Okay BUT, if you are very active, then the sugar gets fed to your muscles or at least that happens soon enough, instead of your liver having to compensate.
I was plenty healthy as an active youth while eating and drinking just about anything. Sitting around coding per the suggested example, not so much.
In other words, health is a sum of all decisions made. If you keep active, you avoid a lot of the pitfalls that sedentary people face. I suppose that's a double edged sword in that more healthy people are more able to stay active, kind of like a black hole's gravity where you want to keep your critical escape velocity high enough to not get sucked in.
On the opposite end of the spectrum, let yourself get too ill and you end up with digestive and or sleep problems and it's all downhill from there. Eat/sleep/exercise, all an important part of the health triangle.
