GLP-1 & Weight Loss
GLP-1 & WEIGHT LOSS
The medication works. Whether it lasts depends on everything around it.
Semaglutide and tirzepatide changed what is possible. They also come with real questions: muscle loss, side effects, plateaus, and what happens when you stop. Used well, inside a plan that protects your metabolism, they are one of the most powerful tools we have. Used alone, the weight often comes back.

Start with what GLP-1 medications actually do, where they help, and the mistakes that turn a powerful tool into a temporary fix. This is the balanced, root-cause view from a physician who works in this research.

What GLP-1 medications actually do
GLP-1 medications mimic a gut hormone that slows digestion, signals fullness, and steadies blood sugar, so appetite drops and weight follows. For many people that is genuinely life-changing. But weight is a downstream symptom of metabolic dysfunction, and a drug that quiets appetite does not by itself repair the mitochondria, muscle, and insulin signaling underneath.
The risks worth managing are real: losing muscle along with fat, nutrient gaps from simply eating less, and regain when the medication stops. Used inside a plan that protects muscle with protein and resistance training, leans on real food, and addresses the root metabolic drivers, GLP-1 becomes a launchpad rather than a lifelong dependency.
What patients ask us about
- Losing muscle, not just fat
- Side effects and tolerability
- What to eat while on it
- Plateaus
- What happens when you stop
- Long-term safety
- Dosing and titration
- Protecting metabolism
Commercial weight-loss clinics start patients at 7 to 10 mg of tirzepatide. Aaron starts at 0.25 to 0.5 mg. Standard doses run 30 to 40 times above the body’s own physiologic baseline, which is where most of the serious side effects come from.

Your gut makes its own GLP-1.
Certain gut bacteria produce GLP-1 in your digestive tract, which is why the microbiome matters whether or not you are on a medication. See the strains Aaron looks at and how to support your body’s own production.
