Night Owls Metabolize Differently, With Higher Insulin Resistance

A new peer-reviewed study in *Obesity* found that night owls (late chronotypes) have significantly lower markers of metabolic health, including higher insulin resistance and fat mass, compared to early birds, even with similar activity levels and sleep duration. The research, led by Dr. Steven Malin at Rutgers University with 51 healthy adults, suggests your internal clock influences more than just your sleep schedule.
