I just started taking Metformin to help treat PCOS and all the issues that go along with it. My husband and I would like to have a baby soon, once my hormones normalize and I lose weight. I am doing my best to follow a low-glycemic diet and have started exercising. Although I intend to follow a healthy diet for good, will I have to avoid occasional favorites like fried fish or watermelon or a hamburger forever? I don’t eat those kinds of foods often, but at family cookout and such those dishes are prepared and if I can never again eat food I actually like… I would rather just come to terms with that now.

im not sure about the metformin but you can eat whatever you want as long as its in moderation .. and one offs are no harm as long as they arent to regular .. http://www.calorieking.com is really good .. also just look for low fat low cal recipes theres plenty out there that are very yummy .. good luck with TTC ..

I am also on Metformin. I don’t actually watch what I eat, just the amount. I have yet to start exercising, frankly because I am lazy, but I will next week. We are also TTC and my OB told me to lose just 10% of my body weight and that should help considerably.
As far as being on Metformin forever, that is up to your doctor and you. I think that msot women with PCOS go off the Metformin around 13 weeks pregnant. Not sure what your doctor will do because I do not know if you have Insulin Resistance. Having IR may require you to be on it forever because that is the start of adult onset diabetes.
Good luck to you.
