MrsTH a couple of thoughts - first, I did lose some weight whilst bfding, but not tons, but then again I had over 3 stone to get rid of. When I stopped bfding I lost a stone in a matter of days. This was after a year of bfding. Theory I believe is that when your body settles in for the long haul it wants to make sure you can always find the energy to make the milk. Dunno, but it was a huge difference. Should I have even said that - not a good enough reason to stop bf imo. Also, I've never had cellulite, til recently, and I always drink tons of water (at least 2litres a day) used to always have lecithin (can't remember which B-vit. that is) alot, and have gone back to it. Quite recently I read that it was one of the few supplements that really could make a difference. ? Worth a shot?
Finally, agree about the exercise and loads of water theory. But, don't feel overwhelmed by the idea of doing 3 hours... when I added up all hte pram pushing I was doing at as fast a rate as I could manage (v.heavy pram, v.heavy baby., lots of hills :-) it was about that a week... and still is. Although what used to take 25 minutes now take just under 15
So, to conclude (god I can waffle!)... I've lost over 3 stone, have just been measured/body fat etc. endlessly for a medical trial (no drugs, don't worry) and my fat/cellulite etc is really very minimal, although I'm still a small size 14 rather than my usual size 12 (but this is from an 18/20). TBH I didn't notice most of this happening as it's been so slow and whilst busy thinking about other things. Ony thing left is my tum, which is pretty much OK now, but needs lots of toning (that crepey look has nearly gone of its own accord) and I'm going back to pilates (swear by) next week..... all this has taken 18 months, but pretty much incidentally.
Having said all that, maybe my aims are a little lower, I don't feel the same urge to be sylph-like that I used to!
Good luck!
