Can eating less help you live longer?
The idea dates back to the 16th century when Venetian nobleman Luigi Cornaro transformed his health with a strict, calorie-restricted diet—living to 100-ish (his actual birthdate is debated) and writing a bestselling guide about it.
Fast forward 400 years, and scientist Clive McCay took the concept to the lab, proving its benefits in rats.
The first large-scale human trials in 2015 confirmed it: moderate calorie restriction improves health, restores organ function, and even helps eliminate senescent cells. Could this centuries-old practice be the key to longevity?
