I did a research for another thread, and I found this slightly relevant info:
"This finding may explain recent studies suggesting that eating less may, in fact, raise ROS (reactive oxygen species) levels – and, in doing so, provide protection from acute doses of oxidants. This is counter to the hypothesis that caloric restriction extends lifespan in some species because it reduces ROS produced as a by-product of the energy regenerated by mitochondria.
"It may be that adaption to oxidative stress is the main factor responsible for the lifespan-expanding effects of caloric restriction," "
I will try to explain what it means. Earlier they thought that calorie restriction expands life because it reduces ROS. It turned out that it actually increases ROS, but that is not a bad thing, because in small doses it helps the body to adapt to it, so when the big ROS shows up, the body suffers less damage.
Sorry for the interruption, please continue...
