It's pretty clear that GLP-1 should be prescribed with protein powder. When your appetite is crushed you don't go for the chicken breast, you go for what is immediately appetizing (usually carbs+fats like pizza or fries). IMO this and a lack of resistance training (which should also be prescribed) probably makes up a large % of the muscle loss on these drugs. The problem is that the FDA only looks at dumb measures like weight lost, not body fat % when approving these drugs.
