I run 3-4 times a week, and do Scottish dancing 2-3 times. I try to keep my carbs around 100-150 per day, protien up near 100, and if I'm being very good I also 5:2 (2 days at 500 cals. But I cheat a lot).
Breakfasts: I vary between eggs (1 whole, 1 white scrambled in the micro with mushrooms, spinach, ham, any leftover meat or veg, sometimes a little cheese). I don't eat bread every day, but I keep a loaf of Burgen in the freezer, nad have one slice toasted with either marmite and cottage cheese, or peanut butter and a smear of ginger jam. greek yoghurt with berries and flaxseed. Porridge in the winter, overnight oats/ Bircher muesli in the summer. On a long run day, it'll be oats for brekkie.
Lunches: soup or stew based. I do a fridge clear out at weekends, and make a big vat of whatever needs using, possibly adding a tin of tamoatoes and/or beans. freeze in individual portions. Or salad - spinach, artichoke hearts, olives, radishes.
Dinners - fish, steak or chicken with veg. Pasta if I've been running. I'm not a dessert person, though DH is partial to a cheesy cracker in the evening, and I will join him.
Lots and lots of water.
