If you want to think I live in a bubble because I don't jump up and down and point fingers each month when I see one woman mention she is underweight and has lost her period, that's your opinion. I think a lot of guys totally lose perspective when they are on this site.
Yep, my own personal powers of observation tell me that I really have only been seeing about 1 woman a month mention this, and it's usually in the context of "my pre-existing eating disorders" or "my longterm problems with amennorrhea". My powers of deduction tell me that would be about 12 women a year, providing of course each monthly post is by a unique poster, which isn't always the case.
That is not significant, especially since your classifying all of these posters as "struggling with low carb" is something you have chosen to do on your own in order to increase the count that are having difficulty because you think they ought to be.
