What if lowering your blood sugar by removing carbohydrates isn't the same thing as actually reversing insulin resistance?
In this episode, Robby Barbaro takes a closer look at one of the biggest debates in diabetes nutrition: whether keto, carnivore, and low-carbohydrate diets actually address the underlying cause of insulin resistance—or simply lower blood glucose by removing the foods that reveal the problem.
You'll learn why a lower A1C is absolutely meaningful, but doesn't necessarily tell you whether your muscle and liver cells have become more sensitive to insulin.
Robby also breaks down research comparing ketogenic diets with low-fat, whole-food approaches and explains why weight loss can make the results of low-carb studies more complicated than they initially appear.
You'll also hear the remarkable story of T, who started with an A1C of 15.5 and was prescribed insulin before every meal plus once daily. Within three months, she was off insulin, her A1C fell to 7.8 and later reached 6.5—all while eating carbohydrate-rich whole foods like bananas, blueberries, and potatoes.
In this episode, you'll learn:
Why lowering blood sugar by restricting carbohydrates isn't necessarily the same as improving insulin sensitivity
Why A1C tells you how much glucose has been in your blood—but not necessarily why it went down
The important difference between clinical diabetes remission and restoring carbohydrate tolerance
How insulin resistance affects your muscles, liver, and fat tissue
Why excess fat inside muscle and liver cells can interfere with insulin signaling
How weight loss may explain some of the improvements seen on ketogenic diets
What happened when researchers tested ketogenic diets while keeping body weight stable
Why a quiet glucose meter on a very-low-carbohydrate diet doesn't automatically prove insulin resistance has been resolved
What the research on carnivore diets can—and cannot—tell us
Why saturated fat may have a different effect on insulin sensitivity than other types of dietary fat
What the Keto-Med Trial found when comparing a ketogenic diet with a Mediterranean-style, low-glycemic diet
How low-fat, whole-food, plant-based diets have been shown to reduce fat stored inside the liver and muscles
Why reducing intracellular fat can help improve insulin signaling
How people eating a low-fat plant-based diet consumed fewer calories naturally in a tightly controlled NIH study
How dietary fiber and the gut microbiome may contribute to better blood glucose control
How T went from an A1C of 15.5 and multiple daily insulin injections to eating fruit and potatoes without insulin
Why the ultimate question isn't simply how low your glucose is—but how effectively your body can process carbohydrate-rich whole foods
The goal isn't to build a smaller and smaller food cage just to keep your glucose meter quiet.
It's to improve the underlying insulin resistance so your body becomes better at processing the carbohydrate-rich whole foods it was designed to use.
By reducing dietary fat, keeping saturated fat low, eating fiber-rich whole plant foods, and reducing excess fat stored inside the liver and muscles, you can create an environment that supports greater insulin sensitivity and healthier glucose metabolism.
If you're following keto, carnivore, or a low-carbohydrate diet and wondering whether better blood sugar numbers mean your insulin resistance has actually improved, this episode will help you understand the important difference between controlling glucose and changing the underlying metabolic environment.
And remember: never change your diabetes medications on your own. Work with your healthcare provider, because medication needs can change quickly as blood glucose improves.
Keep your carbs high and your A1C low.

What if the key to improving type 2 diabetes isn't cutting carbohydrates—but giving your pancreas the conditions it needs to work more effectively?
In this episode, Robby Barbaro explains what's happening inside your pancreas, muscles, and liver when insulin resistance develops—and breaks down three practical shifts designed to improve insulin sensitivity and reduce the burden on your beta cells.
You'll also hear the remarkable story of Susan, who started with an A1C of 8.1 and, after six months of applying the Mastering Diabetes Method, reduced it to 4.9 while losing 29 pounds.
In this episode, you'll learn:
Why type 2 diabetes is fundamentally connected to insulin resistance—not simply high blood sugar
How excess fat inside muscle and liver cells can interfere with insulin signaling
Why lowering dietary fat can improve your body's ability to process carbohydrate-rich whole foods
Which fruits, vegetables, legumes, whole grains, and starches can form the foundation of an insulin-sensitizing diet

Why foods like potatoes, beans, rice, oats, and fruit don't need to be feared
How intermittent fasting may help reduce stored fat inside the liver and muscles
Why the dawn phenomenon can cause elevated fasting blood sugar even when you haven't eaten
How a 16:8 eating schedule can be used to support insulin sensitivity
Why eating earlier in the day may be more beneficial than eating late at night
How contracting muscles can take up glucose through an insulin-independent pathway
Why a simple 10–15 minute walk after meals can make a meaningful difference
How dietary changes, fasting, and movement work together to reduce the workload placed on your pancreas
How Susan reduced her A1C from 8.1 to 4.9
How Lenny reduced her A1C from 6.4 to 5.3 while losing 96 pounds
The goal isn't to fear carbohydrates or spend the rest of your life trying to manage blood sugar spikes.
It's to improve the underlying insulin resistance so your body becomes better at processing carbohydrate-rich whole foods.
By reducing dietary fat, creating periods of negative energy balance, and consistently activating your muscles, you can create an environment that supports greater insulin sensitivity and healthier glucose metabolism.
If you're struggling with elevated A1C, high fasting glucose, insulin resistance, or type 2 diabetes, this episode will help you understand what may be happening beneath the surface—and the lifestyle strategies you can start using to address it.
Keep your carbs high and your A1C low.

If you've been prescribed metformin, you deserve to understand exactly what it's doing inside your body.
In this episode, Robby Barbaro explains the science behind metformin, why it primarily lowers blood sugar by reducing glucose production from the liver, and why lowering blood sugar is not the same as reversing insulin resistance. You'll learn how metformin fits into diabetes care, what it can and cannot do, and why addressing the root cause of insulin resistance is essential for long-term health.
You'll also hear the latest research comparing metformin with intensive lifestyle intervention, learn why vitamin B12 monitoring matters for anyone taking metformin long term, and discover inspiring stories of people who dramatically improved their A1C through nutrition, movement, and medically supervised care.
In this episode, you'll learn:
How metformin lowers blood sugar by reducing glucose production in the liver
Why lowering blood sugar is different from reversing insulin resistance
The three root causes of insulin resistance and which one metformin actually addresses
Why fat inside your muscle and liver cells plays a central role in insulin resistance
What research says about metformin compared with intensive lifestyle intervention
Why lifestyle change was nearly twice as effective as metformin in the Diabetes Prevention Program
The importance of monitoring vitamin B12 levels during long-term metformin use
How walking for just 10 to 15 minutes after meals can significantly improve blood sugar
How Rhonda lowered her A1C from 10.9% to 5.5% while working with her healthcare team
How cardiologist Dr. Ace Yunis lowered his A1C from 10.8% to 5.9% and safely discontinued metformin under medical supervision
This episode isn't about choosing medication or lifestyle.
It's about understanding what metformin does, what it doesn't do, and why addressing the root cause of insulin resistance gives you the greatest opportunity to improve your health. Whether you're newly diagnosed or have been taking metformin for years, this episode will help you better understand your options and have more informed conversations with your healthcare team.
Keep your carbs high and your A1C low.
