Shut the Front Door Podcast

The host raises the question of whether Alzheimer’s is linked to insulin resistance, a growing area of research often dubbed “type 3 diabetes.” We break down insulin’s role in moving glucose into cells and explore what happens when the pancreas can’t keep up, leading to cellular energy deficits that may fuel cognitive decline. Emerging evidence increasingly points to metabolic dysfunction as a key factor in Alzheimer’s development.

This segment explores how rising fasting insulin levels can trigger widespread inflammation and impair thyroid function. While insulin is essential for moving glucose into cells, too much circulating insulin inflames tissues and hinders the conversion of inactive thyroid hormone into its active form. Over time, this imbalance may undermine metabolic health and contribute to ongoing wellness challenges.

In this short clip, the host talks about how people need to ask themselves, "what am I exposing myself too? The host gets you to think about how you can reduce these symptoms and how it has already affected other parts in your body.

In this clip, we break down how shifting to a carbohydrate-heavy diet raises blood sugar and triggers your pancreas to crank up insulin production. Think of insulin as a key and your muscles as the door where sugar is stored. When your blood sugar climbs, your body ramps up insulin output to lock that sugar into muscle cells and keep it out of your bloodstream.

This clip breaks down how muscle tissues gradually become less sensitive to insulin, forcing the body to produce more just to manage blood sugar. It explains that this reduced responsiveness is what we call insulin resistance—essentially the stage right before pre-diabetes.

In this clip, we explore why insulin resistance is often the early warning sign before pre-diabetes and how it fits into the larger spectrum of blood sugar health. The host explains that even when A1c and glucose levels are normal, a fasting insulin test can reveal rising insulin values. Understanding this “pre-pre-diabetes” phase can help you catch metabolic changes sooner.

In this clip, we explore why lowering insulin resistance should come before tweaking thyroid hormone levels. Because high insulin can counteract thyroid therapies, starting the process of reducing insulin resistance makes subsequent hormone corrections more effective. This step-by-step approach supports better metabolic balance and long-term health.

In this clip, we explore why stopping GLP-1 medications abruptly often triggers a fierce return of appetite and leads to weight rebound. You’ll learn the importance of tapering doses in a controlled, step-by-step way and why pairing that approach with sustainable lifestyle changes can help you maintain your progress.

In this clip, we explore why insulin resistance often returns first when tapering off GLP medications and how that rebound can lead to weight regain. We also discuss the rising prevalence of insulin resistance as a spectrum condition and its role as a precursor to diabetes.
