May not only increase life span, but reduce the risk of a host of degenerative diseases. (This means aiming for a 1200 calorie intake per day instead of 2000.)
Cutting caloric intake to 60% of normal

From Scientific American:
[..] researchers at the Salk Institute for Biological Studies have cracked open the black box of how persistent hunger promotes long life and identified a critical gene that specifically links calorie restriction (CR) to longevity.
"After 72 years of not knowing how calorie restriction works, we finally have genetic evidence to unravel the underlying molecular program required for increased longevity in response to calorie restriction," says Andrew Dillin, Ph.D., an associate professor in the Molecular and Cell Biology Laboratory, who led the study published online in the May 2 issue of Nature.
Having identified a key link between calorie restriction and aging also opens the door to development of drugs that mimic the effects of calorie restriction and might allow people to reap health benefits without adhering to an austere regimen that only ascetics can endure.
The potential payoff for cutting to 60 percent of normal while maintaining a healthy diet rich in vitamins, minerals, and other nutrients, is huge. Currently it is the only strategy apart from direct genetic manipulation that consistently prolongs life and reduces the risk of cancer, diabetes, and cardiovascular disease, while staving off age-related neurodegeneration in laboratory animals from mice to monkeys.
