It is imperative to maintain healthy blood sugar levels in a fasted state, particularly when it comes to minimizing prediabetes and diabetes. Fasting blood sugar is the blood glucose levels after an overnight fast, usually 8-12 hours.
When this stage persistently elevated, it’s a sign of poor glucose metabolism or potential insulin resistance. Fortunately, there are better ways to keep fasting blood sugar levels more in balance through natural approaches.
In this article, we will review 6 scientifically proven strategies to naturally control fasting blood sugar and cover practical tips with real-life examples, as well as address common questions on the topic.
Prioritize a Low-Glycemic Diet: A Deeper Dive
Low-glycemic refers to foods that are digested slowly, releasing glucose in a gradual manner into the bloodstream…., which protects against spikes and crashes in blood sugar.
What is Glycemic Index (GI) and Glycemic Load (GL):
Glycemic Index (GI): How quickly a food raises blood glucose Foods are given a score between 0 and 100.
Low GI: 55 and below (e.g., lentils, chickpeas, quinoa)
Medium GI: 56–69 (e.g., sweet potatoes, brown rice)
High GI: 70 or higher (e.g., white bread, instant oatmeal)
Glycemic Load (GL): Takes into account the GI and the grams of carbohydrate in a serving. It is a more accurate representation of blood sugar response.
Benefits: Low-GI diets enhance insulin sensitivity, decrease inflammation, and contribute to long-term blood sugar balance. According to a study published in the American Journal of Clinical Nutrition, participants who were consuming a low-GI diet experienced improvements in fasting glucose and HbA1c levels (an indicator of long-term blood sugar control).
Low-GI Foods to Include:
Whole grains: Quinoa, oatmeal, barley Legumes: Chickpeas, lentils, black beans Vegetables: Spinach, carrots, and broccoli. Fruits: Berries, apples, oranges (in moderation).
Sample Meal Plan:
Breakfast: Steel-cut oatmeal with chia seeds and blueberries.
Lunch: Quinoa salad with grilled chicken and mixed vegetables.
Dinner: Baked salmon, steamed broccoli, sweet potato.
Snacks: Greek yogurt topped with walnuts, a small apple.
Pro Tip: Pair high-GI foods with protein or healthy fats to reduce their overall glycemic load.
Stay Physically Active: Types and Benefits
Exercising regularly is one of the best things you can do to regulate fasting blood sugar levels naturally. It improves insulin sensitivity and allows muscles to use glucose more effectively.
Types of Exercise:
Aerobic Activity: Such as walking, swimming, and cycling. Strive for at least 150 minutes of moderate aerobic exercise per week.
Resistance training Strength training is any kind of exercise that increases muscle mass, which is better at controlling glucose.
HIIT(High-Intensity Interval Training): Short bursts of high-intensity exercise followed by rest. HIIT has demonstrated better fasting blood glucose reductions compared to moderate-intensity exercise.
NEAT (Non-Exercise Activity Thermogenesis): Daily tasks such as gardening, cleaning, and walking. NEAT — non-exercise activity thermogenesis — can have a big impact on glucose control.
Why It Works: Exercise causes an increase in muscle glucose uptake independent of insulin. Based on the Journal of Diabetes Investigation, both aerobic and resistance training essentially reduced overnight blood sugar levels. Exercise also reduces weight, which is essential for insulin resistant individuals.
Real-Life Example: One 45-year-old with prediabetes introduced a regimen of walking and using resistance bands. His fasting blood sugar level had reduced from 120 mg/dL to 95 mg/dL after three months.
Tip of the Day: Pick an activity you like to stick with. Even vigorous walking for 30 minutes a day can have a significant effect.
Manage Stress Through Mindfulness and Yoga
Chronic stress elevates cortisol levels which can raise blood sugar. Proper stress management is crucial for maintaining normal fasting glucose levels.
How Stress Impacts Blood Sugar:
Under stress the body produces cortisol and adrenaline, instructing the liver to create more glucose for energy. This “fight or flight” mechanism can raise blood sugar, particularly in those with insulin resistance.
Mindfulness and Meditation:
Mindfulness practices — deep breathing, meditation and yoga — can also reduce cortisol levels. According to a Journal of Psychosomatic Research study, those who practiced mindfulness meditation had noted decreases in fasting blood glucose rates.
Simple Mindfulness Exercise:
Find a quiet space.
Close your eyes and breathe in slowly and deep.
