I downloaded the kindle version of Voltek and Phinny's book about low carb and they said in the beginning of the book that low carb may be more necessary during certain life stages than others. I haven't read the whole book yet so I haven't gotten to that chapter, but I'm pretty sure they're going to say that later in life it's probably very helpful.
I don't think I am menopausal. I'm 46. I had a hysterectomy in 2005 but they left my ovaries in. I noticed a large drop in hormones after the hysterectomy anyway. I have found low-carb to be very beneficial for me for losing weight and for just feeling great. I stay low-carb most of the time but I do try to have some higher carb days to pop up my leptin.
