Michelle Pfeiffer has confessed that she was encouraged to live on a diet that nobody can adhere to.
The then 20-year-old actress found herself practicing 'breatharianism' - existing without food and water, as believers trust that sunlight can provide all the nourishment the body needs, the Daily Express reported.
According to The Sunday Telegraph's Stella magazine, the now 50-year-old actress said that she was saved by her first husband, Peter Horton, who had been cast in a film about the Moonies, the name given to followers of Rev Moon Sun-myung's Unification Church.
As she helped in the research, it "clicked" that she too was part of a cult.
She also added that the couple who had encouraged her were kind of personal trainers, who asked her to visit frequently, but it became financially very draining as she was made to pay for each trip.
