Sources and references for: Weight Loss Tips: Weight Which I Cannot Remove

Question:

I have gone up about 5 kilos, which seem to have come on secretly! I know all about intense slimming, diet, exercise, calorie consumption, etc. In theory it should be easy for me to remove this weight, but it isn't and it has become almost a fixation. If I could only stop thinking about it and do what I have decided to do, it would go away. But I think about it all the time, above all because I always feel fat. What shall I do in order to think sensibly? Have you any weight loss tips for getting rid of those final kilos?
