Have tried (well, probably a bit half-heartedly since STARVING most of the time) and failed to shift any of my extra (mumble) stones while exclusively BF.
Did manage to shift some after previous babies when BF finished but can't remember whether it is easier, harder or what. I'm hoping for a. lots of reassuring stories about it just melting off when you stopped or cut down, and/or b. some science to suppor this...?
For example, I just read (in New Scientist) someone saying that if you starve some animals, they put on weight cos the body becomes more efficient at holding fat and converting stuff into fat when under starvation conditions. Ha ha, trust me to turn this into a desperate explanation for extra blubber, but it does sound like a plausible evolutionary option to me
or perhaps I should just try to give up my chocolate habit now...
