11. Janet Jackson
The famous sister of Michael Jackson has been known to have problems with her weight throughout her entire career. She would appear in good shape at some points, but then appear a bit heavier in others.
To get into shape for her Love Will Never Do music video, she says that she ate only a small bag of chips and one apple every day until she attained the figure she desired. This is not a recommended diet plan that people should follow and Janet was well aware of that. To maintain her beautiful figure today, she works out regularly with a personal trainer and also sticks to a pescatarian diet.
