Body changes
Hello, doctor.
I am currently a ninth-grade student, with a height of 156 cm and a weight of 65 kg.
Since I started junior high school, my weight has been continuously increasing, but my height hasn't changed much.
When I graduated from elementary school, I was 150 cm tall and weighed 35 kg.
My height has only increased by 6 cm, but my weight has increased by 30 kg.
However, my eating habits haven't changed.
Most of my weight gain occurs during the summer and winter vacations.
Can you explain why this is happening?

Dr. Hong Yuanbin reply Internal Medicine
Hello, weight gain is primarily related to two issues: diet and exercise.
Regarding diet, it is common to unconsciously eat too much or consume overly fatty foods during vacation periods, which increases caloric intake.
In terms of exercise, typically, both daily activities and exercise levels decrease during holidays.
These two factors are likely responsible for weight gain.
It is recommended to avoid snacks and fried foods, and to engage in at least 30 minutes of sweating exercise at least three times a week.
Another factor is that as we age, everyone's basal metabolic rate tends to decline, meaning we can no longer indulge in food or remain inactive as we did in the past.
This is particularly noticeable after the age of 20 and becomes more pronounced after 30.
Thank you for your question.

Understanding weight gain during adolescence can be a complex issue, as it involves a variety of biological, psychological, and social factors. During adolescence, individuals experience significant hormonal changes that can affect metabolism, appetite, and body composition. In your case, the rapid weight gain you experienced after entering middle school, despite no significant changes in your eating habits, can be attributed to several factors.
Firstly, puberty is a time of rapid growth and development. Hormones such as estrogen and testosterone play crucial roles in this process. These hormones can lead to an increase in body fat, particularly in females, as the body prepares for potential reproductive functions. This is a normal part of development, and it can sometimes result in a higher weight without a corresponding increase in height.
Secondly, your observation that most of your weight gain occurs during school breaks could be linked to changes in your daily routine. During the school year, you may have a more structured schedule that includes physical activity, such as walking to school or participating in sports. Conversely, during breaks, you might be less active, leading to an increase in weight. It's important to maintain a balance of physical activity throughout the year, regardless of your schedule.
Additionally, psychological factors can also play a role in weight gain during adolescence. Stress, anxiety, and changes in social dynamics can lead to emotional eating or changes in appetite. If you are feeling overwhelmed with school or social pressures, it might manifest in your eating habits, even if you are not consciously aware of it.
Moreover, it’s essential to consider the role of metabolism. As you grow, your body’s metabolic rate can change. Some adolescents may experience a slower metabolism, which can contribute to weight gain if caloric intake exceeds energy expenditure. This is particularly relevant if you are consuming high-calorie foods or snacks, even if your overall diet seems consistent.
To address your concerns about weight gain, it may be helpful to focus on a few key strategies:
1. Balanced Diet: Ensure that your diet includes a variety of foods, focusing on whole grains, lean proteins, fruits, and vegetables. Limiting sugary snacks and beverages can also help manage weight.
2. Regular Physical Activity: Aim for at least 60 minutes of moderate to vigorous physical activity most days of the week. This can include sports, walking, biking, or any activity that you enjoy.
3. Mindful Eating: Pay attention to your hunger cues and try to eat when you are hungry rather than out of boredom or stress. Eating slowly and savoring your food can also help you recognize when you are full.
4. Seek Support: If you find it challenging to manage your weight or if you have concerns about your body image, consider talking to a healthcare professional, such as a doctor or a nutritionist. They can provide personalized advice and support.
5. Mental Health: If you are experiencing stress or anxiety, it may be beneficial to speak with a counselor or therapist. Mental health is closely linked to physical health, and addressing any underlying issues can help improve your overall well-being.
In conclusion, weight gain during adolescence is a common experience influenced by various factors, including hormonal changes, lifestyle habits, and psychological aspects. By focusing on healthy eating, regular physical activity, and seeking support when needed, you can better manage your weight and promote a healthier lifestyle. Remember, it’s essential to approach this journey with patience and self-compassion, as your body is going through significant changes during this time.
