This episode covers what GLP-1s don't do for your body — and how to support the parts they leave to you. Nurse Doza walks through five areas the medication was never designed to handle: muscle, liver, gut, bone, and sleep. You'll learn why resistance training matters more once you start, how your gut makes GLP-1 on its own, the dopamine and "food noise" connection, and which nutrients support the work the injection can't do.
Featured Product
Gut (Digestive Health) by MSW Nutrition — $104
L-glutamine is the most abundant amino acid in your body, and your gut lining relies on it. Gut is single-ingredient L-glutamine — no fillers, no proprietary blend — formulated to support intestinal barrier integrity, healthy digestion, and your body's own glutathione production. When you're eating a lot less food overall, getting what your body needs takes more intention. Mix it in plain water on an empty stomach, first thing in the morning.

Join the School
If you're on a GLP-1 and nobody has walked you through the muscle, liver, and gut side of it, you're not alone — that conversation rarely fits into a 15-minute appointment. Inside the School of Doza, it's the conversation we're having every week.
Every Wednesday we host a live Ask Me Anything that runs like a group consult — labs, protein targets, supplements, what you're noticing on your medication. You bring the question, Nurse Doza answers it directly, live. These are live-only sessions, so you have to be in the room.
Every course. Plus Nurse Doza, every week. All-Access gets you every self-paced course in School of Doza, live Tuesday classes, and weekly AMAs with Nurse Doza. $35 a month, cancel anytime.

5 Key Takeaways
- A GLP-1 changes your appetite — it does not build muscle. Weight coming off includes muscle mass and bone density, which is why resistance training matters more once you start, not less.
- Research links GLP-1 receptor agonists to reduced visceral and liver fat, but your liver still needs nutrients — B9, B12, B6, magnesium, selenium — to do its actual work. The medication does not supply those.
- Your gut makes GLP-1 on its own. Gut enteroendocrine cells produce it after a meal, so gut health and your natural GLP-1 production are the same conversation.
- "Food noise" has a dopamine component. Your gut, brain, and adrenal glands all make dopamine, and research describes dopamine acting as an anti-incretin — meaning dopamine and GLP-1 move in opposite directions.
- Bones and sleep are the two areas nobody mentions. Weight-bearing exercise plus vitamin D3 and K2 support bone density, and poor sleep works directly against glucose control and appetite regulation.
