The terms “insulin resistance” and “high blood sugar” are commonly heard, but what do they actually mean? Think of insulin as a key that unlocks cells to allow glucose inside, preventing elevated blood sugar levels. A diet consistently high in sugar, unhealthy fats, processed foods, and high in calories can prompt the pancreas to produce excess insulin. Over time, the pancreas may struggle to meet this demand, leading to insufficient insulin production and poor cellular response, which can result in Type 2 Diabetes.
Below are some expert recommendations and tips for maintaining balanced blood sugar levels.
Balance Your Macronutrients to Support Blood Sugar Stability
Macronutrients—carbohydrates, proteins, and fats—alongside micronutrients like vitamins, minerals, and phytonutrients, are the essential fuel sources for optimal body function. Proper intake of each macronutrient supports balanced blood sugar:
For a balanced approach, incorporate a variety of colorful fruits and vegetables, grass-fed or free-range animal protein and eggs, whole grains, legumes, and healthy fats like olive oil, nuts, seeds, and avocados. Prioritize lower-glycemic carbohydrates, such as leafy greens, fruits, whole grains, and vegetables, and limit refined carbs like white rice and bread.
Stay Hydrated
Water plays a vital role in nearly every bodily function, including circulation, digestion, nutrient absorption, and waste elimination. Adequate hydration also aids kidneys in flushing excess sugar from the blood through urine. While individual water needs vary depending on climate, activity, and diet, a general recommendation is 8-12 cups daily, sourced from both beverages and hydrating foods like fruits and vegetables.
Increase Fiber Intake
Dietary fiber is divided into soluble and insoluble forms, with soluble fiber—found in foods like beans, cruciferous vegetables, avocados, oats, and pears—offering the greatest benefit for blood sugar control. Together with fats and proteins, fiber slows carbohydrate digestion and absorption, helping to prevent blood sugar spikes. Aim for 35-50 grams of fiber per day, increasing gradually if new to fiber-rich foods to avoid abdominal discomfort. Easily digestible fiber supplements, such as acacia, may also be an option if dietary intake falls short.
Exercise Regularly
Engaging in regular exercise (3-4 times per week) can support a healthy weight, improve insulin sensitivity, and enhance glucose metabolism. Choose activities you enjoy and aim to increase heart rate for at least 30 minutes per session. A mix of strength training, stretching, and aerobic exercise contributes to optimal metabolic health.
Incorporate Foods High in Chromium and Magnesium
Micronutrients, particularly minerals like magnesium and chromium, are crucial for blood sugar balance. Chromium aids insulin function, helping cells absorb glucose. Without sufficient chromium, insulin efficacy diminishes, potentially leading to elevated blood sugar. Foods rich in chromium include meat, mussels, oysters, egg yolks, whole grains, green beans, and broccoli. Magnesium also supports glucose metabolism, and deficiencies may increase diabetes risk. Include magnesium-rich foods like tofu, nuts, seeds, and green leafy vegetables in your diet.
Did you know that chronic stress leads to magnesium loss? Elevated cortisol levels from chronic stress leads to higher magnesium excretion through the kidneys. Magnesium is filtered out by the kidneys and lost through urine, which reduces the body’s available magnesium reserves over time. In fact, some studies have shown that stress can significantly raise urinary magnesium excretion rates (1). So if you cannot meet your daily requirements through food, are on medication that depletes magnesium (I.E. Birth Control), or are chronically stressed, you might want to consider taking a supplement.
The Low Glycemic Diet: Why It Matters
Not all carbohydrates impact blood sugar the same way; some digest slowly, resulting in a lower glycemic response. The Glycemic Index (GI), developed by Dr. David Jenkins, ranks carbohydrate-containing foods by their effect on blood sugar levels:
Factors like cooking method and ripeness can influence GI ratings, but generally, choosing foods with low GI scores is recommended for blood sugar management. Foods with medium or high GI can be consumed in moderation, ideally paired with low-GI foods to stabilize blood sugar levels.
Some examples of low-GI foods include:
By adopting these guidelines, you can support balanced blood sugar levels, potentially reducing the risk of insulin resistance and Type 2 Diabetes.
Sunlight Exposure and Blood Sugar Regulation
Morning: Sunlight exposure, especially within the first hour of waking, is crucial for setting our circadian rhythm, which in turn affects improves the body’s regulation of blood glucose and insulin sensitivity throughout the day. Light exposure helps regulate the hormones and processes that influence glucose metabolism and insulin sensitivity (2). By getting consistent exposure to natural light at key times throughout the day—early morning, mid-morning, and near sunset—we can support blood sugar stability and overall metabolic health.
Mid-morning: Mid-morning sunlight exposure helps sustain the circadian rhythm set by morning light and supports glucose metabolism throughout the day. In fact, sunlight exposure later in the morning has been shown to reinforce insulin sensitivity and reduce glucose spikes, especially post-meal (3).
