✨ Last info session of 2025 = a night to remember! ✨

We were honored to have Taylor share her powerful weight-loss journey with our community. Like so many young moms, pregnancy weight stuck around no matter what she tried. She poured everything into her family—yet forgot to pour back into herself.

But here’s the truth: Moms are superheroes, and even superheroes need self-care and self-love. 💛

Taylor made the courageous decision to prioritize her health. And now? She’s more present, more active, and living the healthy lifestyle she wants to model for her kids. Her transformation is inspiring, and we couldn’t be more proud!

👏 Cheers to Taylor and every mom choosing themselves so they can show up even stronger for their families!

🔥 Tuesday Truths 🔥
Here’s what most people don’t know about weight-loss options…

Did you know GLP-1 medications are far less effective than bariatric surgery when it comes to achieving significant, long-lasting weight loss?

💊 GLP-1 Medications:
➡️ At best, 15–20% excess weight loss
➡️ Best suited for patients with a BMI of 34 and under
➡️ Insurance coverage for weight-loss use is under 30%

⚖️ Bariatric Surgery:
➡️ Achieves 60–80% excess weight loss
➡️ Recommended as the first-line option for BMI 35+
➡️ Insurance coverage is over 95%

Knowing the facts can help you make the best decision for your health, your goals, and your future.

Advanced Bariatrics

Led by two fellowship-trained weight loss surgery specialists, Dr. John Cheregi and Dr. Hsin-Yi Chang, Advanced Bariatrics was created to help people struggling with obesity confront their challenges and discover a happier, healthier way of living.
