When weight falls quickly, those compartments lose volume faster than the overlying skin can fully retract
While it might seem counterintuitive to activate a receptor associated with raising blood sugar, glucagon receptor activation increases energy expenditure through thermogenesis and promotes lipid mobilization
In a randomized, single-blind, 24-week study, participants assigned to dual therapy of 2 mg weekly of the GLP-1 receptor agonist exenatide (Bydureon, AstraZeneca) and 10 mg daily of the SGLT2 inhibitor dapagliflozin (Farxiga, AstraZeneca) lost more weight than those taking either agent alone or those receiving dapagliflozin and metformin extended-release (Xigduo XL, AstraZeneca) or phentermine/topiramate extended-release (Qsymia, Vivus)
The average weight loss on retatrutide depends on the dose and trial
However, the GLP-1R is also involved in adipogenesis in the periphery, which may account for this discrepancy (Challa et al., Glp1r/ mice, animals with deletion of the GLP-1R in vagal afferent/efferent nerves, Phox2b-Cre Glp1r flox/flox , as well as animals with a deletion of the GLP-1R in the CNS, nestin- Cre Glp1r flox/flox , maintain a similar body weight and food intake as control mice on both chow and HFD (Sisley et al., 2014)
