Zac Efron has opened up about the extreme regime required to produce his Baywatch body and warned others about the devastating effect it had on his long-term well-being.

In an interview with Mens Health , the actor said achieving the shredded look in the 2017 action comedy came at a cost to his physical and mental health. Efron played Matt Brody, an Olympic swimmer who becomes a lifeguard to rehab his image after a controversy.

That Baywatch look, I dont know if thats really attainable, he told the magazine. Theres just too little water in the skin. Like, its fake; it looks CGId. And that required Lasix, powerful diuretics, to achieve.
