But my point is that this is no different from being skinny and frail in the first place. It has nothing to do with losing weight.
Yes, that puts you at risk. That's why you should exercise, even if it just means daily walks.
The point is, you're not winding up with too little muscle because you lost weight. If you're winding up with too little muscle, it's because you're not being physically active enough. If you're physically active, you won't lose the muscle that you still need even as you lose weight.

Imagine someone eating only candy and pastries, but because they eat so huge amounts, they actually get a half-decent amount of protein. Then they decrease portion size with the help of appetite suppresants.
If you were physically active enough and careful about your diet you likely wouldn't be on a GPL-1 drug. That's the point. People end up in bad shape for a lot of reasons, including injury. The search for a mechanism to burn fat without losing muscle is to help support people who are on GLP-1 drug because for whatever reason they were insufficiently active.
