JohnR41,
I read about the studies too. I also read from another scientist, who pointed out that these monkeys were raised in a sterile environment. He says that a calorie-restricted diet can indeed be beneficial for many organs in the body, but that long-term calorie restriction can diminish the immune system. He is concerned that folks who try this in the "real world" (non-sterile environment) would not have strong enough immune systems to be able to fight off many of the viruses and chemicals and such that we all come into contact with daily.
So, while calorie restriction would help in some areas of our health, it would hurt in other areas.
If I had to make a choice (smaller meals = longer life
vs larger portions = shorter life) -- well, I like good food.
Dee101, I admire that you can follow the Hara Hachi Bu practice.
