Why “the scale going down” doesn’t always mean health is improving
The role of exercise and muscle preservation on GLP-1s
How slowed digestion can affect nutrient absorption
What bariatric patients should keep in mind when using GLP-1 medications

How clinicians are thinking about long-term use, lower dosing, and maintenance

Show notes

Send us Fan Mail

If you’ve noticed your pain improving on a GLP-1 medication, you may not be imagining it, and it may not be just because of weight loss. In this episode, Ana sits down with Dr. Asare Christian, an integrative pain management physician, to talk about why chronic pain is often treated too narrowly, how inflammation, sleep, trauma, stress, and metabolic health all shape the pain experience, and why GLP-1 medications like semaglutide may have a direct pain-relieving effect even at low doses. They also dig into migraines, how low-dose semaglutide may fit into pain care, the micronutrients that still matter when appetite is lower, and why lasting pain relief usually takes more than a single medication or procedure.

Show notes

Send us Fan Mail

GLP-1 medications can be life-changing, but rapid weight loss can also mean losing muscle if you are not actively protecting it. In this episode, Ana Reisdorf sits down with registered dietitian Jennifer Scheinman to talk about why muscle strength matters just as much as muscle mass, how mitochondria influence energy, mobility, and healthy aging, and what GLP-1 users can do right now to support muscle with a balanced diet, enough protein, exercise, and smart supplementation. They also break down the emerging research on urolithin A, including how it may support mitochondrial recycling and muscle strength, why that matters for fatigue and long-term function, and where it may fit into a practical GLP-1 lifestyle.

Dietary Fats on a GLP-1s: What to Eat and Why w/ Dr. Renee Korczak Mar 19, 2026

Show notes

Send us Fan Mail

Fat is one of the most misunderstood macronutrients, and when you're eating less on a GLP-1, choosing the right fats matters more than ever. In this episode, Ana sits down with Dr. Renee Korczak, PhD, RDN, to cut through the noise around dietary fats. They cover the four main types of fat, why unsaturated fats (MUFAs and PUFAs) should make up the bulk of what you eat, how to handle the protein-plus-saturated-fat challenge on a GLP-1, where omega-3s fit in, and how to approach the micronutrient deficiencies GLP-1 users are increasingly running into. They also tackle the beef tallow trend head-on and make a strong case for why the low-fat era of the 90s was both wrong and unforgettable. If you've been unsure whether to count fat, fear fat, or just eat the avocado, this episode gives you a practical, science-backed framework you can actually use.

About Our Guest:
Dr. Renee Korczak is an advanced practice registered dietitian nutritionist with a PhD in human nutrition from the University of Minnesota. She specializes in translating complex nutrition science into clear, actionable guidance for consumers and health professionals.
