Emilia Clarke has been banned from eating "anything that tastes good".
The 26-year-old actress is currently undergoing a gruelling regime of preparation ahead of appearing as Sarah Connor in 'Terminator: Genesis', and her strict diet includes a ban on wheat, sugar, caffeine or dairy.
She said: "I have not been allowed to eat anything that might taste at all good. But don't think I'm complaining because, believe me, I know exactly how lucky I am."
Eyeing a high tea spread of sandwiches, scones, cookies, sweets, cream and teas, she added: "Everything on these plates look amazing but, heartbreakingly, I'm not allowed to eat any of it. Not one thing on this table. Except a cup of tea. One cup of tea. No sugar. No cream."
As well as her diet, the 'Game of Thrones'' star has been "kicking a lot of ass" in fight training for her new role.
She told Britain's InStyle magazine: "I've been spending all day, every day in weapons training. I've been shooting guns, weightlifting, kick boxing and generally kicking a lot of ass."
