See Common Questions Compare GLP-1 Medications

A

Appetite Regulation

Mimics a natural gut hormone to curb hunger and increase feelings of fullness after eating—without relying on stimulants.

S

Sustained, Clinically-Proven Results

Demonstrated average weight loss of 10–15% in major studies, helping patients surpass typical results of older medications.

M

Metabolic Health Benefits

Improves blood sugar control and cardiovascular risk factors, making GLP-1 therapy uniquely valuable for patients with diabetes or heart risk.

T

Tailored, Prescription-Only Approach

Therapy is individualized—prescribed and titrated for you by a medical professional based on health history and goals.

GLP-1 Receptor Agonists

What Are GLP-1 Medications?

GLP-1 (glucagon-like peptide-1) medications belong to a class of prescription drugs originally developed for type 2 diabetes. They work by mimicking a naturally occurring hormone that signals satiety (fullness) to the brain and slows digestion, ultimately reducing appetite and calorie intake.

But in the last few years, GLP-1 receptor agonists—such as semaglutide (Ozempic, Wegovy), liraglutide (Saxenda, Victoza), and tirzepatide (Mounjaro, Zepbound)—have been approved and widely adopted for weight management in patients with obesity or overweight and related conditions. These medications mark the most significant advance in prescription-based weight loss in over a decade.

Unlike older stimulant or appetite suppressant drugs, GLP-1s act on the body's own chemistry to produce real, lasting results.

FDA-Approved Treatments

How Do They Promote Weight Loss?

GLP-1 medications act on multiple pathways that collectively make losing weight not just possible but sustainable:

They suppress appetite by enhancing satiety signals in the brain's hypothalamus.
They slow gastric emptying, so you feel fuller, longer.
They modulate insulin and glucagon secretion, stabilizing blood sugar and reducing food cravings.

These effects combine to lower daily calorie intake—without the jittery side effects of stimulants. As a result, patients on GLP-1 therapy typically experience a steady, significant reduction in body weight over time.

GLP-1s vs. Other Prescription Weight Loss Drugs

Medication	Avg. Weight Loss*	Notable Benefits	Typical Route
GLP-1s (Semaglutide, Liraglutide)	10–15%	Appetite, glucose & heart health	Injection or oral
Bupropion/Naltrexone	5–9%	Mood, cravings	Oral
Phentermine/Topiramate	8–10%	Energy, appetite	Oral
Older anti-obesity drugs	3–7%	Short-term use	Oral

01

Semaglutide

Wegovy & Ozempic

Branded as Wegovy (for weight loss) and Ozempic (for diabetes), semaglutide is the first GLP-1 to demonstrate average 15% body weight loss in pivotal trials. Self-administered as a weekly injection, it's become the most referenced modern therapy for obesity.

02

Tirzepatide

Mounjaro & Zepbound

Tirzepatide acts on both GLP-1 and GIP receptors, yielding the most dramatic weight loss—up to 22% in some trials. Approved for diabetes and obesity, it is currently prescribed for those who have not succeeded with other therapies.

03

Liraglutide

Saxenda & Victoza

The first daily injectable GLP-1 approved for obesity, liraglutide produces 5–10% weight loss on average. It remains an important option for those requiring daily dosing or with contraindications to other GLP-1s.

Frequently Asked Questions

GLP-1 Weight Loss: Key Answers

What is a GLP-1 medication and how does it promote weight loss?

GLP-1 medications mimic a natural hormone that helps regulate appetite and blood sugar. They signal fullness to the brain, slow stomach emptying, and reduce hunger, leading to significant weight loss for many patients.

How effective are GLP-1 drugs for obesity treatment?

Clinical trials show GLP-1 drugs like semaglutide and liraglutide can help patients lose 10% to 15% or more of their starting body weight when combined with lifestyle changes, outperforming most previous prescription options.

Are there side effects or risks to GLP-1 weight loss medications?

The most common side effects are mild to moderate nausea or GI symptoms, which usually fade with time. Rare but serious risks include pancreatitis or gallbladder issues. A doctor's guidance is essential for safe use.

Who is eligible for GLP-1 weight loss therapy?

Typically, GLP-1 weight loss therapy is prescribed to adults with obesity (BMI ≥30) or overweight (BMI ≥27) with at least one weight-related condition such as type 2 diabetes, high blood pressure, or cardiovascular risk.

How does GLP-1 treatment compare to other weight loss drugs?

GLP-1 medications generally result in more weight loss than older prescription drugs and offer metabolic benefits but must be prescribed and monitored by a healthcare provider to ensure safety.
