Instead of intermittent fasting, a less stringent and safer diet can be used to slow aging; This diet involves short-term restriction of the amino acid isoleucine. This has been shown by a published study on flies. geroscience.
Previous studies in cells and animals have shown that intermittent fasting can slow aging and reduce the risk of obesity and diabetes. This approach involves limiting food intake to a few hours per day; This carries its own health risks and can be difficult for many people.
In a new study on fruit flies (Drosophila melanogaster) scientists have found that a diet containing limited amounts of the amino acid isoleucine can achieve the same results as intermittent fasting.
The experiment showed that cyclic restriction of isoleucine led to a noticeable (5%) increase in life expectancy in aged flies. Moreover, the result did not depend on the nutrition of the young insects.
In previous studies, the study authors found that short-term restriction of isoleucine increased the resistance of young flies to the toxin (nicotine). A similar effect was observed in old flies. The approach suggested by scientists could become a more targeted and safer alternative to intermittent fasting.
