Low testosterone after surgery? Here’s why it’s normal

Dr. Lindsey VanDyke — Wed, 17 Jun 2026 07:32:39 +0000

“Your body is essentially saying: I don’t have time for testosterone right now. I’m dealing with this. We’ll get back to that later.” I want to talk about a hormone pattern that gets people in trouble, usually because somebody saw a low number on a lab and reached for a prescription pad too fast. There […]

The 3-second rule: a walk that flattens your blood sugar

Dr. Lindsey VanDyke — Tue, 16 Jun 2026 07:28:45 +0000

“You eat, then you move. That’s the rule. No gym membership. No special clothes. Three seconds after your last bite, you get up.” I preach this rule in every diabetes consult I run. It’s the cheapest, most consistent blood-sugar intervention in medicine. And almost nobody is using it. It’s called the 3-second rule. What is […]

Why your “healthy” cereal spikes blood sugar more than a donut

Dr. Lindsey VanDyke — Mon, 15 Jun 2026 07:27:22 +0000

“One cup of raisin bran has the carbohydrate of three slices of bread. What the donut has that the cereal doesn’t is fat, and fat slows everything down.” I hear this all the time in the office. “Doc, I’ve changed my diet. I’m not eating donuts anymore. I’ve started eating a healthy breakfast. But I’m […]

What it’s actually like to live without a thyroid

Dr. Lindsey VanDyke — Sat, 13 Jun 2026 09:01:56 +0000

“I’m 20-some years out from losing my thyroid. Now I just feel like I’m in my 40s. That’s just how it is.” Patients want to know what it’s actually like to lose your thyroid. I get the question every week. I’m in a better position than most endocrinologists to answer it, because I had my […]

Bariatric surgery vs GLP-1: which one, when, and why

Dr. Lindsey VanDyke — Fri, 12 Jun 2026 08:54:48 +0000

“Surgery is a tool that travels with you. If your insurance changes, your job changes, your surgery is your surgery. You get to keep it.” GLP-1 medications have changed weight management. But they haven’t replaced bariatric surgery, and a lot of patients don’t know when one is the better tool, when the other is, and […]

Thyroid Nodules: What You Need to Know

Dr. Lindsey VanDyke — Fri, 24 Apr 2026 14:26:52 +0000

If your doctor just told you that you have a thyroid nodule, your first instinct might be to freak out. I get it. I’ve been there. I was diagnosed with thyroid cancer at 21 and I’ve been on full-dose replacement thyroid hormones ever since. But here’s what most people don’t know. Even some doctors don’t […]

What happens when you stop a GLP-1? The conversation every patient deserves

Dr. Lindsey VanDyke — Thu, 23 Apr 2026 14:26:06 +0000

Here’s a conversation I wish more people were having before they ever picked up their first GLP-1 pen. What happens when you stop? Not if. When. Because this is one of the most common questions I get in my office, and the honest answer is one most patients have never heard from the provider who […]

I ranked 6 popular yogurts by their carb-to-protein ratio. The results will change how you shop.

Dr. Lindsey VanDyke — Wed, 22 Apr 2026 14:24:40 +0000

Yogurt is one of the most aggressively marketed “healthy” foods in the grocery store. The packaging tells you it’s good for you. The aisle placement tells you it’s good for you. The brand name often has the word “light” or “fit” or “Greek” right there on the label. But some of these yogurts are functionally […]

Why We Don’t Take Insurance for Weight Loss

Dr. Lindsey VanDyke — Mon, 30 Mar 2026 09:08:57 +0000

And Why That’s Actually Better for Your Outcomes “Why don’t you take insurance for weight loss?” It’s a fair question—and an important one. Many people assume that if insurance doesn’t cover something, it must be optional or unnecessary. But in weight management, the opposite is often true. The insurance model isn’t built to support the […]

Why Direct Care Changes Everything About Your Endocrine Health

Dr. Lindsey VanDyke — Sun, 29 Mar 2026 09:00:17 +0000

Direct Care vs. Insurance-Based Clinics: What’s the Real Difference? One of the most common questions we get is: What’s the difference between being seen at Advanced Institute and going to a regular insurance-based clinic? And right behind it: Do you take my insurance? Both are fair questions. But the more important question is this: Is […]
