‍GLP-1 (Glucagon-Like Peptide-1) receptor agonists are a class of medications originally developed to treat type 2 diabetes, but they are now widely used for weight management and obesity treatment.

Popular GLP-1 medications include:

• Semaglutide (Ozempic®, Wegovy®)
• Tirzepatide (Mounjaro®, Zepbound®)*
• Liraglutide (Saxenda®, Victoza®)

*Technically, tirzepatide is a dual GIP/GLP-1 receptor agonist, but it's often discussed alongside GLP-1s.

How Do GLP-1 Medications Work?

GLP-1 is a natural hormone your body releases after eating.

GLP-1 medications mimic this hormone and help:

Reduce Appetite

• Decrease hunger signals in the brain
• Increase feelings of fullness (satiety)

Slow Stomach Emptying

• Food stays in the stomach longer
• You feel satisfied for a longer period

Improve Blood Sugar Control

• Stimulate insulin release when needed
• Reduce excess glucose production by the liver

The result is that many people naturally eat less without feeling as deprived as with traditional dieting.

Benefits of GLP-1 Therapy

Weight Loss

• Significant reduction in body weight
• Helps reduce stubborn fat stores

Appetite Control

• Reduced food cravings
• Better portion control
• Less "food noise" (constant thoughts about food)

Metabolic Health

• Improved blood sugar control
• Improved insulin sensitivity
• Reduced risk factors associated with obesity

Cardiovascular Benefits

Some GLP-1 medications have been shown to:

• Reduce risk of major cardiovascular events
• Improve certain heart-health markers

What GLP-1 Is Commonly Used For

Weight Management

• Overweight individuals
• Obesity treatment
• Weight loss support

Type 2 Diabetes

• Blood sugar control
• Improved A1C levels

Long-Term Weight Maintenance

• Helping patients maintain weight loss after initial success

Treatment Details

Administration

Most GLP-1 medications are:

• Once-weekly injections (Wegovy, Ozempic, Zepbound, Mounjaro)
• Daily injections (Saxenda)

Some newer oral versions are also available.

Treatment Plan

• Start with a low dose
• Gradually increase over several weeks or months
• Continue under medical supervision

This gradual increase helps reduce side effects.

• Improved metabolic health

Expected Results

Weight Loss Expectations

Results vary, but clinical studies have shown:

MedicationAverage Weight LossWegovy (Semaglutide)~15% of body weightZepbound (Tirzepatide)~20%+ of body weightSaxenda (Liraglutide)~5–10% of body weight

Individual results vary based on:

• Starting weight
• Diet
• Exercise
• Consistency with treatment
• Genetics and metabolism

Common Side Effects

What Is "Food Noise"?

One of the most commonly reported benefits is a reduction in food noise.

Many patients describe:

• Less constant thinking about food
• Reduced cravings
• Easier portion control
• Feeling satisfied after normal-sized meals

For many people, this is one of the most life-changing effects of GLP-1 therapy.
