Advent Weight Loss operates Medi-Weightloss clinics in Elk Grove Village and Algonquin, Illinois — bringing the nation's leading physician-supervised medical weight loss program to the Chicago suburbs. We are dedicated to helping our patients lose weight safely, protect their long-term health, and build sustainable habits that last.
As a franchisee of Medi-Weightloss, we deliver a nationally recognized, evidence-based program that has supported over 460,000 patients and helped them lose more than 10 million pounds across 130+ clinics nationwide. Our research has been published in Oxford's Journal of Public Health, and our clinical approach continues to evolve with the latest advances in medical weight loss — including GLP-1 medications like semaglutide and tirzepatide.
The weight loss landscape has changed dramatically. GLP-1 medications have made it easier than ever to lose weight — but easier doesn't mean safer. Patients across the country are losing weight through telehealth prescriptions and online pharmacies without the nutritional guidance and clinical oversight needed to do it right. The result is weight loss that comes at a cost: muscle loss, bone density reduction, nutritional deficiencies, metabolic disruption, and weight that comes right back.
We opened our clinics because we believe there's a better way. Medical weight loss should be truly medical — with real providers who know your name, personalized nutrition plans designed around your body, and a program structured to protect your health while the scale moves. That's what we deliver every day at our Elk Grove Village and Algonquin locations.
Medi-Weightloss is the nation's largest physician-supervised weight management program, with over 130 clinics across the United States. The program was founded in 2005 and has helped more than 460,000 patients achieve their weight loss goals through a structured, three-phase approach: acute weight loss, short-term maintenance, and long-term wellness.
As a Medi-Weightloss franchisee, we bring this proven program to the Chicagoland area with the added benefit of local ownership and a team that's invested in our community. Every patient who walks through our doors receives the same nationally recognized clinical protocols, enhanced by the personalized attention that comes from a team that genuinely cares about your success.
