A Physician Dedicated to Medical Weight Loss Since 1999
Board-Certified Internal Medicine Physician | Doctor of Osteopathic Medicine (D.O.) | 30+ Years of Medical Experience | Obesity Medicine Association (OMA) Member | Lt. Col. & Flight Surgeon, 177th Fighter Wing, NJ Air National Guard
Medical Weight Loss | Metabolic Health | Men’s Health Specialist
Dr. Robert Fortino, D.O., is a board-certified internal medicine physician and medical weight loss doctor who has cared for patients throughout Philadelphia and South Jersey for nearly three decades.
A graduate of the Philadelphia College of Osteopathic Medicine (PCOM), Dr. Fortino has practiced medicine for more than 30 years and has focused on medical weight management since 1999—long before medical weight loss and today’s GLP-1 medications became part of mainstream healthcare.
His osteopathic medical training has also influenced the way he approaches patient care, emphasizing the importance of understanding the whole person and the many factors that can influence health.
Over the course of his career, Dr. Fortino has helped more than 100,000 weight loss patients, giving him a depth of experience that spans decades of change in physician-led medical weight loss, weight management, nutrition, metabolic health, medications, and preventive medicine.
Rather than building his practice around a single medication or treatment trend, his approach has evolved alongside advances in medicine while remaining grounded in individualized care and the doctor-patient relationship.
Dr. Fortino’s medical background extends beyond private practice. As a Lieutenant Colonel and Flight Surgeon with the 177th Fighter Wing of the New Jersey Air National Guard, his experience in military and aerospace medicine has reinforced the importance of physical readiness, prevention, strength, performance, and maintaining health over the long term. He is also a member of the Obesity Medicine Association (OMA) and continues to follow the evolving science of obesity, weight management, and metabolic health.
In 2026, Dr. Fortino and his team were named the Philly’s Favorite Gold Winner for Weight Loss Center by readers of The Philadelphia Inquirer, recognizing the practice among weight loss providers throughout the Greater Philadelphia region.
For Dr. Fortino, experience matters—but so does the relationship between a doctor and patient. He takes the time to understand each patient’s medical history, previous weight loss experiences, medications, nutrition, activity level, metabolic health, and personal goals. He believes patients deserve to be heard, understood, and cared for as individuals —because there is no single treatment plan that is right for every patient.
Not every patient comes to him simply to lose weight. Some want to better understand their metabolism, improve their energy and body composition, build strength, address changes that come with aging, or become more proactive about their health. Others want a more personalized approach that helps them manage their weight while improving their overall health, strength, and well-being.
Whatever brings a patient through the door, Dr. Fortino takes the time to understand the bigger picture of their health rather than automatically applying the same protocol to everyone. His goal is to provide thoughtful, individualized medical guidance in an environment that is personal, compassionate, supportive, and never judgmental.
“Medicine has changed tremendously over the past 30 years, but people haven’t. Patients still want a doctor who listens, knows them, and cares about what happens to them. That relationship has always been at the center of how I practice medicine.”— Robert Fortino, D.O.
Personalized, Physician-Supervised Medical Weight Loss
For nearly three decades, Dr. Fortino has provided physician-supervised medical weight loss to patients throughout Philadelphia and South Jersey. His approach combines medical expertise with the compassionate, supportive, and nonjudgmental care that has defined his practice for years.
Dr. Fortino understands that weight is personal and that many patients come to him after years of struggling to lose weight or maintain their results. His goal is to create an environment where patients feel comfortable discussing their concerns, asking questions, and getting the support they need without judgment.
There is no one-size-fits-all approach to medical weight loss. Every patient’s medical history, metabolism, lifestyle, previous weight loss experience, and goals are different—and every treatment plan should be too.
Depending on a patient’s individual needs and medical evaluation, treatment may include Semaglutide, Tirzepatide, Phentermine , personalized nutrition and lifestyle guidance, exercise recommendations, body composition analysis, laboratory testing, and ongoing medical follow-up.
For patients using GLP-1 medications, Dr. Fortino closely monitors their progress and provides personalized dosing, adjusting treatment based on each patient’s response, tolerability, progress, and individual medical needs.
Medication is only one part of the program. Dr. Fortino and his team provide ongoing education, encouragement, accountability, nutrition and exercise guidance, while helping patients work through challenges and make sustainable changes that support long-term weight management.
