GLP-1 Medications: What an Obesity Medicine Doctor Wants You to Know
There's been a lot of noise around GLP-1 medications over the past few years. For some patients, they've felt like a miracle—real, meaningful weight loss after years of trying, with improvements in blood sugar, blood pressure, and how they feel overall. For others, the experience has been more complicated: side effects that didn't let up, a sense that things were happening too fast, or worry that these medications are too new to fully trust. Some see them as a long-overdue tool. Others see them as a money grab. For many patients, the cost itself is the problem—insurance dictates coverage, compounded formulations have flooded the market, and what's safe and what's not is a real question.
As a board-certified obesity medicine physician, I get asked about GLP-1s constantly. So here's what I'd want every patient to actually understand about them.
GLP-1s Are Not a New Class of Drug
The most common misconception is that GLP-1 medications are brand-new and untested. They aren't. This class of drug has been used to treat type 2 diabetes for more than two decades.
The earliest formulations were daily injections, which limited their use—many patients with diabetes simply couldn't or wouldn't manage a daily shot. When once-weekly versions came along, things changed. Researchers and clinicians began to notice that patients on these medications were also losing significant amounts of weight, sometimes for the first time in decades of trying.
That observation opened the door to a new generation of medications: GLP-1 receptor agonists, then dual GLP-1/GIP medications, and now newer combinations being developed for weight loss and for a growing list of metabolic conditions. So while weight-loss-specific GLP-1s feel new to the public, the underlying class has a long, well-studied track record.
What They Can Do
In the right patient, GLP-1 medications can be genuinely transformative. They're convenient (a weekly injection rather than daily dosing). They produce meaningful, often substantial weight loss—numbers we couldn't achieve with older weight-loss medications. They've been shown to improve a wide range of metabolic markers and reduce risk in several serious health conditions. And for many patients, they offer a less invasive option than bariatric surgery while delivering meaningful results.
Beyond diabetes and weight, evidence is growing for benefits in fatty liver disease, prediabetes, polycystic ovary syndrome (PCOS), cardiovascular disease, obstructive sleep apnea, and other metabolic conditions. More indications and newer formulations are on the horizon. This is one of the more exciting areas of medicine right now.
What They're Not
But these medications are not for everyone who struggles with weight or metabolic disease. Several realities tend to get lost in the marketing:
Side effects are common, particularly nausea, reflux, and gastrointestinal symptoms—and for some patients they don't resolve.
Not everyone tolerates dose increases. Some patients have to stay at a lower dose than the studies used.
Some patients don't respond. Not everyone sees significant weight loss on these medications, and we can't always predict who in advance.
Weight regain after stopping is common. These medications work while you take them. Obesity, like hypertension or diabetes, is a chronic condition—and like those conditions, some patients may need to stay on maintenance therapy for years to keep the benefit, even after their lifestyle pillars are firmly in place.
They aren't right for every patient. Certain medical conditions, medications, and life stages make GLP-1s a poor choice or unsafe.
The most important thing I want patients to understand: medication alone, without the foundations of nutrition, physical activity, sleep, and stress management, does not produce sustainable change. A GLP-1 can be a powerful tool, but it's a tool—not a substitute for the work underneath.
And not everyone needs to lose weight. Not everyone needs a GLP-1.
How Good Care With a GLP-1 Should Look
If a GLP-1 is the right fit for a patient, prescribing it is the beginning of the work, not the end of it. Good care looks like:
A slow, careful start with appropriate dose titration
Close monitoring for side effects and tolerance
Real attention to nutrition—including making sure protein intake is adequate as appetite drops
Strength training and movement to protect muscle mass and metabolic health
Sleep and stress as ongoing parts of the conversation
Regular follow-up, not a refill every few months
A plan for the long term, including what happens if the patient eventually wants to come off the medication
Obesity is a chronic, complex disease that is interconnected with many other metabolic conditions—fatty liver, prediabetes, type 2 diabetes, PCOS, sleep apnea, cardiovascular disease, and more. A medication that can help across that landscape is a real advance. But using it well requires a doctor who has the time to walk through nutrition, review what you're actually eating, talk through the realities of exercise, and follow up closely—not just send a refill.
Why I Built Anchor This Way
For years, I was uncomfortable watching GLP-1 access narrow to two extremes: online telehealth companies handing out prescriptions with minimal evaluation and no follow-up on one side, and traditional primary care offices that didn't have the time to use these medications well on the other.
In my own private practice, I knew what good GLP-1 care should look like—but I didn't have the time to actually deliver it. Reviewing food logs, having real conversations about exercise, adjusting doses thoughtfully, monitoring closely, troubleshooting side effects in real time: none of that fits into a fifteen-minute visit.
Direct primary care is what finally makes this kind of care possible. The time to do it right exists, the access to talk through questions exists, and the follow-up that these medications actually require can finally happen the way it should.
A GLP-1, used well and with the right partner, can change a life. Used poorly or in isolation, it falls far short of what it could be. The difference, almost always, is the relationship with the doctor.
