Dear Vedant, Thank you for the question

Adolescence witnesses speedy physical and emotional development. These changes also demand for specific nutrient requirements. It is very important to consume a well-balanced diversified diet and engage in regular physical activity to support growth, pubertal changes, bone developments and increased haemoglobin production.

Reference ideal body weight and height for 13-year-old male can be considered as 43.3 kg and 157 cm height.

According to the mentioned weight your son seems to be underweight for his reference ideal body weight.

Physical growth and development of an individual involves various factors like Genetics, Gender, Nutrition & Physical activity. Consuming well balanced diet with all food groups in appropriate amounts will help you reach all your daily nutrient requirements and maintain a healthy development. 

Some of the essential nutrients such as protein, calcium, magnesium, vitamin D etc, contribute to the development and maintenance of strong, healthy bones. Some of the good sources of these nutrients include milk & milk products, egg, dark green leafy vegetables, legumes.

Recommended daily allowance for calcium is 1000mg and for Vitamin D is 600IU (15mcg) per day for 13-year-old male

The causes of underweight or unintended weight loss can be due to genetics, inadequate food intake, stress, hormonal imbalance, malabsorption or other underlying health condition.

In any weight management programme, it is very essential to consume a healthy diversified balanced diet with few dietary modifications and regular physical activity. For weight gain it is essential to focus on your daily balanced diet with high calorie, high protein, and regular meals. With any weight gain diet, changes take time to reflect as your body requires sufficient time to adapt to the changes in order to show results.

A high calorie and high protein diet is recommended for weight gain. High protein foods give a feeling of satiety, delay gastric emptying and help in maintain lean body or muscle mass . Daily protein requirement should ideally be followed as 0.8-1g per kg body weight. You can include non-vegetarian sources of protein such as chicken, eggs, fish, prawns etc and vegetarian sources Milk & milk products like paneer, Legumes, lentils, beans (chickpeas, kidney, mung, pinto etc.), peas (green, split, etc.), soybeans (and products made from soy: tofu, tempeh, etc.), peanuts, almonds, pistachios, cashews, walnuts, hazelnuts, pecans, hemp seeds, squash and pumpkin seeds, sunflower seeds, flax seeds, sesame seeds, chia seeds as a part of your daily balanced diet
