Hormonal

GLP-1 receptor agonists (specifically liraglutide 3.0 mg) produce clinically significant weight loss in overweight or obese individuals through reduced appetite and energy intake, rather than increased energy expenditure.

If you are overweight or obese, GLP-1 receptor agonists like liraglutide (3.0 mg daily) are a clinically proven tool for weight loss. They work by making you feel fuller and reducing your desire to eat, not by speeding up your metabolism. Treatment involves starting at a low dose and slowly increasing it to manage side effects. This intervention is most effective when combined with your usual lifestyle habits, though significant weight loss occurs even without strict diet changes in some studies.

GoodSupportsHIGH confidence
Thus, the evidence supports reduced appetite and food intake, without an increase in energy expenditure, as the mechanism underlying weight loss with liraglutide.
