The proposed mechanisms for tirzepatide's efficacy include: Augmented insulin secretion : GIP receptor activation may complement GLP-1-mediated insulin release, particularly in the postprandial state Potential effects on insulin sensitivity : Emerging evidence suggests GIP signalling in adipose tissue might influence lipid metabolism Weight reduction : Dual agonism appears to produce pronounced effects on appetite suppression Effects on lipid parameters : Early data suggest GIP receptor activation may influence lipid metabolism alongside GLP-1 effects Both tirzepatide and exendin-4-based agents exhibit glucose-dependent mechanisms , meaning insulin secretion is enhanced only when blood glucose levels are elevated

It can repeat the cycle (waning and waxing pattern) for a couple of days, weeks, or months
Understanding how these medications interact with cortisol and stress hormones helps explain why many patients report improved mood and reduced anxiety alongside weight loss
