Dear Ujjawal, Thank you for the question

Protein is an important component of your daily balanced diet and inadequate intake may lead to loss of energy, fatigue, improper functioning of immune system etc. Protein is an important component for weight loss as it delays gastric emptying and gives a feeling of satiety. but it should also include appropriate inclusion of other nutrients. High protein foods help in maintaining lean body or muscle mass. 

However excess consumption of protein in the daily diet can cause various side effects and health related issue.  For guidance on higher protein requirements for specific health or fitness needs please contact a health care professional or any registered dietitian

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 2nd 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.



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.

As a general dietary guideline, for an apparently healthy individual/ with no specific health or nutrition needs and/or metabolic condition it is recommended to consume 2000kcal/d and for men, the RDA for protein requirement is 54g/d and for fiber it is 30g/d.

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. 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.
