Stress hormone timing creates a different kind of obesity, study suggests

Obesity caused by disrupted stress-hormone rhythms is metabolically very different from obesity caused by a high-fat diet, according to a new preclinical study by Weill Cornell Medicine investigators. The researchers found in mice that glucocorticoid-rhythm disruption concentrates insulin resistance in skeletal muscle while preserving key insulin responses in fat tissue and liver. This allows fat tissue to continue storing lipids, while the liver remains largely protected from the fat accumulation typically seen with high-fat-diet obesity.