Concentrate on your breath, inhaling up to four counts and exhaling for up to four counts.
Spend 10-15 minutes practicing daily.
Yoga for Blood Sugar Control:
Specific yoga postures, such as the “Child’s Pose” and “Bridge Pose,” stimulate the pancreas and regulate blood glucose. In a 12-week study published in Diabetes & Metabolic Syndrome, yoga reduced fasting blood glucose in people with type 2 diabetes significantly.
Pro Tip: Make time for at least 10 minutes of mindfulness or yoga every day, especially in stressful times.
Improve Your Sleep Quality: Optimize Your Circadian Rhythm
Sleep is critical to blood-sugar regulation. Poor sleep disrupts hormonal balance, leading to increased resistance to insulin and higher fasting blood glucose.
The Impact of Sleep on Blood Sugar Regulation: Deep sleep is when your body regulates hormones, including insulin. Disrupted sleep patterns can inhibit this process, leading to elevated glucose levels.
Circadian Rhythm and Blood Sugar: Your internal body clock or circadian rhythm helps you regulate sleep-wake cycles. Night shifts, irregular sleep, and misaligned circadian rhythms can increase insulin resistance risk.
Advice to Sleep Better
Keep a Routine: Sleep and wake at the same time every day. Make Your Sleep Environment Comfortable: Your bedroom should be cool, dark and quiet. Limit Screen-Free Time: No screens one hour before, one hour after (or at all, after 4 p.m.)Don’t Eat A Heavy Meal or Drink Caffeine Close to Bedtime: It’s harder to fall asleep when you’re digestive system is engaged.
Pro Tip: Practice some form of relaxation techniques, such as progressive muscle relaxation or calm music before bed.
5. Incorporate Natural Remedies: Beyond Cinnamon and Apple Cider Vinegar
Natural supplements may work alongside lifestyle changes to help regulate blood sugar.
Cinnamon: Cinnamon has compounds that increase insulin sensitivity. In the Journal of Medicinal Food, a meta-analysis showed that cinnamon consumption reduced fasting blood sugar levels by as much as 10 percent.
Apple Cider Vinegar (ACV):ACV slows carb digestion, lessening post-meal glucose spikes. Fasting blood glucose can also benefit from the consumption of one tablespoon of ACV diluted in water before meals.
Other Natural Remedies :
Fenugreek: High in soluble fiber that slows down the absorption of glucose. Berberine: This plant-based compound is found in goldenseal and improves insulin sensitivity while lowering fasting glucose. Turmeric: Antioxidant-rich curcumin, reduces inflammation while increasing the body’s insulin sensitivity.
A word of caution: Always check with a health care provider before taking supplements, especially if you’re on medication.
Stay Hydrated: Water’s Role in Glucose Regulation
Blood glucose concentrations can be elevated due to dehydration as there is less water in the plasma to dilute the glucose particles. Adequate fluid intake aids in excretory function of the kidneys to excrete excess glucose in urine.
How Much Water Do You Need?
Drink at least 8-10 glasses (2-2.5 liters) of water daily. Needs will depend on activity levels, climate and general health.
Signs of Dehydration:
Dark yellow urine
Fatigue
Dizziness
Dry mouth
Pro Tip: Bring along a reusable water bottle and set reminders to drink throughout the day. Steer clear of sugary drinks, which can send blood sugar soaring.
FAQs
What it is Fasting blood sugar and why it matters?
The fasting blood sugar is a test that measures your blood glucose level after you’ve gone 8–12 hours without eating. It shows how well the body handles its glucose. Elevated levels can indicate insulin resistance, prediabetes or diabetes.
How fast can these natural strategies reduce fasting blood sugar?
The results are variable, but often significant changes are noticeable in 4-8 weeks provided you work at it consistently. Progress accelerates with the combination of multiple strategies.
Are natural methods the substitute for medication?
Natural methods can help but should not replace medication without consulting a healthcare provider. Lifestyle changes might lessen or even eliminate the need for medication in the long term.
Does intermittent fasting do any good?
Yes, there is evidence that intermittent fasting enhances insulin sensitivity and reduces fasting blood sugar. But check with a health provider before beginning, particularly if you have diabetes.
What are the side effects when using natural remedies such as cinnamon or ACV?
Liver damage → cinnamon (due to coumarin) ACV can erode tooth enamel. The bottom line for natural remedies is always moderation and consultation with your doctor.
