Dear Sari, 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 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.

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. Some of the sources of high protein include pulses, lentils, milk, paneer, soybean, eggs, lean meat, nuts & seeds etc.
Here are few guidelines that can be considered
- 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.

- Do not skip meals. Eat small frequent meals.
- Three major meals a day with healthy nutritious snacks in between is preferred.

- Try to follow a good sleep regimen in terms of both quantity and quality.

A healthy lifestyle management including a good balanced diet, adequate hydration, regular physical activity and hygiene & stress management is key to maintain a good digestive health. It is also important to ensure adequate fiber intake which is essential for a healthy gut and overall digestive health.
Gut microbiota includes a diverse community of bacteria in human gut, they carry out various functions that influences our overall health. The functions include, nutrient metabolism, natural defense against infections and regulation of immune system.
For managing a healthy gut it is important to consume a diversified balanced duet at regular intervals, maintain hydration and include dietary fibre in your daily diet. It is also important to engage in regular physical activity and include prebiotic and probiotics in your daily diet Prebiotics are food components that confer benefits to the host by selectively stimulating the growth of beneficial gut microbiota whereas Probiotics are beneficial bacteria that incur positive effects on human health. They are present in the human gut and are also taken through food products such as yogurt, fermented foods, dietary supplements etc.
Prebiotics naturally exist in different foods including, asparagus, garlic, chicory, onion, honey, banana, barley, tomato, rye, soybean, human’s and cow’s milk, peas, beans, etc.
The common sources of probiotics are yogurt, cultured buttermilk and cheese. The other foods that are produced by bacterial fermentation are, tempeh, sauerkraut, sour dough, bread etc. Look for food products labelled ‘Probiotic’, ‘Probiotic food’, ‘Contains Probiotics’, ‘with Probiotics’ etc.

This substantive and continuing shift in body temperature is a marker for metabolic rate. Heat is a by-product of metabolic processes. A brain region called the hypothalamus is responsible for regulating body temperature. It checks the body’s current temperature against its normal temperature and then regulates it.
When the body is too hot, regulation occurs through sweating to cool it down. When it is too cold, the hypothalamus triggers shivering to warm it up.
Here are few tips to regulate body temperature
• Drinking liquids like water or tender coconut water can help regulate body temperature. The regular intake of fluids can also prevent dehydration, which can increase body heat.
• Swimming in cool water, taking a lukewarm bath, or applying cold water to the body can reduce body temperature. In these cases, body temperature will decrease as a result of conduction.
• Applying cold water or ice to strategic points on the body where the veins are close to the surface — such as the wrists, neck, chest, and temples — can quickly lower the temperature of the blood running through these veins. This allows the body to feel cooler.
• The body releases heat when it moves. In hot temperatures avoid heavy exercise and limit movement.
• Heat passes more easily through some fabrics than others. Natural fabrics, such as cotton and linen, allow heat to escape from the body more easily than synthetic fabrics, such as acrylic and nylon.
• High body heat may be due to an overactive thyroid. When this is the case, a person might also notice other symptoms, such as a rapid heart rate, sweating and confusion for which we recommended you to contact your health care professional
