What is the link between GLP-1 and appetite regulation?

Homeostatic responses to weight regulation include changes to behavioural and psychological systems that control energy expenditure and appetite. As part of these responses, the human body secretes several hormones that regulate appetite.1

When food is consumed, hormones such as ghrelin and leptin, and additional hormones such as GLP-1, are released into the bloodstream and may affect several areas of the brain, influencing feelings of satiety and hunger.1-5
