FAQ

Common Questions.

What does the program involve? +
Once you're approved, your program involves a simple weekly at-home routine that takes just a few minutes. Most patients find it easy and convenient. We walk you through everything at your first appointment and provide written instructions.
How is this different from working with my regular doctor? +
Defiant offers personalized management — custom plans, ongoing monitoring, and direct access to your provider. We also carefully vet every source we work with so you know exactly what you're getting and where it comes from. Quality and oversight first, every time.
Do you accept insurance? +
We operate outside of insurance by design. This allows us to spend real time with you, use the best available therapies, and focus on outcomes — not billing codes.
How quickly will I see results? +
Most patients notice appetite changes and early weight loss within the first 4 weeks. Significant results typically develop over 3–6 months of consistent treatment. Your provider will set realistic benchmarks based on your specific protocol and starting point.
Is the program safe? +
Our programs are administered under medical supervision through licensed providers. As with any medical care, there can be side effects — most commonly mild nausea or GI discomfort, particularly early on. Your provider will review your full medical history during your consultation.