His approach focuses on helping patients:
- Reduce excess body fat while preserving lean muscle
- Improve metabolic health
- Develop healthier nutrition and exercise habits
- Better understand their body and treatment
- Feel supported, encouraged, and never judged
- Build healthy habits that can last a lifetime
For Dr. Fortino, successful weight loss isn’t simply about prescribing medication or lowering the number on the scale. It’s about building relationships, earning trust, and giving patients the medical care, education, support, and tools they need to become healthier, stronger, and more confident for the long term.
“The goal isn’t simply to help you lose weight. It’s to help you become healthier, stronger, and better equipped to maintain your results for life.” – Robert Fortino, DO
Men’s Health & Testosterone Replacement Therapy
With 30 years of experience in men’s health and testosterone treatment, Dr. Fortino brings extensive clinical experience to the evaluation and treatment of low testosterone in men and other health concerns that can affect overall health and well-being.
His background in internal medicine, men’s health, medical weight management, military medicine, nutrition, strength training, and physical fitness gives him a comprehensive perspective on the interconnected factors that can influence a man’s weight, metabolic health, body composition, strength, energy, hormone health, and overall well-being.
As an experienced men’s health physician serving Philadelphia and South Jersey, Dr. Fortino provides personalized care based on each patient’s medical history, symptoms, health concerns, laboratory findings, testosterone levels, and individual goals.
For men who are evaluated and diagnosed with testosterone deficiency, testosterone replacement therapy (TRT) may be an appropriate treatment option. Before recommending low testosterone treatment, Dr. Fortino evaluates each patient individually.
Patients receiving testosterone replacement therapy are monitored throughout treatment to assess their response, testosterone levels, laboratory values, symptoms, and overall health, with treatment adjusted when medically appropriate.
Dr. Fortino believes men’s health should be approached comprehensively, rather than focusing on a single symptom, testosterone level, or number on the scale. Weight, metabolic health, nutrition, physical activity, strength, body composition, hormone health, lifestyle, and overall wellness can all be important parts of the bigger picture.
With decades of experience caring for men, Dr. Fortino’s goal is to provide experienced, personalized, physician-led men’s health care that helps each patient better understand his health and develop an individualized treatment plan based on his medical needs and long-term goals.
“Men’s health is about more than a testosterone number. I look at the whole patient—their symptoms, medical history, metabolic health, weight, strength, lifestyle, and goals—before determining the right course of treatment.”— Robert Fortino,DO
The Inspiration Behind His Work
Dr. Fortino is a Board-Certified Internal Medicine physician and Doctor of Osteopathic Medicine (D.O.) whose approach to weight management grew directly from his experience treating patients with chronic health conditions.
Early in his medical career, Dr. Fortino provided home medical visits to underserved patients throughout Philadelphia and surrounding communities. Caring for patients in their own homes gave him a firsthand understanding of how nutrition, weight, physical activity, lifestyle, access to care, and other factors can influence a person’s overall health.
Over time, he became increasingly focused on obesity, metabolic health, and weight management as important components in the prevention and management of chronic conditions associated with excess weight, including Type 2 diabetes, insulin resistance, high blood pressure, high cholesterol, and cardiovascular disease.
Dr. Fortino’s approach goes beyond weight loss, focusing on metabolic health and the weight-related risk factors associated with Type 2 diabetes, high blood pressure, high cholesterol, and cardiovascular disease to support better long-term health.
Rather than focusing solely on treating individual numbers or symptoms, Dr. Fortino believes in looking at the whole patient—their medical history, metabolic health, nutrition, body composition, lifestyle, medications, and long-term health risks.
“I got into the weight loss arena because it’s a different way of approaching chronic issues like diabetes and high blood pressure. That’s the way you treat disease: at its roots.”- Robert Fortino, DO
That philosophy continues to shape his approach to physician-supervised medical weight loss and lifestyle medicine today. Nutrition plays an important role, with an emphasis on nutrient-dense foods, adequate protein, healthy fats, preserving lean muscle, physical activity, and sustainable eating habits rather than extreme diets or short-term fixes.
