The health check report is out: fasting blood glucose is 6.8 mmol/L—above the normal range. Or perhaps your postprandial blood glucose (2 hours after meals) is consistently high and irregular. Many people ask: “What should I do about high blood glucose?”
In fact, elevated blood glucose is a signal from the body. In most cases, through scientific dietary adjustments and exercise plans, blood glucose can be fully controlled within the ideal range. This article provides a practical 24-hour glucose-lowering plan from three dimensions: diet, exercise, and monitoring.
Part 1: First, Determine Your Blood Glucose Stage
Before making adjustments, understand which stage your blood glucose is in:
| Stage | Fasting Blood Glucose | 2-Hour Postprandial Blood Glucose | Recommendation |
|---|---|---|---|
| Normal | < 6.1 mmol/L | < 7.8 mmol/L | Maintain current lifestyle |
| Prediabetes | 6.1-7.0 mmol/L | 7.8-11.1 mmol/L | Intervene immediately, high chance of reversal |
| Diabetes | ≥ 7.0 mmol/L | ≥ 11.1 mmol/L | Systematic treatment + lifestyle management |
If fasting blood glucose is high, it usually indicates excessive liver glucose output, related to fatty liver and insulin resistance. If postprandial blood glucose is high, it is often linked to dietary structure and insufficient post-meal exercise.
Part 2: Glucose-Controlling Diet—How to Eat at Three Meals
Breakfast (7:00-8:00)
Breakfast is the starter for daily blood glucose. Avoid pure carbohydrate breakfasts (congee + steamed bun, bread + juice); these can trigger glucose fluctuations throughout the day.
- Recommended combination: 2 boiled eggs + 1 slice of whole wheat bread + 200ml unsweetened soy milk + a handful of nuts
- Avoid: Congee, sweet bread, sweetened yogurt, juice
- Principle: Protein first, carbs as supplement, dietary fiber mandatory
Lunch (12:00-13:00)
Lunch needs sufficient protein and dietary fiber to avoid post-meal drowsiness and blood glucose spikes.
- Recommended combination: 150g lean meat/fish + 200g green vegetables + half a bowl of mixed grains rice (brown rice/oats/quinoa)
- Eating order: Eat vegetables first → then meat/protein → finally the staple—this order can reduce postprandial blood glucose peaks by approximately 20%
- Avoid: White rice, fried foods, high-sugar condiments
Dinner (18:00-19:00)
Dinner should be "small and refined," finished 3 hours before bedtime to avoid nighttime glucose fluctuations.
- Recommended combination: 100g tofu/fish + mushroom and vegetable soup + a small amount of coarse grains (or no staple)
- Principle: Low calorie, high protein, easy to digest
💡 A simple tip: The 211 Plate Method
Divide your plate into 4 parts: 2 parts vegetables (50%), 1 part protein (25%), 1 part staple (25%). No matter what you eat, as long as the visual proportion is right, your blood glucose will be stable.
Part 3: What Exercise Lowers Blood Glucose the Fastest?
Exercise is the fastest way to lower blood glucose with the fewest side effects. However, different types of exercise affect blood glucose differently:
| Exercise Type | Glucose-Lowering Effect | Recommended Frequency | Notes |
|---|---|---|---|
| Aerobic Exercise (brisk walking/jogging/swimming) | Significant glucose reduction during and 1-2 hours after exercise | 5 times per week, 30 minutes each | Control heart rate at (220 - age) × 60-70% |
| Resistance Training (strength training) | Improves insulin sensitivity for 24-48 hours | 3-4 times per week | Start with bodyweight exercises, gradually increase load |
| High-Intensity Interval Training (HIIT) | Short and efficient, boosts metabolic rate | 2-3 times per week | Suitable for those with good cardiorespiratory function |
| Post-Meal Walking | Brisk walking for 15-20 minutes, 30 minutes after a meal, can reduce postprandial glucose peak by about 1-2 mmol/L | After every meal | The simplest and most practical way to lower glucose |
Dr. Sun Zhongwei's Three-Dimensional Reversal Theory particularly emphasizes the importance of resistance training. Skeletal muscle is the body's largest organ for glucose metabolism. Building muscle fundamentally improves insulin sensitivity, which is a "root-cause" approach to lowering blood glucose.
Part 4: Quick Reference Solutions for Different Blood Glucose Issues
What to Do About High Fasting Blood Glucose?
- Finish dinner before 19:00, no late-night snacks
- Reduce carbohydrate intake at dinner, increase protein and vegetables
- Persist with a 20-minute walk after dinner
- Improve sleep quality and manage stress (cortisol elevation stimulates liver glucose output)
What to Do About High Postprandial Blood Glucose?
- Adjust the eating order: vegetables → protein → staple
- Replace staple foods with low-GI coarse grains (oats, buckwheat, quinoa, brown rice)
- Control the amount of staple per meal, no more than one fist-sized portion
- Walk briskly for 15-20 minutes, 30 minutes after a meal
What to Do About Frequent Fluctuations (High and Low)?
- Establish a fixed three-meal schedule
- Maintain a balanced ratio of protein + vegetables + carbs in every meal
- Use blood glucose management tools to record and analyze glucose trends
- Avoid excessive exercise after binge eating
Part 5: Long-Term Lifestyle Habits for Glucose Control
- Sleep: Ensure 7-8 hours of quality sleep each night; staying up late significantly increases insulin resistance
- Hydration: Drink at least 1.5-2L of water daily; dehydration can increase blood glucose concentration
- Emotions: Chronic anxiety and stress raise cortisol levels, leading to increased blood glucose
⚠️ Note
If your random blood glucose consistently exceeds 13.9 mmol/L, or if you experience symptoms of diabetic ketoacidosis (nausea, vomiting, fruity-smelling breath), seek immediate medical attention. This article is for reference only and does not constitute a medical diagnosis.
