Nutrition, Weight, and Weight Loss During Adolescence
Hello, doctor.
I am a student about to enter my senior year of high school.
In recent semesters, I have received notifications about being overweight during the height and weight measurements at school.
I would like to appropriately lose weight and increase my physical fitness, both to prepare for the upcoming academic challenges and for my overall health.
I would like to ask what dietary adjustments I can make, how I can plan my exercise time and volume, and whether my daily routine will have a significant impact, especially since I often stay up late preparing for exams.
Thank you for your help.

Hello, the senior year of high school is a crucial period in life, and it is important to develop good dietary habits and a regular lifestyle to cope with the busy and high-pressure environment of the final year.
Therefore, it is recommended that you plan your schedule for the summer and the start of the school year.
Firstly, it is advisable to establish a daily routine of regular exercise.
If you do not currently have an exercise habit, you can start with walking.
Begin with a daily 10-minute outdoor walk.
The benefits of walking outdoors include the ability to gaze into the distance, which can relieve the strain on your eyes from prolonged study, and it also provides a relaxing effect.
In terms of diet, you should eat at regular intervals and in appropriate portions, maintaining a consistent meal schedule that aligns with your study times.
This helps prevent poor cognitive function due to hunger and avoids drowsiness from overeating.
Focus on consuming plenty of fruits and vegetables, and choose whole grains that are high in fiber and vitamins, such as whole wheat, brown rice, millet, and quinoa, which are rich in nutrients.
Increasing your intake of fruits, vegetables, and adequate water can help maintain gut health, preventing gastrointestinal discomfort that could affect your study performance.
Incorporate more soy products like tofu, dried tofu, and soy milk, as legumes contain lecithin that nourishes nerve cells.
Fish such as salmon, tuna, mackerel, and sardines are rich in monounsaturated fatty acids, which are essential for brain cell growth.
Consuming two servings of dairy products daily can provide necessary protein and calcium for growth.
Try to avoid sugary beverages, as high-sugar drinks can burden the body and lead to obesity.
A diverse range of natural food nutrients offers many benefits to the body, so it is recommended to eat three regular meals and supplement with fruits between meals, while minimizing the intake of processed foods and snacks.
Your daily routine significantly impacts your mental state, so it is advisable to avoid staying up late.
Good and sufficient sleep greatly affects thinking and memory; to maintain clarity of thought, it is crucial not to develop a habit of staying up late.

More Info
As a high school student preparing for your final year, it's commendable that you're taking proactive steps towards managing your weight and enhancing your physical fitness. Balancing your nutrition, exercise, and sleep is crucial not only for your health but also for your academic performance. Here are some comprehensive tips to help you achieve your goals.
Nutrition Adjustments
1. Balanced Diet: Focus on a well-rounded diet that includes a variety of food groups. Aim for:
- Fruits and Vegetables: Incorporate at least 5 servings of fruits and vegetables daily. They are rich in vitamins, minerals, and fiber, which are essential for overall health and can help you feel full.
- Whole Grains: Choose whole grains over refined grains. Options like brown rice, whole wheat bread, and oats provide more nutrients and fiber, which can aid in digestion and help maintain a healthy weight.
- Lean Proteins: Include sources of lean protein such as chicken, fish, beans, and legumes. Protein is vital for muscle repair and growth, especially if you are increasing your physical activity.
- Dairy: Incorporate low-fat dairy products like yogurt and milk for calcium and protein, which are important for bone health during your growth years.
2. Portion Control: Be mindful of portion sizes. Eating smaller, more frequent meals can help regulate hunger and prevent overeating. Try to listen to your body's hunger cues and eat until you are satisfied, not stuffed.
3. Limit Sugary and Processed Foods: Reduce your intake of sugary drinks, snacks, and fast food. These foods are often high in calories but low in nutritional value. Instead, opt for water, herbal teas, or homemade smoothies.
4. Meal Planning: Consider planning your meals ahead of time. This can help you make healthier choices and avoid the temptation of unhealthy snacks when you're busy studying.
Exercise Recommendations
1. Regular Physical Activity: Aim for at least 150 minutes of moderate-intensity aerobic activity each week, such as brisk walking, cycling, or swimming. You can break this down into manageable sessions, like 30 minutes a day, five days a week.
2. Strength Training: Incorporate strength training exercises at least twice a week. This can include bodyweight exercises like push-ups, squats, and lunges, or using resistance bands. Strength training helps build muscle, which can increase your metabolism.
3. Active Breaks: If you find yourself studying for long periods, take short breaks to stretch or do quick exercises. This can help improve circulation and keep your energy levels up.
Sleep and Study Habits
1. Prioritize Sleep: Sleep is crucial for cognitive function, mood regulation, and overall health. Aim for 7-9 hours of quality sleep each night. Establish a regular sleep schedule by going to bed and waking up at the same time every day, even on weekends.
2. Limit Screen Time Before Bed: Reduce exposure to screens at least an hour before bedtime. The blue light emitted by phones and computers can interfere with your ability to fall asleep.
3. Create a Study Schedule: Organize your study time effectively to avoid late-night cramming. Break your study material into manageable sections and allocate specific times for each subject. This can help reduce stress and improve retention.
Conclusion
By making these dietary adjustments, committing to regular exercise, and prioritizing sleep, you can effectively manage your weight and enhance your overall well-being as you prepare for your final year of high school. Remember, it's important to approach weight management with a focus on health rather than just numbers on a scale. If you find it challenging to make these changes on your own, consider seeking guidance from a healthcare professional or a registered dietitian who can provide personalized advice based on your specific needs. Good luck with your studies and your health journey!
