GLP-1 receptor agonists are medications (such as semaglutide, tirzepatide, and liraglutide) that mimic a natural gut hormone, helping lower blood sugar, reduce appetite, promote weight loss, and decrease inflammation. Can GLP-1 medications help with both diabetes and weight loss
cAMP activates PKA, which will phosphorylate the 2 subunit of the L-type VDC channel and the Kir6.2 and SUR1 subunits of the K ATP channel, increasing K ATP channel sensitivity to ATP and leading to K ATP channel closure, cell membrane depolarization and VDC channel opening, followed by Ca 2+ influx through VDC channels into cells to promote the exocytosis of insulin granules and the acute secretion of insulin and into circulation (Bnemann et al., 1999

For context, semaglutide clinical trials showed approximately 15-17% body weight loss on average, and tirzepatide achieved 20-22% in some studies
