Weight loss medications are dominating conversations in the fitness and health world. From Ozempic® and Wegovy® to Zepbound®, more people are asking whether these medications can help them achieve lasting weight loss.
One of the biggest questions we hear at Union Studio is:
“What’s the difference between GLP-1 and GLP-3?”
Technically, there is no FDA-approved “GLP-3” medication class. Most people are referring to newer medications like tirzepatide (Zepbound® and Mounjaro®), which target both the GLP-1 and GIP receptors rather than GLP-1 alone. These dual-action medications are producing impressive results for both weight loss and blood sugar control.
What Is a GLP-1 Medication?
GLP-1 (Glucagon-Like Peptide-1) is a hormone naturally produced in your gut after eating.
Medications such as:
- Ozempic
- Wegovy
- Saxenda
work by:
Slowing stomach emptying
Helping you feel fuller longer
Reducing appetite
Improving blood sugar regulation
These effects can make it easier to maintain a calorie deficit and lose weight.
What Are Dual GLP-1/GIP Medications?
The newest generation of weight-loss medications combines GLP-1 with another hormone called GIP (Glucose-Dependent Insulinotropic Polypeptide).
Examples include:
- Zepbound
- Mounjaro
These medications activate both hormone pathways simultaneously, helping regulate hunger, improve insulin response, and potentially enhance weight loss beyond traditional GLP-1 medications.
GLP-1 vs Dual GLP-1/GIP: Key Differences
| Feature | GLP-1 Medications | Dual GLP-1/GIP Medications |
|---|---|---|
| Appetite Control | Excellent | Excellent |
| Blood Sugar Control | Excellent | Excellent |
| Hormone Targets | 1 | 2 |
| Weight Loss Potential | Significant | Often Greater |
| Examples | Wegovy, Ozempic | Zepbound, Mounjaro |
Clinical studies have shown tirzepatide can produce greater average weight loss than semaglutide in many patients, though individual results vary greatly.
The Fitness Side of the Conversation
One concern frequently discussed by fitness professionals is the potential loss of lean muscle mass during rapid weight loss.
Fitness expert Jillian Michaels has emphasized the importance of combining these medications with strength training and adequate protein intake to help preserve muscle while losing fat.
At Union Studio, we couldn’t agree more.
Weight loss alone shouldn’t be the goal.
The real goal is:
- Losing body fat
- Preserving muscle
- Improving strength
- Increasing energy
- Enhancing long-term health
Whether you’re using medication or not, resistance training remains one of the most effective tools for maintaining metabolism and functional fitness.
Are These Medications a Magic Solution?
No.
The most successful long-term outcomes occur when medications are paired with:
Strength training
Cardiovascular exercise
Adequate protein intake
Healthy sleep habits
Sustainable nutrition
Many users report that medications help reduce “food noise” and cravings, making it easier to stick with healthy habits. However, exercise remains critical for maintaining muscle, bone density, cardiovascular health, and overall quality of life.
