Obese subjects do not exhibit the decline in plasma ghrelin and leptin seen after a meal in the lean. The role of the decline in leptin is unclear but given the orexigenic properties of ghrelin, the lack of suppression following a meal in obese subjects could lead to increased food consumption and suggest that ghrelin may be involved in the pathophysiology of obesity.
