The injectable GLP-1 RAs liraglutide 3 mg once daily and semaglutide 2.4 mg once weekly have both gained a licence for weight loss, alongside lifestyle management, in obese/overweight people without T2D (SmPC, 2023b
& Storey, K
A 300-pound person loses a higher absolute amount of weight (24% of 300 pounds = 72 pounds) than a 200-pound person (24% of 200 pounds = 48 pounds) on the same dose, because there is simply more metabolically active tissue responding to the signal
Supporting Evidence A few studies focus on ipamorelins influence on GH

Key findings from published and presented studies include: In a phase 2 obesity trial, higherdose retatrutide produced average weight loss of around 22.824.2% over 48 weeks in people with obesity. In participants with type 2 diabetes, retatrutide achieved substantial weight loss and marked improvements in blood sugar and cardiometabolic markers, though average percentage weight loss was somewhat lower than in nondiabetic obesity cohorts. Early studies also reported significant reductions in liver fat and visceral adipose tissue, with a high proportion of participants with fatty liver disease showing resolution of hepatic steatosis at higher doses. These results have led several reviews to describe retatrutide as a potential game changer in obesity pharmacotherapy, representing the first GLP1/GIP/glucagon triple agonist with robust human data. Popular coverage has highlighted phase 3 data suggesting average weight losses approaching 29% of body weight in some cohorts (roughly 71 pounds), which is about double typical results with semaglutide over comparable periods
