Part 1 of the Thrive Beyond 50 Diabetes Series
Over the next several blog posts, I’ll be taking a deep dive into one of the most important health challenges facing adults over the age of 50: diabetes. Rather than trying to squeeze an incredibly complex topic into a single article, I’ve created a 10-part series that will walk through the science in a practical, easy-to-understand way. We’ll discuss insulin resistance, Type 2 diabetes, nutrition, exercise, medications, prevention, and most importantly, what you can do to protect your health. My goal isn’t simply to explain diabetes, but rather to help you understand how it develops, why it matters, and how many people can dramatically change their future through simple, consistent lifestyle choices.
We begin with a condition that often receives far less attention than it deserves: prediabetes.
The word prediabetes can be misleading. It sounds like something that comes before the “real disease,” almost as though it isn’t particularly important. Unfortunately, nothing could be further from the truth. Prediabetes is the body’s early warning system. It tells us that blood sugar regulation is beginning to break down, even though most people feel completely normal. There is no pain, no obvious symptoms, and often no indication that anything is wrong. Yet beneath the surface, changes are already taking place that can eventually lead to Type 2 diabetes, heart disease, stroke, kidney disease, and other chronic illnesses.
That silent nature is exactly what makes prediabetes so dangerous. Millions of Americans are currently living with prediabetes, and many have no idea they have it. In fact, most individuals discover it only after routine blood work or during an annual physical. Because there are usually no warning signs, people continue living their normal lives while the condition quietly progresses. By the time symptoms such as excessive thirst, frequent urination, blurry vision, or unexplained fatigue begin to appear, diabetes may already be present.
One of the biggest misconceptions I hear is that prediabetes simply means “your sugar is a little high.” In reality, it represents a much larger story – the body is already struggling to keep blood glucose within a healthy range. The pancreas is working harder than it should, insulin levels are often elevated, and tissues throughout the body are becoming less responsive to insulin’s signals. These changes don’t happen overnight; instead, they usually develop gradually over many years.
Unlike many chronic diseases, prediabetes is frequently reversible. That’s an important word because people often assume that once blood sugar begins rising, diabetes is inevitable…however, the evidence tells a different story. Improvements in nutrition, increased physical activity, weight loss when appropriate, better sleep, stress management, and preserving or building muscle mass can dramatically improve how the body handles glucose. For many people, these changes are enough to return blood sugar to a healthy range and significantly reduce the likelihood of developing Type 2 diabetes.
As we age, this becomes even more important. After the age of 50, we naturally lose muscle mass if we don’t actively work to preserve it. Since muscle serves as one of the body’s primary storage sites for glucose, losing muscle means losing one of our greatest defenses against rising blood sugar. Add in a more sedentary lifestyle, gradual weight gain around the abdomen, poor sleep, chronic stress, and a diet high in ultra-processed foods, and it’s easy to understand why prediabetes has become so common.
The encouraging news is that none of these factors are set in stone. Every healthy meal, every walk after dinner, every resistance training workout, every pound of muscle gained, and every sugary drink replaced with water moves the body in a healthier direction. The goal isn’t perfection…it is to slowly tip the odds in your favor, one decision at a time. Small improvements performed consistently often produce far greater long-term results than dramatic changes that last only a few weeks.
Because prediabetes rarely causes symptoms, screening becomes extremely important, particularly for adults over 50. Healthcare providers often use a fasting blood glucose level, a hemoglobin A1c test, or in some cases an oral glucose tolerance test to identify individuals at increased risk. These simple laboratory tests can provide valuable insight long before diabetes develops, allowing time to intervene while the condition is still highly responsive to lifestyle changes.
Personally, I like to look a little deeper. Blood sugar tells us part of the story, but fasting insulin can sometimes reveal problems years before glucose levels begin to climb. Elevated fasting insulin often reflects the body’s attempt to compensate for increasing insulin resistance. While this isn’t part of routine screening for everyone, it can provide valuable information when viewed alongside traditional lab testing and an individual’s overall health picture.
One of the greatest mistakes we can make is waiting until diabetes develops before taking action. Think of prediabetes as the dashboard warning light in your car. Most of us wouldn’t ignore a flashing oil pressure light and continue driving for another year. We’d investigate the problem while it was still manageable. Prediabetes deserves the same respect. It isn’t something to fear, but it is absolutely something to address.
The good news is that your body has an incredible capacity to respond to healthy choices. Every day offers another opportunity to improve metabolic health. Even modest improvements can produce meaningful changes over time.
Dr. Edwards’ Take
One of the things I appreciate most about treating individuals with prediabetes is that there is genuine reason for optimism. Unlike many medical conditions that require increasingly aggressive treatment over time, prediabetes often responds remarkably well to lifestyle changes. I’ve seen people improve their lab values, lose weight, gain strength, increase their energy, and completely change the direction of their health by consistently making better choices. It doesn’t happen overnight, and it doesn’t require perfection. It requires persistence.
In the next article, we’ll explore what I believe is the true beginning of this entire process: insulin resistance. Long before blood sugar rises enough to be called prediabetes or diabetes, insulin resistance is quietly developing beneath the surface. Once you understand insulin resistance, you’ll begin to see why building muscle, eating whole foods, staying active, and maintaining a healthy weight have such a profound impact on your long-term health. In many ways, insulin resistance is the missing piece of the puzzle, and we’ll begin putting those pieces together in Part 2.
