Are GLP-1 Medications the Best Solution for Weight Loss?

GLP-1 medications are everywhere.
Whether you’ve heard about Ozempic®, Wegovy®, Zepbound®, or Mounjaro®, these medications have become some of the most talked-about treatments for weight loss and diabetes management.
As a medical exercise specialist, nutrition coach, and someone who has personally used a GLP-1 medication, I’ve seen both the tremendous benefits and the challenges these medications present. The real question isn’t whether they work.
The question that matters most is this:
Are GLP-1 medications enough to create lasting weight loss?
What Are GLP-1 Medications?
GLP-1s, also known as semaglutides and newer dual agonists such as tirzepatide, are among the most talked-about medications in the world today.
These medications are prescribed for both diabetes management and weight loss and are available as injectable and oral medications.
Two of the most popular medications are Mounjaro® and Zepbound®.
Mounjaro is FDA-approved for Type 2 Diabetes, while Zepbound is approved for obesity, generally defined as a Body Mass Index (BMI) greater than 30.
Ironically, both medications contain the exact same active pharmaceutical ingredient—tirzepatide.
However, insurance coverage is often very different.
In many cases, Zepbound isn’t covered unless a patient meets specific medical criteria, such as severe obstructive sleep apnea. That means many patients pay between $400 and $450 per month, with costs increasing as dosage increases during step-up therapy from 2.5 mg to 15 mg.
What Does the Research Say About GLP-1 Weight Loss?
Eli Lilly, the manufacturer of both Mounjaro and Zepbound, reported an average weight loss of approximately 21% among patients taking the highest 15 mg dosage during a 72-week clinical trial when combined with proper diet and exercise.
For someone weighing 200 pounds, that’s roughly 44 pounds over approximately 17 months.
In my opinion, that pace of weight loss wouldn’t justify the monthly cost for many people if they aren’t simultaneously learning healthier eating habits and exercise behaviors that will last after the medication ends.
One important point often overlooked is that participants in Eli Lilly’s SURMOUNT-4 trial were instructed to perform at least 150 minutes of exercise every week.
Exercise wasn’t optional.
It was part of the treatment plan.
Why Long-Term Lifestyle Changes Matter
During my career, I’ve coached numerous Scottsdale Active Aging clients through medically supervised weight loss programs.
Many have lost close to 100 pounds while learning sustainable nutrition, resistance training, metabolic exercise, and lifestyle habits that allowed them to keep the weight off.
Those results weren’t achieved because of a medication alone.
They were achieved because the medication, when used, as combined with lasting behavioral change.
Another important finding from the SURMOUNT-4 study showed that many participants regained weight after stopping treatment.
Clinical follow-up demonstrated that many patients regained a significant portion of the weight they had lost within one year after discontinuing therapy.
To me, this reinforces one important lesson:
GLP-1 medications can be an excellent tool, but they cannot replace healthy habits.

My Personal Experience Taking Zepbound
As a medical professional, fitness coach, nutritionist, and GLP-1 specialist, I felt it was important to understand these medications firsthand.
I personally took Zepbound as part of my own research and professional development.
I lost 35 pounds in one month’s time.
It didn’t come easy.
Fortunately, I had the advantage of understanding exercise physiology, nutrition, medical monitoring, and the determination to continually adjust my program as my body adapted.
That experience taught me something many patients don’t realize:
Success with GLP-1 medications requires much more than simply taking an injection each week.
Understanding the Side Effects
GLP-1 medications affect both the brain and the digestive system.
Together they help regulate appetite while reducing food cravings through dopamine modulation and changes in gastric emptying.
Unfortunately, nearly every patient experiences some degree of side effects.
Common symptoms include:
- Nausea
- Fatigue
- Brain fog
- Muscle weakness
- Lethargy
- Reduced motivation (anhedonia)
These symptoms can interfere with work, exercise, sleep, and overall quality of life.
Fortunately, many of these side effects can be minimized through proper hydration, electrolyte management, nutrition, exercise programming, and medical supervision.
Why Medical Monitoring Is So Important
Anyone considering GLP-1 therapy should work closely with their primary care provider.
Baseline laboratory testing is extremely important and should include monitoring such as:
- Hemoglobin A1C
- C-Reactive Protein (CRP)
- Lipid Profile
- Comprehensive Thyroid Panel
These values should be re-evaluated approximately every six months or as recommended by your physician.
Certain foods can dramatically worsen symptoms.
Electrolyte imbalances may contribute to cardiac rhythm abnormalities.
Improper exercise programming while taking GLP-1 medications can accelerate muscle glycogen depletion, increasing the risk of hypoglycemia and other complications.
Having a knowledgeable healthcare provider and fitness professional on your team can make a tremendous difference.
Are GLP-1 Medications the Future?
Without question.
GLP-1 medications are here to stay.
New GLP-1, GIP, and glucagon agonists continue moving through FDA approval, and the science behind metabolic medicine continues advancing rapidly.
The medications will improve.
The question is whether our habits improve with them.
What I tell My Clients
GLP-1 medications are simply a tool.
They are not a replacement for discipline.
They are not a replacement for nutrition.
They are not a replacement for exercise.
They are not a replacement for quality sleep.
Just like artificial intelligence will never replace human creativity, GLP-1 medications will never replace the fundamentals of nutrition, exercise physiology, sleep recovery, and mindset.
Used correctly, they can become an outstanding tool within a comprehensive weight-loss program.
Used alone, they often become a temporary solution to a lifelong problem.
