I am not going to kick you so dont be afraid:

This is one of the few places where people actually support one another on the journey to health via weight loss via low carb dieting. Most of these forums are pretty crappy and this one is a good one.
The low carb plans we all use are really specific as to what we can and cant eat. Many folks cant lose weight any other way.
I too have lost weight without low carbing by just exercising and watching calories. Not everyone is so lucky. Now I am trying this method to keep weight off.
Like you said you dont have much to lose if anything, and the treadmill you just bought will get you there.-good for you!
If you decide to get rid of it I would love to get one myself!
The only insight I have to offer you is that the no pasta rice or other complex carbs have benefitted me incredibly. You probably dont need that program so enjoy the one you are on, and read what folks have to say here then chime in- good luck
