Why don't you quit reading Hacker News? There's no need for it. In fact, there's no need for using the Internet at all. Hell, why are you even on a computer? All you really need is a warm fur coat and a hatchet. What are you, some kind of hedonist?

That only works if your extra calories come from glucose intake. It wouldn't help for complex carbs, fat, or protein.

Not true AFAIRC. Lipids are absorbed as lipids (fatty acids), proteins as amino acids. Aminos can be broken down into sugar, though.
