Research overview
Liraglutide is a lab-made peptide (chain of amino acid building blocks) that closely mimics a natural gut hormone called GLP-1, which your intestines release after eating to help control blood sugar and appetite. Scientists attached a fatty acid tag to the natural hormone shape so it lasts much longer in the bloodstream. It's sold under two brand names: Victoza (for diabetes) and Saxenda (for weight loss) (StatPearls).
Mechanism under study
After you eat, your gut naturally releases GLP-1, which tells your pancreas to release insulin (which lowers blood sugar), tells your liver to stop dumping extra sugar into your blood, slows down how fast your stomach empties (so you feel full longer), and signals your brain that you're full. Liraglutide copies and extends this natural signal, which is why it both helps control blood sugar in diabetes and reduces appetite for weight loss (StatPearls).
Human evidence summary
This is one of the most well-established compounds in this whole list, with over a decade of real human data. In a major 56-week trial with over 3,700 people, those taking liraglutide lost about 8.4 kg (roughly 18.5 pounds) on average, compared to about 2.8 kg (about 6 pounds) with placebo. About 63% of people lost at least 5% of their body weight, versus only 27% with placebo (Pi-Sunyer et al. 2015). It's also approved and used for managing type 2 diabetes and for lowering heart disease risk.
Preclinical evidence summary
The source data provided doesn't detail specific animal studies for liraglutide, since it already has extensive real human trial data supporting its approval and use — animal testing would have been part of its original development process but isn't the focus of the evidence base at this point.
