The first time I tried the Atkins diet in 1998 or so, it was to see if it could help my PCOS. I was hairy, fat, depressed, had acne all over my back, and almost never got a period. After one week on the Atkins diet I got my period. So I would take that as absolute proof positive that Atkins works for PCOS, and that we should be on it, and stick to it.

Unfortunately, I didn't stick with it at the time, instead I persuaded a doctor to put me on Metformin, which has I guess about the same effect as being on the Atkins diet. Metformin made my acne go away, and regularised periods but did nothing for the body and facial hair, or didn't seem to do much. Now I'm back on Atkins, but I can't tell if it has any effect on my PCOS because I no longer have a uterus. I do, however, still have my ovaries.
