The reason I started this WOE is because I quit smoking for 8 months and gained 30 pounds! I started smoking again (the weight was not why I started again) and couldn't take the 30 pounds off to save my soul. I had never had a weight problem in my life. I've been LC'ing since May 19 and have lost 11 pounds and almost 2 pant sizes. So, in answer to your question, smoking has not interfered with my WOE. Bad for you? Of course! Keeps you from losing? No.

Good luck with both,
Morgan
