For me, breastfeeding seems to have been the best thing to help regulate my PCOS. I had
so much trouble getting pregnant the first time, but the second time it only took a month, and the third time was a total surprise.
Not that it's what you asked.
Generally speaking, I cut my calories but not too far. I try to stick to around 1800/day, and also try to exercise every weekday (who wants to exercise on the weekends?
). I started out just walking, a mile or two miles every day, and worked my way up. When it all comes down to it, I worry more about getting in my exercise than in my eating being perfect. I'd rather crochet than do just about anything, but I can put it down long enough to walk, though not so much so long enough to agonize over every bite going into my mouth.
I highly recommend Weight Watchers. Their @Home program is a hefty little chunk of change to shell out to begin with, but personally knowing I paid $140~ (deluxe kit plus express shipping) helps shame me into sticking with it.
Of course, the same program isn't for everyone; the important part is to find something you'll stick with.
Now for my routine caveat: Breastfeeding does not guarantee the weight will melt off, or that it will come off at all. We're all aware that expending more calories than we consume is what leads to weight loss, but biology throws a bump in the road for us nursing mamas. Sometimes--not always by any means, but sometimes--lactating women find that they lose weight only at a crawl if at all, and hanging on to the "last ten pounds" until Baby weans is not at all uncommon. Biology beats out mathematics any time.
