Some of this has come up already, BUT I want to weigh in here too because it matters so much for anyone reading this (and let's assume none of us are the exception):
Weight loss fundamentally requires burning more calories than you take in.
The fifth compound and similar drugs work so well for shedding pounds because they naturally curb how much we want to eat. Everyone's nutritional needs will differ based on goals and starting point though, so I'd suggest searching for a TDEE calculator online to figure out roughly where your current versus target intake should sit.
From there, build a moderate shortfall (or surplus, depending on your goal) off your current intake and watch the pounds come off, typically expect roughly half a pound to two pounds weekly with accurate tracking (yes, a kitchen scale genuinely helps, no, deficits beyond 500 aren't worthwhile).
Extra credit if you add strength training and track macros closely, protein especially, to sidestep ending up 'skinny-fat'
I'm small-framed (5ft) and went from 135 pounds down to 105 on the second compound over the span of a year, though the real momentum only started around month three once I began tracking calories.
