A Taiwanese nurse’s sons lost a combined 110 pounds simply by cutting out one beverage—and experts say the strategy could help millions combat fatty liver disease.
In a recent episode of the Taiwanese television program Little Universe Big Explosion, Linkou Chang Gung Memorial Hospital senior nurse Tan Dun-ci shared a remarkable family weight-loss story that has captured widespread attention. Her younger son dropped from 100 kilograms (220 pounds) to 70 kilograms (154 pounds)—a loss of 30 kilograms (66 pounds)—while her elder son shed 20 kilograms (44 pounds). The secret? Eliminating a single type of drink from their daily routines.
The One Drink That Made the Difference
According to Tan, both sons were heavy consumers of sugary beverages before their transformations. By cutting out sweetened drinks entirely, the brothers achieved significant weight loss without extreme dieting or intensive exercise regimens. The younger son, a university student, maintained his new habits for one year to reach his target weight.
The nurse emphasized that the change was not about deprivation but about replacing empty calories with healthier alternatives. Water, unsweetened tea, and black coffee became the go-to options, dramatically reducing daily sugar intake.
Why Sugary Drinks Are a Hidden Danger
Medical experts point to sugary beverages as one of the primary contributors to visceral fat—the dangerous fat stored deep within the abdomen that wraps around internal organs. Unlike subcutaneous fat, visceral fat is linked to serious health conditions including type 2 diabetes, heart disease, and fatty liver disease.
Dr. Li Tang-yue, a family medicine specialist who appeared on the same program, explained that reducing sugar consumption directly targets this harmful fat. He emphasized that when the liver is overwhelmed by excess sugar, it converts the surplus into fat, leading to fatty liver disease—a condition affecting an estimated 25% of adults worldwide.
Five Essential Nutrients for Fighting Visceral Fat
Dr. Li outlined five key nutrients that help combat internal fat accumulation:
- Dietary fiber – Found in vegetables, fruits, and whole grains, fiber slows sugar absorption and promotes satiety
- Omega-3 fatty acids – Present in fatty fish, flaxseeds, and walnuts, these healthy fats reduce liver inflammation
- Antioxidants – Berries, dark leafy greens, and citrus fruits help neutralize oxidative stress linked to fat storage
- Probiotics – Fermented foods like yogurt and kimchi support gut health, which influences metabolism
- Protein – Lean meats, eggs, and legumes boost metabolism and reduce cravings
16 Foods That Target Internal Fat
Dr. Li Tang-yue, a family medicine specialist, recommended 16 specific foods to combat visceral fat. These include:
- Oats, quinoa, and brown rice for sustained energy
- Salmon, mackerel, and sardines for omega-3s
- Broccoli, spinach, and kale for fiber and antioxidants
- Avocados and nuts for healthy fats
- Green tea and coffee for metabolism-boosting compounds
- Legumes and lentils for plant-based protein
- Berries and citrus fruits for vitamin C
- Turmeric and ginger for anti-inflammatory properties
The Fatty Liver Connection
Fatty liver disease occurs when fat makes up more than 5% of the liver’s weight. It is often asymptomatic in early stages but can progress to inflammation, scarring, and even liver failure if left unchecked.
Taiwanese dietitian Cheng Han-yu emphasized that reversing fatty liver requires three core habits: healthy eating, weight loss, and regular exercise. She identified 10 liver-protective foods that support this process, including:
- Garlic and onions, which activate liver enzymes
- Leafy greens like spinach, which neutralize heavy metals
- Cruciferous vegetables such as broccoli, which boost detoxification
- Beets and carrots, rich in plant flavonoids
- Avocados, which produce glutathione—a key antioxidant
- Walnuts, high in omega-3s
- Olive oil for healthy fat intake
- Green tea, linked to improved liver enzyme levels
- Lemons and limes, which aid digestion
- Turmeric, known for its anti-inflammatory properties
The Science Behind the Strategy
Visceral fat, often invisible from the outside, poses greater health risks than subcutaneous fat. When the liver’s fat content exceeds 5%, it is classified as fatty liver disease—a condition that affects approximately one in four adults globally.
Dr. Li emphasized that reducing sugar intake is one of the most effective ways to lower liver fat. Sugary drinks, in particular, deliver a rapid glucose spike that the liver cannot process efficiently, leading to fat storage. By cutting out these beverages, the body begins to metabolize existing fat stores instead.
A Broader Health Crisis
The brothers’ story reflects a growing global concern. According to the World Health Organization, obesity rates have nearly tripled since 1975, and non-alcoholic fatty liver disease has become the most common chronic liver condition worldwide. In Hong Kong, where sugary milk tea and soft drinks are dietary staples, health experts warn that hidden sugars contribute significantly to rising obesity and liver disease rates.
Tan’s approach aligns with recommendations from nutritionists worldwide: small, sustainable changes yield lasting results. Her sons did not follow restrictive fad diets or undergo extreme exercise programs. They simply removed one category of products from their consumption habits.
Expert-Backed Strategies for Reducing Liver Fat
Dietitian Cheng Han-yu emphasized that reversing fatty liver requires three fundamental lifestyle adjustments: balanced nutrition, gradual weight reduction, and consistent physical activity. She noted that even a 5% reduction in body weight can significantly decrease liver fat content.
For those looking to follow the brothers’ example, experts recommend:
- Replace sugary sodas, fruit juices, and sweetened teas with water or unsweetened beverages
- Incorporate high-fiber foods to slow glucose absorption
- Choose whole foods over processed options
- Aim for 150 minutes of moderate exercise weekly
- Monitor portion sizes, particularly for carbohydrate-rich meals
The Hidden Danger of Visceral Fat
Visceral fat, which accumulates around internal organs, is metabolically active and releases inflammatory compounds. Unlike the pinchable fat under the skin, this deep fat cannot be seen or felt—making it particularly dangerous. Fatty liver disease often shows no symptoms until significant damage has occurred.
Dr. Li warned that individuals with a waist circumference exceeding 90 centimeters for men or 80 centimeters for women face elevated risks. He recommended regular health screenings, including liver function tests and abdominal ultrasounds, for those with family histories of obesity or diabetes.
Practical Steps for Readers
For Hong Kong residents looking to replicate the brothers’ success, experts suggest:
- Start with one change: Replace sugary drinks with water or unsweetened tea for 30 days
- Read labels carefully: Many seemingly healthy beverages contain hidden sugars
- Track progress: Measure waist circumference monthly rather than relying solely on scale weight
- Combine with movement: Even 20-minute daily walks accelerate fat loss
- Consult a professional: Blood tests can reveal early signs of fatty liver disease
The Bigger Picture
Tan’s family story underscores a critical public health message: small dietary adjustments can produce dramatic outcomes. With obesity rates climbing across Asia and fatty liver disease affecting younger populations, the simple act of eliminating sugary drinks could have far-reaching implications.
Medical professionals urge individuals to view weight management not as a short-term fix but as a lifelong commitment. The brothers’ success demonstrates that sustainable change begins with one conscious choice—and that choice, for many, starts with what they pour into their glass.
