Physician-Led GLP-1 Weight Management
Personalized medication selection, nutrition support, body-composition monitoring and ongoing medical management for appropriate patients.
Physician-supervised GLP-1 weight management should begin with a medical evaluation, not simply a prescription request. At Weight Loss Clinic Los Angeles, Dr. David Nazarian evaluates the whole patient—including medical history, medications, metabolic health, nutrition, sleep, body composition and treatment goals—before recommending an individualized plan.

GLP-1 is a naturally occurring hormone involved in appetite, satiety and glucose regulation. Prescription medications that act on GLP-1 pathways may be used for chronic weight management in appropriately selected patients. Some medications act primarily on the GLP-1 receptor, while others act on more than one incretin pathway.
Medication is one tool within a broader medical weight-management program. Appropriate treatment also considers nutrition, physical activity, lean-mass preservation, sleep, side effects, medical conditions and long-term maintenance.
Dr. Nazarian is board certified in Internal Medicine and has extensive training in obesity medicine and medical weight management. His evidence-based, integrative approach considers potential contributors to weight difficulty such as medical conditions, medication effects, metabolic health, hormone or vitamin abnormalities when clinically relevant, sleep, nutrition and lifestyle.
Patients receive ongoing follow-up so response, tolerability, nutrition, hydration and other clinical factors can be monitored and treatment adjusted when appropriate.

Semaglutide is a GLP-1 receptor agonist. For appropriate patients, an FDA-approved semaglutide product may be considered according to its indication and prescribing information.

Tirzepatide acts on both GIP and GLP-1 receptors. It may be considered for eligible patients after evaluation of indications, contraindications, prior treatment, side effects and individual goals.

Eligibility for prescription weight-management treatment depends on factors including BMI, weight-related medical conditions, medical history, current medications, contraindications, pregnancy status and individualized risk-benefit assessment. Not every patient needs or should use a GLP-1 medication.
GLP-1-based medications can cause adverse effects and may not be appropriate for everyone. Follow-up can address effectiveness, gastrointestinal symptoms, hydration, nutrition, medication interactions, changes in glucose or blood pressure when relevant, and symptoms requiring additional evaluation.
Meaningful weight loss can include loss of lean tissue as well as body fat. Our approach emphasizes adequate nutrition, protein intake, resistance exercise when medically appropriate and body-composition monitoring when useful.

FDA-approved medications have undergone FDA review for safety, effectiveness and quality for their approved uses. Compounded medications are not FDA approved. When compounding is clinically relevant, patients should understand the differences, limitations and current regulatory requirements, and treatment should be based on an individualized medical need.
There is no single best medication for every patient. Selection depends on medical history, indications, contraindications, treatment response, side effects, availability and goals.
No. Semaglutide primarily targets the GLP-1 receptor, while tirzepatide targets both GIP and GLP-1 receptors.
Yes. Medication does not replace nutrition, physical activity, sleep and long-term behavioral strategies. These remain important for health, body composition and maintenance.

Cost depends on the specific medication, insurance coverage, pharmacy, dose, and whether treatment is part of a physician-guided program. Our current Semaglutide program is $300 per month and our Tirzepatide program is $499 per month; the initial comprehensive physician evaluation is separate.
Not every patient needs the same testing. Laboratory evaluation may be recommended based on medical history, symptoms, current medications, and clinical risk factors.
Duration varies. Chronic weight-management treatment should be reassessed over time based on benefit, side effects, health changes, goals, and maintenance planning rather than using a fixed treatment duration for everyone.
Sometimes, but medication changes require medical review because dose equivalence, side effects, timing, and contraindications differ. See our Semaglutide and Tirzepatide pages for more detail.
