There’s more evidence that you can you live longer and age more gracefully by drastically reducing the amount of food you eat.
A long-anticipated study in the journal Science found that monkeys who eat less have a longer lifespan and better quality of life in old age.
Although the study was conducted on primates, scientists say the findings likely apply to people, too, and could have profound implications for human health.
The study showed that by cutting the calorie intake of monkeys by 30 per cent over a 20-year period, they were less likely to die from heart disease, cancer and diabetes, and less likely to have brain atrophy, than monkeys who ate whatever they wanted.
Researchers say the restricted diet serves to reprogram metabolism in a way that slows aging.
Scientists have already confirmed the relationship between diet and aging in other life forms, including yeast, worms, flies and rodents. They have also studied small groups of humans who follow calorie-restricted diets and found they have better-functioning hearts.
Most caloric restriction studies have found that a lifetime of deprivation is needed to achieve the longer-life benefits, and many research teams are working on ways to replicate the findings with drugs.
