Friend's weight loss succes

A friend of mine continously lossing her unwanted weight. She was at size 12 few months ago and right now she went back to a size 5. For me its unbelievable knowing that she loss weight that fast. Everybody really applaud her for doing such an awesome job. We were even wondering how she did it beside taking healthy diet pills knowing that each and everyone of us have different issues and stories regarding how diet pills work. She must have the best diet pills. I'm just happy for her weight loss success.
