My intro with a question

Hello! I'm kind of in the in-between stage of 2nd tri and 3rd tri.  I'm not officially switching over here for another week or so.  I'm 22, a SAHM hoping for completely drug free birth.  Planning to exclusively BF and CD.  My DH and I have been together about 4 years and we're expecting our first son end of july/beg of Aug.  My EDD is Aug 8th but for some reason i'm thinking Aug 15th is going to be the day.

So heres my question:  Whose thinking about weight loss plans already?  Whats safe/ not safe while BFing.  I did weight watchers in the past and lost over 30 lbs in 6 months without exercise.  This time i'm going to want to lose like 80 lbs.  If I only eat popcorn for a meal or a can of green beans is that going to affect my milk supply at all or will I be good no matter what I do since I take prenatals?

ETA:  Any post partum weight loss success stories would be great too!
