It aired at around 8 pm on Slice (I think). The woman, Jennifer, was a former model (she was absolutely gorgeous even with some extra pounds on) and she was determined to lose 66 lbs and return to modeling (as a plus sized model).
(Eventually, she lost about 40 lbs and got an engagement through a model agency, although the contract stipulated she had to remain a size 14.
It was an interesting episode to watch (I try to watch every single one) - I was somewhat miffed by her boyfriend who seemed to be a bit unhappy about the fact that she decided to accept the contract and not lose any more weight. But more importantly, I was quite shocked to hear that size 12 is already considered a plus size (HELLO!!!), although they did say that most plus sized models are a 14 or a 16.
It's amazing how many inches the women on the show usually shed. It is nice that they give us the measurements, as weight itself sometimes is not a good enough indicator. Jennifer was the same height as myself (5'9") and I had to laugh at how differently we were built. Her original measurements were
45.5-40-49 (if I remember correctly) while my measurements were (when I took them on Feb 1) 46-45-46 (obviously, my waist is non-existent).
