During her puberty, a woman's 3 major youth hormones are - insulin, cortisol, and estrogen.
They do everything needed to make her more attractive to the opposite sex.
They keep her thinner, prudent, dynamic, and loaded with energy.
But over time as a woman gets older, those same hormones begin carrying on more like a "jealous step sister".
This continues all the way up to menopause as it constantly cycles her body for pregnancy every single month.
It's her body's method of changing from "find a-mate" mode to "create babies" mode.
Which is excellent for building bodies that look good for making and protecting infants...
But it can turn into an absolute nightmare for the one who needs to look stunning at the sea shore or wants to feel good about wearing her number one dress on a night out.
