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:

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

We talk about:

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