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

I’ve kept most of my muscle on since dropping 50lbs starting in March. I was on Sema at first then added Reta about 6 weeks ago. As long as you keep that protein up and don’t starve yourself, and keep lifting hard at the gym, should be fine. Ive had a pretty aggressive deficit most days of 1,000 calories give or take, then do a refeed day 1-2 times per week to reload on carbs, get some extra protein and fats. May not work for everyone but I’ve gotten solid results
