Weight loss


Hello doctor, I am here to ask you how I can lose weight.
Please tell me what I should do.

Hu, 10~19 year old female. Ask Date: 2005/07/19

Dr. Xiao Jingqin reply Internal Medicine


First, you need to calculate your BMI (Body Mass Index: weight divided by height squared, with height measured in meters).
The normal range is generally around 24 plus or minus 2.
If your BMI falls within this range, you are not considered overweight and do not need to lose weight.
If weight loss is necessary, you should first understand your daily caloric intake.
For normal activity, the requirement is about 20-25 calories per kilogram.
For a person weighing 70 kilograms, the daily caloric needs for normal activity are approximately 1400 to 1750 calories.
Most people currently consume around 2000 to 3000 calories per day, so to lose weight, daily caloric intake should be reduced to 15 calories per kilogram.
Additionally, appropriate exercise is necessary for effective weight loss.
As for the caloric content of various foods, it can easily be found on various websites and in books.

To effectively lose weight and improve body composition, it is essential to adopt a holistic approach that combines dietary changes, physical activity, and behavioral modifications. Here are some strategies based on medical expertise that can help you achieve your weight loss goals:

1. Understand Your Body Composition
Before starting any weight loss journey, it's crucial to understand your current body composition. This includes knowing your body mass index (BMI) and body fat percentage. For instance, a BMI over 25 is considered overweight, while a body fat percentage above 30% for women and 25% for men indicates excess fat. Understanding these metrics can help set realistic goals.


2. Set Realistic Goals
Aim for gradual weight loss rather than drastic changes. A safe and sustainable rate of weight loss is about 1-2 pounds per week. This can be achieved by creating a calorie deficit of 500-1000 calories per day through a combination of diet and exercise.


3. Balanced Nutrition
Focus on a balanced diet that includes:
- Fruits and Vegetables: Aim for at least five servings a day. They are low in calories and high in nutrients.

- Lean Proteins: Incorporate sources like chicken, fish, beans, and legumes. Protein helps in muscle retention during weight loss.

- Whole Grains: Choose whole grains over refined grains. They provide fiber, which aids digestion and keeps you full longer.

- Healthy Fats: Include sources of healthy fats such as avocados, nuts, and olive oil, but in moderation.


4. Portion Control
Be mindful of portion sizes. Using smaller plates, measuring food, and being aware of serving sizes can help prevent overeating. Eating slowly and savoring your food can also enhance satiety.


5. Regular Physical Activity
Incorporate both aerobic and strength training exercises into your routine:
- Aerobic Exercise: Activities like walking, running, cycling, or swimming should be done for at least 150 minutes per week.

- Strength Training: Aim for at least two days a week of strength training exercises to build muscle, which can increase your resting metabolic rate.


6. Behavioral Changes
Addressing psychological factors is vital for long-term success:
- Mindful Eating: Pay attention to what you eat and how much. Avoid distractions like watching TV while eating.

- Stress Management: Stress can lead to emotional eating. Techniques such as yoga, meditation, or deep breathing can help manage stress levels.

- Sleep Hygiene: Ensure you get adequate sleep, as poor sleep can disrupt hormones that regulate appetite.


7. Seek Professional Guidance
Consider consulting with a registered dietitian or a healthcare provider who specializes in weight management. They can provide personalized advice based on your health status, dietary preferences, and lifestyle.


8. Stay Hydrated
Drink plenty of water throughout the day. Sometimes, thirst is mistaken for hunger. Staying hydrated can help control appetite and improve overall health.


9. Monitor Progress
Keep a food diary or use apps to track your food intake and exercise. Monitoring your progress can help you stay accountable and make necessary adjustments to your plan.


10. Be Patient and Persistent
Weight loss is a journey that requires time and effort. There may be setbacks along the way, but it's essential to stay committed to your goals. Celebrate small victories and focus on the positive changes you are making in your lifestyle.


Conclusion
In summary, effective weight loss strategies involve a combination of understanding your body, setting realistic goals, adopting a balanced diet, engaging in regular physical activity, and making behavioral changes. Remember, the journey to weight loss is personal and unique for everyone. It's essential to find what works best for you and to seek support when needed. With dedication and the right approach, you can achieve your weight loss goals and improve your overall health.
