“Can being hungry also prolong life?

　　Scientists discovered more than 70 years ago that if animals such as mice, dogs, and fruit flies are kept in a certain degree of hunger, their survival time is 40% longer than that of their counterparts who eat normally. Researchers at the Salk Institute for Biological Studies in California, USA, recently discovered the PHA-4 gene in experiments.

　　American scientists have discovered a gene that can extend the life of some animal organisms. This gene, called PHA-4, reveals the secret that controlling food intake can extend the life of animals. However, since human genes are far more complex than those of ordinary animals, this discovery does not mean that a "magic pill" for immortality can be produced, but it will help researchers study human body functions and find ways to extend human life.

　　Expert Dilin pointed out that from animal experiments, reducing normal food intake by 50% to 70% can achieve the effect of extending life. In fact, controlling eating is not a simple matter. "Reducing food too much will lead to hunger and shorten life." But eating too much will "lead to excessive obesity and shorten life."

　　Now, after seeing the evidence provided by authoritative scientists, it seems a bit difficult not to believe it.
