A recent study published in the journal Cell Metabolism found lowering calorie intake by just 15 percent—or 300 calories from the recommended daily guideline of 2,000—can slow aging and metabolism, leading to an overall healthier life and more positive mood.
The trial, called CALERIE (Comprehensive Assessment of the Long-Term Effect of Reducing Intake of Energy), examined people at a healthy weight and how restricting calories could affect their metabolism.
For two years, 53 men and women between the ages of 21 and 50 cut calories by 15 percent without following any particular diet. Calories were calculated specifically per individual with the goal to maintain weight. Though the study’s main purpose wasn’t weight loss, participants lost around 20 pounds on average.
