Wow, so let me guess you tried exercising for a couple months and did not see much and then gave up... Well try following your own advice and instead of assuming the art failed you, assume you failed the art.

Mind you, aerobic exercise does put me in better aerobic condition, sorta. It just doesn't have anything to do with weight loss.

Bullshit aerobics with proper dieting will make you lose weight or do you think you're somehow special? I would bet you either were not doing it right or gave up to quickly. You seem like a very sedintary person so it will take you a while to lose the weight. My personal guess is that working out is just not that important to you so grow up and admit it.

I have plenty of friends who do not have good metabolism but they have all suceeded in losing weight and keeping it off. Its only impossible if you do it wrong or you expect magic results...
