Adrienne, >Lately, I have noticed increased breast >tenderness and swelling exactly as if I was premenstrual (and NO, I AM NOT >PREGNANT). I'm wondering if the diet could cause this. When I went low-carb (and very close to paleo, by the way), my periods went from irregular to regular like THAT (snap). But I also noticed breast tenderness the first two or three cycles after my dietary changes. Now, nothing. Why? Good question! At least half of my periods were far enough apart that I was not ovulating regularly. My first thought was that with my periods finally the way they ought to be, my body was going through things it wasn't used to. But then the tenderness stopped. And you won't hear me complaining about that!
