I understand what you mean and most people might do exactly as you say, I don't argue with that. My argument is that it is possible to lose weight if you do sports, even if you lose a very small amount of weight, it is still losing the weight. I'm not trying to stubbornly prove my point here, I just feel that I've been misunderstood. I don't advice anybody to leave doing what they are doing and start doing some sports because it is the only way to lose the weight, no it isn't. There are lots of other options and maybe more effective even. I just don't understand why we should deny the fact that sports also is one of the options, if, and I have to agree here, combined with a good diet (and by diet I don't mean starving yourself, but eating consciously).
I appreciate your answer, there is more for me to read and learn about the subject indeed.
