If it was easy to lose weight, there would be no overweight people. It is very very difficult. It is not just a matter of eating less and exercising more. There are emotional reasons that people eat, differing hunger levels and peoples ability to cope with that, the way they were raised, metabolism etc. It is so much more complicated than people think. I think one of the main problems is that we all buy food from supermarkets. If we shopped at the wholefood shop and dug veg out of the garden, we would be fitter and healthier I am sure. All standard foods are processed and laced with sugar and fat which add to our taste and desire for them. If those foods were eliminated and the government had stricter control over processed foods in supermarkets, people would eat healthier and more filling and nutritious food.
