I've recently started doing the 18:6 diet (where you don't eat for 18 hours in every 24). I'm actually sticking to it and seeing results. But... today I realised that fasting might muck up my cycles. Google doesn't really tell me much and what it does say mainly relates to 5:2 which I suppose is a bit more extreme and not as consistent so might have more of an impact on hormones. I've been ttc since January and have slightly irregular cycles already. I don't want to mess my fertility up but equally this diet is actually working for me and I'd like to drop 3 bmi points to be securely in the healthy band, which should in theory help fertility wise!
I asked within the 18:6 thread over on the weight loss boards, but it's not as busy over there. Any thoughts?
