124: GLP-1s Aren’t the Problem. Using Them Wrong Is (Muscle Loss, Thyroid, Rebound Weight Gain)

GLP-1 medications and peptides are changing modern medicine, but many people are using them in a way that quietly sabotages health. In this episode of The Lizzie Ens Show, Lizzie breaks down why GLP-1s are not inherently “bad,” and why the real danger is taking doses that suppress appetite so aggressively you stop eating, skip protein, avoid strength training, and never address the root causes behind weight gain.

She explains why common GLP-1 “side effects” are often the downstream effects of undereating, dehydration, slowed digestion, nutrient depletion, and muscle loss, including constipation, nausea, dizziness, fatigue, reflux, hair loss, and the “skinny fat” outcome (lower scale weight but higher body fat and low lean mass).

Lizzie also covers the long game: what happens when someone stops using GLP-1s without building foundational habits first, and why rebound weight gain can happen rapidly. If you want fat loss without sacrificing metabolism, thyroid health, and muscle, this episode lays out what to do before, during, and after a GLP-1 journey.

In this episode, you’ll discover:

1. Why “I can’t eat for two days” is a sign your dose may be too high
2. Why constipation on GLP-1s often comes from not eating enough (and not hydrating enough)
3. What causes nausea, dizziness, fatigue, and brain fog, and how to reduce them
4. Why hair loss is often driven by macro + micronutrient deficiency, not “the drug itself”
5. How low intake can contribute to depleted B vitamins and iron issues
6. How muscle loss happens on GLP-1s, and why it matters for long-term health
7. The “skinny fat” trap, losing weight while losing strength and metabolic power
8. Why rebound weight gain can happen after stopping Ozempic-like meds, and how to prevent it
9. The link between undereating and anxiety, depression, and dopamine disruption
10. Why your thyroid is the “fire” of metabolism, and how long deficits can backfire
11. Why peptides should be the “cherry on top,” not the foundation
12. When GLP-1s may not work well at all (hidden stress load, toxins, and other root issues)

We talk about:

1. 00:00 Why fast weight loss is not the same as fixing metabolism
2. 01:10 Safety and sourcing concerns, why guidance matters
3. 03:00 What happens when appetite is shut down and the body is underfed
4. 04:30 Constipation, digestion slowdown, nausea, dizziness, and dose red flags
5. 06:00 Hair loss, nutrient depletion, and muscle loss tradeoffs
6. 07:30 Rebound weight gain after stopping, what drives it
7. 09:00 The return of “skinny obsession,” and why that is not health
8. 10:10 The non-negotiables, protein, hydration, strength training, sleep
9. 11:20 Anxiety and depression, how underfueling amplifies symptoms
10. 12:20 Reflux and fasting-like symptoms even when you’re barely eating
11. 13:10 Thyroid health, metabolic slowdown, and the cost of long deficits
12. 14:20 Psychological costs, fear of food, loss of hunger cues, dependency
13. 15:30 Microdosing vs high-dose use, why strategy matters
14. 16:40 Peptides as support, not a replacement for foundations
15. 18:00 Why testing matters, uncovering root causes that block progress
16. 21:00 Final guidance, protect muscle, protect thyroid, build sustainability
