The BBC has some good before and after pictures of people who lost weight in Britian recently.
Here's Lisa. She lost six and a half stone in six months. How many pounds are in a stone, you ask? The British have a strange way of stating their weight. There are 14 pounds to a stone. So Lisa lost 90 pounds in six months. Congrats to Lisa and the other eight successful people pictured there.
