend with my words above, either, because there is no excuse for anyone being obese or overweight in this day and age, but sometimes it is not the obese person who is to blame, or at least I don't think so, anyway.
