I’m on mounjaro, and do my best to ingest 150g of protein per day, plus lifting 3x a week. Prior to the increase in protein (as a percentage of my diet) I’d lost about 5# worth of muscle, as measured by an in body 270, and about 20# of fat. Since I’ve upped my protein intake I’ve started gaining the muscle back while continuing to lose fat.
Can’t do this stuff without tracking your body comp or you’re going to end up in a world of hurt.
