Weill Cornell Medicine study links stress hormone rhythms to obesity
Researchers at Weill Cornell Medicine have found that the timing of stress hormone fluctuations may play a significant role in weight gain, independent of caloric intake.
In a study involving mice, scientists disrupted the natural daily rhythm of stress hormones using corticosterone-releasing implants. While the average hormone levels remained largely within normal ranges, the timing of the peaks and troughs was altered. Despite consuming a standard diet, the mice with disrupted rhythms gained nearly as much fat over a 30-day period as mice fed a high-fat diet.
The findings suggest that the circadian rhythm of hormones like cortisol is a critical factor in metabolism, potentially explaining how lifestyle factors such as shift work, which can disrupt these rhythms, might contribute to obesity.
