Some of the most important GLP-1 questions don't fit neatly into a topic category. They're the questions people type into Reddit at midnight, the ones that don't get a real answer in a 10-minute appointment, and the ones a good agent needs to handle accurately.
This section covers them directly.
What's covered
Why You're Not Losing Weight on GLP-1s
The drug is working. Something else is getting in the way. Thyroid dysfunction, insulin resistance, under-eating, wrong dose, and the handful of other reasons weight loss stalls — with what to do about each.
Supplements Worth Taking on GLP-1s
Most supplements are irrelevant. A few actually matter when you're on a GLP-1 and eating significantly less than before. What the evidence supports — creatine, omega-3s, vitamin D, magnesium, protein — and what's just expensive noise.
Fasting and Meal Timing on GLP-1s
Does intermittent fasting work alongside GLP-1 therapy? Does meal timing matter? What the research says about combining the two approaches, and when fasting helps vs. compounds the under-eating problem.
Drug Interactions on GLP-1s
What not to combine with a GLP-1 drug — medications, supplements, and behaviors that interact with the mechanism or increase risk. Some of these are well-documented. Some are patterns the clinical community has noticed without a full evidence base yet.
GLP-1 Myths, Addressed
The most persistent misconceptions about GLP-1 drugs — from "it's cheating" to "you'll regain everything" to "it's destroying your muscles." Where each myth comes from, what the actual evidence says, and why some of them contain a grain of truth that gets distorted.
Before You Start a GLP-1
What to do, ask, and know before your first injection — contraindications, what to tell your provider, how to set realistic expectations, what to have in place, and what the first four weeks actually feel like.
Clinical depth
The Cardiovascular and Kidney Benefits of GLP-1s
SELECT, FLOW, LEADER, SUSTAIN-6 — the cardiovascular outcome trials that found GLP-1 drugs actively reduce heart attacks, strokes, and kidney disease progression. What the mechanism is, what it means for patients without diabetes, and the early neurological signals.
GLP-1s vs. Bariatric Surgery
Surgery still wins on raw efficacy numbers. GLP-1s win on reversibility and risk profile. The actual comparison — durability, who each option suits, and how GLP-1s are increasingly used before and after surgery.
Cortisol, Stress, and Weight Loss on GLP-1s
What cortisol actually does to metabolism, why "adrenal fatigue" is not a real diagnosis, when elevated cortisol genuinely stalls GLP-1 therapy, and what interventions actually work.
Traveling on GLP-1s
TSA rules, temperature windows for in-use and unopened pens, FRIO wallets, time zone injection shifts, missed-dose windows by drug, and international supply planning.
Niche but important
Can GLP-1 Drugs Affect Your Vision?
The 2024 NAION study explained — what it actually showed, what it didn't establish, who is genuinely at risk, and what diabetic retinopathy risk is distinct and better-documented. What symptoms to watch for and when to see an eye doctor.
Compounding Pharmacies and GLP-1 Access
How compounded semaglutide and tirzepatide differ from brand-name, where the legal framework stands post-shortage, documented quality concerns, how to evaluate a compounding pharmacy, and what patient assistance programs exist as alternatives.
What the Long-Term Data on GLP-1s Actually Shows
Three-year tirzepatide data, what fades vs. what holds at extended follow-up, the emerging safety picture, and what remains genuinely unknown about decade-plus use.
GLP-1s in Children and Adolescents
What the STEP TEENS trial showed, which drugs are approved for which ages, the legitimate growth and development questions, the ethical debate addressed directly, and practical considerations for families navigating this decision.
