Medical weight loss at Modern Endocrine in Oklahoma City goes beyond calories to address the hormonal and metabolic factors that can make weight loss feel impossible.

Led by dual board-certified endocrinologist Dr. Cassie Smith, our team tests before we treat… running 30+ biomarkers to find what’s actually driving your weight instead of guessing.

We don’t just hand you a meal plan… we look at how your whole body works together, paying special attention to insulin, thyroid, cortisol, sex hormones, and gut health, the systems that quietly control your metabolism.

Why can’t I lose weight, even when I’m doing the right things?

Often the problem isn’t effort… it’s biology. Insulin resistance, thyroid issues, high cortisol, shifting hormones in perimenopause, and gut imbalances can all make weight loss feel impossible, even when you’re eating well and exercising. Until those factors are properly tested and addressed, dieting harder usually doesn’t lead to lasting results. That’s why we start by identifying what’s driving stubborn weight.

Weight loss is complex, and there may be underlying factors affecting your progress that you don’t even realize are there. Instead of giving you another generic plan, we begin with lab testing to get a clearer picture of your hormones, metabolism, thyroid, and gut health. Once we understand what your body truly needs, we create a personalized plan that fits you and provide the accountability and support to help you achieve lasting results.

Our two-part approach to weight loss

We combine two things most programs treat separately: finding your root cause, and using GLP-1 medication the smart way.

Finding and fixing the root cause

We look at all the underlying hormonal and metabolic causes of weight gain, then build a plan for sustained results and better energy. Testing can include:

  • Thyroid
  • Insulin
  • Blood Sugar
  • Cortisol
  • Sex hormones &
  • Gut health…

the systems that control your metabolism. We treat what we find instead of telling you to simply eat less and move more.

Science-informed GLP-1 microdosing

GLP-1 medications can be a helpful tool for weight loss, but only if you’re the right candidate. When appropriate, we may use a personalized microdosing approach with smaller, carefully monitored doses tailored to your body, goals, and response. The goal is steady progress, fewer side effects, and better muscle protection with a strong focus on protein.

GLP-1s are never a stand-alone fix. They work best when paired with the habits that make results last: enough protein, strength training, quality sleep, daily sunlight, and regular movement.

What is GLP-1 microdosing?

GLP-1 microdosing means using a lower-than-standard dose under close medical supervision. It’s not right for everyone, but for the right patient, it can support sustainable weight loss with fewer side effects and better long-term consistency.

At Modern Endocrine, dosing is never one-size-fits-all. Your plan is guided by your labs, symptoms, goals, and progress, then adjusted case by case by our physician-led team.

Because the dose is lower and personalized, many patients tolerate treatment better and stay consistent… and consistency is what drives results. Microdosing isn’t a shortcut or a substitute for the fundamentals; it works alongside protein, strength training, sleep, and sunlight. Your provider monitors your progress and adjusts as you go.

Is this weight loss program right for you?

This program is built for people who’ve tried and stalled. It may be a fit if you recognize yourself here:

  • You eat well and exercise, but the weight won’t budge.
  • Your labs were called “normal,” but you know something’s off.
  • Weight crept up in perimenopause or menopause.
  • You suspect insulin resistance, thyroid, or hormones are involved.
  • You’ve lost weight before and regained it.
  • You have gut symptoms like bloating, gas, and/or acid reflux with weight gain
  • You want a doctor-led plan, not another fad diet.
