Hi there - pixie - if you get headaches - then maybe it's not for you?
I mean it is possible to lose weight steadily without any discomfort at all - so why put yourself through this? We have enough to put up with menopausally as it is!
The thing is I understand that much of the work on ADF is skewed towards males and is specifically looking at body weight and other related physiological responses. I have read ( and most of us know) that there are sex specific differences in metabolism due to our different hormonal make-up and control mechanisms, so one would expect the response to ADF to be different in women.
There is an article (quite technical!) here which suggests it could even be harmful - particularly for women of reproductive age.

OK not to believe everything on the internet but it is citing reputable scientific studies (some of which are done on rats!) which are linked to in the article and does not seem cranky to me - unlike some you read.
If you feel bad on it why not go for the lower fat option - like the Slimming World approach - I mentioned this on your muffin top thread. It is really easy and you do not get headaches, feel tired nor hungry!
Fine for those who feel OK but I've decided it is not for me - because maybe it is actually not good for women - whereas the slow but steady route can only do you good.
