I'm still "overweight" according to BMI but my waist is under 30" (which is half my weight in inches - the "dr oz" healthy waist size) and my body fat percentage is now 29% which is in the "acceptable" range. I want ALL the indicators saying I'm a healthy weight though, so I'm gunning for that BMI - I'm in the "normal" zone when I hit 127. Interestingly though, the lower end of "normal" for someone my height is 95 lbs, and I have over 95 lbs of completely lean body mass, so I'd not only need to lose every speck of body fat I have (which is impossible, and it's really, really unhealthy to go below about 12% for a woman) but I'd have to lose some muscle as well, to hit that. If I don't put on any extra muscle, at 127 lbs I'll be at 24% bf, which is close to where I want to be anyhow (I was aiming for 20-25%). So for me, the upper end of BMI-good is definitely the place to be.
I think an Imbolc thread would be a great idea.
