Given you're at a computer using HN, then at any 
    off time a good meal is no meal

I don't quite follow, are you saying because one sits behind a computer one doesn't use any energy at all?

    You can safely say stuffing more food into you 
    is not needed.

Food gives energy and mental exhaustion, believe it or not, does actually take up a lot of energy, heck, even just resting takes up energy (it's not like your body stops functioning..).

I have to say that I very much follow what the parent is saying. I love eating with people and all, but, I'm not always with someone, and more often than not am too lazy to cook (or I've just forgotten to shop groceries).
