The School of Doza Podcast

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.

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.

In this School of Doza episode, Nurse Doza kicks off a new series on the health numbers that matter more than the scale. Using the Hume Pod and app, he explains how body composition (body fat percentage, skeletal muscle mass, and visceral fat) tells a fuller story than weight alone, why two people at the same weight can differ, and a simple morning weigh-in habit that tracks trends, not daily swings. Next up: how these numbers connect to your liver and blood sugar.

5 KEY TAKEAWAYS

Weight is just one number. The scale can't show what your weight is made of, and two people at the same weight can have very different body compositions.

Body composition adds the missing detail. Beyond weight, the Hume Pod reports body fat percentage, skeletal muscle mass, and visceral fat, giving a more complete picture of where you stand.

Visceral fat is the one you can't see. It sits deep in the abdomen around the organs, is associated with insulin resistance and fatty liver, and can be present even in people who look lean.

Trends beat daily numbers. Nurse Doza suggests weighing in the same way, at the same time each morning, then watching the trend in muscle and visceral fat rather than fixating on the weight itself.

This is Part 1 of a series. Up next, he connects these numbers to liver health and blood sugar.

Fatty liver and belly fat tend to show up together, and this episode makes the case that it isn't a coincidence. Your liver is one of the main places your body decides whether fat gets stored, moved, or burned for fuel. Nurse Doza walks through six things that get in the liver's way — insulin resistance, too little brown fat, gut damage, eating when you're not hungry, poor methylation, and shallow sleep — and what the research says about each one.

FEATURED PRODUCT
Liver Boost (Detox) — $111

Sixteen ingredients in a single capsule — milk thistle, NAC, alpha-lipoic acid, turmeric, broccoli seed extract, green tea extract, selenium — formulated to support phase I and phase II liver detoxification and your body's own glutathione production.*

This whole episode is about clearing the path for the organ doing the work. Liver Boost is support for that organ while you change the sleep, the food, and the fasting window. One to two capsules a day.

Through October 31: buy 2, get 1 free — 3 bottles for $222, roughly a six-month supply. No code needed; the discount applies at checkout.

If this episode left you looking at a lab report that never had fasting insulin or leptin on it, that gap is exactly what the School of Doza was built for. Same for the belly fat that hasn't moved in a year of doing everything right.

Every Wednesday there's a live Ask Me Anything that runs like a group consult — labs, nutrition, supplements, liver questions, belly fat questions. You bring it, Nurse Doza answers it directly. It's live only and never recorded, so being in the room is the whole point.

5 KEY TAKEAWAYS

Insulin resistance usually shows up before the weight does. Research associates fatty liver with higher insulin resistance, and the early liver changes often appear ahead of obesity — which is part of why "eat less, move more" stalls out for so many people.

Fat tissue behaves like an organ, not a storage closet. Inflamed white fat around the middle loses some of its ability to help regulate insulin, and cold exposure is associated with more brown fat activity and better clearance of circulating glucose and triglycerides.

The gut tends to struggle first. Dysbiosis and a compromised gut lining are linked to liver fat and inflammation, and your gut microbiome is part of your own GLP-1 production — which is rarely part of the conversation.

Leptin is insulin's shadow. It rises when you eat, it tracks with how much body fat you carry, and leptin resistance is why people end up eating on schedule instead of on hunger. Neither leptin nor fasting insulin is on a standard panel.

Methylation and deep sleep are the two clearance pathways nobody checks. MTHFR variants are associated with higher fatty liver risk, and short sleep duration is associated with fatty liver — so the overnight hours matter as much as the plate.

Muscle after 40 is the thing women are told to ignore, and it is the one that changes everything. Nurse Doza breaks down why skeletal muscle is an organ, how it makes its own estrogen, why insulin resistance shows up in muscle first, and how much protein menopause actually calls for. Plus the amino acid most women have never been told about.

Featured Product
Liver Boost (Detox) by MSW Nutrition — a comprehensive formula designed to support phase I and phase II liver detoxification of environmental toxins.* Estrogen doesn't simply disappear once it has done its job: it gets conjugated in the liver and cleared through bile. This episode is about the estrogen your muscles make, and the liver is the organ standing at the end of that pathway — the same organ Nurse Doza points back to when he talks about glycogen, fatty liver, and hormones in your forties.

5 Key Takeaways

Your muscles are an organ, not just tissue. Skeletal muscle is a collection of muscle, connective, nervous and vascular tissue working together, and it releases signaling molecules of its own. Treating it as decoration misses what it actually does for posture, structure, and metabolism.

Skeletal muscle makes its own estrogen. Beyond the ovaries, muscle carries the enzymes to produce what researchers call myogenic estrogen. Exercise appears to support that local production, which in turn supports muscle mass, function, metabolism, and repair — a loop that matters most for women after menopause.

Menopause raises the protein bar. The general recommendation is 1.0 to 1.2 grams of protein per kilogram of body weight per day. At 150 pounds that is roughly 68 to 81 grams daily, which is four to five eggs in the morning and something comparable at every other meal.

Insulin resistance shows up in muscle first. Skeletal muscle is where most insulin-driven glucose uptake happens, so it is also where impaired glucose handling appears earliest — often years before anything shows on a routine panel. As estrogen falls, insulin sensitivity tends to fall with it, which is part of why weight becomes harder to manage in the forties.

Toning versus bulking is a programming decision. Moderate weight, 8 to 12 reps, 2 to 3 sets, bodyweight and banded work mixed in — that builds strength and shape without the volume and intensity that drive maximum size. Bulk is something you train for on purpose, not something that happens by accident.

In this Wellness Tech Series episode, Nurse Doza breaks down the Hume Band and why daily health data changes how he makes decisions. He walks through the metrics he checks every morning — sleep depth and wake-ups, heart rate variability as a window into stress and recovery, pulse oximetry day and night, body temperature, and steps — then explains how the Hume Pod adds body fat, skeletal muscle mass, and visceral fat. Labs are a snapshot; this is the daily trend line underneath them.

## 5 Key Takeaways

 

1. **Labs are a snapshot; wearables are the trend line.** A panel drawn twice a year can't tell you what last night did to your recovery. Daily metrics fill in the space between blood draws.

2. **Sleep isn't one number.** Total hours matter, but so do depth, light sleep, and how many times you were awake. Seeing the breakdown each morning is what makes the adjustment obvious.

3. **HRV reads both sides of the day.** Overnight HRV reflects recovery; daytime HRV reflects the stress load you're carrying right now. Watching both separately is more useful than either alone.

4. **Pulse ox is the quietly important one.** Continuous oxygen saturation — especially overnight — is a pattern worth bringing to your provider if you snore or wake up unrefreshed. Screening data is a conversation starter, not a diagnosis.

5. **The Pod covers what the band can't.** Body fat percentage, skeletal muscle mass, and visceral fat round out the metabolic picture. Visceral fat in particular is the depot most consistently associated with insulin resistance and fatty liver in the research.
