Sorry quiz, you are wrong -my BMI records me as not being obese and I'm size 16 and 5' 8". A lot depends on height and physical fitness, I have only got fat around my tummy, which is hereditary, and which I can't seem to shift despite eating less than 1000 cals per day for months. Apart from that my measurements are not far over a 14, which is slender for my height. I used to be a size 14 at 36" x24"x36" - but believe me I was skinny, I have the photos to prove it, and very desireable property in my hotpants! I think that natural ageing influences are being confused with self-indulgent-overeating here. You can't help the menopause, breast material turns to fat etc.. You get bigger - or some of us get thinner, we can't help it. It is quite different from the sort of person the original post was aimed at.
One size does not fit all.
