How to gain weight?


I was quite robust during my childhood, but I started to lose weight in middle school.
I've always wanted to gain weight, but I can't seem to put on any.
I eat as much as those around me who are heavier, yet I still can't gain weight.
Should I see a doctor?

Hello: Since I do not know your height and weight, I cannot determine if you are truly underweight.
If your daily caloric intake exceeds your body's daily caloric needs, you will gradually gain weight.
For example, if you consume an additional 500 calories per day, you could gain 0.5 kilograms in a week, and after a month, you could gain 2 kilograms.
However, to rule out any physiological factors that may affect your weight, it is advisable to consult a doctor, as this is the most accurate approach.
You may also visit a nutrition consultation clinic to speak with a dietitian, which will be beneficial for you.
Wishing you good health, Miaoli Hospital Dietitian Qi Minghua.

Gaining weight can be a challenging process for some individuals, especially if they have a naturally high metabolism or underlying health issues. If you find yourself struggling to gain weight despite consuming a sufficient amount of food, it may be beneficial to explore several factors that could be influencing your situation.

Firstly, it’s important to assess your overall health. If you have experienced a significant change in weight, such as losing weight during your middle school years, it may be worth consulting with a healthcare professional. A doctor can evaluate your medical history, perform necessary tests, and rule out any potential underlying conditions that could be contributing to your difficulty in gaining weight. Conditions such as hyperthyroidism, diabetes, gastrointestinal disorders, or malabsorption syndromes can affect your ability to gain weight.

In addition to medical factors, consider your dietary habits. While you mentioned that you eat as much as those around you, the quality and composition of your diet matter significantly. Focus on incorporating calorie-dense foods into your meals. Foods such as nuts, seeds, avocados, whole grains, and healthy oils can provide more calories without requiring you to eat large volumes of food. Additionally, consider increasing your protein intake, as protein is essential for muscle growth and repair. Foods like lean meats, dairy products, legumes, and protein-rich snacks can help you build muscle mass, which contributes to weight gain.

Another aspect to consider is your physical activity level. While exercise is important for overall health, excessive cardio can lead to weight loss rather than gain. If you are engaging in high levels of physical activity, consider incorporating strength training into your routine. Strength training helps build muscle, which can contribute to weight gain. Aim for a balanced approach that includes both cardiovascular and resistance exercises.

Timing and frequency of meals can also play a role in weight gain. Instead of three large meals, try eating smaller, more frequent meals throughout the day. This can help increase your overall calorie intake without making you feel overly full at any one time. Additionally, consider having snacks that are high in calories and nutrients between meals.

Lastly, it’s essential to address any psychological factors that may be affecting your eating habits. Stress, anxiety, or a busy lifestyle can impact your appetite and eating patterns. If you find that emotional factors are influencing your ability to eat enough, consider speaking with a mental health professional who can provide support and strategies to manage these challenges.

In summary, if you are struggling to gain weight, it is advisable to consult with a healthcare provider to rule out any underlying medical conditions. Focus on a balanced diet rich in calorie-dense and nutrient-rich foods, incorporate strength training into your exercise routine, and consider the timing and frequency of your meals. If psychological factors are at play, seeking support from a mental health professional may also be beneficial. Gaining weight is a gradual process, and with the right approach, you can achieve your goals in a healthy manner.
