Obesity Triggers in Different Populations and Science-Based Solutions

Decoding Weight Gain:
Science-Backed Solutions for Every Body Type

Obesity has become one of the most critical global public health challenges, with China facing particularly severe issues. Latest data reveals that over 50% of Chinese adults are now overweight or obese, while childhood obesity rates in rural areas are rising alarmingly fast—projected to surpass urban rates by 2025. Concurrently, scientific research continues uncovering new obesity mechanisms like “browning fat whitening” and metabolic traps in ultra-processed foods, while social phenomena such as “Gen Z’s takeout dieting” are reshaping our understanding of weight management.

2025 Obesity Landscape: The Hidden Crisis Behind the Data

• Adult Obesity Rate
  50.7% (34% overweight + 16% obese)
• Childhood Obesity Trends
  Rural children’s BMI growth rate has surpassed urban areas, with complete “reversal” expected by 2025
• Health Consequences
  Obesity is linked to over 200 diseases, including diabetes, hypertension, and cardiovascular diseases

Causes of Obesity Across Populations

• Rural Children: Westernized diets + insufficient exercise

Background: Rural childhood obesity is growing faster than urban areas, primarily due to dietary patterns converging with cities (high sugar, high fat, fast food) while lacking obesity awareness.

Key Factors:

Diet: Processed foods replacing traditional meals, excessive sugar intake

Exercise: Reduced physical activity due to urbanization, inadequate sports facilities

Awareness: Parents’ insufficient understanding of childhood obesity risks

• Gen Z Office Workers: Stress + Sleep Deprivation + Fragmented Lifestyles

Background: While food delivery gigs have become a trendy side hustle, chronic sleep deprivation and high-pressure work remain primary obesity drivers.

Key Factors:

Hormonal Imbalance: Elevated cortisol levels → abdominal fat accumulation

Sleep Deficiency: 28% decrease in leptin (satiety hormone) + 18% increase in ghrelin (hunger hormone)

Uncontrolled Eating: Frequent takeout meals, late-night snacks, and hidden calories (bubble tea, BBQ)

• Urban Young Adults: Ultra-Processed Foods + Sedentary Lifestyle

Background: A recent Nature study reveals that even when meeting nutritional standards, ultra-processed foods (UPFs) hinder weight loss and metabolic health.

Key Factors:

Food Industry Traps: UPFs (e.g., fast-food bread, candy) disrupt satiety signals, leading to over consumption.

Metabolic Disruption: Additives (emulsifiers, artificial sweeteners) alter gut microbiota, triggering chronic inflammation.

Sedentary Culture: Average daily steps <5,000, reducing basal metabolic rate (BMR) and fat oxidation

• Abdominal obesity

Background: Nearly 30% of obese people in China are “central obesity” and have a higher risk of visceral fat

Key factors:

Genetic predisposition: Asians are more prone to accumulating abdominal fat

Metabolic syndrome: insulin resistance + dyslipidemia

2HG metabolites: The latest research has found that the carcinogen 2HG can cause brown fat to “bleach” and exacerbate obesity

Scientific weight management solutions

Cardiopulmonary fitness

Cardiorespiratory Fitness (CRF) is a “barometer” of health, which involves the combined efficiency of the heart pumping, lung gas exchange, blood circulation and muscle oxygen utilization. The maximum ability of the body to absorb, transport and use oxygen during exercise can be significantly improved by scientific exercise.

Cardiopulmonary function testing and training is a relatively non-invasive, simple, fast, accurate and efficient method of evaluating cardiopulmonary reserve function, exercise endurance and scientific training.

Cardio training

According to epidemiological studies, aerobic training is the basis of exercise training for most patients with cardiovascular disease or adults at risk of cardiovascular disease. This type of training is the most effective way to improve cardiorespiratory fitness.

Through systematic aerobic exercise and high-intensity interval training, cardiopulmonary function reserves can be significantly enhanced. This physiological improvement has dual benefits: on the one hand, it can effectively improve the basal metabolic rate and promote fat oxidation and metabolism; On the other hand, it can optimize the composition ratio of body components. Further, scientific aerobic training not only provides a physiological basis for weight management, but also significantly reduces the risk of obesity-related metabolic diseases.

Vibration training system

The vibration trainer is designed based on the principle of human gait, and stimulates the physiological stretch reflex of the muscles with a vibration frequency of more than 12Hz by simulating the alternating tilting motion of the pelvis during walking, so as to efficiently activate the muscles from the lower limbs to the trunk. This training mode not only enhances muscle coordination and balance, but also significantly promotes blood circulation and metabolism, helping to scientifically manage weight – by increasing basal metabolic rate, accelerating fat metabolism, etc., to achieve more efficient fat burning effects. Its adjustable frequency, amplitude, and training posture allow for personalized solutions tailored to different needs, especially for those who require low-impact, high-performance exercise.

Resistance training system

Resistance training effectively activates the large muscles of the whole body by allowing the target muscle group to perform isotonic contractions against external resistance. Using a training mode of low to medium intensity (10-15 reps/set) can not only significantly improve muscle strength and endurance, but also promote muscle growth, thereby increasing basal metabolic rate. This training method provides a double guarantee for scientific weight management by optimizing body composition (increasing lean body mass and reducing body fat), which can not only directly consume calories during training, but also achieve long-term fat burning by increasing resting metabolic rate.

2025 Weight Management Action Guide

child

Family + school + medical institutions are linked to optimize the dietary structure and ensure daily exercise

office worker

Avoid staying up late and set a fixed schedule

Movement using fragmented time

Abdominal obesity

Focus on monitoring waist circumference (male < 90cm, female < 85cm)

Combined with resistance training + aerobic to reduce visceral fat

All of them

Cut back on ultra-processed foods and choose low-GI foods

Conduct regular cardiopulmonary fitness tests and scientifically adjust the exercise plan

Obesity is not a simple “calorie surplus”

It is the result of multiple factors such as genetics, environment, metabolism, and behavior
