How can I gain weight?


I just started high school this year, and I am 164 cm tall and weigh 34 kg, which gives me a severely inadequate BMI.
As a result, I haven't had my menstrual cycle at all, and I'm really worried about myself.
I eat a lot but just can't gain weight; I eat everything and also enjoy running and jumping around.
I would like to know how I can gain weight.
My development is also not good, so how can I nourish my body and gain weight?

Hello! Your body weight is quite low.
I recommend that you keep a record of your daily dietary intake, including all solid and liquid foods (including water and various supplements) from morning until bedtime.
Please provide me with this information so I can assess your dietary issues and offer appropriate advice.
Additionally, considering your age and the fact that you have not yet menstruated, it would be best to consult a gynecologist or a traditional Chinese medicine practitioner.
Wishing you health and happiness! Sincerely, Dietitian Shih Kuei-Mei, Director of the Nutrition Department, Taoyuan Hospital, Ministry of Health and Welfare.

Gaining weight healthily, especially for teens struggling with a low BMI, requires a balanced approach that includes proper nutrition, exercise, and lifestyle changes. Given your height of 164 cm and weight of 34 kg, your BMI is indeed significantly below the normal range, which can lead to various health issues, including delayed menstruation and potential developmental concerns. Here are some strategies to help you gain weight in a healthy manner:

Nutritional Strategies
1. Increase Caloric Intake: To gain weight, you need to consume more calories than your body burns. Aim for a caloric surplus by incorporating calorie-dense foods into your diet. Foods such as nuts, seeds, avocados, whole grains, and healthy oils (like olive oil) can help you increase your caloric intake without having to eat large volumes of food.

2. Frequent Meals and Snacks: Instead of sticking to three meals a day, try to eat five to six smaller meals throughout the day. Include snacks like yogurt, smoothies, protein bars, or nut butter on whole-grain bread. This approach can help you consume more calories without feeling overly full.

3. Focus on Nutrient-Rich Foods: While it’s important to increase calories, prioritize nutrient-dense foods that provide vitamins and minerals essential for growth and development. Include a variety of fruits, vegetables, whole grains, lean proteins (like chicken, fish, eggs, and legumes), and healthy fats in your diet.

4. Protein Intake: Ensure you are getting enough protein, as it is crucial for muscle growth and repair. Aim for sources like eggs, dairy products, legumes, and lean meats. Consider adding protein shakes or smoothies to your diet, especially post-workout, to help with muscle recovery and growth.

5. Healthy Fats: Incorporate healthy fats into your meals. Foods like avocados, nuts, seeds, and fatty fish (like salmon) are excellent sources of healthy fats that can help you increase your caloric intake without excessive volume.


Exercise Strategies
1. Strength Training: While cardio is great for overall health, incorporating strength training into your routine can help you build muscle mass, which contributes to weight gain. Focus on exercises that target major muscle groups, such as squats, deadlifts, and bench presses. Aim for 2-3 sessions per week.

2. Limit Excessive Cardio: While it’s good to stay active, excessive cardio can burn a lot of calories and hinder your weight gain efforts. Balance your cardio with strength training and consider reducing the duration or intensity of your cardio sessions.


Lifestyle Changes
1. Stay Hydrated: Drink plenty of fluids, but try to avoid filling up on water or low-calorie drinks before meals, as this can reduce your appetite. Instead, opt for calorie-rich beverages like smoothies or milk.

2. Monitor Your Progress: Keep track of your weight and dietary intake to see what works best for you. Adjust your caloric intake based on your progress and how your body responds.

3. Consult a Healthcare Professional: Given your concerns about your development and health, it’s essential to consult with a healthcare provider or a registered dietitian. They can provide personalized advice and monitor your progress to ensure you are gaining weight healthily.

4. Be Patient: Healthy weight gain takes time, just like weight loss. Focus on making gradual changes and celebrate small victories along the way.


Conclusion
Gaining weight healthily is a gradual process that requires a combination of increased caloric intake, balanced nutrition, and appropriate exercise. By focusing on nutrient-dense foods, incorporating strength training, and consulting with healthcare professionals, you can work towards achieving a healthier weight and supporting your overall development. Remember, it’s essential to prioritize your health and well-being over simply increasing numbers on the scale.
