The front-loaded pace in months 1-4 versus the slower back half is the standard pattern rather than an exception. The early loss is partly water weight and higher caloric deficit from novel appetite suppression; the body adapts over time which is why the 20 lbs after the initial phase takes longer. The energy replenishment point is worth tracking - extremely restrictive intake combined with GLP-1's satiety effect can mean people aren't eating nearly enough to maintain muscle or energy stores. At 200 lbs and 11 months, the question worth asking is whether protein is still hitting a real number and whether the current intake is sustainable at that level. The slower pace from here isn't a failure of the medication; it's the body settling into a new equilibrium.
