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

Saxenda® is an analog of human GLP-1, a physiological regulator of appetite and food intake5*

† Data from a 5-week pharmacodynamic trial of 49 obese (BMI 30–40 kg/m2) non-diabetic patients. Appetite sensations were assessed before and up to five hours after a standardized breakfast meal, and ad libitum food intake during the subsequent lunch meal.

GLP-1 = glucagon-like peptide-1.
