A small belt can reveal much about one's health. A larger waist circumference increases the risk of hypertension, heart disease, and other conditions. The longer the belt, the shorter the life expectancy. According to the National Fitness Monitoring Report, obesity and overweight rates among Chinese citizens have surged significantly over the past two decades, with belts growing progressively longer.This issue, we invited Professor Hong Zhaoguang, Chief Health Education Expert at the Ministry of Health, to share secrets for reducing waist size.
Many assume that compared to Westerners, China has relatively few overweight individuals. However, research published by Shanghai Jiao Tong University reveals that China's obesity growth rate now ranks second globally, trailing only Mexico. A survey conducted by Life Times in collaboration with Sohu Community also indicates that over 90% of participants observed an increasing number of overweight people in their surroundings.Specifically, 39.8% of respondents saw their waistlines increase by 1–2 cm over the past five years, 31.7% gained 3–4 cm, 12.2% added 5–6 cm, and 4.4% expanded by more than 8 cm. Many also reported gaining around 10 jin (approximately 5 kg) in body weight within the same period.
The Ministry of Health's Guidelines for the Prevention and Control of Overweight and Obesity in Chinese Adults clearly define waist circumference thresholds: ≥85 cm for men and ≥80 cm for women. An expanding waistline signals obesity, widely recognized as a precursor to hypertension and diabetes. Obesity can lead to a range of diseases including hypertension, diabetes, heart disease, cancer, cholecystitis, and arthritis.As early as 1996, the International Obesity Task Force warned that obesity would become the greatest threat to human health and quality of life in the 21st century. The World Cancer Research Fund reported that for every additional inch of waist circumference, the risk of cancer increases eightfold. The World Heart Federation predicted that obesity could surpass smoking as the leading cause of heart disease and stroke.Professor Hong Zhaoguang cited a case of a 38-year-old patient who died suddenly. Weighing 99 kilograms, autopsy revealed his heart was completely enveloped by a 3-centimeter-thick layer of fat, with 95% of his coronary arteries blocked by fat deposits. Such severe abdominal obesity is extremely dangerous.Generally, abdominal obesity often coexists with fatty liver disease, hyperlipidemia, diabetes, hypertension, and coronary heart disease. Therefore, reducing waist circumference to prevent heart disease and other metabolic disorders has become an urgent health priority for the Chinese population.
Reducing waist circumference starts with small daily habits. During the interview, Professor Hong Zhaoguang summarized the "secrets to waist reduction" into seven beneficial lifestyle practices.
Maintain good posture: Keep your back straight and pull in your stomach.
What posture are you using to read this article right now? Are you half-reclining on the sofa or leaning back in your office chair? Throughout daily activities like walking, standing, sitting, and lying down, people naturally gravitate toward the most comfortable positions. However, comfortable postures aren't necessarily healthy—especially for those whose waistlines are expanding.Maintaining "comfortable" postures for extended periods not only accumulates belly fat and strains muscles and ligaments but can even impair cardiovascular function. Conversely, consistently holding a posture with a straight back and tucked-in abdomen actually exercises abdominal muscles, proving highly effective for reducing waist size over time.
Those who work long hours hunched over desks should stand and walk around every half hour. When walking, keep your head up, chest out, eyes level, and toes pointing straight ahead. Take natural strides with a light, brisk pace. When standing, slightly tuck your chin in, gently tighten your abdomen, and shift your center of gravity slightly forward.
Prioritize Aerobic Exercise
Exercise falls into two categories: aerobic and anaerobic.While anaerobic exercise builds muscle and explosive power, its fitness benefits are limited to sculpting body contours and generally fall short of aerobic exercise. Therefore, those aiming to reduce waist circumference should prioritize aerobic activities.
