According to a contrary hypothesis, oxidative stress from reactive oxygen species (ROS) is thought to positively stimulate cell metabolism (Hormesis), which may explain the health benefits of caloric restriction as well as Fasting, oxidative plant compounds in cabbage vegetables, and physical training. | According to a contrary hypothesis, oxidative stress from reactive oxygen species (ROS) is thought to positively stimulate cell metabolism (Hormesis), which may explain the health benefits of caloric restriction as well as Fasting, oxidative plant compounds in cabbage vegetables, and physical training.{{pmid|16242247}} | ||
In contrast to the free radical theory, it is assumed that an increased formation of reactive oxygen species in the mitochondria, associated with caloric restriction, causes an adaptive response that enhances stress resistance. | In contrast to the free radical theory, it is assumed that an increased formation of reactive oxygen species in the mitochondria, associated with caloric restriction, causes an adaptive response that enhances stress resistance.{{pmid|20350594}} | ||
