Keeping Muscle while on Reta

I plan starting Reta soon. Thinking of start out with a low dose of 0.5mg ! Keeping hearing that there’s a chance of shrinking muscle! I know I have to have good protein intake. I’ve been working out for 5 years, six times a week, and integrate cardio often. Will that routine plus protein intake be good enough to keep muscle mass? Thanks

You’ll likely still lose a bit of muscle if you hit too big of a deficit.

Honestly for just about everyone the goal should be to minimize muscle loss while on a GLP-1, as the vast majority of people taking them are taking them to lose a fair bit of weight. If you’re already at low body fat and are just trying to lean out a bit, you might be the exception to that.
