Even assuming that your contention that the body loses weight coincidental with dying is true, that is far from evidence that that the loss of weight represents a spirit leaving the body. That is to say, there is ZERO evidence that the weight loss is due to a spirit or soul fleeing, regardless of how much you want that to be the case.
