Weight loss help


Hello, doctor: This year, I am in the third year of junior high school, 167.5 cm tall and weigh 58 kg.
Although my BMI is normal, I would like to reduce my weight to 50 kg.
Is this an appropriate age for weight loss? When is the time I can stop growing, and what is the suitable age for losing weight? Thank you.

Hello! I want to weigh 50 kilograms, but that's just a number; what you should really care about is your body shape! For example, your arms could be a bit slimmer, and your thighs could be a bit thinner, etc.
During the growth and development period, it's important to have proper nutrition.
You can achieve a balanced intake of various foods, but also increase your physical activity.
Exercise can help you grow taller, and as your height increases, your body proportions will change.
At any time when trying to lose weight, it should be done with balanced nutrition in mind.
Following an unnutritious weight loss diet will not only reduce your weight but also compromise your health.
I recommend that you visit a nutrition consultation clinic to discuss your needs with a dietitian.

More Info


At the age of 15, your body is still undergoing significant growth and development, which makes it crucial to approach weight loss with caution. While your current BMI of approximately 20.7 falls within the normal range, your desire to reduce your weight to 50 kg could potentially lead to health issues if not managed properly.
During adolescence, the body requires adequate nutrition to support growth, hormonal changes, and overall health. It is essential to understand that weight loss should not be the primary focus at this stage; instead, fostering healthy eating habits and engaging in regular physical activity should be prioritized.

Growth and Nutritional Needs
1. Growth Patterns: Most individuals experience their final growth spurts during their teenage years, which can last until the late teens or early twenties. Factors such as genetics, nutrition, and overall health influence when growth plates close, marking the end of height increase. For girls, this typically occurs around ages 16-18, while boys may continue growing until their early twenties.

2. Nutritional Requirements: As a teenager, your body requires a balanced intake of macronutrients (carbohydrates, proteins, and fats) and micronutrients (vitamins and minerals) to support growth and development. The average caloric intake for a 15-year-old girl can range from 1,800 to 2,400 calories per day, depending on activity level. Severely restricting calories can lead to nutritional deficiencies, which may hinder growth and lead to long-term health issues.

3. Healthy Weight Management: Instead of focusing solely on weight loss, aim for a balanced approach that includes:
- Balanced Diet: Incorporate a variety of foods from all food groups. Focus on whole grains, lean proteins, healthy fats, fruits, and vegetables. Avoid extreme diets or cutting out entire food groups, as this can lead to nutrient deficiencies.

- Regular Physical Activity: Engage in at least 60 minutes of moderate to vigorous physical activity most days of the week. This can include sports, dancing, swimming, or even brisk walking. Exercise not only helps with weight management but also supports mental health and overall well-being.

- Mindful Eating: Pay attention to hunger and fullness cues. Eating slowly and without distractions can help you enjoy your meals more and prevent overeating.


When to Consider Weight Loss
If you are considering weight loss, it is essential to do so under the guidance of a healthcare professional, such as a registered dietitian or a physician. They can help assess your individual needs and create a personalized plan that supports your health without compromising your growth.

Conclusion
In summary, while it is understandable to want to manage your weight, it is crucial to prioritize your health and development at this age. Focus on establishing healthy habits that will benefit you in the long run rather than aiming for a specific weight. Remember, your body is still growing, and ensuring you provide it with the necessary nutrients is vital for your overall health and well-being. If you have concerns about your weight or nutrition, consider discussing them with a healthcare provider who can offer tailored advice and support.
