Separating Fact from Fiction: Debunking Common Myths About Diabetes

Diabetes is one of the most misunderstood health conditions out there, and it’s no wonder—there’s so much information floating around that it’s hard to know what’s true and what’s not. From “diabetes is caused by eating too much sugar” to “only overweight people get diabetes,” these common misconceptions can make managing or even understanding the condition a lot more challenging than it needs to be. In this post, we’ll debunk some of the most persistent myths about diabetes and provide clear, factual information to help you feel informed and empowered. Whether you’re living with diabetes, supporting someone who is, or just want to separate fact from fiction, this guide will help you make sense of it all.

Myth #1: Diabetes is caused by eating too much sugar.

Many of us have heard that eating too much sugar leads to diabetes, but it’s not that simple! Type 2 diabetes is actually the result of a unique combination of factors beyond just your sweet tooth. Sure, a diet high in sugar can lead to weight gain, which increases diabetes risk, but genetics and lifestyle habits play a far bigger role. If someone in your family has diabetes, your chances of developing it are higher, regardless of your sugar intake. Plus, things like lack of exercise, high-stress levels, and certain dietary habits can make the body less responsive to insulin—the hormone that helps manage blood sugar. So, while it’s wise to be mindful of sweets, preventing diabetes means focusing on a balanced lifestyle, not just avoiding sugar. It’s about nourishing your body with healthy choices, moving more, and finding a balance that works for you.

Myth #2: Only overweight individuals develop diabetes.

The myth that only people who are overweight develop diabetes can be misleading and even harmful. While it’s true that being overweight or obese does increase the risk of developing type 2 diabetes, it’s not the only factor that matters. Obesity contributes to diabetes because excess body fat, especially around the abdomen, can make the body less sensitive to insulin. Insulin is the hormone that helps cells take in glucose (sugar) from the bloodstream, using it for energy. When the body becomes less responsive to insulin—a condition called insulin resistance—the pancreas works overtime to produce more insulin to keep blood sugar levels in check. Over time, this extra strain can cause the pancreas to wear out, leading to high blood sugar levels and, eventually, type 2 diabetes.

However, research from the UK Prospective Diabetes Study (UKPDS), one of the most extensive studies on diabetes, shows that diabetes can develop in people of various body types. In fact, many people who are within a “normal” weight range, or who are only slightly overweight, are also diagnosed with diabetes. This is because other factors, like genetics, age, ethnicity, and lifestyle, also play critical roles. For example, if someone has a strong family history of diabetes, they may be more likely to develop the condition even if they’re not overweight. Additionally, certain ethnic groups are at a higher risk of developing diabetes due to genetic factors, regardless of body weight.

The UKPDS findings emphasize that diabetes is not solely about body size but also about how effectively the body uses insulin. People who may appear healthy by traditional standards might still have underlying risk factors, like a sedentary lifestyle or high levels of visceral fat—fat stored around internal organs—which can lead to insulin resistance. Similarly, stress, sleep quality, and dietary choices can all impact insulin sensitivity, further showing that diabetes is a complex condition influenced by many factors, not just weight.

Myth #3: People with diabetes must avoid carbohydrates entirely.

The belief that people with diabetes must completely avoid carbohydrates is a common misconception. Carbohydrates are, in fact, an essential part of a balanced diet for everyone, including people with diabetes.

According to the American Diabetes Association (ADA), the goal isn’t to eliminate carbs but to manage them wisely. Carbohydrates are the body's main source of energy, and when consumed thoughtfully, they can be part of a healthy meal plan that supports stable blood sugar levels.

The ADA recommends that people with diabetes focus on the quality and portion of carbohydrates rather than avoiding them entirely. This means choosing complex carbohydrates like whole grains, vegetables, and legumes, which digest more slowly and cause a gentler rise in blood sugar compared to simple carbs found in sugary snacks and refined grains. For people with diabetes, it’s essential to work with a healthcare provider or dietitian to determine the right balance of carbs, proteins, and fats, as everyone’s needs are different.

The ADA guidelines emphasize that a balanced, individualized carbohydrate intake can actually help people with diabetes better control their blood sugar levels. For example, pairing carbohydrates with fiber, protein, and healthy fats can slow down the absorption of glucose into the bloodstream, preventing large spikes and dips in blood sugar. The key is portion control and choosing nutrient-dense, high-fiber sources of carbs that provide steady energy throughout the day.
