TED-Ed: How does your body know you're full? - Hilary Coller

The video explores the physiological processes of hunger and fullness. It begins by describing the sensation of hunger and how fullness is achieved as food moves through the digestive system. The role of the vagus nerve and hypothalamus in signaling fullness is explained, along with the influence of hormones like cholecystokinin, insulin, and leptin. The video also highlights how different foods affect satiety and how hunger returns as hormones like ghrelin are produced. Overall, it provides a comprehensive overview of the body's mechanisms for regulating appetite.

What triggers the sensation of fullness as food enters the stomach?

• The release of insulin

• The stretching of the stomach walls

• The production of ghrelin

• The presence of leptin

Which hormone is responsible for reducing the reward feeling associated with eating?

• Leptin

• Insulin

• Ghrelin

• Cholecystokinin

How does eating slowly affect the sensation of fullness?

• It decreases the production of ghrelin

• It allows the stomach to stretch more over time

• It increases the release of insulin

• It speeds up the movement of food to the intestines

What role does leptin play in the regulation of hunger?

• It stimulates hunger-causing neurons

• It inhibits neurons that drive food intake

• It decreases the release of insulin

• It increases the production of ghrelin

Which type of food is considered to be more hunger-satisfying?

• Sugary snacks

• Boiled potatoes

• Croissants

• Fried foods
