It signals your brain to reduce hunger, tells your pancreas to release insulin in response to glucose, and slows the emptying of your stomach to extend the feeling of fullness.</p> <p>GLP-1 medications mimic this hormone and amplify its effects. Originally developed to treat type 2 diabetes, these drugs unexpectedly produced substantial weight loss in clinical trials — which led to their development as dedicated weight loss treatments.</p> </div> <div class="ondra-section"> <h2>How GLP-1 medications produce weight loss</h2> <div class="ondra-info-card"> <p class="ondra-info-title">Appetite suppression</p> <p>GLP-1 receptors in the brain regulate hunger signals. Activation reduces overall appetite and the frequency of hunger sensations.</p> </div> <div class="ondra-info-card"> <p class="ondra-info-title">Reduced food noise</p> <p>Many patients describe a quieting of the constant background thoughts about food — sometimes called "food noise." This psychological shift is often described as transformative.</p> </div> <div class="ondra-info-card"> <p class="ondra-info-title">Slowed gastric emptying</p> <p>Food moves more slowly from the stomach into the small intestine, keeping you feeling full for longer after meals.</p> </div> <div class="ondra-info-card"> <p class="ondra-info-title">Improved insulin response</p> <p>GLP-1 medications improve how the body processes blood sugar, which has downstream effects on energy regulation and fat storage.</p> </div> </div> <div class="ondra-section"> <h2>GLP-1 medications currently available</h2> <div class="ondra-table-wrap"> <table class="ondra-table"> <thead> <tr> <th>Brand name</th> <th>Active ingredient</th> <th>Approved for</th> <th>Form</th> </tr> </thead> <tbody> <tr> <td>Wegovy</td> <td>Semaglutide</td> <td>Weight loss</td> <td>Weekly injection</td> </tr> <tr> <td>Ozempic</td> <td>Semaglutide</td> <td>Type 2 diabetes (off-label for weight)</td> <td>Weekly injection</td> </tr> <tr> <td>Rybelsus</td> <td>Semaglutide</td> <td>Type 2 diabetes</td> <td>Daily tablet</td> </tr> <tr> <td>Zepbound</td> <td>Tirzepatide</td> <td>Weight loss</td> <td>Weekly injection</td> </tr> <tr> <td>Mounjaro</td> <td>Tirzepatide</td> <td>Type 2 diabetes</td> <td>Weekly injection</td> </tr> <tr> <td>Saxenda</td> <td>Liraglutide</td> <td>Weight loss</td> <td>Daily injection</td> </tr> </tbody> </table> </div> </div> <div class="ondra-section"> <h2>Who may qualify for GLP-1 treatment</h2> <p>GLP-1 medications are typically considered for adults with a BMI of 30 or higher, or a BMI of 27 or higher alongside at least one weight-related health condition — such as type 2 diabetes, hypertension, high cholesterol, or sleep apnea.</p> <p>They are generally not appropriate for people with a personal or family history of medullary thyroid carcinoma or MEN 2 syndrome. Pregnancy is also a contraindication. A provider will review your complete health history before any prescription is issued.</p> </div> <div class="ondra-section"> <h2>GLP-1 alternatives to consider</h2> <p>If GLP-1 medications aren't right for you, other prescription options exist. Metformin has modest weight effects with a long safety record. Bupropion and naltrexone combinations can be effective for some patients. Your provider can review the full range of options based on your individual health profile.</p> </div> <p class="ondra-disclaimer"> † This article is for educational purposes only and does not constitute medical advice.
