Nevin’s Story: Why We Built Thrive Rx
I'm Nevin Barley, co-founder of Thrive RX, not the doctor (that's my wife, Dr. Kiswani-Barley). I help fix what's broken in primary care, and I live the same root-cause approach we give every patient.
Nevin Barley, Co-Founder & Chief Operating Officer
"We built Thrive RX because we believe healthcare should feel different. You should feel heard. You should leave with a real plan. And the physician treating you should be genuinely focused on figuring out what's actually going on, not just what to prescribe to move on to the next patient."
Over the course of my career, I've been instrumental in helping organizations across many sectors improve their operations, processes, and policies. My greatest strength is working with subject matter experts to understand their work and find ways to improve existing workflows.
At Thrive Rx, I apply that continuous-improvement mindset to how we organize healthcare delivery, support patients, and build a practice that provides real value. All medical care is directed by Dr. Kiswani-Barley. My role is to build the operations and service around her expertise so patients can access high-quality care, feel supported, and work toward their best health. We're building an alternative to the frustrations of a traditional, high-volume, insurance-driven system: a practice where patients have time with their physician and care is designed around their needs.
You should feel heard
Not rushed out the door. Real conversations about what's actually going on with your health.
You should leave with a real plan
Not just a prescription. A clear, root-cause approach you can actually follow.
You should have direct access
The same physician every visit, one who listens, digs deeper, and advocates for you.
I Don't Just Run the Practice, I Live the Approach
The same root-cause, data-driven approach we use with patients is the one I've followed for my own metabolic health since February 2026, starting at 272 pounds. Here are my verified lab results. The after photo is coming soon.
Values from Nevin's lab reports: baseline collected October 2025 (fasting), follow-up May 11, 2026 (fasting), and July 1, 2026 (non-fasting, which makes the normal glucose and triglyceride results even more notable). Insulin was not measured at baseline. Cholesterol improvements reflect the full protocol, including a statin and fenofibrate added in May 2026.
Individual results vary and are not a guarantee of any specific outcome. Thrive RX does not diagnose or treat based on testimonial results. Every patient receives an individualized evaluation.
Before: 272 lbs
Late 2025, when Dr. Kiswani-Barley and Nevin decided it was time to get his health back on track.
Progress: Early June 2026, 233 lbs
Down 39 pounds, about two weeks after starting consistent resistance training.
After
Reveal loading… coming September 2026
From 272 lbs to 220, and Building a Stronger Body
52 pounds down and counting. Medication opened the door. Food, training, and accountability are what Nevin walked through it with.
October 2025
The wake-up call and a safety-first workup
Labs revealed Nevin was in real danger: triglycerides of 587, HbA1c in the prediabetes range, and a cholesterol/HDL ratio of 7.3, with a real risk of pancreatitis. Dr. Kiswani-Barley did a thorough workup first, including thyroid imaging because of a previous cyst, to make sure GLP-1 therapy would be safe before starting anything.
February 2026
Started Zepbound and changed the inputs
With the safety workup clear, Nevin started Zepbound and made the first big changes: no more processed foods, no more alcohol.
March 2026
Dose up to 5 mg, weight coming down
With better food choices sticking, the weight started moving. The Zepbound dose stepped up to 5 mg after the first month.
April – May 2026
7.5 mg, then 10 mg, down to 243 lbs
Nearly 30 pounds down. But the labs still weren't where they needed to be, and Nevin knew weight loss alone wasn't the finish line. He needed resistance training and tighter nutrition to preserve lean muscle and rebuild his metabolism.
May 11, 2026
Follow-up labs: progress, but not enough
Thirty pounds down and HbA1c back in the normal range, but the labs showed cholesterol still alarmingly high, with triglycerides at 512 and an insulin level of 51.6. Dr. Kiswani-Barley added a statin and fenofibrate to bring the triglycerides down. The message was clear: weight loss alone wasn't going to finish the job.
May 16, 2026
Getting started with resistance training
Nevin's first resistance-training session was humbling. Instead of quitting, he committed to a consistent routine. By May 22, resistance training had become a regular part of his plan, with a focus on building strength and preserving muscle alongside his medical care and nutrition changes.
Since then
Dramatic shifts in strength and conditioning
With nutrition properly dialed in, Nevin's conditioning, strength, and physique have started making dramatic shifts, building a body that's ready for lasting transformation.
Early July 2026
220 lbs, down 52 pounds
From 272 to 220 pounds while building visible muscle. The difference in the arms alone tells the story: this is what happens when medication, nutrition, and training work together.
July 2026
Chest and core definition, and the bloodwork catches up
On the way to 205 pounds, with chest and core definition starting to show. The July 1 labs tell the bigger story: insulin down from 51.6 to 11.3, HbA1c at 5.2, triglycerides normal for the first time on record, and testosterone up 40% from baseline, no TRT. The verified numbers are published below.
Dr. Kiswani-Barley's Take on This Transformation
"In October 2025, Nevin's labs told a dangerous story: triglycerides of 587, nearly four times the upper limit and high enough to carry real pancreatitis risk: an HbA1c in the prediabetes range, HDL of 34, and a cholesterol/HDL ratio of 7.3. Taken together, that's a pattern consistent with significant metabolic risk driven by insulin resistance."
"By May, the medication and nutrition changes had done real work: HbA1c was back in the normal range and roughly thirty pounds were gone. But the May labs also showed why weight loss alone is not the finish line: insulin was 51.6, triglycerides were still 512, and the LDL pattern was the small, dense, more atherogenic Pattern B. The engine was still running on insulin resistance."
"That's exactly why the training block mattered. Muscle is the largest site of glucose disposal in the body, the seven weeks of progressive training rebuilt the tissue that consumes glucose and restores insulin sensitivity. Insulin fell from 51.6 to 11.3. Triglycerides are normal for the first time in this record. And with no hormone therapy of any kind, testosterone climbed 40% as the body restored its own output. This is what happens when medication, nutrition, and training work together on the root cause, and the trajectory suggests the best numbers are still ahead."
