Decrease the intake of calories not only helps to maintain weight, but also could help prevent the development of pathologies associated with age and have a longer life, according to the findings of several studies in this regard.
In the University of California, in the United States, they have carried out an investigation with the fruit fly in which they have verified that this insect increases its physical activity and suffers an increase in the metabolism of fat in the muscle - and consequently It prolongs his life - when he reduces the intake of yeast, which is the main source of protein he gets from his diet.
The results of the research suggest that to increase life expectancy it is necessary to combine two factors: dietary restriction and the practice of physical exercise
When the researchers removed the yeast from the fly diet they observed how the insects became more active, and verified that this was due to an alteration of their metabolism that resulted in an increase in both the synthesis of fat and its decomposition . The greater physical activity had a positive repercussion, since it prolonged the useful life of the flies.
Pankaj Kapahi, from the Buck Institute for Research on Aging from the University of California and lead author of the study, explains that the results of the research suggest that in humans it would not be positive to restrict the intake of nutrients if this is not accompanied by an increase in physical activity and that, therefore, , to increase life expectancy it is necessary to combine both factors: dietary restriction and the practice of physical exercise. In addition, he points out that precisely making the right changes in the diet can make people more motivated to play sports.
