Dear Anchal Pathak, Thank you for the question

WHO has given different BMI (Body mass index) classifications to categorise adults into different weight categories. BMI is a simple index of weight-for-height. It can be considered as a 2^nd level indicator of overall health.

It can be calculated using a simple formula of BMI = Weight (kg) / Height (m²)

Following is the WHO BMI Classification

18.5 to 24.9 - Normal

Less than 18.5 - Underweight

25 to 29 - Overweight

Above 30 - Obese

As per WHO BMI (Body Mass Index) classification, a person weighing less than 18.5 kg/m2 is considered underweight.

According to your mentioned Height & weight your BMI is 16.03kg/m2 which is under the Underweight BMI range as per WHO classification.

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 which may require medical assistance.



An ideal weight management program such as weight gain involves lifestyle management including dietary modification, regular physical activity, hydration and good sleep cycle. 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 protein per kg body weight.

Here are some vegetarian sources of protein 

• 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.
• Nuts and Seeds: almonds, pistachios, cashews, walnuts, hazelnuts, pecans, hemp seeds, squash and pumpkin seeds, sunflower seeds, flax seeds, sesame seeds, chia seeds.
• Whole Grains:  wheat, quinoa, rice, wild rice, millet, oats, buckwheat,
• Other: while many vegetables and fruits contain some level of protein, it’s generally in smaller amounts than the other plant-based foods. Some examples with higher protein quantities include corn, broccoli, asparagus, brussels sprouts, and artichokes.

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.

Here are few guidelines that can be considered for weight gain

• Having a Healthy Diversified Balanced Diet that includes all the food groups in the right quantity which thereby provides you with all the essential macro and micro nutrients that your body requires daily for proper functioning. Include energy dense foods, keeping in mind the daily needs.
• 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, 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

• 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.

Regular gastritis, bloating can be a symptom of gastrointestinal digestive issues such as indigestion, constipation, IBS, intolerances etc., and/or due to an underlying health condition which requires medical attention.
