It's interesting you bring up food. Everything goes much more smoothly when I'm fasting: I'm way more focused, and the problems that do crop up, I feel I'm able to negotiate more effectively. I tend to look at it as a kind of perverse karmic trade-off, but that's just me...

Let me just counter that with my experience. I can focus better and I get things done much better when eat regulary and when I eat well (no fast food, not too much fat etc). If I eat to late or if I only eat a sandwich for breakfast the whole day can become ruined and if I completely skip a meal I'll be worse off for a day or two.

But that's just me.

I experience this too. The period when I arrive at work before I've eaten anything is usually my most focused. I feel calm and I would describe my mind as "quiet". Once I eat, it's like everything gets noisy and I have a really difficult time concentrating for longer than about a minute on anything.
