I am lucky that this diet did not alter anything with my TOM, but yes, I have heard from many that it does.
Maybe it is a good idea to talk to your dr. about the birth control pill, since it might not work 100% while on this diet.
Started IP 06-30-11 @250lbs - Started alternatives mid Oct. 2011 - Stopped on Christmas 2011 (biggest mistake of my life) Lost 50lbs by then. Gained back all the weight I lost + 15 more lbs after IVF in 2013.
Many re-starts failed miserably. I stopped IP as I wasn't sticking to the plan but always try to re-start.
