What physiological effect does GIP have on food intake regulation in comparison to leptin?
Understand the Problem
The question is asking us to compare the physiological effects of GIP and leptin on food intake regulation, specifically how they affect appetite. We need to analyze how each hormone influences appetite and make a comparison based on the options provided.
Answer
GIP reduces leptin's action, contributing to leptin resistance, while leptin suppresses appetite.
GIP diminishes the action of leptin in the brain and is linked to leptin resistance, while also being involved in decreasing energy intake and increasing energy expenditure. Leptin, in contrast, primarily acts to suppress appetite and regulate energy balance.
Answer for screen readers
GIP diminishes the action of leptin in the brain and is linked to leptin resistance, while also being involved in decreasing energy intake and increasing energy expenditure. Leptin, in contrast, primarily acts to suppress appetite and regulate energy balance.
More Information
GIP plays a complex role in food intake regulation by interacting with several neural pathways, while leptin is a key hormone in appetite suppression and energy balance. Leptin resistance is a significant factor in obesity.
Tips
A common mistake is to assume both GIP and leptin act independently without interaction, but GIP's effect on leptin resistance shows their actions are interconnected.
