Carno-moderate. For that matter, carbo-moderate, veggi-moderate, rough-o-moderate--heck, just plain moderate. I trust my body to tell me when I'm getting low on any of the above (vitamins are a different matter). Therefore, I'm biased against most formulaic diets.

However, breakfast will always have a warm place in my heart (and gut). Common breakfast for me:

Cut a medium peeled potato into 1/2 inch cubes.
Fry in a wok.
Add some onion.
Add 2-3 eggs (depending on size).
Serve with ketchup and sausage.

Mmm, good. But general rule is: anything they serve at IHOP is fine by me (but better at home). On the other hand, some of the worst meals of my life were breakfasts on the Shepperton lot--all the things Peter rattled off? I's agin' 'em.
