Frequently Asked Weight Loss Questions
What sets a weight loss specialist doctor apart?
A medical weight loss doctor can evaluate a patient’s health, weight history, medications, and treatment goals before recommending an individualized plan. Treatment may include nutrition, physical activity, medical monitoring, and prescription weight-management medication when medically appropriate.
How can a weight management doctor in New Jersey help me?
A weight management doctor specializes in helping patients lose weight through medically supervised treatments. At his trusted weight management clinic in New Jersey, Dr. Robert Fortino brings years of clinical experience, innovative strategies, and a deep personal commitment to helping patients transform their health.
What makes Dr. Fortino the right medical weight loss doctor for my journey?
It’s not just about prescribing medications — it’s about delivering industry-leading care, tailored treatment plans, and real, lasting results. From GLP-1 weight loss medications to nutrition coaching and lifestyle support, every step is guided with expertise. When you work with an experienced weight management doctor, your journey is not only medically guided but also results-focused, with a team that truly cares about your success.
What is a Semaglutide weight loss injection?
Semaglutide is a GLP-1 receptor agonist used in several prescription medications. Wegovy, which contains semaglutide, is FDA-approved for chronic weight management in appropriate patients. Ozempic also contains semaglutide but has different FDA-approved indications. Dr. Fortino determines whether Semaglutide treatment may be appropriate following an individual medical evaluation.
Do I need a prescription for Semaglutide weight loss injections in Philadelphia, Pennsylvania?
Yes, Semaglutide weight loss injections in Philadelphia require a prescription from a licensed medical provider. At Dr. Fortino’s weight loss clinics in Philadelphia and New Jersey, Semaglutide is offered as part of a medically supervised weight loss program when medically appropriate.
What is Tirzepatide weight loss treatment?
Tirzepatide is a prescription medication that acts on GIP and GLP-1 receptors. Zepbound, which contains Tirzepatide, is FDA-approved for chronic weight management in appropriate patients. Mounjaro also contains Tirzepatide but is FDA-approved for different indications.
What is the difference between Tirzepatide and Semaglutide?
Tirzepatide and Semaglutide are different prescription medications. Semaglutide acts on the GLP-1 receptor, while Tirzepatide acts on both GIP and GLP-1 receptors. FDA-approved formulations, indications, dosing, potential benefits, risks, and side effects differ. The appropriate treatment depends on each patient’s medical history and individual needs.
Will insurance pay for Semaglutide or Tirzepatide weight loss treatment?
Insurance coverage for brand-name GLP-1 medications varies and typically requires patients to meet specific medical criteria, such as a qualifying BMI or related health condition. Some plans may require prior authorization. Because we offer compounded GLP-1 medications, insurance typically does not apply.
Can I get Phentermine appetite suppressant medication at your weight management clinic in New Jersey?
Phentermine is a prescription appetite suppressant that may be considered for appropriate patients as part of a medically supervised weight management plan. Dr. Fortino evaluates each patient’s medical history and health before determining whether Phentermine treatment is appropriate.
What is low testosterone therapy?
Low testosterone therapy, also known as Testosterone Replacement Therapy (TRT), iTestosterone Replacement Therapy (TRT) is a prescription treatment that may be considered for men with clinically confirmed testosterone deficiency. Evaluation typically includes symptoms, medical history, physical assessment, and appropriate laboratory testing.
How can I measure my body fat percentage and body composition?
At Dr. Fortino’s Philadelphia and Blackwood, New Jersey weight loss clinics, we use the seca mBCA Alpha medical body composition analyzer to look beyond BMI and the number on the scale. In just 24 seconds, this medically validated body composition analysis measures body fat, fat mass, skeletal muscle mass, visceral fat, and other important body composition markers.
Your body composition is measured during your initial new patient visit and can be monitored at follow-up appointments, allowing you and Dr. Fortino to see how your body is changing throughout your weight loss journey—not simply how many pounds you’ve lost.
Patients can also use the seca myAnalytics app on their phone to view their results, see changes in their body composition, and track their progress over time.
How do I get rid of belly fat?
Reducing belly fat—especially visceral fat, the deeper abdominal fat that surrounds your internal organs—usually requires more than simply doing abdominal exercises or following another restrictive diet. Visceral fat is influenced by overall weight, nutrition, physical activity, muscle mass, sleep, hormones, genetics, and metabolic health, including insulin resistance.
At Dr. Fortino’s Philadelphia and New Jersey weight loss clinics, we take a personalized, medically supervised approach to reducing excess body fat and improving overall health. Your plan may include nutrition, strength and physical activity, lifestyle changes, and weight loss medication when medically appropriate.
We also track visceral fat, body fat, and skeletal muscle mass with advanced body composition analysis, helping us look beyond the number on the scale and monitor meaningful changes throughout your weight loss journey.
