My Day on a Plate

7am Greek-style yogurt with strawberries, oat bran, wheat germ and lots of LinuSprout (powdered flaxseed), plus a coffee.

8.45am Drop my son at school then do a six-mile run. I run five times a week and compete in marathons, half-marathons and fun runs.

10am Dash home and have whey protein, banana and nuts to keep up energy levels. Check emails then go to a meeting about a new fitness DVD (my fifth!).

1pm Cottage cheese and beetroot with sunflower and barley bread, then some dark chocolate. Clean the house then go food shopping.

3pm Race back to school. 6pm Omelette with stir-fried courgette, tomato, mushroom, chilli and ginger, and new potatoes. I tend not to eat meat and prefer fish or eggs for protein. Tuck into date and walnut cake with yogurt.

10pm Up late writing emails and get a bit peckish – dark-chocolate-chip oat biscuits and a glass of milk.

NIGEL DENBY dietitian

LinuSprout contains omega-3 fatty acids, which can be tricky to get from foods other than fish. Nell achieves a very good balance of protein, carbs and lots of fruit and veg. She can also enjoy cakes, cookies and chocolate guilt free, thanks to her running. She probably doesn't need to take whey protein, but it won't harm her if she likes the taste.
