9. Corset

If you thought we would only include diets on this list, you were wrong. As it happens, one celeb claims she lost weight not with extreme dieting or supplements, but with the help of an ancient device – the corset.

As we know, Jessica Alba had two children. But in order to get her pre-baby body back after her second pregnancy, she resorted to using a corset with the goal of slimming down her physique.

During one interview in 2011, the actress said: “I wore a double corset day and night for three months. It was brutal; it’s not for everyone.”
