How much weight did you loose while breast feeding ?

I've heard it helps you shed baby weight and i've also seen some amazing results by many women that breast feed but then again they were super thin before getting pregnant :/ I was wondering did anyone else that wasnt so " small " manage to get back to their weight they were before getting pregnant ? anyone can comment how much they lost you don't have to put your weight if you don't feel comfortable with it but do share how much you lost and were you happy with it
