Why Can't I Gain Weight? Exploring Nutrition and Health Factors - Nutrition

Not gaining weight may be due to other underlying factors?


Currently, my weight is about 58-60 kg and my height is 174 cm.
However, it's strange that my weight doesn't increase even when I eat a lot, and I don't seem to gain muscle from working out; I just become more toned.
Additionally, I feel very fatigued when I consume foods with stronger flavors, to the point where I feel like I can't stay awake without sleeping.
I'm concerned that this might be related to kidney function, as I've noticed that I feel particularly tired after consuming foods high in MSG, salt, or sugars.
My skin also appears to be more dull.
I now want to gain weight, and I have important tasks to focus on.
I hope to regain my previous energy levels so that I don't feel fatigued and can concentrate better.

Hello! Your ideal weight range is between 60 to 73.2 kilograms.
Regarding the various discomforts you mentioned, it is advisable to seek medical examination for kidney function, liver function, and blood glucose levels.
Additionally, please assess whether your life stress is excessive.
If it is due to high stress, it would be best to avoid or reduce the sources of that stress.
Engaging in appropriate physical activity can not only help regulate your physical and mental well-being but also promote strength, endurance, and appetite.
Sincerely, Dietitian Shih Kuei-Mei, Director of the Nutrition Department, Taoyuan Hospital, Ministry of Health and Welfare.

More Info


Gaining weight can be a complex issue influenced by various factors, including metabolism, dietary habits, physical activity, and overall health. Based on your height (174 cm) and weight (58-60 kg), your Body Mass Index (BMI) falls within the normal range, but it is on the lower end. If you're struggling to gain weight despite eating more and exercising, several potential explanations could be at play.


Metabolism and Body Composition
One of the primary reasons you may not be gaining weight is a high metabolic rate. Some individuals naturally burn calories faster than others due to genetic factors, muscle mass, and activity levels. Muscle tissue burns more calories at rest compared to fat tissue, so if your workouts are primarily strength training, you may be building muscle without a significant increase in weight. This could explain why you feel more toned and fit but do not see a corresponding increase on the scale.


Dietary Considerations
Your experience of feeling fatigued after consuming foods high in salt, sugar, or MSG could indicate a sensitivity to these ingredients. High sodium intake can lead to dehydration, which may cause fatigue and a feeling of sluggishness. Similarly, excessive sugar can lead to energy spikes followed by crashes, contributing to feelings of tiredness. If you notice that certain foods make you feel worse, it may be beneficial to limit those and focus on a balanced diet rich in whole foods, including lean proteins, healthy fats, and complex carbohydrates.


Nutritional Deficiencies
If you're not gaining weight, it may also be due to insufficient caloric intake or a lack of essential nutrients. To gain weight healthily, you need to consume more calories than you burn. This can be achieved by increasing portion sizes, adding snacks between meals, and choosing calorie-dense foods such as nuts, avocados, and whole grains. Additionally, consider incorporating protein-rich foods to support muscle growth, especially if you're engaging in resistance training.


Health Concerns
Your concerns about kidney function are valid, especially if you are experiencing unusual fatigue and skin changes. It would be wise to consult a healthcare professional to evaluate your kidney function and overall health. Blood tests can help assess kidney health, liver function, and blood sugar levels, which could provide insights into your fatigue and dietary responses.

Stress and Lifestyle Factors
Stress can significantly impact your appetite and energy levels. If you're under considerable academic or personal stress, it may affect your eating habits and energy expenditure. Engaging in stress-reducing activities such as yoga, meditation, or even light exercise can help improve your overall well-being and may positively influence your appetite.


Recommendations for Weight Gain
1. Increase Caloric Intake: Aim to consume more calories than you burn. This can be done by adding healthy snacks, increasing portion sizes, and choosing calorie-dense foods.


2. Focus on Nutrient-Dense Foods: Incorporate foods that are high in nutrients and calories, such as nuts, seeds, avocados, and whole grains. Protein-rich foods like chicken, fish, eggs, and legumes are also essential for muscle growth.

3. Monitor Your Diet: Keep a food diary to track your caloric intake and identify any patterns that may be affecting your weight. This can help you make informed dietary choices.

4. Stay Hydrated: Ensure you are drinking enough water, as dehydration can contribute to fatigue. However, be mindful of high-sodium foods that can lead to dehydration.

5. Consult a Professional: If you continue to struggle with weight gain, consider consulting a registered dietitian or a healthcare provider. They can provide personalized advice based on your health status and dietary needs.

6. Exercise Wisely: While strength training is beneficial for muscle gain, ensure you are not overtraining, which can lead to fatigue. Balance your workouts with adequate rest and recovery.

In conclusion, gaining weight is not solely about eating more; it involves a holistic approach that considers your overall health, dietary habits, and lifestyle factors. By addressing these areas, you can work towards achieving a healthier weight while improving your energy levels and overall well-being.
