I'm too thin..?


Hello, doctor.
I am 19 years old, about 175 cm tall, but I only weigh around 54 kg, not even 55.
I feel that I am quite underweight.
However, I can't seem to gain weight.
Is it because I have poor absorption? Are there any methods to help me gain weight more easily? Please provide your insights, thank you!

Actually, as long as you are healthy, it's not necessary to be overly concerned about being too thin.
You can also engage in weight training to increase your muscle mass.

Gaining weight can be a challenging endeavor, especially for individuals who naturally have a fast metabolism or struggle with appetite. At 19 years old, with a height of 175 cm and a weight of 54 kg, your Body Mass Index (BMI) is approximately 17.6, which is considered underweight. It’s essential to approach weight gain in a healthy manner, focusing on both nutrition and lifestyle changes.


Understanding Your Body
Firstly, it’s important to understand that weight gain is fundamentally about consuming more calories than your body burns. If you find it difficult to gain weight, it could be due to several factors, including high metabolism, insufficient caloric intake, or even underlying health issues that affect nutrient absorption. Conditions such as hyperthyroidism, diabetes, gastrointestinal disorders, or malabsorption syndromes can contribute to difficulty in gaining weight. Therefore, if you suspect that your body is not absorbing nutrients properly, it would be wise to consult a healthcare professional for a thorough evaluation.


Nutritional Strategies for Weight Gain
1. Increase Caloric Intake: Aim to consume more calories than you burn. This can be achieved by increasing portion sizes and eating more frequent meals. Instead of three meals a day, consider having five to six smaller meals throughout the day.

2. Choose Nutrient-Dense Foods: Focus on foods that are high in calories but also provide essential nutrients. Examples include:
- Nuts and Nut Butters: Almonds, walnuts, and peanut butter are high in healthy fats and calories.

- Dairy Products: Full-fat milk, yogurt, and cheese can add significant calories and protein.

- Whole Grains: Foods like oatmeal, brown rice, and whole grain bread are good sources of carbohydrates and can help increase caloric intake.

- Healthy Oils: Incorporate olive oil, avocado oil, or coconut oil into your meals for added calories.

3. Protein-Rich Foods: Include sources of protein in every meal to support muscle growth. Good options include lean meats, fish, eggs, dairy, legumes, and protein shakes.

4. Snacking: Incorporate healthy snacks between meals. Options like trail mix, protein bars, smoothies, or cheese and crackers can help increase your overall caloric intake without making you feel overly full.

5. Liquid Calories: Sometimes, drinking your calories can be easier than eating them. Consider smoothies, milkshakes, or meal replacement drinks that are high in calories and nutrients.


Lifestyle Changes
1. Strength Training: Incorporating resistance training into your routine can help you gain muscle mass rather than just fat. This can also stimulate your appetite. Aim for 2-3 sessions per week focusing on major muscle groups.

2. Avoid Empty Calories: While it might be tempting to consume high-sugar or high-fat junk foods to gain weight, these can lead to unhealthy weight gain and do not provide the nutrients your body needs.

3. Regular Eating Schedule: Try to eat at the same times each day to help establish a routine. This can help your body get used to eating more frequently.

4. Stay Hydrated: While hydration is important, try to avoid drinking large amounts of water before meals, as this can fill you up and reduce your appetite.

5. Monitor Your Progress: Keep track of your weight and dietary intake to see what works best for you. Adjust your strategies based on your progress.


Conclusion
Gaining weight healthily takes time and patience. It’s crucial to focus on nutrient-dense foods and maintain a balanced diet while incorporating strength training to build muscle. If you continue to struggle with weight gain despite these efforts, or if you have concerns about your appetite or digestion, it’s advisable to consult with a healthcare professional or a registered dietitian. They can provide personalized guidance and check for any underlying health issues that may be affecting your ability to gain weight. Remember, the goal is to achieve a healthy weight in a sustainable manner, ensuring your overall well-being.
