The Telegraph, however, recently published Paula's 'Day on a Plate' listing what out what she eats by the hour:
"7.45am Fresh lemon juice and coffee (decaf because I'm pregnant), and a bowl of porridge with water instead of milk as I'm a bit lactose-intolerant.
8.30am Drop off my daughter at school then do my first run. Normally, I do 10 to 23 miles, but while I'm pregnant I stick to eight miles. I trained all through my first pregnancy, and was running the day before I gave birth!
10.30am A big brunch – cereals with soya milk and fruit – then weights in the gym.
12pm Half an avocado and a tin of salmon. Sleep for a few hours.
5.30pm Toast with Marmite or honey and a banana. More running, but a shorter route.
7pm Nibble on almonds while I stretch.
7.30pm I try to eat within half an hour of training. My husband makes pasta with vegetables. Fruit and soya yogurt afterwards. I love to eat adventurously, but before a marathon it's simple brown rice or grilled chicken."
While I'm no dietician, I wonder how ethical it is to publish the diet of an elite athlete in a mainstream newspaper considering lots of women might take this as 'advice'.
What do you think of Paula's diet?
