Don't you just love those types of comments!
I especially like when people remind me that "if you just eat less and work out more you will lose weight naturally. Have you tried that?"
I want to reply with "Wow, that is amazing! Where did you ever learn that? No one ever told me that secret knowledge before, you may be on to something here. Have you ever considered sharing your knowledge with the public? "
It's either that or send them to the throat punching ladies from one of the previous threads........that would take care of it.
