The Diabetes Podcast®

Show Notes

Confused about which CGM is right for you? Amber (RD/LD, CDCES) and Richie compare the three major continuous glucose monitors in the U.S.: Dexcom G7, FreeStyle Libre 3 Plus, and the Eversense 365 implant. Topics: accuracy (MARD), warmup times, calibration mistakes, why "compression lows" aren't real lows, insurance vs. OTC pricing, and 5 questions to ask before panicking over a number. Plus: why the CGM isn't your judge — it's a tool, not a grade. You'll learn: ✅ Key differences between all 3 CGMs ✅ Why day-one readings are less reliable ✅ What causes false overnight lows ✅ Why cutting carbs can backfire on your graph ✅ How a post-meal walk shows up on your data

Part two of our three part diabetes tech series. Next up: Automated Insulin Delivery (AID) systems.

Diabetes advice seems to change every week, but the habits that work haven't changed in decades. Endocrinologist Dr. Karl Nadolsky of Docs Who Lift explains what actually moves the needle for Type 2 diabetes and prediabetes. In episode 79, Richie and Amber talk with Dr. Nadolsky, an endocrinology and obesity medicine specialist. They cover the simple diet and exercise habits that still work, why the fear of insulin is outdated, and how GLP-1s and SGLT2s fit in. They also cover rapid A1C drops, why diabetes educators matter, and how to avoid influencers selling a "secret." Ready to take control of your health? Download our FREE Type 2 and Prediabetes Remission Roadmap today at: https://roadmap.thediabetespodcast.com KEY TAKEAWAYS Energy deficit is the foundation. Mediterranean, low-carb, low-fat, fasting, and meal replacements can all work. Pick the one you can stick with. Consistency beats complexity. Daily walking plus a few weekly sets of strength training deliver the most benefit. Don't fear insulin. Proper treatment often avoids or reverses the need for it. If you do need it, it's a valid therapy. Fast A1C drops can backfire. Dropping blood sugar too quickly can worsen retinopathy and neuropathy, and you may feel awful for weeks.

Tired of checking every ingredient and still wondering what you can eat? We explore ultra-processed foods, type 2 diabetes, and why healthy eating does not have to mean making everything from scratch. Amber and Richie unpack two food studies, the 500-extra-calorie finding, and the gap between a useful food label and another rule that leaves you feeling like you failed. Ready to take control of your health? Download our FREE Type 2 and Prediabetes Remission Roadmap today at: https://roadmap.thediabetespodcast.com Key takeaways Processing and overall diet quality both deserve attention. The 2019 trial found higher average intake on its ultra-processed diet; it did not prove every packaged food causes overeating. Bread, yogurt, and frozen meals can have a place in a practical eating plan. Start with a useful change you can repeat, without blame or shame.

Did you know the American Diabetes Association's 2026 Standards of Care now name automated insulin delivery (AID) as the preferred method over multiple daily injections — even for adults with Type 2 diabetes? In this episode, Richie and Amber wrap up their three-part series on diabetes technology by tackling a question most people with Type 2 diabetes have never been asked: "If you need insulin today, why are you still doing it manually?" Amber breaks down: Why your pancreas does something injections simply cannot replicate The real evidence behind AID systems, including two major 2025 clinical trials on Type 2 diabetes How to use AID and still pursue Type 2 diabetes remission — because treatment today doesn't cancel out your outcome tomorrow What "manual mode" really means and how to prepare a backup plan Why a discrepancy between your CGM and finger-stick reading doesn't mean your technology is broken How insurance, cost, and the pharmacy-versus-durable-medical-equipment divide actually works If you're on multiple daily injections and your A1C isn't where you want it, this episode is for you. And if you're chasing remission, this episode is especially for you.
