Michelle Pfeiffer has revealed that she unknowingly became involved in a bizarre diet-based cult back in the early 80's. 

Speaking with The Sunday Telegraph’s Stella magazine, the 55-year-old actress says she fell in with a "very controlling" couple after moving to Hollywood. The duo, described as "personal trainers" believed in breatharianism - the ability to survive without food or water. Instead, followers channel nourishment from the air and sun or "prana". According to one regimen I saw online, the pathway to prana is to slowly transition your body from vegetarian to vegan to raw foods, fruits, liquids, and then finally prana. 

"You replace physical food with air and light as well as metaphysical nourishment," writes the author. 

Naturally, nutritional science warns against these extreme diets and fasts - with documented cases of deaths from attempts at breatharian fasts

Pfeiffer, herself a vegan for several years now, said the restrictive diet prescribed to her was something "nobody can adhere to."

The actress says she was finally able to see the group for what they were after doing research on cults for a movie and coming to the startling realization that she was in one. 

“They were very controlling," she says. "I wasn’t living with them but I was there a lot and they were always telling me I needed to come more. I had to pay for all the time I was there, so it was financially very draining.”
