Cesar, I think you're right that most people here are probably not running for weight loss, though I know people do come here with those goals. I have some e-mail evidence of that fact. I also do see people exercising, including running, with weight related goals. Very few with only goals only revolving around weight but some definitely do have goals of weight loss or maintenance. Personally, I just don't think people will stick with anything if they are only doing it for a reason like that. You also have to find an interest in it, which is why I often tell people to find something other than running. If they tell me they hate running but are doing it to lose weight or get in shape, my usual response is try biking, rollerblading, hiking, anything else. Find something you like. Otherwise, you will not stick with it long enough to lose weight and maintain your target weight.
