The reason for losing weight quickly (in a not very nutritious way!) is related to the Trivers Willard hypothesis, whereby your body will think 'times are hard' and that resources are limited if you're doing this and, hopefully, will 'want' you to conceive a girl because a girl needs less resources to raise and produce grandchildren.
The low-everything diet Atomic devised also advises restricting protein because protein helps your body to build testosterone and for conceiving a girl we want lower testosterone (the idea with being your lowest ever adult weight is that you're guaranteed to have lower testosterone than you ever have because you'll have less muscle - if you've lost in this manner).
Thirdly, it's been proven that for a girl conception you want your blood sugar levels to be low - so no breakfast and no snacking - and 2 or 3 spaced out meals only.
I just saw your siggy, I'm so sorry about your little boy x
