Eating a high-fat diet containing a large amount of oleic acid—a type of fatty acid commonly found in olive oil—could drive obesity more than other types of dietary fats, according to a study published in the journal Cell Reports.

The study found that oleic acid, a monounsaturated fat associated with obesity, causes the body to make more fat cells. By boosting a signaling protein called AKT2 and reducing the activity of a regulating protein called LXR, high levels of oleic acid resulted in faster growth of the precursor cells that form new fat cells.

Disruption of the circadian clocks that keep the body and its cells entrained to the 24-hour day-night cycle plays a critical role in weight gain, according to a pair of studies by Weill Cornell Medicine investigators.

One study, published June 27, in Cell Reports revealed that stress caused by chronically administering glucocorticoid stress hormones and disturbing the normal daily cycle of release triggers a temporary protective mechanism in mice. This mechanism boosts fat cell growth and insulin production while reducing excess blood sugar and fat levels in the bloodstream and liver. The second study, published Aug...
