I think something important to take into account is the contestants are morbidly obese, whereas you are a normal weight. They may be retaining some water from sore muscles, but the fat loss is great enough to basically cancel it out.
I'm the same way as you mentioned, without fail the scale goes up when I weight train and get sore -- especially the less I weigh!