Midday sunlight: Midday sunlight exposure is essential for synthesizing vitamin D, a key nutrient for blood sugar regulation. Vitamin D is known to improve insulin sensitivity and helps the body utilize glucose more effectively (4). Low vitamin D levels are associated with an increased risk of insulin resistance and type 2 diabetes (5).
Sunset: Exposure to sunset light signals the brain to begin melatonin production, which is vital for restful sleep. Quality sleep is crucial for blood sugar control, as poor sleep disrupts insulin sensitivity and glucose regulation (6). Sunset exposure, therefore, promotes the release of melatonin in alignment with the circadian rhythm, supporting blood sugar stability through restful sleep.
Important Blood Sugar Balancing Tips
Important note:
Leaving cooked rice or other starches to cool at room temperature can encourage the growth of harmful bacteria, particularly Bacillus cereus, a bacterium commonly found in soil that can survive the cooking process. When rice or starchy foods are left out at room temperature, the warm environment allows these bacteria to multiply and produce toxins that can cause food poisoning (and even death), even if the food is later reheated. To prevent bacterial growth, it’s best to cool cooked rice and starches quickly by placing them in the refrigerator within two hours of cooking. This minimizes the time they spend in the “danger zone” (between 40°F and 140°F), where bacteria thrive.
Stress Management
Managing stress is crucial for blood sugar regulation and managing insulin resistance. Chronic stress triggers the release of cortisol and adrenaline, hormones that prepare the body for “fight or flight” by raising blood glucose levels to provide a quick energy source. Over time, persistently high cortisol levels can increase insulin resistance, as cells become less responsive to insulin due to the continuous demand for glucose regulation. This state not only raises blood sugar levels but also places extra strain on the pancreas, potentially accelerating the progression to Type 2 Diabetes (10).
Additionally, high cortisol levels can interfere with sleep quality, increase cravings for high-sugar, high-fat foods, and deplete essential nutrients like magnesium (as mentioned above), which plays a critical role in glucose regulation and insulin sensitivity. Stress management techniques, such as mindfulness, regular physical activity, and deep breathing exercises, can therefore help to reduce cortisol levels, improve insulin sensitivity, and support stable blood sugar levels. By incorporating stress-relieving practices into daily routines, you can significantly enhance overall metabolic health and lower the risk of insulin resistance.
Supplements to Support Blood Sugar Regulation
PGX – PGX (PolyGlycopleX) is a unique blend of plant fibers designed to support blood sugar balance by slowing the digestion of carbohydrates and reducing post-meal blood sugar spikes. By absorbing water and expanding in the stomach, PGX increases feelings of fullness and delays glucose absorption, helping stabilize blood sugar levels and reducing cravings. This effect can support overall glucose metabolism and insulin sensitivity when taken consistently as part of a balanced diet.
Gymnema – Gymnema supports blood sugar balance by helping to reduce glucose absorption in the intestines and enhancing insulin function, leading to more stable blood sugar levels. Known as the “sugar destroyer,” it may also help reduce sugar cravings by temporarily altering taste receptors, making sugary foods less appealing. These combined effects make Gymnema an effective natural option for managing glucose levels as part of a balanced lifestyle.
Berberine – Berberine is a powerful natural compound that supports blood sugar levels by improving insulin sensitivity and reducing glucose production in the liver. It activates an enzyme called AMP-activated protein kinase (AMPK), which plays a crucial role in glucose metabolism and fat regulation. Studies have shown that berberine can lead to significant reductions in fasting blood sugar and HbA1c levels, making it a beneficial supplement for those managing blood sugar imbalances (11).
R+Alpha-lipoic Acid – R+Alpha-lipoic acid is a potent antioxidant that supports blood sugar levels by enhancing insulin sensitivity and promoting glucose uptake in cells. It helps to reduce oxidative stress and inflammation, which are often linked to insulin resistance and metabolic disorders. Additionally, studies have shown that R+Alpha-lipoic acid can improve glycemic control in individuals with type 2 diabetes (12), making it a valuable supplement for maintaining healthy blood sugar levels.
Conclusion
Maintaining balanced blood sugar is essential for overall health and for reducing the risk of developing insulin resistance and Type 2 Diabetes. By focusing on a balanced diet with nutrient-dense, low glycemic foods, staying well-hydrated, incorporating regular exercise, and managing daily routines to support your circadian rhythm, you can promote stable blood sugar levels. Integrating sunlight exposure, mindful food choices, stress management techniques, and movement into daily habits contributes significantly to glucose metabolism, insulin sensitivity, and long-term metabolic health. Even small, consistent changes can lead to meaningful improvements in blood sugar control and well-being.
