With shoes & clothes on, I apparently now weigh barely 11 stone, a.k.a. 70 kg. Are there 14 pounds in a stone? If so, that's 154 lb. I haven't weighed this little in... 6 or 7 years?
But, you put that into a BMI chart, and I still come out with a BMI somewhere between 28 and 29. "Healthy", for someone of my height, is supposedly 50-60kg. The only time I've weighed as little as 50kg since becoming an adult was when I essentially had an eating disorder - denying myself food to punish bad behaviour. There's no way these hips could ever go down to 50kg without me being very unhealthy indeed.
And, even when I was a size 20, I had a 28" waist. I'm not sure what it is now, and being late for work means I need to get clothes on rather than faffing about finding a tape measure :)
