Researchers Reveal the Surprisingly Easy Habit Linked to Longer Healthier Lives

Key Points:

• A long-term study from Tufts University, known as CALERIE™, found that reducing calorie intake by 10% to 15% can significantly improve heart health, lower blood pressure, and enhance glucose control, thereby reducing age-related disease risk.
• In the study's initial phase, participants who moderately restricted calories by about 12% experienced notable declines in blood pressure, LDL cholesterol, insulin levels, and lost around 10% of their body weight, despite the original goal being a 25% reduction.
• The calorie restriction did not compromise nutritional quality, and participants produced fewer reactive oxygen species—unstable molecules linked to cellular damage and diseases—suggesting improved cellular health.
• Researchers are continuing to analyze long-term effects, with follow-up studies examining whether participants maintained lower calorie intake and sustained health benefits more than a decade later.
• Experts recommend moderate calorie reduction as a feasible and effective strategy for healthy aging, cautioning certain groups to consult doctors before making changes, and suggesting simple lifestyle adjustments like skipping high-calorie treats or adopting intermittent fasting.
