A Physician-Supervised Program With Dr. Castelli
Our Medical Weight Loss Program is led by Dr. Joseph Castelli, who personally evaluates every patient and supervises every plan. This is medicine, not a subscription box: your program begins with a medical evaluation and continues with scheduled follow-ups, dose adjustments, and a physician who knows your history.
What Does The Program Include?
- A comprehensive medical evaluation and health history review
- Physician selection of the right GLP-1 medication for you — semaglutide or tirzepatide
- Structured dose titration and ongoing medical monitoring
- Nutrition and lifestyle guidance that makes results durable
- Optional body contouring with CoolSculpting as your shape changes
The GLP-1 Medications We Offer
Semaglutide (GLP-1) is a once-weekly injection that reduces appetite and helps you feel full sooner. Tirzepatide (GLP-1/GIP) adds a second hormone pathway for even greater average weight loss in clinical studies. Dr. Castelli will recommend the right medication — and the right pace — based on your health profile and goals. For background, see our semaglutide dosage guide.
Who Is A Candidate?
Adults who have struggled to lose weight with diet and exercise alone are often excellent candidates, particularly with a BMI in the ranges these medications were studied in. Some medical histories require extra caution, which is exactly why the program is physician-run — candidacy is a medical decision made with Dr. Castelli at your evaluation.

Medical Weight Loss FAQ’S
Is medical weight loss available in Bryn Mawr, PA?
Yes — the Medical Weight Loss Program at Lux Skin & Lasers in Bryn Mawr, PA is supervised by Dr. Joseph Castelli, serving patients across the Main Line and greater Philadelphia.
How much weight can I expect to lose?
Results vary by medication, dose, and adherence. In large clinical trials, patients on semaglutide averaged roughly 15% body-weight loss and patients on tirzepatide averaged roughly 20% at the highest doses, alongside lifestyle changes. Your physician will set realistic expectations for your plan.
Are GLP-1 medications safe?
They are FDA-approved medications with well-characterized side-effect profiles — most commonly temporary nausea or digestive upset during dose increases. Physician supervision exists precisely to screen candidacy, titrate doses gradually, and monitor your progress.
Do I need to follow a special diet?
No rigid diet is required, but the medications work best alongside protein-forward nutrition and regular activity. The program includes practical guidance so the weight you lose stays lost.
What happens when I reach my goal weight?
Dr. Castelli will discuss maintenance options — tapering, continuing at a maintenance dose, or transitioning fully to lifestyle maintenance — and can pair your new shape with body contouring like CoolSculpting if desired.
