My day on a plate: Hattie Morahan, actress 10am A hotchpotch of seeds, nuts, berries, chopped apple and soya yogurt (I'm not fussed about dairy-free - I'll eat whatever I have), and Earl Grey. 5.30pm I do a great deal of talking in the play, so warm up well. If I'm not awake enough, I have a spoonful of honey. 7.30pm Curtain up. In the interval I eat nuts and oatcakes, with water. I'm never really off stage and it's horrible to be suddenly thirsty. 10.30pm After an emotional ending I'm often drained and shaky. Nuts work for ballast but chocolate's best. G&T with friends after the show, then fall fast asleep. Hattie stars in 'A Doll's House" at the Duke of York's Theatre, London WC2 Hattie's diet is the epitome of low-glycaemic eating. Her day is packed with healthy, slow energy-releasing foods such as vegetables, nuts, oats, fruit and pulses. These regulate her blood sugars, give her stamina and prevent her from succumbing to the usual quick fixes of confectionery or fatty salty snacks. A simple diet but very well balanced - and she looks terrific on it.
