Diet and exercise is futile if you want to loose weight in the long term. You will inevitably succumb to anemia and disease if your stress level isn't reduced. This means that you have to reduce pollution in your environment in order to be able to reduce your calorie requirement. You could try different exercises, eating higher quality more expensive food, but the results are marginal. Eventually your joints will wear out and there's only so many supplements you can take. Once you eliminate the pollution, your appetite should drop automatically.
