How to help the gastrointestinal tract absorb nutrients?


Hello, doctor.
I have a body type that struggles to gain weight, but I really want to put on some pounds.
Are there any methods to help improve nutrient absorption in my digestive system? For example, are there any exercises I can do before or after meals, or specific foods (like fruits) that can enhance absorption? I am 165 cm tall and weigh only 50 kg.
Thank you.

Hello! Your ideal weight range is between 54 to 66 kilograms, and your current weight of 50 kilograms is indeed underweight, so you need to gain weight.
Exercising about an hour before meals can help increase your appetite, but avoid overly intense workouts to prevent fatigue that may affect your appetite; you can start with brisk walking or jogging.
Eating smaller, more frequent meals can enhance the gastrointestinal absorption of nutrients.
In addition to three main meals daily, you can add three snacks, but it’s best to avoid greasy, fried foods, excessive sweets, and sugary beverages to prevent the development of other chronic diseases.
You may consider consuming balanced nutritional supplements during snack times to help increase calorie and nutrient intake.
Smoking should be avoided, as it can affect taste sensitivity and appetite.
Most importantly, maintain a regular daily routine.
Wishing you peace and health! Sincerely, Dietitian Shih Kuei-Mei, Director of the Nutrition Department, Taoyuan Hospital, Ministry of Health and Welfare.

To enhance digestive absorption for healthy weight gain, it’s essential to focus on a combination of dietary strategies, lifestyle changes, and possibly some targeted exercises. Given your height of 165 cm and weight of 50 kg, it appears that you are underweight, and gaining weight in a healthy manner is important for your overall well-being.


Dietary Strategies
1. Increase Caloric Intake: To gain weight, you need to consume more calories than you burn. Aim for a calorie surplus of about 300-500 calories per day. This can be achieved by incorporating calorie-dense foods into your diet, such as nuts, seeds, avocados, whole grains, and healthy oils.

2. Frequent Meals: Instead of three large meals, consider eating five to six smaller meals throughout the day. This can help increase your overall caloric intake without making you feel overly full at any one time.

3. Protein-Rich Foods: Incorporate more protein into your meals, as it is essential for muscle growth and repair. Good sources include lean meats, fish, eggs, dairy products, legumes, and protein shakes. Aim for about 1.2 to 1.5 grams of protein per kilogram of your ideal body weight.

4. Healthy Fats: Include healthy fats in your diet, such as olive oil, coconut oil, and fatty fish. These not only provide essential fatty acids but also help increase your caloric intake.

5. Complex Carbohydrates: Focus on whole grains, legumes, and starchy vegetables. These foods provide energy and are often more nutrient-dense compared to simple carbohydrates.

6. Digestive Aids: Certain foods can enhance digestion and absorption. Probiotic-rich foods like yogurt, kefir, and fermented vegetables can help improve gut health. Additionally, foods high in fiber, such as fruits, vegetables, and whole grains, can aid in digestion.


Lifestyle Changes
1. Stay Hydrated: While it’s important to drink enough fluids, try to avoid drinking large amounts of water before meals, as this can fill you up and reduce your appetite.

2. Mindful Eating: Pay attention to your eating habits. Eating slowly and savoring your food can help improve digestion and absorption.

3. Limit Empty Calories: While it might be tempting to consume sugary snacks or junk food to gain weight, these often provide little nutritional value. Focus on nutrient-dense foods instead.


Exercise Considerations
1. Strength Training: Engaging in resistance training can help you build muscle mass, which is a healthy way to gain weight. Aim for 2-3 sessions per week, focusing on major muscle groups.

2. Light Cardio: While you want to gain weight, incorporating some light cardiovascular exercise can help stimulate your appetite. Activities like walking or cycling for 20-30 minutes a few times a week can be beneficial.

3. Post-Meal Activity: Light activities after meals, such as a gentle walk, can aid digestion without burning too many calories.


Specific Foods to Consider
- Bananas: High in calories and carbohydrates, they can be a great snack.

- Nut Butters: Spread on whole-grain bread or added to smoothies for an extra calorie boost.

- Dried Fruits: Such as dates, apricots, and raisins, are calorie-dense and nutritious.

- Smoothies: Blend fruits, vegetables, yogurt, and protein powder for a nutrient-rich, high-calorie drink.


Conclusion
Gaining weight in a healthy way requires a strategic approach to diet and lifestyle. By focusing on nutrient-dense foods, increasing your caloric intake, engaging in strength training, and making mindful eating choices, you can enhance your digestive absorption and achieve your weight gain goals. If you find it challenging to gain weight despite these efforts, consider consulting a healthcare professional or a registered dietitian for personalized guidance.