Common aerobic exercises ranked by calorie burn include: track and field, jumping rope, cycling, jogging, basketball, table tennis, swimming, and walking.Among these, brisk walking, swimming, dancing, and cycling are the four exercises most recommended by the U.S. "Daily Health Network" for heart health. They effectively improve cardiopulmonary function while also lowering blood pressure, regulating blood lipids, and controlling blood sugar, making them particularly suitable for middle-aged and elderly individuals. Each aerobic session should last no less than 30 minutes, performed 3–5 times weekly.Maintain proper exercise intensity by keeping your heart rate close to but not exceeding your "target heart rate." Generally, the target heart rate equals 170 minus your age. If you experience significant palpitations, shortness of breath, chest warmth, or dizziness, it indicates overexertion. Good Food: One Meat, One Vegetable, One Fungus A balanced diet is crucial for anyone aiming to manage their waistline.Remember these two key principles: "One, Two, Three, Four, Five" and "Red, Yellow, Green, Black, White." One: Drink one carton of milk daily. Two: Consume 250–350 grams of carbohydrates, equivalent to 6–8 ounces of staple foods. Three: Include three servings of high-protein foods.One serving equals 50 grams of lean meat, one large egg, 100 grams of tofu, 100 grams of fish/shellfish, 150 grams of chicken/duck, or 25 grams of soybeans. Four: Four guidelines—"Include both coarse and refined grains, avoid excessive sweetness or saltiness, eat three to five meals daily, and stop when 70-80% full." Five: 500 grams of vegetables and fruits. Prioritize colorful foods. "Red": tomatoes, red wine (in moderation), red peppers, etc."Yellow": Carrots, sweet potatoes, corn, pumpkin, etc. "Green": Green tea. Regular consumption promotes longevity, reduces tumor risk, and slows arteriosclerosis. Green vegetables are rich in vitamins and minerals, with darker hues indicating higher nutritional value. "Black": Black foods like black fungus lower blood viscosity. "White": Oatmeal, paired with soy products and garlic.
Professor Hong also recommends a weight-loss meal plan: one meat, one vegetable, and one mushroom (edible fungi) per meal. Breakfast: 1 ounce of "Four-Color Nutritious Porridge," 1 boiled egg (with half the yolk removed), 250ml milk; Lunch: 1 ounce rice, 2 ounces steamed fish, 5 ounces cucumber and black fungus salad, 5 ounces raw tomatoes;Dinner: 3 ounces of braised chicken, 5 ounces of braised cabbage (with mushrooms and a small amount of dried shrimp), 1 ounce of rice, and 1 ounce of mung bean and oatmeal porridge. Total daily oil intake: 15 grams; salt: 3 grams. Eating until 70% full at each meal, overweight or obese individuals, or those with hypertension, fatty liver, or coronary heart disease can generally lose about 1 kilogram per month.
Healthy Beverages: Plain Water and Light Tea
Sugary drinks are the enemy of a slim waistline. Joint research by British and American scientists shows that consuming over 355 ml of sweet fruit juice or carbonated beverages daily puts extra pressure on blood vessels. The American Heart Association recommends limiting carbonated drinks to no more than 3 cans (355 ml) per week.
In fact, the best beverages are plain water or lightly brewed tea; honey water, soy milk, and lemon water can also be consumed in moderation. Professor Hong Zhaoguang recommends a "water drinking schedule" to help you easily meet your daily hydration goals. 6:30 AM: Upon waking, drink 250 ml of water to aid kidney and liver detoxification.8:30 AM: Upon arriving at the office, drink at least 250 ml of water. 11:00 AM: Drink your third glass of water to replenish lost fluids and help ease work-related tension. 12:50 PM: Half an hour after lunch, drink some water to aid digestion. 3:00 PM: Drink a glass of water to refresh your mind.5:30 PM: Before leaving work, drink another glass of water to prevent overeating during dinner. 10:00 PM: Drink one more glass of water 1 to 1.5 hours before bedtime, but avoid excessive amounts to prevent sleep disruption. Essential Tools: Scale & Waist Measurer Scale: Keeping a scale at home allows you to monitor weight changes and helps family members track their weight management.As noted by Health magazine's website, effective weight management significantly benefits heart health. We recommend weighing yourself weekly to monthly. If weight gain trends emerge, adjust promptly. A BMI between 18 and 24 is considered optimal. Waist Tape Measure: A standard flexible tape measure suffices. Keep it in a visible spot at home to cultivate regular waist measurement habits.The correct method for measuring waist circumference is as follows: Stand naturally upright with feet shoulder-width apart. Place a non-elastic tape measure at the midpoint between the top of the hip bone and the bottom of the twelfth rib (typically the narrowest natural part of the waist). Wrap the tape horizontally around the abdomen, ensuring it lies flat against the skin without digging in. Measure at the end of a normal exhalation.It's best to have a family member assist with measurement to avoid visual errors. Waist circumference ≥85 cm for men and ≥80 cm for women marks the threshold for being considered overweight.
