Lake Mary is one of Central Florida’s most sought-after communities, known for top-rated Seminole County schools, a low crime rate, and a family-friendly atmosphere. With a daytime population that nearly doubles to over 35,000, this area is home to busy professionals commuting to Orlando, Sanford, and Altamonte Springs — people who need a weight loss program that respects their time while delivering measurable results.
Many of our Lake Mary patients are young professionals and families who have tried boutique fitness studios, personal trainers, and meal delivery services but still struggle with stubborn weight that won’t budge without medical intervention. Our physician-guided approach goes beyond diet and exercise to address hormonal, metabolic, and lifestyle factors — with GLP-1 medications, vitamin B12 shots, and customized nutrition plans built around your family’s preferences.
Powerful prescription options available at our Lake Mary clinic that help reduce appetite and support consistent, medically supervised weight loss.
Nutrition guidance that fits real life—no starvation plans, crash diets, or impossible rules.
Simple weekly check-ins to track progress, stay motivated, and adjust your plan as you go.
Your plan is customized to your goals, lifestyle, and response because what works for one person may not work for another.
Optional wellness injections, such as B12/MIC and Glutathione, along with custom supplements help to support energy, metabolism, and overall well-being while you lose fat and maintain muscle.
Aftercare options designed to help you maintain your results long-term—not rebound after the program ends.

Nuviva’s Lake Mary weight loss clinic on Rodel Cove is a medically supervised practice offering personalized programs that may include GLP-1 medications and other advanced prescription therapies.
Unlike commercial diet centers in the Lake Mary area, we combine physician oversight, structured nutrition coaching, and weekly accountability to support steady fat loss and long-term success — not short-term dieting. Our Lake Mary team understands the health priorities of Seminole County professionals and families, including busy commuters who need a program that respects their time.
Yes. Nuviva offers GLP-1 medications and other modern injectable weight loss options when clinically appropriate.
GLP-1 therapies work by helping regulate appetite, improve fullness, and support consistent fat loss. Your provider will evaluate your medical history and goals to determine whether a GLP-1 medication is appropriate for you.
GLP-1 medications work with your body’s natural appetite-regulating hormones.
They may:
When combined with structured coaching and nutrition guidance, GLP-1 therapies can significantly improve consistency and long-term results.
Yes. Many clients find that GLP-1 medications reduce both physical hunger and food-related urges.
Cravings are often hormone-driven—not simply a lack of willpower. GLP-1 therapies help regulate those signals, making it easier to stay aligned with your nutrition plan.
In most cases, no. By utilizing the most appropriate solution from our comprehensive resources, most people do not experience hunger related issues. We will work with you to choose the most fitting and medically appropriate option from our medication and supplement resources to include cutting-edge medications, such as GLPs, traditional prescription appetite suppressants and customized supplements to aid with hunger relief, we are confident you’ll find the right medications and tools for your weight loss journey.
GLP-1 medications have been widely studied and are commonly prescribed under medical supervision.
At Nuviva, your eligibility is determined by a medical provider based on your health history and risk factors. Dosing is introduced responsibly and adjusted as needed to support safe, steady progress.
No. While GLP-1 medications support appetite regulation, long-term success still requires proper nutrition habits.
We do not believe in crash dieting. Your nutrition strategy is designed to fit your lifestyle while supporting fat loss, metabolic health, and long-term sustainability.

Regular check-ins help us:
Virtual visits are also available for Lake Mary-area patients who need added flexibility.
Yes. Ongoing coaching is a core component of our comprehensive weight loss programs.
Medication alone is not the solution. Coaching ensures you build habits that protect your results long term.
No. Nuviva operates on a week-to-week basis.
You are never locked into a long-term contract. Clients continue because they are seeing results—not because they are obligated.
Results vary, but many clients experience steady, meaningful fat loss when they follow their program consistently.
Our focus is not rapid, unsustainable weight loss—but progress you can maintain. Since 2007, we have helped over 100,000 clients reach their goals.
