I read your post up to "i've been doing this for 2 weeks already". Here is your problem. Do this for 6 months and if you still don't lose any weight, that is the time to question why!

Steve99 is totally right that you can't be impatient when it comes to weight loss. However, I would strongly recommend that you don't keep doing this in particular for 6 months. Lifting 2 pounds over and over and over isn't going to help you unless you have an injury, etc that prohibits more.

You are dedicating a lot of your time to exercise, which is good. That amount of time, though, is not necessary, and what you are doing in that time will not get you anywhere, now or 6 months from now.

Ask a trainer in your gym for some guidelines on getting you in the right direction on a program. While, ideally, a trainer would only develop programs for the people they can be with to monitor directly, in reality paying a trainer every time they walk in the door is not an option for many people. Which is why I, and many other personal trainers, will sit down with someone for a consultation (getting their health history, etc) and help them design a program they can do on their own, while checking in periodically. Check in your gym and see if they are willing to do the same.
