What Are GLP-1 Weight Loss Medications?
GLP-1 (glucagon-like peptide-1) receptor agonists is a class of injectable or oral prescription medications that mimic a naturally occurring gut hormone. When you eat, your body releases hormones to signal fullness and stimulate insulin production. These medications do the same – curbing appetite, slowing your digestion, and helping you to consistently eat less over time.
GLP-1 drugs were developed to treat Type 2 diabetes, but their weight loss benefits led to FDA approval for chronic weight management. As of 2025, semaglutide became the first oral GLP-1 receptor agonist approved for obesity treatment.
Is Ozempic Approved for Weight Loss?
Ozempic is the most recognized GLP-1 medications on the market, but you should understand how physicians prescribe it. Ozempic (semaglutide) is FDA-approved specifically for the management of Type 2 diabetes, not as a primary weight loss treatment. However, its weight-reducing effects are well-documented, and many physicians prescribe it off-label for weight management.
The FDA-approved version of semaglutide for weight loss is Wegovy, which delivers a higher 2.4 mg weekly dose. Key facts about Ozempic/semaglutide for weight loss:
- Administered as a once-weekly subcutaneous injection
- Originally approved for blood sugar control in Type 2 diabetes patients
- Off-label use for weight loss is common but not FDA-indicated at Ozempic’s standard doses
- Wegovy (semaglutide 2.4 mg) is the approved weight-loss formulation
- Both work by activating GLP-1 receptors to reduce appetite and promote fullness
If you’re considering Ozempic or Wegovy, a consultation with a qualified physician is essential to determine which formulation is appropriate for you.
What Is Semaglutide for Weight Loss?
Semaglutide – the active ingredient in both Ozempic and Wegovy – is currently one of the most clinically studied GLP-1 medications for weight loss. In landmark clinical trials, patients taking semaglutide 2.4 mg lost an average of 14 to 16% of their body weight over 68 weeks, delivering results that far exceed older weight-loss medications.
Long-term data shows that patients maintained approximately 10 to 12% weight loss over 4 years while on semaglutide.
Semaglutide works by:
- Binding to GLP-1 receptors in the brain and gut to suppress appetite for up to 1 week per dose
- Slowing gastric emptying so you feel full longer after eating
- Reducing cravings and improving blood sugar regulation
- Supporting meaningful, sustained weight loss when combined with lifestyle changes
Semaglutide is also available as an oral pill (brand name Rybelsus) for diabetes, and an oral weight-loss formulation was submitted for FDA review in 2025.

What Is the Best GLP-1 for Weight Loss?
Optimal GLP-1 medication depends on your health history, weight loss goals, and how your body responds to treatment. Currently, the three leading options prescribed specifically for weight loss are:
Semaglutide (Ozempic/Wegovy)
- Average weight loss: 14 to 16% of body weight
- FDA-approved for chronic weight management
Tirzepatide (Zepbound)
- Average weight loss: 20 to 22% of body weight
- FDA-approved for chronic weight management
A dual GLP-1/GIP receptor agonist that has shown superior weight loss results compared to semaglutide alone – roughly 20% body weight reduction vs. 14% for semaglutide in head-to-head trials
Liraglutide (Saxenda)
- Average weight loss: 5 to 8% of body weight
- FDA-approved for chronic weight management
A generic version was approved by the FDA in August 2025, making it a more accessible option for some patients
Dr. Bridge will evaluate your BMI, metabolic health, insurance coverage, and medical history to recommend the most appropriate medication for your specific needs.
How Much Weight Can You Lose on GLP-1?
Results vary by individual, medication, dose, and commitment to healthy lifestyle habits, but the clinical data is compelling. Here’s what research shows:
- Semaglutide (Ozempic/Wegovy): Average loss of 14 to 16% body weight over 68 weeks
- Tirzepatide (Zepbound): Average loss of 20% body weight over a similar period
- 8% of semaglutide patients lost at least 5% of body weight, 44.2% lost at least 10%, and 22.9% lost at least 15%
- One study found patients lost an average of 15 lbs. after 3 months and 27 lbs. after longer-term use
For patients who have achieved significant weight loss on GLP-1s and are left with loose skin or contour irregularities, body contouring procedures like liposuction or a tummy tuck performed by Dr. Kevin Bridge may help you refine and complete your transformation.
Who Qualifies for GLP-1 Weight Loss Medications?
GLP-1 weight loss medications are not available over the counter, and they require a prescription from a licensed provider. FDA guidelines specify that patients who may qualify include:
- Adults with a BMI of 30 or higher (classified as obese)
- Adults with a BMI of 27 or higher plus at least one weight-related health condition, such as high blood pressure, Type 2 diabetes, or high cholesterol
- Adolescents age 12 and older (for certain medications), with physician oversight
You may NOT qualify if you have:
- A personal or family history of medullary thyroid carcinoma (MTC)
- Multiple endocrine neoplasia syndrome type 2 (MEN 2)
- A history of pancreatitis
- Pregnancy or plans to become pregnant
A full medical evaluation, including bloodwork and a review of your current medications, is required before a GLP-1 prescription can be issued. Speak with your primary care provider or a weight management specialist to find out if you are a candidate.
Can You Get GLP-1 Weight Loss Medications Without Insurance?
GLP-1 medications can be costly without insurance coverage. Out-of-pocket costs typically range from $900 to $1,400 per month, or up to $12,000 per year for brand-name options like Wegovy or Zepbound.
Ways to reduce your GLP-1 costs:
- Manufacturer savings cards: Novo Nordisk and Eli Lilly offer discount programs for eligible patients
- Patient assistance programs: Income-based programs may provide medications at reduced or no cost
- Generic alternatives: The FDA approved a generic form of liraglutide (Saxenda) in 2025, which may lower costs for some patient
- Compounding pharmacies: Some patients use compounded semaglutide, though the FDA has raised concerns about unapproved compounded versions
- Check your insurance: Some plans cover GLP-1s for diabetes management even if they don’t cover them for weight loss. Call your insurer directly to confirm
With insurance, copay for GLP-1 medications typically ranges from $25 to $150 per month, depending on your plan’s formulary tier and deductible.
