Running moderate deficit is key specially as a newbie.
Most people do not get fat because they are eating 1000s of calories in surplus each day; in fact, most people get fat over a long period of time and they might be eating only 100-200kcal more than what they need to maintain their weight or perhaps after getting fat they are eating at maintenance.
If you remove 300 kcal from your diet, you'll perhaps not even notice this, yet you'll end up losing 14 kg or 30 lbs in a year without much effort.
Very few people actually need GLPs for "appetite suppression."
If you want to run 1000 kcal deficits, GLPs make it very easy for people to crash their intake.
Crashing intake may result in bile/gallbladder issue or hairloss
Even GLP users recommend the macrocodex:
