The popular 5: 2 diet assumes the consumption of food for 5 days in the usual mode and then 2 extreme fasting days, during which a person is limited to the maximum in food choices.
Previously, detailed studies of such a diet have shown that it is really productive for those who want to lose weight. In addition, scientists have found that people who practice such food constantly, gradually decrease blood pressure, and therefore increase the likelihood of living a longer life.
But scientists from the University of Bath decided to test this theory on fruit flies. As the results showed, diet really has a positive effect on the body.
However, scientists have identified another, this time the negative side. Diet can lead to a 20% increase in the risk of infection by infectious diseases.
Scientists have discovered that the genes of flies, which are affected by a fungal infection, are very similar to those of people who actively follow the 5: 2 regimen.
“We know that certain stresses, such as starvation or exposure to pathogens, can indeed prolong life and increase the reproductive function of the body, but we found that, ironically, this would be a compromise in terms of immune function,” says Nick Priest, a biologist, led the study. He also adds that such results did not surprise him and the team.
The facts obtained as a result of numerous experiments on rodents, indicating that prolonged or regular starvation make them more unstable to various infections, have long been known. Nick Priest said that he would insist on continuing to study the effects of such extreme diets on the health and livelihoods of the body, since many of the relationships still remain undetected or misunderstood.
