Night Owls Face Significantly Higher Risk of Type 2 Diabetes

New research links late bedtimes to higher BMI, larger waists, and increased visceral and liver fat.

Study followed over 5,000 participants for nearly seven years, finding a 46% higher risk of diabetes among night owls.
Increased risk persists even after accounting for unhealthy lifestyle factors such as poor diet and lack of exercise.
Higher body mass index and larger waist circumference observed in late chronotypes contribute to greater diabetes risk.
Night owls also have significantly more visceral fat and liver fat, which are linked to metabolic disturbances.
Researchers suggest adjusting meal times and sleep schedules to potentially mitigate diabetes risk.
