During puberty, a woman's 3 main beauty and youth hormones - insulin, cortisol, and estrogen - treat her like a queen by doing everything possible to make her more attractive to the opposite sex.
They keep her slender, level-headed, vibrant, and full of energy.
But as time passes and a woman continues to age, those same hormones start behaving more like "evil step mothers".
This happens all the way up to menopause as they continuously cycle her body for pregnancy each and every month.
It's her body's way of switching from "find-a-mate" mode to "procreate" mode.
Which is fantastic for building bodies that look great for making and protecting babies...
But it becomes a total nightmare for the woman who wants to look amazing at the beach or feel confident in her favorite party dress on a night out.
