Question

question 9 what is the primary mechanism by which glp-1 agonists like liraglutide, semaglutide, and tirzepatide promote weight loss?
they decrease the absorption of nutrients in the gut.
they decrease feelings of fullness.
they increase the rate of gastric emptying.
they promote satiety and reduce hunger.

Explanation:

GLP - 1 agonists work by mimicking the action of the GLP - 1 hormone. They act on the brain's appetite - regulating centers and the gut. They do not decrease nutrient absorption (so option A is wrong), do not decrease fullness (option B is wrong as they increase fullness), and do not increase gastric emptying rate (they actually slow it down, so option C is wrong). Instead, they promote a feeling of satiety (fullness) and reduce hunger, leading to reduced food intake and weight loss.

Answer:

D. They promote satiety and reduce hunger.
