We know that one of the things that can trigger the onset of puberty , in particular in females is that when enough body fat accumulates that body fat releases a hormone called leptin . And that hormone leptin travels in the bloodstream across the blood brain barrier and goes to the hypothalamus and can trigger the onset of puberty by activating the neurons that release gonadotropin releasing hormone .

And that hormone leptin travels in the bloodstream across the blood brain barrier and goes to the hypothalamus and can trigger the onset of puberty by activating the neurons that release gonadotropin releasing hormone . So many people believe that one of the reasons that puberty is happening earlier and earlier in females is because of the accumulation of more body fat at younger ages than was observed 30 or 40 certainly 100 years ago .
So it is indeed a crisis because it has enormous detrimental effects for so many aspects of , of uh brain and body health and longevity . But this whole process of thinking about body fat signaling leapt into the hypothalamus and the onset of puberty doesn't necessarily have to do with the obesity crisis . It might relate , but it could also relate to , for instance , improved nutrition , which is allowing body fat stores to accumulate , maybe not to the level of obesity but to accumulate earlier and at younger ages and females which is then causing earlier puberty in females to just highlight how that might be possible .
And yet , I don't think we can conclude that at all , something is happening . However , it could be increased body fat stores due to overeating and obesity . However , it could also be unrelated to obesity .

I want , I want to review some data to talk about the onset of Menzies menstruation that is puberty in females according to country and according to age over the last 100 or more years .
