A calorie-restricted diet may slow aging in healthy adults, research finds (NBC News)

NBC News, U.S. News & World Report,  and Yahoo News featured Valter Longo on how caloric restriction could affect health and aging. Longo said long-term restriction should be approached with caution: “It may cause powerful anti-aging effects, but also probably some degree of frailty or other issues that may not be so beneficial,” Longo said.
