New research suggests time-restricted eating under 8 hours may elevate cardiovascular mortality risk.

Observational analysis of over 20,000 US adults shows a significant risk increase for those with an 8-hour eating window.

Participants with cardiovascular disease eating 8-10 hours daily faced a 66% higher risk of fatal heart disease or stroke.

The study prompts reevaluation of intermittent fasting health risks and consideration of individual well-being before trend adoption.

Researchers emphasize the importance of heart-healthy diets, such as Mediterranean and DASH-Style, over restrictive eating patterns.
