In brief: It doesn't

Liothyronine is a form of thyroid hormone called t3 (liothyronine).
Unless you are truly hypothyroid, taking thyroid hormone to lose weight doesn't work because appetite is increased at the same time that metabolism is increased. You would have to be on a toxic dose of thyroid hormone before you would see any significant weight loss.
