I've been low carb for years but for the last 3 months I've been following a more strict, paleo style whole foods diet. A typical day for me is this:
Almond milk x 2 coffees
Breakfast: 100g chicken, 28g walnuts, salad leaves and homemade mayo. (May exchange eg. Chicken for mackerel or boiled eggs, and the nuts for avocado)
Lunch: frozen portion of leftover meal (homemade) with salad or similar to breakfast; protein, fat, veg
Dinner: homemade casserole, curry, meatballs, loads of veg. Or fish/steak/chicken breast and salad or winter veg. Maybe a piece of fruit.
No snacks.
Several pints of water
Herbal tea
I don't count calories as such but a lifetime of doing so means I can sort of accurately guess a portion size and I do occasionally tot up the cals as force of habit really. I guesstimate that to be about 1800 cals, 600 cals for each meal, with the vast majority of my cals coming from protein and fat. I only really eat heavy carbs (eg banana or sweet potato) if I am doing a long run the next day or if I am really tired and just need some carb- loading.
I run 5-7km average a day, do circuits 2-3 times a week, and yoga. I cook everything from scratch; no dairy, grains, sugar (except the sugar in occasional fruit and tonnes of veg), legumes or soy.
I can honestly say my diet is the healthiest it has ever been and, after 3 months of no junk whatsoever, not even a crumb of toast or grain of sugar, I feel a million dollars. However, it is drastic and not for everyone to do this and I think it is as much a weakness as it is a strength to be able to control food to this extent.
