Caloric restriction
Jul. 7th, 2008 07:50 pmI'm on day 2 of food poisoning. Food poisoning has dramatically reduced my hunger level, so I don't feel a strong desire to eat even though I've eaten very little over the last few days.
There's a thing called "caloric restriction" that involves cutting your calorie intake 20-40% in order to live longer. It apparently works very well on mice, dramatically lengthening their lifetimes. So of course people wanting to live longer try it. Whether it works on people or not is still up in the air.
No one asked the mice how they felt about the diet though. Life is about quality, not just quantity.
Ordinarily I'd never try caloric restriction, even for a few days, because the sensation of being perpetually hungry is too distracting to me.
However, since the food poisoning is suppressing my desire to eat, I can directly experience what it's like to live under calorie restriction. Conclusion? It's not so good.
With so few calories coming in, my body seems to be reducing its energy expenditures. The brain uses a lot of energy. As a result, my body might not be willing to "spend" as much energy running my brain. This might explain why I feel like my thoughts have been slow and sloppy.
It's not the way I'd want to live my life, even a dramatically extended one.
I also had the thought today that this is what my average day will be like when I'm 80. I'm hoping for some big breakthroughs in medicine in the next few decades.
