Dear Gursahib Singh, Thank you for the question

Adolescence or teen age is acritical period of our lives in which our body undergoes rapid changes, growth and development. It is very essential to consume a healthy balanced diet with adequate amount of protein and other nutrients such as calcium, iron, vitamin D etc., which will help support growth, development, pubertal changes and strong bones.

Reference ideal body weight for 17-year-old male can be considered as 50.7-62.3 kg with 163.1-176.9 cm height.

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. Daily protein requirement should ideally be followed as 0.8-1g per kg body weight. Some of the sources of high protein include pulses, lentils, milk, paneer, soybean, eggs, lean meat, nuts & seeds etc.

Here are a few general Dietary guidelines to be considered for weight gain

• Adolescence represents a period of active life, hence no meal of the day should be missed to sustain energy and growth spurts
• Having a Healthy Diversified Balanced Diet that includes all the 5 food groups (cereals, pulses, fruits, vegetables, milk & milk products) in the right quantity which thereby provides you with all the essential macro and micro nutrients that your body requires daily for proper functioning.
• Maintain a positive energy balance where the calorie intake should be more than the energy expenditure.
• Include energy dense foods, keeping in mind the daily needs. Some of the energy dense foods include Whole wheat, Multigrain, millets, dairy products, nuts, colocasia leaves, banana, raisins, pulses/lentils etc.
• Do not skip meals. Eat small frequent meals.
• Three major meals a day with healthy nutritious snacks in between is preferred.
• Try to increase the serving size and portion size gradually and systematically
• Include healthy fats from nuts and seeds.
• Drink at least 8 glasses of water per day to maintain hydration
• Indulging in physical activity can help in increasing the appetite and give a feeling of hunger.
• Try to follow a good sleep regimen in terms of both quantity and quality.

Less than 18.5 - Underweight

25 to 29 - Overweight

Above 30 - Obese

Dear SHIPRA Taneja, Thank you for the question

Dietary fiber also known as roughage is a type of carbohydrate, It’s a component of the plant which is resistant to digestion by the enzymes in the human system. It is considered to be an essential component of your daily balanced diet.



There are two types of fibers like soluble (from in oats, apple), insoluble (from whole grain), foods like multigrain will aid the benefit of providing both the types of fibre. Another classification is prebiotic fibres (ex: onion, green banana, chicory), which occur naturally in various foods we eat in our daily diet.

Some other benefits for diets with a high content of fibre include:

• Improves bowel function

• Adds bulk to stool and promotes regularity

• Helps support growth of healthy gut bacteria and overall digestive health.

• Fiber aids in providing satiety and keeps you full for longer which helps with reduced calorie intake and aids in weight management.

Some of the good sources of fiber are as follows:

• Whole grains- whole wheat, millets, multigrain, wheat bran, oats etc.

• Vegetables such as green beans, peas, cauliflower, garlic, carrot, tomato etc.
• Fruits including banana, apple, and citrus fruits like orange & sweet lime.
• Dried beans, Legumes, Nuts & Seed

Recommneded Daily Allowance of fiber for children is as follows:

For children age 7-9 - 26g per day

For 10-12 yrs. boys – 33g and for girls 30g per day

In packaged food product read their labels to look for “source of fiber” “rich in fiber”, “high fiber” etc., to be included as a part of your overall diversified daily balanced diet.

Hope we have answered your query.
