They eat nothing but boiled eggs

During the filming of Cold Mountain, there were rumours that one famous actress on set ate only boiled eggs.

She would rise in the morning and eat one and then have one or two at the end of the day. That was her entire diet.

And apparently she is not alone.

Celebrity trainer David Kirsch says: "I had a client who was getting ready for the Oscars and all she ate was one meal a day - of two boiled eggs! I was able to persuade her to add some almonds and a protein shake and some vitamin supplements.

"It's a self-defeating strategy, you need to eat enough, and particularly protein, to build lean and toned muscle in the first place."
