what I have noticed-moms weight and gender

[pinksapphire]

I think it's true that blanket statements are hard to make in terms of swaying (or anything, for that matter). But I definitely think (IMO) that eating in a NON-nutritional way sways girl. One can be heavy or thin and eat non-nutritionally so I think that makes the difference, not the way someone looks. I know this has been stated numerous times on here but it just really occurred to me this morning when I was thinking back to what I ate back then. We were just married & still very much into working out. Since we didn't have kids yet, we didn't make real dinners. We went to the gym after work and then just fended for ourselves together eating mostly fat free and/or sugar free stuff such as FF ricotta cheese, FF cottage cheese, FF yogurt, FF ice cream, etc. I also used to eat FF ricotta cheese w/ sugar free hot chocolate mix in it for snacks. Not very healthy and definitely not a diverse diet either!

I think it's more about losing weight AND doing it somewhat unhealthy. Most diets, you're still eating very well on!

Yes, that is exactly right. There is what biologists call a "U-Shaped curve" going on where both very thin and very heavy women tend to have more daughters and then everyone in the middle has more sons. There are many reasons why this may be the case, hormones, losing weight just prior to pregnancy, but the one I find very compelling is that being very heavy or very thin both reduce overall fertility and may sway pink because of that.

If everybody were perfectly healthy- nobody was too thin or too fat, I wonder if the ratio of boys would be much higher than even now? I wonder if in super healthy populations, there really are that many more boys born.

This may very well be the case but complicating matters is the fact that high sodium and high protein is actually NOT that healthy. There is much about the girl diet that is actually more healthy than the boy diet. I think it's more what the diets tell our bodies about the nutrients that are available in the environment, and not as much about healthy vs. unhealthy.
