Forget about the hip-waist ratio! At least for health purposes. (I understand that there is a definite attraction-factor in more noticeable hip waist ratios
.) (I like Marilyn Monroe's shape too!) But many health markers and so on don't take into account the hip-waist ratio any longer, but do the waist-height ratio, as there is so much human variation around the hip-waist thing, and so it does not always apply.
I am not a natural with numbers, but I lamented to Mr Svea about the fact that even though my hips and waist were declining, back when they were diminishing rapidly, the ratio was not. Well, when you are slim hipped as you are (and I am absolutely too), this is what is going to happen! So said Mr Svea, who actually likes numbers and ratios and so on. Ie the ratio might never change, even though your waist size does get smaller with weight loss. (That is basically my situation.) So I have ignored that figure and been perfectly happy ever since. But the waist-height ratio is a far more satisfying a health marker for we slim-hipped women. (And applies to men too of course, so even more a convenient health marker.)
