Over the years we have seen many different stars in Hollywood taking on many different diets and being kind enough to share some of their diet secrets with us, so we could try to get our bodies looking as great as theirs. However, it seems that not all the diets in Hollywood are a healthy one, as some stars have had to pig out on unhealthy diets for their movies.

Daniel Radcliffe stars in What If
Enter Daniel Radcliffe, the talented British actor who will forever be remembered as Harry Potter, despite his best efforts to prove that there is more to him than that. Daniel has revealed how he had to eat a rather unhealthy diet for his new movie What If and, while he loved digging into the Fool's Gold sandwiches, his co-star Zoe Kazan was not a fan.
Radcliffe was doing a Q&A session after a screening of the movie, when he explained, "If you can get a job where people will pay you to eat Fool's Gold sandwiches, take it. Zoe hated it, but she grew up here and I grew up in England. In LA you're all very healthy here, but I am not. I am 70 per cent Fool's Gold. I enjoyed it a lot." For those of you unfamiliar with a Fool's Gold sandwich, it is a whole loaf of bread filled with a jar of jam, a jar of peanut butter, lots of bacon rashers and plenty of butter.

Zoe Kazan is also in the film
As well as starring Daniel Radcliffe and Zoe Kazan, the What If cast also includes the likes of Megan Park, Adam Driver, Mackenzie Davis, and Rafe Spall. What If is directed by Michael Dowse and will open on August 8 in the US, before then hitting the big screen in the UK on August 20.
