Summary of Key Points
This article focuses on "metabolic health" and reveals that insulin resistance is the common underlying cause of metabolic problems such as fatty liver, high uric acid levels, and menstrual irregularities. Long-term poor dietary habits (such as consuming refined carbohydrates and processed foods) and unhealthy lifestyles are the main culprits. The article uses real-life examples to illustrate the specific manifestations of metabolic imbalance and explains the four key metabolic pathways affected by insulin resistance, as well as the signs to look for on your own body. It concludes with the "Balancing Blood Sugar Metabolism Method"—which involves consuming foods with a low GI (Glycemic Index), low II (Insulin Index), and anti-inflammatory properties, combined with a scientific eating order—to help individuals restore their metabolism. The method emphasizes that the approach to managing blood sugar needs to be personalized, as everyone's metabolism is unique.
The Hidden Culprit Behind Metabolic Imbalance: Where Does Insulin Resistance Come From?
Insulin acts like a "transporter" for glucose in the body; carbohydrates we eat are converted into glucose, and insulin is responsible for delivering this glucose to cells to provide energy. However, if you consistently consume high-GI foods like white rice and steamed buns, or frequently eat processed meals and sugary drinks (which contain many additives), your pancreas has to work overtime:
- High-GI foods cause blood sugar to spike rapidly, leading to excessive insulin secretion.
- Additives and preservatives in processed foods can directly damage pancreatic cells.
- Extreme dieting (such as the popular fat-loss diets) can disrupt the endocrine system, causing insulin signaling to become chaotic.
Over time, insulin becomes less effective (insulin resistance occurs), and glucose accumulates in the bloodstream, leading to a range of issues such as fatty liver, high uric acid levels, and increased blood pressure. Examples like Xiao Zhu (who frequently eats out and avoids vegetables) and Chen Lin (who follows extreme dieting routines) demonstrate how these bad habits can cause comprehensive metabolic problems.
The Four Metabolic Pathways: Warning Signs from Your Body
Insulin resistance is not a isolated issue; it affects four major pathways in the body, each with distinct physical symptoms that can help you identify potential problems:
1. Pancreas-Glucose Pathway: The pancreas becomes overworked.
Symptoms: Itching skin, blurred vision, slow wound healing, and extreme hunger before meals. → May lead to high blood sugar and diabetes.
2. Liver-Kidney-Cardiovascular Pathway: A major area of metabolic dysfunction.
Symptoms: Foamy urine, bloating after meals, bitter taste in the mouth in the morning, chest tightness. → Associated with high uric acid, fatty liver, and hypertension.
3. Thyroid-Reproductive Axis Pathway: Women are more susceptible.
Symptoms: Cold hands and feet, irregular periods, hair loss, and energy crashes in the afternoon. → Indicates insulin resistance affecting thyroid function and reducing basal metabolism.
4. Immune-Nervous Pathway: A silent source of inflammation.
Symptoms: Poor sleep, fatigue, recurring mouth ulcers, and low mood. → Internal fat can become a source of inflammation, potentially increasing the risk of cancer.
The Balancing Blood Sugar Metabolism Method: Three Criteria for Choosing the Right Foods
To restore metabolic health, you need to reduce the burden on your pancreas. Professor Song Jun's method focuses on choosing the right foods based on three criteria:
1. Low GI: Choose foods that cause a gradual increase in blood sugar levels (e.g., whole grains instead of white rice; GI ≤ 40). Avoid high-GI foods like steamed buns and sugary drinks.
2. Low II: Some foods may not have a high GI, but they can still cause excessive insulin secretion (e.g., milk and steak); limit their intake over time.
3. Anti-inflammatory properties: Choose foods that reduce inflammation (e.g., leafy greens, berries, and deep-sea fish), and avoid processed meats and trans fats that exacerbate inflammation.
The Balanced Blood Sugar Meal Plan + Eating Order: Simple and Easy to Follow
There's no need to memorize complicated recipes; just remember these two key points:
- Meal composition: Half of your plate should be filled with leafy greens (e.g., spinach and broccoli), a quarter with protein (e.g., eggs, fish, or soy products), and a quarter with carbohydrates (e.g., whole grain rice or sweet potatoes).
- Eating order: Start with vegetables (fiber provides a buffer that slows down carbohydrate absorption), then consume protein (to activate digestive enzymes), and finally eat carbohydrates (to allow glucose to enter the bloodstream slowly and release insulin steadily).
For example, if you eat out for lunch, finish the vegetables first, then the meat, and lastly the rice to minimize blood sugar spikes.
Personalized Approaches: No One-Fits-All Diet
Everyone's metabolism is different:
- Office workers: No time to cook? Choose convenient low-GI options like whole wheat bread with eggs and a vegetable salad.
- Elderly at home: Poor digestion? Try soft, easily digestible whole grain porridge with steamed eggs and boiled vegetables.
- Stressed women: Eat more anti-inflammatory foods (e.g., deep-sea fish and nuts) and avoid high-sugar snacks.
The key is to pay attention to how your body reacts to different foods—do you feel tired in the afternoon or have trouble sleeping at night after eating certain foods? Adjust your diet accordingly to find what works best for you.
In conclusion, metabolic health isn't about meeting the "normal" criteria on a medical test report; it's about paying attention to the details of your daily diet. Make changes starting with your next meal—eat vegetables first, then protein, and finally carbohydrates. Eating well is the best way to maintain good health.
