on a glp-1, muscle is the thing you have to defend
— Priya Sharma · HappierFit Field Notes · supplements and the evidence behind them
The scale is moving in the right direction, and some of what's leaving is muscle you'll badly want back.
This is the part of GLP-1 weight loss that gets undersold. In the S-LITE trial (New England Journal of Medicine, 2021), adults who kept weight off on the GLP-1 drug liraglutide alone gave up more lean mass than those who paired the same drug with a structured exercise program. Only the combination held onto muscle while also improving fitness and insulin sensitivity. The read on that is plain: the medication is very good at removing fat and completely indifferent to whether the tissue walking out the door is fat or muscle. Which tissue leaves gets decided by what you build around the drug, not by the drug.
Muscle isn't a vanity line here. It's where you store glucose, it's most of your resting metabolism, and it's the difference between weight you keep off and weight that returns the moment the prescription pauses.
The move, if you're on a GLP-1 or about to start: treat resistance training two or three times a week as part of the protocol rather than a nice extra, and put protein into every meal instead of backloading it all at dinner when your appetite has already flattened. Lighter appetite is the whole point of the drug, which means the protein has to be deliberate, because it won't arrive on its own through hunger. You don't need a perfect program. You need the muscle to have a reason to stay.
