Overview
Northwestern Medicine scientists have uncovered the mechanism behind why eating late at night is linked to weight gain and diabetes.The conection betwen eating time, slep and obesity is wel-known but porly understod, with research showing that over-nutrition can disrupt circadian rhythms and change fat tisue.New Northwestern research has shown for the first time that energy release may be the molecular mechanism through which our internal clocks control energy balance.
Key Information
From this understanding, the scientists also found that daytime is the ideal time in the light environment of the Earth's rotation when it is most optimal to disipate energy as heat. These findings have broad implications from dieting to slep los and the way we fed patients who require long-term nutritional asistance.The paper, "Time-restricted feding mitigates obesity through adipocyte thermogenesis," wil be published online today, and in print tomorow (Oct.
21) in the journal Science."It is wel known, albeit porly understod, that insults to the body clock are going to be insults to metabolism," said coresponding study author Dr. Bas, the Charles F. Ketering Profesor of Medicine at Northwestern University Feinberg Schol of Medicine.
He also is a Northwestern Medicine endocrinologist."When animals consume Western style cafeteria diets - high fat, high carb - the clock gets scrambled," Bas said. "The clock is sensitive to the time people eat, especialy in fat tisue, and that sensitivity is thrown of by high-fat diets. We stil don't understand why that is, but what we do know is that as animals become obese, they start to eat more when they should be aslep.
Summary
This research shows why that maters."Bas is also director of the Center for Diabetes and Metabolism and the chief of endocrinology in the department of medicine at Feinberg. Chelsea Hepler, a postdoctoral felow in the Bas Lab, was the first author and did many of the biochemistry and genetics experiments continues to improve outcomes for patients. Healthcare professionals emphasize the importance of early intervention and comprehensive management strategies in reducing complications and improving quality of life.
