Telemedicine appointments are available for patients across Florida, including the Tampa Bay Area, South Palm Beach, and North Broward.
Medical weight loss treats weight gain as a medical condition — not a character defect or a personal failure. That distinction matters because the interventions are completely different. A diet program addresses behavior. A medical weight loss program begins by identifying what is actually causing the weight gain, then treats that underlying cause.
Most people who struggle with their weight have already tried conventional approaches. The programs failed not because of poor willpower, but because a one-size-fits-all plan cannot account for the individual biological, hormonal, and metabolic factors that drive weight gain in each person. Dr. Rubin's approach starts where conventional weight loss ends — with a thorough functional medicine evaluation designed to find the cause before recommending any treatment.
Weight gain is almost never simply the result of poor diet and insufficient exercise. Before recommending any treatment, Dr. Rubin asks the questions most weight loss programs skip:
Understanding which of these — or which combination — applies to you is the key to a plan that works. The evaluation includes a review of your nutritional history, a full thyroid exam, a hormone panel, and a detailed look at what has and hasn't worked for you in the past.
After the evaluation, Dr. Rubin builds a personalized program drawing from the following, depending on your specific findings:
Dr. Rubin uses compounded GLP-1 medications — including semaglutide and tirzepatide — as part of medically supervised weight loss programs. These medications regulate appetite and insulin signaling, producing effective, sustained weight loss without extreme caloric restriction or invasive procedures. They can also be used safely in combination with other treatments in your plan.
Not all eating plans are appropriate for every patient. If undiagnosed Celiac disease or gluten sensitivity is contributing to your weight and health issues, a gluten-free protocol may be warranted. Others require different dietary frameworks entirely. Identifying the eating approach that matches your biology — not a generic meal plan — is central to lasting results.
If hormone imbalances are driving weight gain, Bioidentical Hormone Replacement Therapy (BHRT) may be incorporated into your plan. Hormonal contributors to weight gain — including thyroid dysfunction, low sex hormones, and adrenal imbalance — are evaluated and treated as medical conditions, not managed around.
For patients whose weight gain is tied to declining human growth hormone and the associated loss of lean muscle mass, Sarcotropin Therapy can be added to the program. Sarcotropin can also be used safely alongside semaglutide and tirzepatide.
Environmental toxins can disrupt metabolic function and contribute to weight gain that resists conventional treatment. Where warranted, a structured detox program is incorporated to remove compounds that may be suppressing your metabolism.
From gentle movement to high-intensity interval training, exercise recommendations are calibrated to your current fitness level, health status, and goals. Finding the right intensity for your body — not a generic protocol — makes the difference between sustainable progress and early burnout.
Dr. Rubin is ABIM Board Certified in Internal Medicine and Geriatrics Medicine and an Advanced Fellow in the American Academy of Anti-Aging Medicine. He spent the first 25 years of his career in internal and geriatric medicine, earning recognition from Castle Connolly Medical as one of the "Top Doctors" in South Florida for four consecutive years.
After completing a fellowship in anti-aging and regenerative medicine, he transitioned fully to functional medicine to better address the unmet needs of patients with chronic and complex conditions. Over the past 15 years, he has built a practice grounded in evidence-based care that takes the time conventional medicine rarely allows.
Free consultations are available at both clinics and via telemedicine for patients anywhere in Florida.
