GLP-1 agonists work by activating the GLP-1 receptor, which is found all around the body. Some sites are on beta cells in the pancreas and on neurons in the brain.
Liraglutide was the first GLP-1 receptor agonist that was FDA-approved for weight loss. It helped one-third of the non-diabetic study patients achieve a loss of 10% of their body weight and also helped them sustain their weight loss for upwards of 1 year [131].

Therefore, GLP-1 receptor agonists are primarily used in managing type II diabetes and, in some cases, for weight loss. Interestingly, GLP-1 receptor agonists resist degradation by the enzyme DPP-4 (dipeptidyl peptidase-4), which usually breaks down natural...
19 reported the development of a GLP-1 receptor (GLP-1R)/GCGR co-agonist, which led to weight loss in diet-induced obese mice, without a simultaneous occurrence of hyperglycaemia, supporting further studies in human trials. Similar findings were reported by Pocai et al.
