Tirzepatide Weight Loss Program: $499 per month

Tirzepatide Weight Loss Program: $499 per month
Initial comprehensive physician evaluation is separate. Medication eligibility, laboratory testing, and ongoing recommendations are individualized.
Tirzepatide is a once-weekly medication that activates both GIP and GLP-1 receptors.
These hormone pathways can influence appetite, fullness, food intake, glucose regulation, and metabolic health.
For medically appropriate patients, tirzepatide may support meaningful weight reduction when combined with physician supervision, appropriate nutrition, physical activity, and long-term lifestyle changes.
At our Los Angeles weight loss clinic, treatment is not based on medication alone.
We evaluate your medical history, medications, weight history, metabolic health, nutrition, body composition, activity level, and long-term goals before recommending treatment.
$499 per month
Physician-guided medical weight management for eligible patients.
Your treatment program may include:
Medical eligibility is required.
The initial comprehensive physician evaluation is separate from monthly program pricing.
Medication, laboratory testing, or additional services may involve additional costs depending on the individual treatment plan.
Tirzepatide affects hormone pathways involved in appetite regulation and may help some patients experience less hunger.
Patients may feel satisfied with smaller portions, which can make reducing overall calorie intake easier.
Some patients report reduced food cravings or less preoccupation with food during treatment.
Tirzepatide also affects pathways involved in glucose regulation and metabolic function.
Medication is incorporated into a comprehensive medical program that also considers nutrition, physical activity, metabolic health, sleep, stress, and long-term weight maintenance.

Tirzepatide is not appropriate for every patient.
Eligibility depends on your BMI, weight-related medical conditions, medical history, medications, previous treatments, and other individual health factors.
Potential candidates may include:
A physician consultation is required to determine whether tirzepatide or another weight-management option may be appropriate for you.
We review current and previous medical conditions, medications, allergies, symptoms, weight history, and previous weight-loss treatments.
Weight is evaluated alongside body composition and other clinical factors rather than relying only on the number on the scale.
Laboratory studies may be recommended when medically appropriate to evaluate metabolic, hormonal, or other health factors that could influence treatment.
Your physician develops an individualized strategy that may incorporate medication, nutrition, physical activity, supplements, body-composition monitoring, and other medical recommendations.
Treatment is overseen by Dr. David Nazarian, a board-certified internal medicine physician with extensive experience evaluating metabolic health, weight-management medications, nutrition, supplements, and other factors that may contribute to a patient’s ability to lose weight.
Rather than simply prescribing medication, treatment recommendations are individualized according to medical history, metabolic risk factors, current medications, treatment response, tolerability, body composition, and long-term health goals.
Tirzepatide and semaglutide are both used in modern medical weight management, but they work through different hormone pathways. Tirzepatide activates GIP and GLP-1 receptors, while semaglutide activates the GLP-1 receptor. There is no single medication that is best for every patient; selection depends on medical history, treatment goals, previous response, tolerability, cost, availability, and physician assessment.

Successful medical weight management should focus on improving body composition, not simply reducing scale weight. Our approach may include adequate protein intake, resistance exercise when medically appropriate, nutrition counseling, body-composition monitoring, and adjustments to calorie intake when necessary.

Like all prescription medications, tirzepatide has potential side effects, risks, and contraindications. Commonly reported gastrointestinal effects can include nausea, reduced appetite, diarrhea, constipation, abdominal discomfort, and vomiting. Appropriate dose escalation and ongoing medical monitoring can be important for managing treatment safely. Your physician should review your complete medical history, medications, and individual risk factors before prescribing treatment.
Weight regulation is complex. Medication is only one component of successful long-term weight management. Our physician-guided approach may also evaluate nutrition and calorie intake, protein intake, exercise and resistance training, sleep quality, stress, metabolic health, existing medications, hormonal or laboratory abnormalities when clinically relevant, body composition, weight-loss plateaus, muscle preservation, and long-term maintenance.

Tirzepatide activates GIP and GLP-1 receptors, which can influence appetite, fullness, food intake, and glucose regulation. For appropriate patients, this can support weight reduction as part of a medically supervised program.
Some patients notice changes in appetite relatively early in treatment, while weight reduction generally develops progressively over time. Individual response varies.
Results vary according to starting weight, medication response, dose, treatment duration, nutrition, physical activity, underlying health conditions, and individual biology.
Neither medication is universally best for every patient. Treatment selection should be individualized according to medical history, previous treatment, goals, tolerability, cost, and physician assessment.
Laboratory testing may be recommended depending on your medical history, medications, symptoms, metabolic risk factors, and individual health considerations.
Weight regain can occur after discontinuing weight-management medication. Long-term nutrition, exercise, muscle preservation, and maintenance planning are therefore important components of treatment.
