| Apart from its role in regulation of fat metabolism, leptin may also regulate insulin release as part of an adipoinsular feedback. |
| Injections of leptin have been used to help morbidly obese people with a deficiency of the hormone to lose weight. |
| Neck, waist, and hip girth, skinfold thickness, and fasting serum levels of lipids, glucose, insulin, and leptin were compared between these two groups. |
| The absorbance measured is directly proportional to the concentration of human leptin present. |
| Our bodies are thought to have a built-in system to measure levels of a key protein, leptin, which is produced in fatty tissue. |
| Sleep deprivation lowers leptin, a blood protein that suppresses appetite and seems to affect how the brain senses when the body has had enough food. |
