GLP-1 done with your muscle in mind
How we protect strength while the weight comes down, and why that decides whether it stays off.
A GLP-1 lowers appetite, and appetite is not selective. Without enough protein and enough resistance work, a quarter of what you lose can be muscle, and muscle is what keeps it off.
These medications work. That part is settled, and pretending otherwise is not useful to anyone sitting in front of me hoping for help.
What is not settled is how they get used. Mailed as a vial with a titration schedule and no other conversation, they produce weight loss that is partly muscle and rebounds the moment the prescription stops.
What these medications actually do
When you eat much less, your body takes some of what it needs from lean tissue. Studies of rapid loss without resistance training put that share somewhere around a quarter of total weight lost.
Muscle is where you burn glucose and where your resting metabolism largely lives. Losing it makes you smaller and slower at the same time, which is exactly the setup for regain.
“Appetite suppression is not selective. Your body will take the muscle unless you give it a reason not to.

What we read before prescribing
Before a GLP-1 goes on a prescription pad, we want these in front of us:
Establishes whether insulin resistance is the driver and gives us a baseline to move.
A slow thyroid will blunt results and needs correcting alongside rather than after.
Kidney and liver function decide dose safety and how quickly we titrate.
The measurement that separates useful loss from the kind that comes back.
Eating much less means absorbing less. These get watched throughout.
Not labs, but they decide the outcome more than the dose does.
Read together, these tell us whether a GLP-1 is appropriate and what we need to protect while you are on it.
Protein first, and more than you think
So protein comes first, and the number is higher than most people expect: roughly a gram per pound of goal bodyweight, which is hard when a medication has removed your interest in food.
That difficulty is the actual work of the program, and it is why we plan meals rather than hope. Where insulin resistance is the driver underneath, the insulin picture is worth understanding first.
Load is the signal that saves muscle
Resistance training twice a week is the other half, and it does not need to be complicated or long. It needs to be heavy enough to give your body a reason to keep the tissue.
Walking is good for you and does not accomplish this. The signal that preserves muscle is load, and thirty minutes twice a week is enough to send it.
What changes when we work this way
Done this way, the weight that comes off is mostly fat, the scale moves more slowly, and what you keep afterwards is a body that still burns properly.
We retest at ninety days and track more than weight. Waist, strength, and body composition tell us whether the loss is the kind you want, and we adjust dose against that rather than against the scale alone.
Where to start
Bring your labs, especially fasting insulin and A1c, and be honest about what you are eating now. The protein target is the hardest part and I would rather plan for that than discover it in month two.
Then we sit down for half an hour, look at whether a GLP-1 fits, and write the protein and training plan that goes with it before anything gets prescribed.
