1) I can't work and starve at the same time.

2) State of evidence in favor of CR wasn't very good last time I checked. I recall something along the lines of, "Cutting calories by 40% extends the lifespan of (some short-lived creature) by a week, and it's looking like it may extend human lifespan by a week as well."

That assumes you're starving during intermittent fasting. Many practitioners actually find that they are much more clear-headed when they have not eaten recently.

My guess is that you're equating hypoglycemia with hunger. I eat a paleo diet, which has low levels of dietary carbohydrates. This forces the body to use gluconeogenesis to meet its glucose needs. Because you're producing it endogenously, your blood sugar remains completely steady. You only suffer from hypoglycemia when you're dependent upon exogenous sources of glucose, forcing you to eat every few hours. I much prefer the freedom to eat whenever I want.

I find that I'm more light-headed when I haven't eaten enough, but it's not the same as clear-headed.

I just wanted to add myself as another data point: I have been low-carb for three months and I can vouch for this. (I also lost 10 kg)

If only I had known this when I was a kid. So many mid-mornings at school, hungry (and suddenly sleepy) because of "healthy" breakast cereals!

There's prior discussion on this subject that you haven't read -- in particular, this.

There's even been a little discussion of hypoglycemia.
