“The FIT50 Program is the ‘missing link’ that I was looking for. It is not a program where you are told not to eat ‘this’ or ‘that.’

It educates you and gives you the tools so that you know exactly what happens to your body and gives you the freedom to make your own choices.”

Linda Gray

Golden Globe Award Nominated Actress

"I’m a former professional athlete and two-time Super Bowl Champion. I know what it takes for my body to perform at its optimal potential. Implementing the FIT50 program into my life has helped me achieve that goal.

My energy has increased, my metabolism is better, and I don’t remember the last time I got a cold."

FAQs

What Are GLP-1 Medications?

GLP-1 medications are a class of prescription drugs that not only improves blood sugar control but may also lead to weight loss. This class of drugs is commonly called glucagon-like peptide 1 (GLP-1) agonists. Weight loss can vary, depending on which GLP-1 drug you use and the dosage.

Some of the more common side effects include:

Nausea, Vomiting, Diarrhea.

Side effects can often be mitigated by correctly titrating your dosage upward, so you’ll want to ensure that you are taking the medication exactly as prescribed by your provider to minimize risk and/or severity of side effects. Anti-nausea medications such as ondansetron (generic Zofran) are also helpful to assist in mitigating nausea.

Low blood sugar levels (hypoglycemia) are a more serious risk linked to the GLP-1 class of drugs. But the risk of low blood sugar levels often only goes up if you’re also taking another drug known to lower blood sugar at the same time, such as sulfonylureas or insulin. The GLP-1 class of drugs isn’t recommended if you have a personal or family history of medullary thyroid cancer or multiple endocrine neoplasia. Lab studies have linked these drugs with thyroid tumors in rats. But until more long-term studies are done, the risk to humans isn’t known. The GLP-1 class of drugs is also not recommended if you’ve had pancreatitis.

Is the program safe?

Yes. Every plan is medically supervised and tailored to your health profile, goals, and individual needs to ensure a safe and appropriate approach.

What should I do if I miss a dosage?

If you miss a dosage on your day of the week, please reach out to us before continuing your dosage. You may need to lessen your dosage for your next dose in order to minimize risk and/or severity of potential side effects.

How is this different from dieting on my own?

Most people are left relying on guesswork, conflicting advice, or generic plans. A medically guided approach provides structure, personalization, and ongoing support designed for more sustainable results.

What happens during the consultation?

We’ll discuss your goals, health history, and previous experiences with weight loss to better understand the right path forward — with no pressure or obligation.

Are results guaranteed?

No. Results vary by patient. Your progress depends on your health profile, consistency, treatment plan, and ongoing follow-through.

Can I take a dosage that I've already been on if I'm switching to you from another doctor?

Please discuss your previous prescription and dosage with your provider during your medical intake process when enrolling and if medically appropriate, your provider will coordinate your dosage accordingly.
