Researchers Reveal the Surprisingly Easy Habit Linked to Longer Healthier Lives

A Tufts-led analysis of the CALERIE study found that cutting calories by about 10% to 15% improved markers linked to heart and metabolic health.

Participants showed better blood pressure, LDL cholesterol, and insulin measures, along with other signs of healthier aging.

The findings suggest moderate calorie restriction may be a realistic, low-cost way to reduce age-related disease risk and support healthspan without extreme dieting.