Dr. Fortino also emphasizes that obesity is a complex chronic disease—not simply a number on the scale or a lack of willpower. His goal is to help patients better understand the factors affecting their weight and metabolic health and give them the medical care, education, and tools they need to make meaningful, sustainable changes.
GLP-1 Medications & Medical Weight Loss
GLP-1 and related medications, including semaglutide and tirzepatide, may be appropriate treatment options for certain patients as part of a medically supervised weight loss program. These medications work through pathways involved in appetite, satiety, blood sugar regulation, and energy balance, which can help reduce hunger and make it easier for some patients to follow a healthier eating plan.
At Dr. Fortino’s Philadelphia and South Jersey weight loss centers, medication is one part of a comprehensive treatment plan, not the entire treatment plan. Each patient is medically evaluated based on their health history, current medications, weight-related health concerns, lifestyle, goals, and response to treatment.
Semaglutide and Tirzepatide are GLP-1–based medications that may be used as part of a physician-supervised weight management plan for eligible patients. These medications work through pathways involved in appetite, fullness, digestion, and blood sugar regulation, helping many patients feel satisfied with less food and experience fewer persistent thoughts about eating—often described as “food noise.”
For patients with overweight or obesity, GLP-1–based treatment may support meaningful weight loss and improvements in certain measures of metabolic health when combined with appropriate medical care, nutrition, physical activity, and lifestyle changes.
Both Semaglutide and Tirzepatide are administered through a once-weekly, subcutaneous injection at both the NJ and PA weight loss centers. Dr. Fortino carefully evaluates every aspect of a patient’s health, lifestyle, and medical history to determine the treatment plan.
“We are an overfed and undernourished nation addicted to processed food sugar” he says.
“This is a game-changer,” he says. “These medications allow patients to finally breakfree from the cycle of hunger and weight gain. Seeing my patients regain energy, improve their health and feel good about themselves again is incredibly rewarding.”-Robert Fortino, DO
A Comprehensive Approach to Health & Wellness
Dr. Fortino’s philosophy about nutrition and exercise didn’t begin with today’s weight loss medications—or even with his medical practice.
For more than 40 years, he has personally practiced strength training and powerlifting while studying the relationship between nutrition, body composition, strength, and metabolic health. Long before today’s focus on insulin resistance and metabolic health became mainstream, he was an advocate for a metabolic, insulin-conscious approach to nutrition built around nutrient-dense foods, adequate protein, healthy fats, and carefully selected carbohydrates.
That philosophy continues to influence how he educates his patients today.
A Metabolic Approach to Nutrition
Rather than focusing solely on calorie counting, restrictive diets, or highly processed “diet” foods, Dr. Fortino teaches patients to understand how the foods they eat can affect hunger, blood sugar, insulin response, body composition, and overall metabolic health.
His approach emphasizes:
- Adequate protein
- Nutrient-dense whole foods
- Healthy fats
- Fiber-rich foods
- Thoughtfully selected carbohydrates
- Reducing highly processed foods and added sugars
- Eating in a way that is satisfying and sustainable
“I teach my patients to focus on fueling their bodies with the right foods rather than obsessing over calorie numbers.” — Dr. Robert Fortino
As Dr. Fortino often explains, the goal isn’t to eat less forever. It’s to learn how to eat smarter for life.
Strong, Not Skinny
A longtime powerlifter and strength-training advocate, Dr. Fortino practices many of the same principles he encourages his patients to adopt.
His Strong, Not Skinny philosophy shifts the focus away from simply becoming lighter and toward preserving lean muscle, reducing excess body fat, building strength, staying active, and improving health and function as we age.
He believes the scale is only one measure of progress. Changes in body composition, strength, energy, mobility, metabolic health, and overall quality of life can tell a much more meaningful story.
Dr. Fortino’s practice also offers B12 Shot, MIC, L-Carnitine, Arginine, Taurine, Lysine, Glutathione, and other injectable vitamins, nutrients, and amino acids as optional components of individualized treatment and wellness plans.
“Our motto is ‘Strong, Not Skinny,’ because health isn’t about being thin—it’s about being strong, energetic, and feeling your best.” — Dr. Robert Fortino
For Dr. Fortino, this isn’t simply advice he gives his patients. It’s a philosophy of nutrition, strength, and healthy living that he has personally followed for more than four decades.
