One study showed fat women who intentionally lost at least 15% of their body weight were over two times higher risk of death compared to fat women who remained weight stable.4 Another study found that risk of dying from cardiovascular disease was higher in people who lost weight. That risk increased with more weight lost and the group that lost over 22 pounds was at 3.5 times higher risk of dying from cardiovascular disease compared to the weight stable group.5

They cite a couple of research papers:
