Wants to lose weight

Do you know how much is a treadmill? I really want to lose weight.

They said overweight is one of the reasons I have difficulty in conceiving a child.
I want to go the the gym but I don't have time. I don't eat much but I'm still gaining weight. I tried the after 6 diet but it didn't work.

I really want to have a child now but I have to lose weight first. Do you have any suggestions?
