The Prediabetes Wake-Up Call: Lifestyle Changes To Keep Diabetes at Bay

A prediabetes diagnosis can feel daunting, but many health experts describe it as an opportunity for positive change. The diagnosis indicates blood sugar levels are higher than normal but have not yet reached the diabetes range, which means the body is still highly responsive to healthful modifications.

According to the Centers for Disease Control and Prevention, more than two in five adult Americans are living with prediabetes, about 80 percent of whom are unaware of their condition. A landmark clinical trial showed that the Diabetes Prevention Program, involving lifestyle changes in diet and exercise, as well as modest weight loss, could effectively reduce the risk of developing Type 2 diabetes by 58 percent, outperforming medication alone.

 

Build a Balanced Plate

For many, the journey to diabetes prevention begins with dietary adjustments, not by restriction, as commonly thought, but by the adoption of better food pairings. Hillary Wright, a registered dietitian and director of nutrition at the Wellness Center at Boston IVF, in Massachusetts, recommends a “balanced plate” of one quarter lean protein such as seafood, poultry or tofu; one quarter fiber-rich carbohydrates like brown rice, quinoa or sweet potato; and the remaining half filled with colorful vegetables.

“Pairing carbohydrate-containing foods like rice or pasta with a source of lean protein increases the feeling of fullness a meal or snack provides and complicates the absorption of glucose into the blood, resulting in gentler blood glucose swings after meals,” she explains. The order of food consumption also plays a role, although Wright emphasizes the importance of making mealtime enjoyable rather than mechanical. While there is evidence that eating vegetables and protein before carbohydrates can be beneficial, the goal is to establish a sustainable habit rather than adhering to a rigid rule.

 

Read Food Labels Mindfully

Dr. Rebecca Hunton, medical director of Radiantly Healthy MD, a functional medicine clinic in Indialantic, Florida, developed a shortcut for evaluating packaged foods: subtract the grams of fiber, fat and protein from total carbohydrates. A result of 10 or less indicates a gentler effect on blood sugar and insulin levels, while higher numbers tend to cause spikes in both. “What I am really asking is whether the carbohydrate is arriving mostly by itself, or arriving buffered, slowed down by fiber, protein and fat,” she remarks, adding that finely milled whole grains often digest almost like flour, making the fiber count alone potentially misleading.

For protein quality, Hunton offers a second shortcut: multiply grams of protein by 10 and compare that number to total calories. If it matches or exceeds the calories, the food is relatively protein dense, a useful check when comparing yogurts, protein bars or prepared foods.

 

Consider the Whole Body

Prediabetes serves as a signal from the entire body, not merely an isolated blood sugar anomaly, both experts agree. Hunton notes that insulin resistance often develops before lab values shift, and unexplained weight gain is frequently the first clue. Hormonal changes, including those associated with perimenopause, can accelerate this transition. “Women frequently blame menopause for how they feel without realizing that what is happening is a cardiovascular and blood sugar change,” she says. Muscle mass also plays a pivotal role. Resistance training and regular physical activity, ranging from brisk walks to yard work, help the body regulate blood sugar levels.

 

Use Data as a Learning Tool

Wright holds mixed feelings about the use of continuous glucose monitors before a diabetes diagnosis, as there is insufficient evidence to define a normal pattern in prediabetes, and watching the data closely can inadvertently induce stress. “If wearing a monitor feels like it’s creating too much anxiety around eating, it’s a good indication to stop,” she advises. A more effective approach, she suggests, is to wear a monitor for just two to four weeks, supervised by a physician or registered dietitian that can help interpret the results.

Hunton uses monitors earlier and more frequently, turning nutrition from guesswork into personal data, and comparing the impact of meals, sleep and physical activity on the glucose curve. Still, she agrees with the underlying philosophy: the goal is to understand, not surveil or judge.

Both experts raise a similar caution regarding food tracking, acknowledging that while it can build awareness, it should be approached with caution or avoided altogether by individuals with a history of disordered[10]  eating, which is defined by the National Eating Disorders Association as “a spectrum of problematic eating behaviors and distorted attitudes towards food, weight, shape and appearance.”

 

Build Momentum With Modest Adjustments

According to Hunton, change does not have to be instantaneous to be meaningful. The body’s patterns take time to rewrite, and consistency matters more than speed. Patience coupled with practical tools like balanced plates, label reading, shortcuts and a willingness to observe personal patterns without judgment, is what makes prediabetes reversible for so many.

Anyone navigating a new prediabetes diagnosis is encouraged to work with a physician, registered dietitian or certified specialist in diabetes care and education because individual glucose responses vary. With the right support, prediabetes transforms from a cause for fear into a window to choose a different course of action.
