A friend lost significant weight in just a few months. Everyone is complimenting his new image, but you find that his face is dull and his mental state is not good. He used a popular method of rapid weight loss, but it came at the cost of his health. This begs the question: Is the real goal of weight loss just to look thinner, or is it about living a healthier, more active life?
In the pursuit of an ideal weight, we often fall into the misconception that all ways to lose weight are healthy. However, the truth is far from simple. As a doctor, I've seen countless patients suffer from physical damage and even long-term deterioration in their health due to the wrong way to lose weight.
What needs to be understood in the scientific approach to healthy weight loss is the concept of energy balance. At the heart of this concept lies in the relationship between energy intake and energy expenditure. Put simply, when you consume more calories (through food) than your body consumes (through daily activities and metabolism), the excess calories are converted into fat and stored, leading to weight gain. Conversely, when you consume more calories than you consume, your body starts using stored fat for energy, which leads to weight loss.
Management of energy intake:
Nutritional balance is key: losing weight doesn't mean you have to drastically reduce your food intake, it's about making the right food choices. Emphasize that meals contain enough protein, healthy fats, and complex carbohydrates, while reducing the intake of processed and high-sugar foods.
Quantity control: Know the caloric density of food and avoid excessive intake, but also not over-restrict to avoid malnutrition.
Optimization of energy consumption:
Moderate increase in physical activity: This refers not only to physical activity, but also to the amount of activity in daily life, such as walking, housework, etc。These activities increase overall energy expenditure and help with weight management.
Understanding of Metabolism: Metabolism is the energy required by the body for normal functions such as breathing, maintaining body temperature. Understanding your basal metabolic rate (BMR) is essential to understanding your daily calorie requirements.
Avoid extreme practices:
Hunger dieting is not encouraged: Extreme dietary restrictions are not only difficult to maintain in the long term, but can also lead to a decrease in the body's metabolism, as well as other health problems.
Focus on long-term lifestyle changes: Long-lasting, healthy weight management should be a gradual process that involves ongoing lifestyle adjustments, rather than drastic changes in the short term.
Throughout the weight loss journey, it's important to take a holistic, balanced approach that focuses on nutritional quality and increases physical activity while avoiding impractical quick fixes.
In the pursuit of healthy weight loss, many people tend to fall into some common misconceptions. These myths not only hinder effective weight loss, but can also have negative health effects. Here are a few common weight loss myths and their scientific counterbuttals:
The pitfalls of the rapid weight loss method
Myth description: Many people believe that rapid weight loss will show immediate results, so they tend to choose extreme dieting or excessive exercise.
Scientific Refutation: Rapid weight loss usually involves the loss of water and muscle mass, rather than true fat loss. In addition, this method can easily lead to a decrease in metabolism, and once you return to a normal diet, you are likely to gain weight**. In the long run, this method is not good for your health and may cause problems such as malnutrition and osteoporosis.
The risk of extreme dieting
Myth: Some people who lose weight think that extreme food restriction is an effective way to lose weight.
Scientific Refutation: Extreme dieting can lead to a state of starvation, which not only affects daily vitality and productivity, but can also lead to serious health problems such as endocrine disorders, decreased immunity. Long-term extreme dieting can lead to changes in the body's absorption and utilization of food, making it harder to lose weight.
Over-reliance on weight-loss supplements
Myth description: Many weight-loss supplements on the market claim to be able to lose fat quickly, appealing to consumers who are looking for quick results.
Scientific Refutation: Most weight-loss supplements are not scientifically proven and may contain ingredients that are harmful to health. It is unwise to rely on these supplements and neglect a healthy diet and moderate exercise. Weight loss should be a comprehensive lifestyle adjustment process that includes eating properly and exercising moderately.
When it comes to healthy weight loss, we need to focus not just on short-term results, but on long-term health and sustainability. Here are some weight-loss strategies based on medical knowledge and scientific research to help you lose weight in a healthy way.
Eating a balanced diet: the art of nutrition
Well-rounded: A healthy eating plan should include nutrients such as protein, healthy fats, complex carbohydrates, and rich in vitamins and minerals. Emphasize the diversity of foods and avoid excessive amounts of single foods or nutrients.
Portion control: Proper portion sizes can help control total caloric intake, but should not be overly restrictive and lead to nutrient deficiencies.
Moderate Exercise: The Wisdom of Moving
Combine cardio with strength training: Aerobic exercises such as brisk walking, running, swimming, etc., can help burn fat, while strength training helps to increase muscle mass and increase metabolic rate.
Perseverance: Exercise should be a long-term lifestyle, not a short-term burst of intensity.
Sleep and stress management: a mental health perspective
Get enough sleep: Lack of sleep can interfere with hormonal balance and increase hunger and appetite. Getting enough sleep is essential for weight loss.
Effective stress management: Long-term stress can lead to increased levels of cortisol in the body, affecting body weight. Learning stress management techniques such as meditation, yoga or other relaxation techniques can be beneficial for weight loss.
Healthy eating habits: the key to longevity
Eat regularly: Establish a regular eating habitAvoid overeating.
Drink plenty of water: Adequate water intake helps with metabolismand may reduce excessive eating.
Mindset & Motivation: The Power of Perseverance

Stay positive:Maintain a positive, optimistic mindset and accept that weight loss is a gradual process.
Healthy weight loss should not only focus on weight numbers, but also on overall lifestyle and long-term health. By adopting these strategies, combined with the specific situation and needs of the individual, healthy and long-lasting weight management can be achieved. Remember, weight loss is a marathon, not a sprint.
