Olympic breakfasts: Kelly Parker, footballer

If we have an early game in the afternoon, breakfast is high in carbohydrates. It would be granola, different cereals, muesli or oatmeal with yoghurt or milk. And some fruit too – kiwi, pineapple, banana. Football is an endurance sport so we have to make sure we get enough fuel to our muscles. We leave protein out because it puts your body under more stress to digest. Nearer the game you want simple sugars in your body. If you don't eat right you get cramps – you feel it more in your legs in the second half and you burn out earlier.
