Earlier puberty for overweight girls?

[illusionofjoy]

According to an Associated Press article, girls who are overweight tend to start puberty sooner and become women who are overweight. Okay, that second point is pretty much a no-brainer, but I'm wondering what exactly the trigger is between fat and menstruation, should one actually exist.

Overall, I've noticed a frightening rise in the level of physical maturation in young girls over the years. I think something is wrong when a ten year old has breasts that are nearly fully developed. I don't remember seeing any breasts until 7^th or 8^th grade...but then again, I wasn't in much of a position or inclination to go "boobie-spotting" until my waning years of middle school anyhow.

In any case, given that a lot of these girls aren't fat, I'm more inclined to blame chemicals in the groundwater or something similar than just fat.

it's actually the hormones in meat. they feed hormones to meat so that it grows faster, and makes more meat. those hormones stay there, and we eat them.

there are girls who are menstrating at 7, now.

search out and vegetarian or vegan site, and they'll link studies.

Well...

In mammals it's mainly the fat percentage that the female is capable of retaining that kick starts puberty.
We're mammals that have evolved in very non-static conditions. Ancient humans were very susceptible to drought and famine. Therefore, nature decided that the best thing to do would be for the breeding age to drop in good conditions. So, chubby young girls become fertile earlier than their thinner counterparts... not only because the body thinks "Hey, now's the best time to make babies because they'll survive infancy!" but the female is more capable of physically being able to support being fertile at a younger age.

Now, as for the entire little girls with big breasts.. some of it is genetic. Hell, I was wearing a bra at nine and never got the chance to bother with a training bra, but I come from some very buxom women on my father's side of the family. The main part of the reason for girls maturing so early, and boys so late, anymore is the food supply.
American "agriculture" isn't even agriculture anymore, it's a corporation. And as a corporation it intends to glean the largest gross product and profit possible... now this means that they pump your meat, milk, and eggs full of hormones(bovine growth hormone, hormones to step up egg production, increase and expediate the growth of turkeys, hogs, chickens...etc.. and so forth and so on.) Every time you go to the store you're buying a cocktail of antibiotics and hormones. And it's not just in the animal products. You'll find it in your juices, your fruits and vegetables, your grain products.

Not sure if that'll help you any...
