Snorting Insulin May Decrease Food Intake in Men and Improve Memory in Women

This is a report of an odd but interesting study that will be published in the Journal of Clinical Endocrinology & Metabolism.

Research by the University of Lubeck in Germany found that intranasal (through the nose) insulin decreases food intake in men but not women. However, in women the intranasal insulin improves memory function, but does not have the same effect in men.

Previous studies have shown that insulin plays a key role in the regulation of central nervous functions such as metabolism and memory. For this study, 14 men and 18 women were administered regular human insulin intranasally before performing a series of cognitive tests.

This study suggests that insulin may be helpful in the treatment of Alzheimer’s disease in women and obesity in men.
