Too thin with a small frame?


My height is 174 cm and my weight is 56 kg, giving me a BMI of 18.
I feel that I am really too thin.
I eat three regular meals and have checked with a metabolic specialist, and everything is fine.
I don't know how to gain weight.
My bone structure, particularly the sides of my pelvis, is flat.
Is it already set in shape, or can it gradually become larger?

1.
Based on your height, maintaining a weight between 56 kg and 72 kg is considered within the normal weight range.

2.
At 22 years old, you are at an age of peak activity and higher energy expenditure, so having a leaner physique is quite normal.

3.
If you have a habit of exercising, your daily caloric needs can exceed 2300 calories, and you can increase the frequency of snacks to meet your caloric requirements.

4.
Your skeletal structure is already established; if you want to gain muscle, you can engage in strength training, as resistance training can also enhance bone density.

To gain weight and build a healthier body frame, especially when you have a BMI of 18, it’s essential to focus on both your diet and exercise regimen. Here are some strategies to help you achieve your goals:

1. Increase Caloric Intake:
To gain weight, you need to consume more calories than your body burns. This can be achieved by:
- Eating More Frequently: Aim for five to six smaller meals throughout the day rather than three large ones. This can help you increase your overall caloric intake without feeling overly full.

- Choosing 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, cheese, and yogurt can add calories and protein.

- Whole Grains: Foods like quinoa, brown rice, and whole-grain bread are good sources of carbohydrates and calories.

- Healthy Oils: Incorporate olive oil, avocado oil, or coconut oil into your meals to increase caloric density.


2. Protein Intake:
Protein is crucial for muscle growth. Aim for a protein-rich diet to help build muscle mass. Good sources include:
- Lean Meats: Chicken, turkey, and lean cuts of beef.

- Fish: Salmon and tuna are not only high in protein but also provide healthy omega-3 fatty acids.

- Legumes: Beans, lentils, and chickpeas are excellent plant-based protein sources.

- Protein Supplements: If you struggle to meet your protein needs through food alone, consider protein shakes or bars.


3. Strength Training:
Incorporating strength training into your routine is vital for building muscle mass. Here are some tips:
- Focus on Compound Exercises: Exercises like squats, deadlifts, bench presses, and rows work multiple muscle groups and can help you gain strength and mass.

- Progressive Overload: Gradually increase the weight you lift over time to challenge your muscles and stimulate growth.

- Consistency is Key: Aim for at least 2-3 strength training sessions per week, focusing on different muscle groups.


4. Monitor Your Progress:
Keep track of your weight and body measurements to see how your body responds to dietary changes and exercise. Adjust your caloric intake and exercise routine based on your progress.


5. Consult a Professional:
Since you mentioned that you have already checked with a metabolism specialist, consider consulting a registered dietitian or a nutritionist who can provide personalized dietary advice tailored to your specific needs and goals.


6. Bone Structure and Body Frame:
Regarding your concern about your pelvic structure and whether it can change, it’s important to note that bone structure is largely determined by genetics and cannot be significantly altered. However, building muscle around your hips and thighs can create a more balanced appearance. Exercises like squats, lunges, and hip thrusts can help develop the muscles in those areas.


7. Stay Hydrated:
While focusing on calorie intake, don’t forget to drink plenty of water. Staying hydrated is essential for overall health and can aid in digestion and nutrient absorption.


Conclusion:
Gaining weight and building a healthier body frame requires a combination of increased caloric intake, a focus on nutrient-dense foods, strength training, and consistency. Remember that changes take time, so be patient with yourself as you work towards your goals. If you find it challenging to make progress, seeking guidance from a healthcare professional can provide additional support and resources.
