I am a board-certified obesity medicine physician. I have been prescribing GLP-1 receptor agonists — semaglutide, tirzepatide, and their predecessors — for years. I have watched these medications transform the lives of patients who had spent decades struggling with weight that was not a matter of willpower, but of biology. I have also watched the media cycle around these drugs produce more confusion than clarity.

Let me address the most common myths I encounter in my practice.

Myth 1: GLP-1 Medications Are "Just a Shortcut"

This framing reveals a fundamental misunderstanding of obesity as a disease. Obesity is not a character flaw. It is a complex, chronic, multifactorial condition with strong genetic, hormonal, and neurological components. GLP-1 receptor agonists work by mimicking a naturally occurring hormone that regulates appetite, gastric emptying, and insulin secretion. They correct a biological dysfunction — they do not bypass effort.

The patients I treat on GLP-1 medications still need to change their relationship with food. They still need to move their bodies. They still need to address the behavioral and psychological dimensions of eating. The medication creates a physiological environment in which those changes are possible for people for whom they were previously nearly impossible.

Myth 2: The Weight Always Comes Back When You Stop

This is partially true and requires nuance. Obesity is a chronic disease, and like most chronic diseases, it requires ongoing management. When GLP-1 medications are discontinued without a maintenance strategy in place, weight regain is common — studies show an average of about two-thirds of lost weight returning within a year of stopping. This is not a failure of the medication; it is the nature of the disease.

The appropriate response to this reality is not to avoid the medication — it is to plan for long-term management. Some patients transition to lower maintenance doses. Others use the medication cyclically. Others achieve sufficient lifestyle change during treatment that they can maintain their results without medication. This is individualized medicine, and it requires a physician who understands the full picture.

Myth 3: These Medications Are Dangerous

The safety profile of GLP-1 receptor agonists is well-established. The most common side effects are gastrointestinal — nausea, vomiting, constipation, diarrhea — and are typically dose-dependent and transient. Serious adverse events are rare. The concern about thyroid cancer, often cited in media coverage, is based on rodent studies at doses far exceeding clinical use; human data does not support this risk in patients without a personal or family history of medullary thyroid carcinoma.

The cardiovascular data for semaglutide is actually strongly positive — the SUSTAIN and SELECT trials demonstrated significant reductions in major adverse cardiovascular events in high-risk patients. For patients with obesity and cardiovascular risk factors, these medications may be among the most cardioprotective interventions available.

Obesity is a disease. Treating it with medicine is not cheating. It is medicine.

Myth 4: Anyone Can Get These Medications Online Without Medical Oversight

The proliferation of telehealth platforms prescribing compounded semaglutide without adequate evaluation is one of the most concerning trends I have observed. Appropriate prescribing of GLP-1 medications requires a thorough medical history, assessment of contraindications, baseline labs, and ongoing monitoring. Prescribing these medications without that foundation is not medicine — it is a transaction.

At The Skin Parlor™, physician-guided metabolic prescribing is embedded in the PHCM Metabolic Reset™ program, which includes physician evaluation, comprehensive metabolic labs, body composition assessment, and ongoing follow-up. The medication is one component of a medically supervised program, not a standalone product. Most insurance plans cover the medical visit; medication is self-pay.

The Bottom Line

GLP-1 medications are a genuine advance in the treatment of obesity. They are not magic, they are not without side effects, and they are not appropriate for everyone. But for the right patient, under appropriate medical supervision, they can be life-changing. If you are curious about whether you are a candidate, I invite you to schedule a consultation. Let's look at your history, your labs, and your goals — and make a decision based on evidence, not headlines.
